Cecil Adams’ forum honors Darwin!

February 12, 2009

Interesting compilation:   In honor of Darwin’s 200th anniversary, take Steve Bratteng’s 13 questions evolution answers that intellligent design cannot; add to that some almost-recent polling data on creationism among Republicans, and kick off a discussion.

Someone posting at the Cecil Adams’ site, Straight Dope, did just that.  Go join the discussion.

Trying to flatter me, of course, they linked to this blog — but  it’s all Steve Bratteng’s work.

His questionnaire deserves a much broader audience.  So, Welcome Straight Dopers.

Update:  Goin’ viral now — A forum at Free Republic picked up on the quiz, too (from Straight Dope?).  Go check out the discussion there — lots of concern that the malaria question is answered by the existence of Rachel Carson, which means those who propose that don’t understand evolution and haven’t read Rachel Carson, either.  Welcome, Freepers.


DDT ain’t pixie dust; we can’t poison Africa to health

February 7, 2009

Internet communications spreads information far and wide, but it also spreads disinformation and error far and wide — sometimes faster than good information.

Bill Gates gave a TED* Talk about the need to fight malaria, and where his billions-of-dollars campaign against the disease is going.  Within minutes, the nattering nabobs science ignorance were calling Gates an idiot, and calling for the poisoning of Africa.

Gates, you may remember, is either the richest man in the world or close to it due to his brilliant marketing of Microsoft products.  This would suggest to rational people that he is not an idiot, at a minimum, and perhaps should be listened to on topics which he has researched, such as malaria and mosquitoes.   Africa, you may remember, has a lot of people in it who don’t want to be poisoned, thank you very much. This may suggest that DDT would be controversial even were it a panacea, which it is not.

Rational voices exist.  Deltoid and Bug Girl both provided useful, and accurate information (though in this case, Tim Lambert at Deltoid refers to the DDT controversy on bed bugs, and to another Bug Girl post on research showing DDT won’t help against bed bugs).

Here’s the controversial two minutes of Gates’s talk (you can see it at Bug Girl, too):

Internet and other media now fall into a predictable rhythm:  Any news faintly related to DDT prompts stiff-necked conservatives and other do-nothings who don’t like environmentalists to write stuff calling for a “return” of DDT, making erroneous claims that DDT had made the world safe against malaria, and that only the delusional claims of Rachel Carson convinced everyone to stupidly stop spraying DDT.  And, of course, they then make the erroneous claim that all we need to do to fix everything is bring back DDT.

They don’t ever let the facts get in the way of a stupid, misplaced political hit.

In short, they treat DDT as pixie dust, a magic solution to every problem.  This is fantasy.  In reality, we cannot poison Africa to good health.

I’ve written about these issues before at length.  Hard research, good research, tells us what we have to do to fight malaria

