Wool ripped from this blogger’s eyes

June 23, 2009

One of my DDT blog post alerts turned up this one at Butter Side Down, which is as close to perfect in accuracy and conciseness as I have seen lately.

Here’s a question that I was asked this weekend, one which I’ve been asked more than once: how anyone can justify the ban on DDT when millions of people are dying of malaria?

It’s a good question.

Unfortunately, it’s the wrong question. It’s wrong because it’s based on three premises:

  1. DDT has been banned;
  2. In areas where mosquitoes are endemic millions are needlessly suffering and dying from malaria deaths that are preventable if spraying DDT is allowed; and
  3. DDT is a panacea that strikes down mosquitoes without fail.

All three premises are wrong.

If this guy woman can be so wise, why cannot others at least follow him her?


$36 million to clean up DDT mess

June 12, 2009

One more reminder that DDT is a deadly substance:  EPA announced a program to cap render harmless the largest DDT dump, off the coast of California.

Jeff Gottlieb writes in The Los Angeles Times:

The federal Environmental Protection Agency on Thursday proposed spending at least $36 million to clean up the world’s largest deposit of banned pesticide DDT, which lies 200 feet underwater off the Palos Verdes Peninsula.

Montrose Chemical Corp., which was based near Torrance, released 110 tons of DDT and 10 tons of toxic PCBs into the sewers from 1947 through 1971. The chemicals then flowed into the Pacific.

What do you think?  A substance that is deadly, makes one of the largest and deadliest Superfund sites in America, and costs $36 million in taxpayer smackaroons just to seal up so it won’t kill again — is it “perfectly safe” as the advocates claim?

This is one subject you will not see discussed at Steven Milloy’s sites, Junk Science, nor Green Hell.  You won’t find the Chronically Obsessed with Rachel Carson (COWRC) mentioning this clean-up.

Remind them.

Public hearings on this plan are scheduled for June 23 and 25.

Bed nets save lives, fighting malaria without DDT

May 25, 2009

Infant in Nigeria sleeps beneath an insecticide-treated bednet that prevents the transmission of malaria, a disease that kills thousands of children in Africa annually.  Nothing But Nets press release

Infant in Nigeria sleeps beneath an insecticide-treated bednet that prevents the transmission of malaria, a disease that kills thousands of children in Africa annually. Nothing But Nets press release

According to Nothing But Nets:

Studies show that use of insecticide-treated bed nets can reduce transmission as much as 90% in areas with high coverage rates. Bed nets prevent malaria transmission by creating a protective barrier against mosquitoes at night, when the vast majority of transmissions occur. The African malaria mosquitoes generally bite late at night or early morning, between 10:00 p.m. and 4:00 a.m. A bed net is usually hung above the center of a bed or sleeping space so that it completely covers the sleeping person. A net treated with insecticide offers about twice the protection of an untreated net and can reduce the number of mosquitoes that enter the house and the overall number of mosquitoes in the area.


Heartland on bedbugs: DDT stupidity, all the way to 11

May 25, 2009

The Heartland Institute is charitably called a “think tank” sometimes.  In their latest screed against science and people who wish to protect the environment, there is no evidence of thinking, however.  It’s all tank.

The headline says it all: “Bedbug Outbreak Hits All 50 States Thanks to DDT Ban.”

With all their reading on bedbugs, they never noticed the many notes that DDT stopped working against bedbugs more than 50 years ago? Who is going to tell them that DDT doesn’t work? Or, is this a talisman, an understanding that none of the solutions proposed by Heartland Institute will work? First they flirt with intelligent design, then they lose their senses altogether.  There’s an omen there.

Remember the scene in “Spinal Tap?” Heartland Institute on bedbugs is stupid, turned up to 11.  Heartland Institute doesn’t allow comments, probably because they can’t stand the laughter.


Eradicate malaria – here’s how

Applying evolution theory to defeat malaria

May 3, 2009

If the theory works, why not use it, eh?

One of the most serious problems with the use of DDT is that it tends to drive insects to evolve defenses to pesticides very quickly.  Almost every mosquito on Earth today has alleles that allow it to digest DDT, rather than be poisoned by it.  These alleles arose shortly after DDT was put into use against mosquitoes, and by the mid-1960s had made fruitless the malaria eradication campaign worked by the World Health Organization.

Evolution can be used to the benefit of humans and the eradication of malaria, too.

Voice of America (remember that agency?) tells the story of Andrew Read, a researcher at Penn State University, who realized that the deadliest mosquitoes are old ones — malaria has to survive for about two weeks in the mosquito in its life cycle in order to be infectious to humans.  If the mosquito dies before that time, the malaria can’t be transmitted.

Read’s proposal?  He has a fungus that takes a couple of weeks to work, but which kills the mosquito once it gets going.

In other words, Read doesn’t worry about getting all the mosquitoes.  His method, if it works, will kill only the mosquitoes most likely to carry malaria.

Plus, since most of the breeding cycle of these mosquitoes will be completed, it won’t drive the mosquitoes to evolve around the problem.

“The good thing about just killing the old ones is that most mosquiotoes will have done most of their reproduction before you kill them, and that means the susceptible mosquitoes will indeed continue to breed, so you still have susceptible mosquitoes, and your insecticides then just work against the old guys, removing them, and they are the dangerous ones. So under those circumstances, you don’t get the evolution of insecticide-resistant mosquitoes.”

He and his colleagues have been testing a kind of fungus that makes mosquitoes sick over the course of several weeks. And it eventually kills the oldest and most infectious mosquitoes.

“The name of the game is not mosquito control. It’s actually malaria control,” Read explains. “So if you just remove the old ones, you still have lots of young, non-dangerous mosquitoes around, but you have controlled malaria.”