  • Money must be spent to improve health care in Africa, especially to remote populations. Wiping out malaria requires that we get rid of the parasite in humans.  Mosquitoes get the parasite from infected humans, after all — if mosquitoes can’t get infected from humans, we don’t need to worry so much about killing the mosquitoes.  Preventing infections is good; curing those that exist is essential.  Malaria parasites’ ability to grow resistance to pharmaceuticals means we need health care delivery systems that will assure a complete cycle of medical treatment occurs in every victim, and before that, that a quick and accurate diagnosis will allow targeting of the right drug to the specific parasite.
  • Housing improvements will provide huge benefits. Malaria was wiped out in the U.S. and Europe partly by rising incomes.  Even poor people could afford screens on windows, which keeps mosquitoes out of the house, where most infections start.  Housing unsuitable to screening will put a larger burden on bednets.  But better housing is a key part of the fight.
  • Improving incomes help fight malaria. Families with more money can afford better housing, and better health care.  Malaria, and most disease, is very much an “Are Your Lights On” sort of problem.  Victims are the first to know they need to get medical care, and they are in the best position to prevent infections earlier.  If potential victims have the money to buy the tools to fight malaria, malaria has a tough time.
  • Good public works, from local governments, help fight malaria. Good roads work well to fight the disease.  Bad roads develop potholes.  In Africa, potholes fill with water and become breeding sites for mosquitoes.  Well-engineered, well-maintained roads and walkways make great contributions to eliminating malaria.
  • Education on how to avoid malaria pays huge dividends. People who know how to look for mosquito breeding places, and how to eliminate them, are crucial to the elimination of the disease.  Abandoned tires are classic mosquito breeding dumps, but so are rain gutters and even badly-drained flower pots.  When these things occur close to homes, mosquitoes breed there and bite victims close to home.  Since most people spend a signficant amount of time at or near their homes, eliminating these infection opportunities pays off well.  Further, certain breeds of mosquitoes are active at particular hours of the day or night.  Avoiding the places these breeds exist at the hours of their activity prevents malaria infection.  People must be educated to know these things, and to act on them.
  • Bednets work well, and bednets do not prevent the use of other methods. Pitting a fight against bednets and DDT is a favored tactic of pro-DDT groups.  Research shows bednets are very effective without DDT, but that DDT is not effective over the long term without bednets.  A mild solution of DDT applied to bednets in some areas improves the efficiency of the nets.  This is not an one-or-the-other issue.  Bednets always work, insecticides can be used appropriately.  To beat malaria, we will have to use every tool.  Bednets are a great tool, and they will be required regardless the availability or propriety of DDT.

The Bill and Melinda Gates Foundation stepped in to provide money and organization to the fight against malaria a few years ago.  In the last year alone his work and his money have helped prevent millions of cases of malaria, reducing the incidence of the disease by 50 percent in some areas, and 85 percent in others.  Whatever he says about malaria and mosquitoes deserves a good listen at least.

Suicide attempt with DDT

January 31, 2009

DDT advocates argue that DDT is harmless to humans.  Generally they base the claim on DDT’s low carcinogenicity in humans — it’s suspected of being a weak human carcinogen.

Frequently DDT advocates will point to the late Dr. Gordon Edwards’ grandstand sipping of a teaspoon of prepared DDT before lectures on the stuff.

Hard reality:  It’s a poison.  Comes this report from the Times of India:  A despondent woman tried suicide by DDT.  DDT is indeed a poison for humans.

The woman is in serious condition in a hospital.

AMRELI: The spate of suicides in the diamond industry continued as the wife of a diamond worker attempted suicide on Wednesday in Mini Kasbavad area of the city. Ruksana Pathan, 33, is battling for life at the government hospital here.

According to officials of Amreli police, Ruksana tried to end her life by consuming DDT powder when her husband and four children were away. She was rushed to the hospital here, where her condition is slated to be serious.

“Ruksana was depressed ever since her husband Taufiq Pathan, a diamond worker, was rendered unemployed after closure of diamond units,” said a police official. “As the family’s financial situation worsened, Ruksana attempted to kill herself,” the official said.

Kids, don’t try the Gordon Edwards stunt.  DDT is poisonous, as the skull and crossbones on the old label would indicate.


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.

DDT falsehoods, taken as an article of faith

December 31, 2008

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.

Reformed Musings said:

Want a concrete example of the impact of eco-socialism? Three letters – DDT.

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?

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.”

Solid research on controlling malaria

October 20, 2008

Looking for other things, I stumbled into two research journal articles on the fight against malaria.  Neither calls for a return to broadcast spraying of DDT; neither claims the ban on agricultural use of DDT had any significant effect on the rise of malaria.

Both are loaded with serious research that exposes DDT advocates as charlatans.