Read says this fungus is about 98 to 99 percent effective at killing old mosquitoes in the lab. Now he says he needs to test this fungal insecticide in villages areas where malaria is prevalent, to see whether fewer people get the disease, even if they’re still getting bitten by mosquitoes.

Read and his team propose a new concept of mosquito control, based on what we know about the life cycles of mosquitoes and how they evolve, rather than just looking for one more “new” pesticide to which the insects will soon become resistant.  Read’s article appears in the open-access Public Library of Science (PLoS), published April 7, 2009:  “How to Make Evolution-Proof Mosquitoes for Malaria Control.” His coauthors are Penelope A. Lynch and Matthew B. Thomas.

Summary

Insecticides are one of the cheapest, most effective, and best proven methods of controlling malaria, but mosquitoes can rapidly evolve resistance. Such evolution, first seen in the 1950s in areas of widespread DDT use, is a major challenge because attempts to comprehensively control and even eliminate malaria rely heavily on indoor house spraying and insecticide-treated bed nets. Current strategies for dealing with resistance evolution are expensive and open ended, and their sustainability has yet to be demonstrated. Here we show that if insecticides targeted old mosquitoes, and ideally old malaria-infected mosquitoes, they could provide effective malaria control while only weakly selecting for resistance. This alone would greatly enhance the useful life span of an insecticide. However, such weak selection for resistance can easily be overwhelmed if resistance is associated with fitness costs. In that case, late-life–acting insecticides would never be undermined by mosquito evolution. We discuss a number of practical ways to achieve this, including different use of existing chemical insecticides, biopesticides, and novel chemistry. Done right, a one-off investment in a single insecticide would solve the problem of mosquito resistance forever.

Among reasons you may want to bookmark that publication:  In the opening paragraphs the authors discuss how Indoor Residual Spraying drives mosquito resistance to pesticides, with citations to the most recent and most powerful studies.  This is the case against bringing back DDT in a big way.


Making a false case against Gardasil

May 2, 2009

Especially after working for so many years alongside the big drug companies working health legislation in the Senate, and after later policy work for private companies that made the point again that Big Pharma doesn’t always act scrupulously (remember Oraflex?), I’m no particular fan of the big companies.

But I am a big fan of getting the facts before making claims against them.  I also stand in awe of the accomplishments of medicine, including Big Pharma, in so many areas.  My oldest brother had polio as a kid, and it haunted him to his death.  Polio vaccine was a great advance.  I survived a bout of scarlet fever as an infant, but as a result I am particularly vulnerable to certain infections now; I stand in awe of a $10 prescription that literally saves my life.

Get the facts.  We’re talking saving lives here — be sure you’re accurate.

There is a nasty campaign against modern medicine claiming that vaccines and other injectable preventives do not work, or do much greater harm than is revealed.

One victim of this unholy smear campaign is the Merck Drug company, and its anti-cancer vaccine Gardasil.  This vaccine has been the topic of much controversy here in Texas.  I’ve written about it before.

So I was shocked once again browsing Neil Simpson’s blog (looking for a post that disappeared, it now seems), to discover this statement of concern from Mr. Simpson:

Gardasil Moms: If one of those 32 dead girls or women was your daughter. . . – I wouldn’t rush out and get the vaccine for your girls just yet.

32 dead girls from the vaccine?  Mr. Simpson fails to tell the whole story.  Here’s what CDC actually said:

As of December 31, 2008, there have been 32 U.S. reports of death among females who have received the vaccine. There was no common pattern to the deaths that would suggest that they were caused by the vaccine. [emphasis added]

This isn’t the first time opponents of Gardasil have failed to report accurately the deaths accounted for in the trials and use of the drug.  In previous outings, critics of the drug have done such bizarre things as counting deaths of people who never took the drug, as deaths perhaps caused by the drug.

For example, from the numbers available when I wrote about this in May 2007:

  • Of the 17 deaths reported in the clinical trials,  7 of them came from the placebo group.  That’s right:  Only 59% of the reported deaths were in the group that got Gardasil.  41% of the reported deaths came from people who had received no Gardasil vaccine.
  • 7 of the deaths were from auto accidents, 4 in the Gardasil group, 3 in the placebo group.
  • Most of the deaths were from causes generally thought to be unrelated to to Gardasil, including suicide and cancer.

Don’t you think that, in blaming deaths on a dosage of a vaccine, one should not count deaths to people who did not get the vaccine? So, can we trust numbers from a slander campaign that keeps repeating falsehoods for two years, though the data are freely available?

If you check the Gardasil site now, you’ll find more deaths have been added.  Merck follows up reports of problems, and they update the information when they can, as required by law.

There are now 24 deaths reported in Merck’s literature, 16 in the Gardasil group, and 9 in the control group; the Gardasil deaths have risen to 64% of total deaths; some new causes are added in.  But there is no glaring indictment of Gardasil, and it still seems to me to be rather unethical to claim, as Simpson’s source does, that deaths by auto accident can be attributable to Gardasil, especially when an almost equal number of auto accident deaths occurred in the control group.

Here is what the CDC says, unedited:

Reports to VAERS Following HPV Vaccination

As of December 31, 2008, more than 23 million doses of Gardasil were distributed in the United States.

As of December 31, 2008, there were 11,916 VAERS reports of adverse events following Gardasil vaccination in the United States. Of these reports, 94% were reports of events considered to be non-serious, and 6% were reports of events considered to be serious.

Based on all of the information we have today, CDC continues to recommend Gardasil vaccination for the prevention of 4 types of HPV. As with all approved vaccines, CDC and FDA will continue to closely monitor the safety of Gardasil.  Any problems detected with this vaccine will be reported to health officials, healthcare providers, and the public, and needed action will be taken to ensure the public’s health and safety.

23 million doses of the vaccine, high efficacy in preventing cancer and genital warts, only 6% serious events reported, no deaths that doctors can connect to the vaccine.

In the time Simpson writes about, several thousand women died of cervical cancer; he’s posing 32 deaths unrelated to the vaccine and saying it’s dangerous, when the facts show exactly the opposite.  Is that ethical?

It’s creationism syndrome:  Religionists decide on their conclusions, sometimes supported by scripture, but sometimes also supported by misreadings of scripture; then they set off in search of evidence to support their pre-conceived conclusion, and they step over real data and alter evidence to make sure their pre-conceived conclusions get the support.

In other words, they use doctored data.  Neil Simpson’s sources are using doctored data again.  Shame on them.  I’m sure he’ll correct it in his blog.

______________

Update, May 3: Simpson has not corrected his blog yet.  As an indicator of the issues at stake, you may want to look at CDC figures on cervical cancers, many of which are prevented completely by Gardasil.  Actually trends on the disease are encouraging:

Cervical cancer used to be the leading cause of cancer death for women in the United States. However, in the past 40 years, the number of cases of cervical cancer and the number of deaths from cervical cancer have decreased significantly. This decline largely is the result of many women getting regular Pap tests, which can find cervical precancer before it turns into cancer.1

According to the U.S. Cancer Statistics: 2005 Incidence and Mortality Web site, 11,999 women in the U.S. were told that they had cervical cancer in 2005,* and 3,924 women died from the disease.2 It is estimated that more than $2 billion is spent on the treatment of cervical cancer per year in the U.S.3

Cervical cancer strikes disproportionately at minority women:

Even though these trends suggest that cervical cancer incidence and mortality continue to decrease significantly overall, and for women in some racial and ethnic populations, the rates are considerably higher among Hispanic and African-American women.

Found it! Hoax Museum is right: Zinsser got it wrong

January 4, 2009

Found it!  [See previous post.]

I had done a search for Zinsser’s book, Rats, Lice and History, many weeks ago, and come up dry (how many weeks?).

But a more careful search in Google Books turned up a copy of most of the text, from Read Books — and in that edition, appearing to have been published in London*, there is a page 285!

On that page 285, there is the quote cited, claiming that the bathtub did not come to America until about 1840.

The quote is found in chapter XVI, in the first section, a couple of paragraphs prior to the second section — page 217 in the editions of the book I have.

So, the Hoax Museum is right in saying Zinsser was hoaxed, too.  Zinsser’s book appeared first in 1935, with plenty of time for Mencken’s 1917 hoax to have spread into sources Zinsser trusted.

Even the best can be taken in by a hoax crafted well enough, or on a subject obscure enough.

Hoaxes on hoaxes: Bathtub hoax debunkers start a new hoax?

January 4, 2009

[If you’re interested in the hoax aspect, see this update post.]

Is this just an error, or a new hoax on the way to debunking an old one?  This is a story of an insider’s hoax, or an interesting error.

It’s from the Museum of Hoaxes.  Surely they would be careful about such matters, no?

The Museum of Hoaxes’ History of the Bathtub is largely a history of H. L. Mencken’s famous 1917 hoax history of the bathtub, in which he claimed Millard Fillmore had bravely led America to indoor bathing by installing a bathtub in the White House in 1853.

Readers of this blog well know this story.  Fillmore wasn’t the first to put a bathtub in the White House.  He wasn’t the first to put plumbing in the White House.  He wasn’t the first to put a plumbed bathtub in the White House, nor the first to run hot water to it. Anything in Mencken’s column that squares with history did so accidentally.  Mencken was making a big joke.

And one of the little delights of reading history is finding people who should know better, who have been suckered in by Mencken’s hoax.

So of course I read the piece at the Hoax Museum.

What ho!  Here is a section that discusses how the hoax refuses to die:

Curtis MacDougall, writing in 1958, reported finding fifty-five different instances since 1926 of Mencken’s bathtub history being presented to audiences as fact. Some of the examples that MacDougall collected follow:

October, 1926: Scribner’s included an article, “Bathtubs, Early Americans,“ by Fairfax Downey, based almost entirely on Mencken’s story.

March 16, 1929: In “Baltimore Day by Day,“ by Carroll Dulaney, in Mencken’s own newspaper, the Baltimore Evening Sun, the story is told under the heading, “Painting the Lily.“

September 26, 1929: The Paris, France, edition of the New York Herald rewrites an article by Ruth Wakeman in the New York Sun entitled, “Americans Once Frowned on Bathtubs, Condemning Them for Fancied Hazards.“

December 1, 1931: The Tucson, Arizona, Daily Star interviews C.R. King, manager of the Standard Sanitary Manufacturing Company branch in Tucson, on the imminent birthday of the bathtub. Mr. King, who according to the Star “had apparently studied the matter considerably,“ hands out the same old facts, which are printed under a two-column head, “Bathtub Will Have Birthday in America During December.“

April 27, 1933: A United Features Syndicate feature, “How It Began,“ by Russ Murphy and Ray Nenuskay includes an illustration of Adam Thompson in his first bathtub.

1935: Dr. Hans Zinsser, professor in the Medical School of Harvard University, says on page 285 of his best-selling Rats, Lice and History: “The first bathtub didn’t reach America, we believe, until about 1840.”

November 15, 1935: R.J. Scott’s “Scott’s Scrapbook,“ syndicated by the Central Press Asociation, includes a sketch of a policeman chasing a bather away from his bath, together with the caption: As late as 1842 some American cities prohibited the use of bathtubs.”

May 27, 1936: Dr. Shirley W. Wynne, former commissioner of health for New York City, uses the “facts” in a radio address, “What Is Public Health?“ over WEAF.