First:  from Clinical Microbiology Reviews, October 2002, p. 564-594, Vol. 15, No. 4
0893-8512/02/$04.00+0; DOI: 10.1128/CMR.15.4.564-594.2002. “Evolutionary and Historical Aspects of the Burden of Malaria,” by Richard Carter and Kamini N. Mendis:

SUMMARY:  Malaria is among the oldest of diseases. In one form or another, it has infected and affected our ancestors since long before the origin of the human line. During our recent evolution, its influence has probably been greater than that of any other infectious agent. Here we attempt to trace the forms and impacts of malaria from a distant past through historical times to the present. In the last sections, we review the current burdens of malaria across the world and discuss present-day approaches to its management. Only by following, or attempting to follow, malaria throughout its evolution and history can we understand its character and so be better prepared for our future management of this ancient ill.

Second, from Joel G. Bremen, Martin S. Alilio, and Anne Mills, “Conquering the Intolerable Burden of Malaria:  What’s New, What’s Needed:  A Summary,” Am. J. Trop. Med. Hyg., 71(2 suppl), 2004, pp. 1-15 (The American Journal of Tropical Medicine and Hygeine).

High school kids, there are the sources you need for your papers on the fight against malaria.


Atomic history, nuclear future

October 19, 2008

We’re going to see more nuclear power plants in the U.S., it’s a safe bet.  Both presidential candidates support developing alternatives to oil and coal.  Nuclear power is one of the alternatives.

John McCain kept repeating his comfort words, that ‘storage of wastes is not a problem.’ There is not a lot of evidence to support his claims.  With turmoil in financial markets, however, the nuclear power issue has gotten very little serious attention or scrutiny.  From the push to get compensation for radiation victims of atomic weapons and development in the U.S., I learned that the issue is not really whether wastes and other materials can be safely used and wastes stored. The issues are entirely issues of will.

Advantage to Obama, I think.  He’s not claiming that the storage problems are all solved.  A clear recognition of reality is good to have in a president.

Son Kenny sent a link to a history site, Damn Interesting, and it tells the story of the Techa River in the old Soviet Union — a place condemned for generations by the nuclear excesses of the past.

To make the story briefer, in their rush to produce nuclear weapons, the Soviets did nothing to protect Russia from radioactive waste products until it was much too late.  Efforts to reduce radioactive emissions, by storing them in huge underwater containers, resulted in massive explosions that released more radiation than Chernobyl (What?  You hadn’t heard of that, either?).

It’s a reminder that safety and security with peaceful uses of nuclear power depend on humans doing their part, and thinking through the problems before they arise.

Can we deal with radioactive wastes?  We probably have the technology.  Do we have the will? Ask yourself:  How many years has the U.S. studied Yuccan Mountain to make a case to convince Nevadans to handle the waste?  How many more decades will it take?

How is our history of dealing with nuclear contamination issues?  Not good.

Last spring SMU’s history department sponsored a colloquium on a power generation in the southwest, specifically with regard to coal and uranium mining on the Navajo Reservation.   We’ve been there before.

One of the photos used in one of the lectures, by Colleen O’Neill of Utah State, showed two Navajo miners outside a uranium mine during a previous uranium boom.  Neither one had a lick of protective equipment.  Underground uranium mining exposes miners to heave concentrations of radon gas, and if a miner is unprotected by breathing filters at least, there is a nearly 100% chance the miner will get fatal lung cancers.

Of the 150 Navajo uranium miners who worked at the uranium mine in Shiprock, New Mexico until 1970, 133 died of lung cancer or various forms of fibrosis by 1980 ([Ali, 2003] ).

Our Senate hearings on radiation compensation, in the 1970s, produced dozens of pages of testimony that Atomic Energy Commission officials understood the dangers, but did nothing to protect Navajo miners (or other miners, either).  It is unlikely that anyone depicted in those photos is alive today.

"Mine memory - Navajo miners work the Kerr-McGee uranium mine, 7 May 1953. Today, uranium from unremediated abandoned mines contaminates nearby water supplies. image: AP Photo" (borrowed from ehponline.org) This photo is very close to the one used by Prof. O'Neill. It may have been taken at nearly the same time. If you know of any survivors from this photo, please advise.

At a refining facility on the Navajo Reservation, highly radioactive wastewater was stored behind an inadequate earthen dam.  The dam broke, and the wastes flowed through a town and into local rivers.  Contamination was extensive.