February, 1937: The United Press Red Letter includes a story from Cambridge, Massachusetts, that Dr. Cecil K. Drinker, dean and professor of physiology at the Harvard School of Public Health, has discovered that his great-great-grandmother, Elizabeth Drinker of Philadelphia, had a bathtub in her home as early as 1803, thus disputing Cincinnati’s claim to fame for having the first American bathtub. (The Chicago Daily News used the story March 27, 1937.)

September 28, 1938: Hearst’s American Weekly includes an article, “There’s a Lot of History Behind Your Bathtub,“ by Virginia S. Eiffert, research expert and contributor to Natural History, official magazine of the American Museum of Natural History, New York City, and other publications. Miss Eiffert’s research has uncovered the old stand-by.

Sept. 20, 1942: Julia Spiegelman retold the entire Adam Thompson tale as fact in an article, “Bathtub’s United States Centennial” in the Baltimore Sun, Mencken’s own newspaper.

April 28, 1951: In this day’s issue of The New Yorker John Hersey revealed, in a profile on Harry S. Truman, that “the president seemed reluctant to let go of his belief” in the fact that Millard Fillmore introduced the first bathtub into the White House in 1850. President Truman was known to include the spurious facts in the “lecture” he gave visitors to the renovated executive mansion.

Sept. 16, 1952: In a speech in Philadelphia, President Truman told the story to illustrate what great progress has occurred in public health.

I noted the Tucson Daily Star mention — I spent a year in Tucson at the University of Arizona, and on a couple of projects spent hours poring through old copies of the Star and it’s competitor, The Tucson Daily Citizen, but never getting close to any story on Fillmore, bathtubs, or Mencken.  Interesting.

And did you see?  There’s a reference to Zinsser’s great book, Rats, Lice and History.   One of my favorite books of all time. Other suggested it should be included in the small, essential library of any historian or teacher of history, when I was working on assembling a list of necessary books (a project I really should get back to one day).

Zinsser was the guy who isolated the pathogen that causes typhus, and developed a vaccine against the disease.  More importantly, he was a bit of a rake and an excellent, and funny, writer.  The book is a breezy read,  packed with enlightening discussions of history, wars, economic booms and busts, sieges of great cities, and how disease stalks the pages of history much more than merely during the outbreaks of the plague in the middle of the second millennium.

I read the book the year I graduated from high school, though now I don’t remember whether it was during the school year or after.  It was recommended to me by a college English professor, Kirk Rasmussen (the Utah guy), whose wife was my last high school debate coach.  Kirk laughed all the way through the book.  I borrowed his paperback copy and finished it off in a week or two.

You can learn a lot about ecology studying how a disease is spread.  A disease like typhus, which involves insect, louse, rodent and human carriers, exposes the links that, however improbable or preposterous, are necessary to keep a pathogen going.  Zinsser gives a great rundown of the history of rats, the history of fleas, the history of lice (which are not insects, if you wish to be carefully accurate, which you do, of course).

So his book is useful in literature classes.  It’s a good source of history.  Plus, it’s a good meta source for biologists and medical researchers.

In fact I have a copy here on this desk — I was trying to find a short excerpt that I could use in my world history classes, something to intrigue students and give them fodder for an exercise or project.

So, I looked at that listing, and thought I should check it out:

1935: Dr. Hans Zinsser, professor in the Medical School of Harvard University, says on page 285 of his best-selling Rats, Lice and History: “The first bathtub didn’t reach America, we believe, until about 1840.”

You can see this one coming, can’t you?

Rats, Lice and History has only 228 pages, in all three editions I have here at the house.

So of course I checked pages 185, 85, and 28.  Nothing.

Then I looked at the table of contents (there is no index), to see in what chapter such a comment might find a home.  Zinsser wrote in the U.S., was born in the U.S., so it wouldn’t be wholly out of his character to note some little item of public health at the White House.  But I’ll be doggoned if I can figure out where such a comment would fit in the book.

Is this just a miscitation by Museum of Hoaxes?  Or is it a new hoax altogether?  Is it a hoax the Museum of Hoaxes has fallen victim to, or is it of their invention?

Now I wonder about all the other mentions there.  Are they accurate?  Are they whole cloth fiction, voodoo history?  Did the Tucson Daily Star even exist in 1931?

We never solve one mystery that we don’t open up a dozen more.

Readers, can you shed light?

I’m sure there is a reasonable explanation.


I get e-mail from DDT cranks . . .

January 3, 2009

I noted the errors in a post at Reformed Musings.  Then I noodled around Mr. Mattes’s site,  and I dropped this note into his “about” thread, frustrated that I couldn’t just politely note the errors at his posts, where he’s disabled comments.

I said:

I wish you’d take comments on your posts. For example, you’ve got a couple of errors dealing with DDT in your post on climate change. It looks as though you’re hoping to sneak them past readers, rather than get the science right. I hope that’s not so.  By: Ed Darrell on December 31, 2008 at 7:41 pm

Mattes held that comment in moderation (afraid to let his other readers see it?), but responded in sort by diving deeper into wankery, with a post defending the more crackpot ideas of Michael Crichton, and straying much farther from the science in his claims about DDT and environmenta protection.  Heck, he even trotted out errors about Paul Ehrlich’s writing, apparently not content to be wrong about only DDT and global warming.

So, noting Mattes’s aggravation of his errors, I wrote again on his blog, a bit more sternly:

Shame on you. If you really think DDT is safe and that there was no science behind its “ban,” open comments, let us discuss.

But to compound your errors, and then to fail to approve comments from those who offer you correct information — well, reformation only goes so far, I guess.  By: Ed Darrell on January 2, 2009 at 11:56 am

Rather than open comments to discuss, and rather than respond to the post at the Bathtub, he sent me e-mail:

Shame on me? Excuse me, but I’m a bit amazed at your arrogance. You’ll offer correct information? Why, because others have a different opinion than you they have to be wrong? What are your technical qualifications and applicable experience, besides having a blog and a keyboard? Have you been to Africa? I have. Is racial eugenics your thing? Is that why third-world inhabitants are expendable to you?

Whatever you think you know, DDT is being successfully employed in Africa and elsewhere to save lives every day. No bad effects evident.  None. Their public health officials are literally begging for more. But then, their only agenda is survival. Selective and misleading reporting doesn’t interest them, only results.

Did Mattes miss many of the Tinfoil Hat Brigade’s concerns?

For the record, I don’t share Mattes’s fascination with eugenics as applied to race (and I’ll wager Mattes has no record fighting it); that tends to be a concern of the anti-science, historical revisionists (wrong about history, too).  I said nothing disparaging about third world peoples, and there are a dozen or more posts here to confirm my concerns about health in the third world, in contrast to only the junk science, “Let’s poison the hell out of Africa” attitude from Mattes.

In his second paragraph, he contradicts one of the main points of his first post. He says DDT is being used successfully in Africa — while his first post complained that environmentalists had successfully stopped it from being used.

That’s rather the mark of the true DDT sycophant, someone who suffers seriously from internet DDT poisoning:  The only reason they mention DDT is to find a cudgel to use against brave and smart women like Rachel Carson, or otherwise to criticize people who call for an end to pollution, or the preservation of water, air, trees or animals.  Unanchored by any fact or any need or desire to be accurate, they attack environmenalists, damn the inconsistency of the attacks.

Oy.

He’s followed up today with a new post that assaults science at every turn, claiming to follow science journals, but instead citing the chemical industry supporters like Richard Tren, opposing the Centers for Disease Control and World Health Organization.  While complaining about “eco-socialism,” he approvingly cites the experts of Lyndon Larouche, the late Dr. Gordon Edwards, in all of his errors and all of the political wankery of Larouche.

Mattes has gone back to the false claims that Edmund Sweeney exhonerated DDT, and that “evil” William Ruckelshaus banned DDT anyway — completely murdering Sweeney’s analysis and the law behind it, and completely avoiding the law, the court cases, and the history behind Ruckleshaus’s actions.

In his frantic, apoplectic dance to avoid discussing whether he might be in error, Mattes has dived so deeply into the depths of tinfoil hat sourcery (no, it’s spelled as I intended it) that in the end, he’s not jus twrong, he’s not even wrong.

If someone criticized any translation of the Bible as carelessly and wildly as Mattes criticizes science, he’d be out recruiting neighbors with pitchforks and torches to march.

Mattes claims he’s done with the issue.  We can only hope.  To continue in his current trend, he’d need to deny gravity (both Newton and Einstein), atomic theory, and Linneaus.  But I also suppose it means he’ll never check here to see the facts.  Just when we thought we were making progress . . .

DDT falsehoods, taken as an article of faith

December 31, 2008

Brown pelican egg rendered uncapable of protecting the (now dead) chick when DDT prevented the mother pelican from forming an adequate shell for the egg.

Brown pelican egg rendered uncapable of protecting the (now dead) chick when DDT prevented the mother pelican from forming an adequate shell for the egg. Pelican Media image.

Just when you start thinking the world is safe for the facts — safe for the truth — some well-meaning-but-poorly-informed person comes along to remind you that it’s a constant struggle to keep the flame of truth from being snuffed out for no good reason.

Henry I. Miller didn’t publish a screed demanding DDT be misused against West Nile virus this year, which I count as a major victory.  As you know, DDT is the wrong stuff to use to fight West Nile, so calling for DDT in that case merely means you’re an ideologue who wants to slam science, and it probably means you wish disease victims would hurry up and die.  (“More statistics to use against libruls!”)

Henry I. Miller. How many years at the Hoover Institute before he finds the library at Stanford to check his claims on DDT?

Henry I. Miller. How many years at the Hoover Institute before he finds the library at Stanford to check his claims on DDT?

And even Oklahoma’s reigning Senate fool Tom Coburn lifted his hold on the bill naming for Rachel Carson the post office in her hometown.

But, on the second to last day of the year, comes Bob Mattes at Reformed Musings, to claim that climate change is a hoax, and say he knows it’s so because DDT is safe and Rachel Carson was wrong. Mattes is a deacon in a Presbyterian church in Virginia; the name of his site is a reference to reformed theology, I gather.

When someone claims as a matter of faith, things that are well known to be wrong and easily debunked, that someone is unlikely to be swayed by the facts. In fact, Mattes allows no criticism of his post at his blog — he’s turned off comments on that post.

Will he drop by here to read his errors?  Not likely.  Would he correct the errors if he knew?  It’s not good to gamble when the odds are long against you.

Well, no, I don’t want an alleged example of eco-socialism from an eco-fascist, one whose mind is made up, incorrectly, and who will not let the facts sway him.  Notice that the authority he cites is that well-known purveyor of junk science, Junk Science, the ethically-challenged website run by the industry campaign in favor of DDT.  If one dances to the devil’s tune, one should not claim not to be doing the devil’s work.

If this be eco-socialism, it’s God-blessed, and we should revel in it and make the most of it.

In the 60’s, there was the big DDT scare, with activists claiming that the pesticide was killing off our birds and bees.

Right.  And it was true, DDT was killing our birds and bees.  It took more than 30 years of not using DDT to rescue our national symbol, the bald eagle, from DDT’s killer effects.  Is it fair to call it a “scare” if it’s true?

Rachel Carson sold the big lie in her famous book Silent Spring, which was full of misrepresentations.