Attempts to collect for the injuries to Navajo miners and their families were thrown out of court in 1980, on the grounds that the injuries were covered under workers compensation rules (where injury compensation was also denied, generally).

Navajos organized to protest the power plant. One wonders whether they can win it.

Sen. McCain seems cock sure that radioactive wastes won’t kill thousands of Americans in the future as they have in the past.  The uranium mining and uranium tailings issues occurred in Arizona, the state McCain represents.  Does he know?

We regard ourselves in the U.S. as generally morally superior to “those godless communists.”  Can we demonstrate moral superiority with regard to development of peacetime nuclear power, taking rational steps to protect citizens and others, and rationally, quickly and fairly compensating anyone who is injured?

That hasn’t happened yet.

When [uranium] mining [on the Navajo Reservation] ceased in the late 1970’s, mining companies walked away from the mines without sealing the tunnel openings, filling the gaping pits, sometimes hundreds of feet deep, or removing the piles of radioactive uranium ore and mine waste. Over 1,000 of these unsealed tunnels, unsealed pits and radioactive waste piles still remain on the Navajo reservation today, with Navajo families living within a hundred feet of the mine sites. The Navajo graze their livestock here, and have used radioactive mine tailings to build their homes. Navajo children play in the mines, and uranium mine tailings have turned up in school playgrounds (103rd Congress, 1994 ).

Think of the story of Techa River as a warning.

Malaria/DDT Carnival addendum

October 11, 2008

It’s almost as interesting that these posts show up on the same day, as what they say.

Following on the heels of the impromptu Malaria/DDT carnival earlier in the week, take a look at these posts:


Carnival of Fighting Malaria (and DDT)

October 8, 2008

It’s been about a year since the first, completely impromptu Carnival of DDT.  Last fall, in October and November, there was enough going on about DDT to merit something like a blog carnival, with a second in November.

My news searches today turned up a number of items of interest in DDT and fighting malaria — enough to merit another summary post, IMHO.  Here goes.

First, Tim Lambert at Deltoid sets straight the history of the policy of the World Health Organization (WHO) with regard to DDT use, and whether WHO caved in to pressures from environmentalists to completely ban DDT, as Roger Bate had earlier, erroneously said.  Tim has a number of well-researched, well-reasoned posts on DDT and health; people researching the issue should be sure to visit the archives of his blog.  But for today, make sure you read “Roger Bates’ false history.

This Friday the Hawk Mountain Sanctuary presents an award to Tom Cade, the Boise, Idaho guy credited with doing much to save the endangered peregrine falcon. You can read about it in the Allentown, Pennsylvania, Morning Call.

Cade played a major role in reviving the nearly extinct peregrine falcon in the 1970s. As a graduate student, he studied how a pesticide contributed to their sharp population decline. He eventually founded a conservation group, The Peregrine Fund, which reintroduced captivity-bred birds to the wild.

. . . The falcon’s revival is widely considered one of the most successful recoveries of an endangered species. The species teetered on the brink of extinction in 1970, when as few as 39 known pairs of nesting falcons existed. A 2003 survey puts the number of nesting pairs at more than 3,100.

On Thursday Cade will receive the Sarkis Acopian Award for Distinguished Achievement in Raptor Conservation.  According to The Morning Call, “The award is given infrequently by Hawk Mountain officials and is named after the Kempton-area bird sanctuary’s primary benefactor, a late philanthropist who studied engineering at Lafayette College.”

Also, see this story about the recovery of peregrines in Canada, from the Sudbury Star.

Bug Girl tells the story of a new documentary on the Michigan State University professor who documented the deaths of songbirds made famous in Rachel Carson’s book, Silent Spring. Dr. George J. Wallace’s work became the subject of an article in Environmental Journalism in 2005.  Students and faculty at MSU’s Knight Center for Environmental Journalism produced the movie, “Dying to Be Heard.”  Be sure to check out the comments at Bug Girl, for more information.