See, here’s how we know Mattes doesn’t know what he’s talking about, and probably hasn’t read the book.  Carson was very careful in her book.  She offered more than 50 pages of citations to science papers and hard research to support what she wrote — a “don’t take my word for it, check it out for yourself” kind of honesty.

Discover magazine carried an article about DDT and Carson’s book in November 2007Discover said that, since 1962, more than 1,000 peer-reviewed publications support Carson’s conclusions, a record remarkable in any branch of science.

In fact, Carson may have underestimated the impact of DDT on birds, says Michael Fry, an avian toxicologist and director of the American Bird Conservancy’s pesticides and birds program. She was not aware that DDT—or rather its metabolite, DDE—causes eggshell thinning because the data were not published until the late 1960s and early 1970s. It was eggshell thinning that devastated fish-eating birds and birds of prey, says Fry, and this effect is well documented in a report (pdf) on DDT published in 2002 by the Department of Health and Human Services’ Agency for Toxic Substances and Disease Registry (ATSDR). The report, which cites over 1,000 references, also describes how DDT and its breakdown products accumulate in the tissues of animals high up on terrestrial and aquatic food chains—a process that induced reproductive and neurological defects in birds and fish.

Had Mattes been paying attention (was he even alive then?), he’d have noted that President John F. Kennedy tasked the President’s Science Advisory Council to check out Carson’s book, to see whether it was accurate, and whether the government should start down the path of careful study and careful regulation of pesticides as she suggested.  In May 1963 the PSAC reported back that Carson was dead right on every issue, except, maybe for one.  PSAC said Carson wasn’t alarmist enough, that immediate action against pesticides was justified, rather than waiting for later studies or delaying for any other reason.

So, here I issue a challenge to Bob Mattes:  Tell us where Rachel Carson was wrong.  Cite for us a page in Silent Spring where she made a significant error in science, a point that has not been borne out as correct in later studies.

I’ve been making this challenge for a year and half now, and not even Stephen Milloy has been able to offer a single error Carson made.  A few have said they “heard” Carson erred in one thing or another, but upon checking, we’ve always found that the claimed errors were nowhere to be found, or the errors alleged were misstated, or, more often, what was claimed as error simply was not.

It’s a very odd situation:  We have a deacon of the Presbyterians assaulting the honor of a distinguished scientist, using false claims as his ammunition.

As usual, the ignorant entertainment industry frothed at the mouth for the new fad cause. Joni Mitchell sang: “Hey, farmer, farmer, put away that DDT now. Give me spots on my apples but leave me the birds and the bees.” Cute, huh?

As a result, DDT was banned world-wide. Problem was, not only were the zealots wrong, but nothing killed deadly malaria-carrying mosquitoes better than DDT.

DDT has never been banned worldwide.  It’s still manufactured in several places — it’s still a deadly hazard in India.  It’s been in constant use in many nations, such as Mexico and South Africa.  Limitations on DDT use have always included a loophole allowing DDT to be used to protect against malaria — even the 2001 Persistant Organic Pesticides Treaty has a special clause allowing DDT to be used against malaria.

So it’s false to claim that DDT was banned worldwide, ever.  We might be much better to get to that position because it would keep nuts from claiming that all we have to do is poison Africa to make Aricans healthy — but in any case, there is no ban on DDT to fight malaria.

Use of DDT began to decline in the mid 1960s when mosquitoes began to exhibit resistance and even immunity to the stuff.  Genetic studies now find that almost all mosquitoes in the world have multiple copies of a gene that allows the bug to digest DDT more as a nutrient, rendering it ineffective as a pesticide.  The World Health Organization had begun an ambitious campaign to knock down mosquito populations long enough that malaria would die out; but by the mid 1960s, the burgeoning resistance to DDT rendered that campaign untenable.  DDT use against mosquitoes, which was never undertaken in much of Africa because some local governments were not stable enough to manage an anti-mosquito campaign, declined, and stopped in places where DDT simply did not work.

In fact it was gross overuse of DDT by agricultural interests that drove the resistance among insects.  Had that overuse been controlled earlier, we might have been able to kill of malaria.  It was not a ban on DDT that caused its use to decline.  It was that DDT stopped working.  No one in their right mind will spend money on a pesticide that doesn’t work, no matter how cheap the stuff is.

But it wasn’t popular culture that got DDT banned.  In the late 1960s litigation on DDT spraying worked through the courts.  By 1972, two federal courts ruled in separate cases that the federal government had failed to carry out its obligations to control the use of DDT as required by law, based on evidence presented in court that demonstrated clear harm.  Both courts ordered the government to promptly hold the administrative hearings necessary to alter the registration for DDT.  The hearings started in the Department of Agriculture, which moved slowly.  When the Environmental Protection Agency (EPA) was created, it got the authority to regulate pesticides from Ag.  The courts ordered EPA to get off its duff and speed the process.

In the midst of a nine-month-long hearing process that accumulated thousands of pages of scientific documentation of the harms of DDT, manufacturers of the pesticide voluntarily changed their labels to limit use of DDT essentially to emergency situations, not general broadcast applications. Judge Edmund Sweeney, the EPA administrative law judge, thought that change, which was what was pending, meant that EPA did not need to act, and he so ruled at the end of the process.  EPA Administrator William Ruckleshaus, a veteran of more recent environmental litigation, understood the courts had ordered a more ironclad change, and he imposed tighter registration standards on DDT that prohibited its use on agricultural crops, except in emergencies.  There was also a loophole built in to protect public health.

DDT manufacturers sued EPA to overturn the rule.  The courts ruled that the scientific evidence was overwhelming, and that EPA’s rule was firmly grounded.  The manufacturers did not appeal further.  So, DDT use in the U.S. was severely restricted by the end of 1972, following earlier restrictiosn in Sweden.

Can Mattes read a calendar?  How does a ban on DDT in Sweden in 1970, in the U.S. in 1972, make Africa stop using DDT in 1965?

Literally millions of poor have needlessly died from malaria in Third World countries as a result of the ban. Malaria is the 4th leading cause of death in the world. Drug-resistant strains are starting to dominate. Eradication is the real answer. Only recently have countries like South Africa defied the ban and started spraying DDT again to fight malaria. Ideas have consequences – eco-socialism routinely kills, just not in the comfy apartments of the self-serving eco-socialists.

What ban is he talking about? South Africa suspended DDT use only briefly at the end of the 20th century — but South Africa’s problems are not caused because South African mosquitoes roared back when they were not sprayed wholesale with DDT.  Malaria in South Africa rose when the disease came over the border from other nations where the disease was less controlled.  South Africa brought back DDT use, though in a more limited fashion.  There was no ban to defy.  Mattes is telling a whopper here.

Mattes cites the Centers for Disease Control when he says malaria is the fourth leading killer in the world.  He either fails to notice or fails to say that CDC does not ask for DDT to be brought back to fight malaria.  CDC calls for bednets, for draining of breeding areas, for better medical care and better diagnosis, but not for more DDT.  Why?  When the leading disease fighting organization in the world does not ask for DDT, we might assume it puts DDT way down on its list of priorities (as it does).  Remember, CDC’s origins were in the fight against mosquito-borne diseases.  CDC speaks with authority on mosquito eradication.  CDC does not ask for more DDT, anywhere.  His own authority — he should listen to them.

Health care professionals note that malaria made a serious resurgence when the malaria parasites themselves became resistant to the pharmaceuticals used to treat them.  This has nothing to do with DDT, because DDT is not given as a drug to humans (it’s a poison, mildly carcinogenic, and there is no demonstrated effectiveness against the parasite).

Can Bob Mattes read a map?  How do restrictions on spraying DDT on cotton fields in Texas, cause malaria to increase in Africa?

Mattes closes his post:

History shows that the eco-socialists have NEVER been right. EVERY scare prediction they’ve ever tried fails to materialize. Unfortunately, history starts today for most folks. We don’t teach logic or real science in public schools anymore, just the religion of political correctness. Ignorance breeds disaster, especially for those in developing countries who can’t speak for themselves and don’t have a George Soros funding their latest fad cause. Remember DDT. Remember global cooling. Remember the limitations of computer modeling. Don’t be duped.

Except, the “eco-socialists” as Mattes mislabels them were right about DDT, they were right about malaria, they were right on the science about wildlife damage from DDT, and they were right on the history.

Ignorance does indeed breed disaster, which is where Mattes’s views will take us.  He should carefully consider his closing trio of words, and follow them religiously.

If Mattes is so wrong on every claim about DDT, do you think we should trust anything he says about climate change?

Typewriter of the moment: Muckraker Upton Sinclair

December 17, 2008

Without typewriter, however.*

A journalist and novelist, labeled by President Theodore Roosevelt as a “muckraker,” Upton Sinclair. The caption to the Associated Press photo said it was Sinclair working on his first movie screenplay in 1943, part of his generally forgotten life in California. In fact, several of his works were made into movies.

* I had difficulty getting the images to work in this post.  Odd stuff kept popping up.  Then, as a reader Michael Todd gently noted, I discovered I’d used a picture of Sinclair Lewis in place of Upton Sinclair.

In working to correct the problem, I discovered no photos of Upton Sinclar with his typewriter.  So, here we have Upton Sinclair, without typewriter.  How embarrassing.


Beating malaria without DDT

November 3, 2008

I told you so.

Recent research and assessments of anti-malaria campaigns in Africa show dramatic results from the use of bed nets and other non-DDT spraying methods.

Rachel Carson was right.

I was compelled to jump into this issue when Utah’s U.S. Rep. Rob Bishop made a silly and incorrect statement against Rachel Carson, after his failed attempt to derail a bill to rename a post office in her honor on the 100th anniversary of her birth.  The slam-Rachel-Carson effort turned out to include Oklahama U.S. Sen. Tom Coburn (who has since recanted), and an array of anti-science types who rail against “environmentalists” and made astoundingly false claims against Carson’s work and Carson herself.

In those cases, Carson’s critics called for a return of massive spraying of DDT.  Eventually most of them backed off of calling for outdoor spraying.  Eventually Sen. Coburn lifted his hold on the post office renaming legislation (and it passed).

The calumny continued on the internet, however, with an active hoax campaign for DDT and against environmental protection and Rachel Carson.  Steven Milloy joined Lyndon Larouche in promoting the anti-Carson screeds of the late Dr. Gordon Edwards, a UC Davis entomologist who argued against science that DDT was harmless to humans and animals.

Enough about history.  Look at the real results on the ground, today:

First, note the study published in Lancet that documents a dramatic decrease in malaria in Gambia, using “low-cost” strategies that include bed netsAgence France Presse carried a summary of the study. [Another link to the same AFP article.]

Incidence of malaria in Gambia has plunged thanks to an array of low-cost strategies, offering the tempting vision of eliminating this disease in parts of Africa, a study published Friday by The Lancet said.

At four key monitoring sites in the small West African state, the number of malarial cases fell by between 50 percent and 82 percent between 2003 and 2007, its authors found.

The tally of deaths from malaria, recorded at two hospitals where there had been a total of 29 fatalities out of 232 admissions in 2003, fell by nine-tenths and 100 percent in 2007. A fall of 100 percent means that no deaths attributed to malaria occurred that year.

“A large proportion of the malaria burden has been alleviated in Africa,” the study concludes.

Also see:

Second, note that malaria rates also fell in Kenya, with a shift in infections away from young children, a very good sign. TropIKA.net carried a summary of that study.