International health care expert César Chelala argues that the “War Against Malaria Can Be Won, Without DDT” at the on-line Epoch Times. Chelala reports on a project in Mexico — where DDT use has never stopped since 1946 — a project now extended to other places in Central America, demonstrating that the tried and true methods of preventing mosquitoes from breeding and avoiding contact work well to fight malaria.  Plus, he says, it’s cheaper than using DDT.  Doubt that it could work?  Chelala points out that the Panama Canal could not be dug without controlling mosquito-borne illnesses, and the Canal was opened in 1914, 25 years before DDT was demonstrated to be deadly to insects, more than 30 years before widespread deployment of DDT.

Early detection and treatment is critical to eliminate the parasite carriers. An important aspect of this project has been the collaboration of voluntary community health workers who are taught to make an early diagnosis in situ and to administer complete courses of treatment not only to those affected but also to the patients’ immediate contacts.

The project was carried out in specific pilot areas called “demonstration areas” which had been selected due to their high levels of malaria transmission. In those areas, the number of malaria cases fell 63% from 2004 to 2007. In several demonstration areas I visited in Honduras and Mexico as a consultant for the Pan American Health Organization malaria had practically been eliminated. Plans are underway to expand the project to other regions where malaria remains a serious threat.

One of the advantages of not using DDT (besides avoiding its toxic effects) is the enormous savings realized from discontinuing its routine use. These savings can now be put to good use with other diseases.

You might also want to view Chelala’s description of solutions for public health crises in Africa, at The Globalist.

Chelala’s cool, clear and accurate reporting sadly contrasts with the hysteric and wrong reporting at Newsbusters and other polemical outlets on the web, seemingly bent on perpetration of the hoax that DDT is harmless and Rachel Carson was wrong.

Liz Rothchild’s one-woman play about Rachel Carson, “Another Kind of Silence,” got good reviews upon opening at the Warehouse Theatre, in Croydon, England.

Meanwhile, from Uganda comes news that DDT spraying failed to reduce malaria in spraying done in that nation. Proponents expected a sharp and steep decline in malaria, but numbers are not greatly reduced.  Even after taking account for the legal difficulties of spraying, after conservative businessmen sought an injunction to stop DDT use, the results do not speak well for DDT’s effectiveness.

Contrary to expectations, data collected by health departments in Apac and Oyam districts, which record the highest malaria incidence in the world, do not reflect significant improvements since DDT spraying ended prematurely. From May to July 2008, which is the period immediately following the spraying, between 400 and 600 clinical malaria cases per 100,000 of the population were reported per week in Oyam; and 600 to 800 such cases in Apac for the same period. These are almost exactly the same as the number of cases reported between January and April 2008.

Getting news out of Africa is not always easy.  Reading reports from Ugandan papers, it becomes clear that reporting standards differ greatly from the U.S. to Uganda.  Still, the saga from Uganda demonstrates that DDT is no panacea.  Uganda is a nation that had not used DDT extensively prior to the mid-1960s.  Resistance to use now comes from tobacco and cotton interests who speciously claim that potential DDT contamination of crops would result in the European Union banning vital Ugandan exports.  The legal issues all alone assume Shakespearean tragedy dimensions.  Or, perhaps more accurately, we could call the story Kafkaesque.

Happily, we have evidence that younger people show concern about DDT pollution, in a story about the stuff in Teen Ink magazine.

A study in the UK finds DDT present in colostrum, the vital pre-milk substance newly-lactating mothers create for their babies, as well as in later breast milk.

Bed bugs continue their own surge on Americans, and knee-jerk writers editorialize for the return of DDT, completely unaware that bed bugs are among those critters most resistant to DDT, and unaware that there are other, more effective solutions.

James McWilliams writes in The Texas Observer that most of us are ecological illiterates, which makes control of pollution more difficult, in a review of a new book, The Gulf Stream. Canny readers will recognize McWilliams as the author of the recently-published book, American Pests: Our Losing War on Insects from Colonial Times to DDT.