Toronto’s Globe and Mail carried a longer story on Kenya’s experience, “Malaria a rare public-health success story in Africa.”

“We had to stay home and tend the sick – you can never leave them to go and work in the fields – and then there was no income and we were hungry. So truly, that 100 shillings was a great investment.”

The family heard about the importance of using a bed net to fend off malaria in a sermon at church, and then on the radio. Now, a year later, they would be able to get them for free, as Kenya ramps up its efforts to get every single citizen sleeping under a net.

Already, two-thirds of Kenyan children are sleeping beneath them and, as a result, child malaria deaths have fallen by 40 per cent in the past two years.

This remarkable success story has been repeated across much of Africa: Deaths of children under 5 declined 66 per cent in Rwanda from 2005 to 2007 and by 51 per cent in Ethiopia.

“This really is the one global public-health story that is simply and straightforwardly positive,” said Jon Lidén, spokesman for the Global Fund to Fight AIDS, Tuberculosis and Malaria, which has been behind much of the push.

“It’s not a gradual change. It’s a fundamental change in the fight against malaria.”

Yet the decidedly unglamorous innovations responsible for the change – spraying houses, treating standing water to kill larvae, mass distribution of cheap polyester nets and better drugs, and simple public education on the need to treat suspected malaria quickly – receive almost no attention.

“We never make the headlines with this stuff,” said Shanaaz Sharif, head of disease control for Kenya’s Ministry of Health, which has thus far given out 11 million nets at a cost to the government of $6 each.

Despite pledges from the U.S. to signficantly increase funding to fight malaria, money has not flowed from the U.S., especially for bed nets.  Ironically, Canada is the chief donor of the nets.

Canada has had a key role in this success: The Canadian International Development Agency is the single largest donor of bed nets to Africa – nearly 6.4 million by the end of last year. In addition to government support, Canadian individuals and charities – notably the Red Cross – have embraced the issue by making donations and fundraising.

“Canadians … haven’t got the credit they deserve,” said Prudence Smith, head of advocacy for Roll Back Malaria, a partnership between key global-health agencies and donors such as the Bill and Melinda Gates Foundation.

Not all news is good. In Zimbabwe, dictator Robert Mugabe misused $7.3 million in malaria-fighting money from the Global Fund to Fight AIDS, Tuberculosis and Malaria. So far, he has not repaid the Global Fund. Politics continues to kill Africans, not an absence of DDT.

In India, where DDT use is untallied, manufacture massive, and use virtually uncontrolled, malaria is resurgent. According to The Telegraph in Calcutta, malaria is epidemic among people living in poorer sections of the city, often with fatal results.  ExpressIndia.com’s headline tells the story:  “Malaria puts city on the edge:  toll rises to 8.”

Public health officials in India will step up information and education campaigns, and urge residents “not to panic.”

(Sex + Education) – Education = ?

June 25, 2008

From a blog called Teachers Count:

A middle-school health teacher (in a small, conservative [read that religious] community) was put on administrative leave for teaching details about sexuality. The original story inferred that she was holding forth on details on homosexuality, masturbation, and oral sex. The truth is that she had taught the regular curriculum and thereafter fielded student questions, which turned to these things.

On the one hand, the outraged and prolix parents had every right to wax eloquent, loud and long on the violation of their parental rights in teaching their offspring about sex. It is even possible that some of those innocent students were hearing details theretofore unimagined by them

On the other hand–probably not. I teach junior high students, the same age as the endangered middle school kids in question. My students know lots about sex, far more than I ever knew at that age. For sure, these students see very explicit material on prime-time TV, and they surely see plenty of sex in the movies they watch. From time to time we discuss cinema in art class, and I am often floored at the kinds of movies these young kids view, both for violence and for sexuality. Furthermore, they watch and rewatch very explicit music videos–and many of them use outright porn. And furthermore, walking around the art room as kids work and talk, I overhear that many of them are sexually active at thirteen, fourteen, fifteen.

No wonder they have questions about sexual practices. I believe the young health teacher caught herself in a trap. Experienced teachers know that there are certain things you never say, never discuss, because of community reaction. Young teachers, hoping to help kids understand a sexual world they really are much too young for, can get tripped up on answering questions.

No doubt our Utah middle school health teacher will not have her contract renewed next year. I think that is a shame. Obviously, the offended parents have no clue about what their kids’ lives are really like. They do not realize the misinformation–and the pressure–these young students experience. I would not be surprised to find that these offended parents have not given their kids much information on sex. Maybe the teacher crossed a line–and maybe a few students pushed her there. Still, I’d rather see her keep her job and learn the hard lesson of staying very conservative on certain subjects, like sex.

Accusations included the charge that the teacher distributed a list of 101 ways to have sex.  In a heated meeting at the school, it turned out that the list was of 101 things to do instead of having sex.  Ooops.  And for this, parents want the woman fired?

Good analysis and background data in column by in the Salt Lake Tribune.

From that column, a list of what can and cannot be taught:


Careful what you say

What teachers can, and cannot, teach
as part of Utah’s human sexuality curriculum:
Teachers can:
* Stress the importance of abstinence from sexual activity before marriage and fidelity after marriage.
* Provide factual, unbiased information about contraception and condoms with prior written parental consent.
They cannot:
* Discuss the intricacies of intercourse, sexual stimulation or erotic behavior.
* Advocate homosexuality.
* Advocate or encourage contraceptive methods or devices.
* Advocate sexual activity outside of marriage.

Meanwhile, back at the DDT manufacturing plant . . .

June 9, 2008

Don’t breathe the air, don’t eat the eggs.  Life next door to a DDT plant in India.

In case you were wondering where nations that want to use DDT might find some, now that it’s not being made in the U.S.