Sandra Steingraber will lecture on November 11 in Philadelphia on “The Many Faces of DDT,” part of a series of lectures sponsored by the Chemical Heritage Foundation, “Molecules That Matter.”  Steingraber is the author of Living Downstream:  An ecologist looks at cancer and the environment.

Canada’s Leader-Post reports that Chinese food processors have been caught using DDT in food to reduce insect infestations.  The cycle starts all over again.

Time for this carnival’s midway to shut down for the night.  Don’t let the bed bugs bite.


DDT results disappointing in Uganda

October 3, 2008

October 2008 — Uganda is nearing the end of the season when the national health service sprays DDT inside homes to discourage mosquitoes from biting, and spreading malaria.  Results from DDT use this year show no improvement over the previous year, and in some cases malaria rates are higher.

The story from The Observer in Kampala, via All-Africa.com news, provides some of the details, but little analysis to be debated.  Is the failure of the program due to partial implementation, since implementation was resisted by businesses and cotton farmers?  Or is DDT simply ineffective?  It’s nearly impossible to tell from data available so far.

Below the fold, the story in its entirety.

A day in the life of a teacher: One more life saved

Kudos to Coach Russ Henrie in Delta, Utah (one of my mother’s home towns), for knowing CPR, and delivering it at a crucial time.


Why science matters in the campaign

September 7, 2008

Dr. Art Hunt at The RNA Underworld explains why Obama’s plan to double NIH research funding is a good idea.

Big bang for the buck:  Hunt’s analysis suggests doubling the research budgets might drive as much as a trillion dollar increase in our economy. Sure it’s optimistic — but read what he says.  And then consider:  Which platform offers the greatest hope of cures or treatments for cancers?  Which platform offers the best hope for a cure or treatments for Alzheimer’s disease?

The two industries I mention here – pharma and biotech – are intimately interwoven with the basic biomedical research enterprise, and a significant amount of the innovation that drives these industries originates (or originated) in the NIH-funded biomedical research laboratory. In this respect, the NIH budget is an investment, and a wildly-successful one. Even if we don’t take the face-value numbers I have pulled from Wiki here (that show an annual return of some 1000%, and more than 750,000 high-paying jobs the tax receipts from which would probably pay much of the NIH tab by themselves), and instead factor in that some of these receipts and jobs are not American, it is still easy to see that basic biomedical research returns considerably more than the investment made by the government. (And this doesn’t begin to weigh the intangibles, the ways that the research enterprise gives back to society as a whole.)

Science bloggers have been not so noisy as this issue might need:  The closest John McCain came to supporting science, the driver of our economy, was when he offered to assault education, and that’s the opposite of supporting science. Obama’s mentions are encouraging, but not frequent enough nor strident enough.

Think of just three of the issues that are affected by basic science research, that will be yelled about during the campaign:

The silence on science should make us very, very concerned.

Have you read Obama’s response to the 14 big questions on science policy?  McCain has not answered.

McCain picked the wrong woman

September 3, 2008

We need judgment and wisdom in a vice president of the U.S., as well as in a president.

Judging from this open letter to Gov. Sarah Palin, Sen. John McCain picked the wrong woman.

So we do get to talk about your policies. And we do get to talk about hypocrisy. You asked us to repect your family’s privacy, but you won’t respect my family’s privacy to make our own decisions!

“Our beautiful daughter Bristol came to us with news that, as parents, we knew would make her grow up faster than we had ever planned,” said Palin, 44, and her husband. “We’re proud of Bristol’s decision to have her baby and even prouder to become grandparents.” They asked the media to respect their child’s privacy.

How come she gets to make a decision but the rest of the girls and women in America don’t! You won’t even let me learn in school about all the decisions I might need to make!

McCain could have used a woman like FrecklesCassie. Alas for McCain, she’s about 20 years too young.

Maybe he should have waited. At a minimum, he should have shopped around for someone with more common sense.
