Map from The Lancet, accompanying article: "Malaria is caused by five species of a parasite that can be carried from human to human by mosquitoes. Over the last 150 years, the portion of the world where malaria is still endemic has shrunk, but the disease is still endemic in 99 countries. However 32 of these countries, most of them on the edges of the endemic zone, are attempting to eradicate the disease, while the rest are trying to reduce infections and deaths though control measures."


Quote of the moment: 1971, U.S. Court of Appeals for the District of Columbia orders a review of the safety of DDT

November 23, 2010

Excerpted from ENVIRONMENTAL DEFENSE FUND, INCORPORATED et al., Petitioners, v. William D. RUCKELSHAUS, Administrator of the Environmental Protection Agency & Environmental Protection Agency, Respondents, Izaak Walton League of America, Montrose Chemical Corporation of California, State of New York, Intervenors, 439 F.2d 584 (1971); Chief Judge David L. Bazelon wrote the decision.

This is a petition for review of an order of the Secretary of Agriculture,1 refusing to suspend the federal registration of the pesticide DDT or to commence the formal administrative procedures that could terminate that registration.

Born in Wisconsin, David L. Bazelon grew up in Chicago and practiced law there. In 1949, President Truman named him to the United States Court of Appeals for the District of Columbia Circuit, often described as the country's most influential court, next to the Supreme Court. At 40, he was the youngest judge ever appointed to that court. From 1962-1978 he served as chief judge, retiring in 1986 as a senior judge.

*      *      *      *      *

We conclude that the order was based on an incorrect interpretation of the controlling statute, and accordingly remand the case for further proceedings.  In this case the Secretary has made a number of findings with respect to DDT. On the basis of the available scientific evidence he has concluded that (1) DDT in large doses has produced cancer in test animals and various injuries in man, but in small doses its effect on man is unknown; (2) DDT is toxic to certain birds, bees, and fish, but there is no evidence of harm to the vast majority of species of nontarget organisms; (3) DDT has important beneficial uses in connection with disease control and protection of various crops. These and other findings led the Secretary to conclude ‘that the use of DDT should continue to be reduced in an orderly, practicable manner which will not deprive mankind of uses which are essential to the public health and welfare. To this end there should be continuation of the comprehensive study of essentiality of particular uses and evaluations of potential substitutes.’38

There is no reason, however, for that study to be conducted outside the procedures provided by statute. The Secretary may, of course, conduct a reasonable preliminary investigation before taking action under the statute. Indeed, the statute expressly authorizes him to consult a scientific advisory committee, apart from the committee that may be appointed after the issuance of a cancellation notice.39 But when, as in this case, he reaches the conclusion that there is a substantial question about the safety of a registered item, he is obliged to initiate the statutory procedure that results in referring the matter first to a scientific advisory committee and then to a public hearing. We recognize, of course, that one important function of that procedure is to afford the registrant an opportunity to challenge the initial decision of the Secretary. But the hearing, in particular, serves other functions as well. Public hearings bring the public into the decision-making process, and create a record that facilitates judicial review.40 If hearings are held only after the Secretary is convinced beyond a doubt that cancellation is necessary, then they will be held too seldom and too late in the process to serve either of those functions effectively.

The Secretary’s statement in this case makes it plain that he found a substantial question concerning the safety of DDT, which in his view warranted further study. Since we have concluded that that is the standard for the issuance of cancellation notices under the FIFRA, the case must be remanded to the Secretary with instructions to issue notices with respect to the remaining uses of DDT, and thereby commence the administrative process.

*        *        *        *        *

We stand on the threshold of a new era in the history of the long and fruitful collaboration of administrative agencies and reviewing courts. For many years, courts have treated administrative policy decisions with great deference, confining judicial attention primarily to matters of procedure.48 On matters of substance, the courts regularly upheld agency action, with a nod in the direction of the ‘substantial evidence’ test,49 and a bow to the mysteries of administrative expertise.50 Courts occasionally asserted, but less often exercised, the power to set aside agency action on the ground that an impermissible factor had entered into the decision, or a crucial factor had not been considered. Gradually, however, that power has come into more frequent use, and with it, the requirement that administrators articulate the factors on which they base their decisions.51

Strict adherence to that requirement is especially important now that the character of administrative litigation is changing. As a result of expanding doctrines of standing and reviewability,52 and new statutory causes of action,53 courts are increasingly asked to review administrative action that touches on fundamental personal interests in life, health, and liberty. These interests have always had a special claim to judicial protection, in comparison with the economic interests at stake in a ratemaking or licensing proceeding.

To protect these interests from administrative arbitrariness, it is necessary, but not sufficient, to insist on strict judicial scrutiny of administrative action. For judicial review alone can correct only the most egregious abuses. Judicial review must operate to ensure that the administrative process itself will confine and control the exercise of discretion.54 Courts should require administrative officers to articulate the standards and principles that govern their discretionary decisions in as much detail as possible.55 Rules and regulations should be freely formulated by administrators, and revised when necessary.56 Discretionary decisions should more often be supported with findings of fact and reasoned opinions.57 When administrators provide a framework for principled decision-making, the result will be to diminish the importance of judicial review by enhancing the integrity of the administrative process, and to improve the quality of judicial review in those cases where judicial review is sought.

Remanded for further proceedings consistent with this opinion.

(President Nixon’s Secretary of Agriculture Clifford M. Hardin reviewed DDT regulations and decided no further action was required — since 1958, USDA had been reducing and eliminating DDT from use on USDA lands, as was the Department of the Interior.  Environmental Defense Fund sued, arguing more action should have been required.  In a complex decision, the U.S. Court of Appeals for the District of Columbia ordered more study of the issue.  By the time of the decision, the Environmental Protection Agency (EPA) had been established, and EPA Director William D. Ruckelshaus took Hardin’s place as defendant, with EPA assuming USDA’s position as defendant agency.  EPA’s review resulted in a ban on use of DDT on crops in the U.S.)

Some historians and many critics of EPA’s decision to ban DDT from agricultural use in the U.S. fail to acknowledge the importance of this ruling.  Judge Bazelon said that great caution alone is not sufficient on the part of administrators, and he ordered that the evidence against DDT be placed on the public record for public scrutiny.  “Public scrutiny” in this case would mean analysis by scientists, pesticide manufacturers, farming and farm support organizations, health workers, policy makers, and reporters.

On one hand, this decision tends to favor DDT advocates.  Judge Bazelon said the administrator in charge of carrying out FIFRA, the Federal Insecticide, Fungicide and Rodenticide Act, must give advocates of DDT the basis for the ruling: “On the basis of the available scientific evidence he has concluded that (1) DDT in large doses has produced cancer in test animals and various injuries in man, but in small doses its effect on man is unknown; (2) DDT is toxic to certain birds, bees, and fish, but there is no evidence of harm to the vast majority of species of nontarget organisms; (3) DDT has important beneficial uses in connection with disease control and protection of various crops.”

On the other hand, Bazelon’s order means that the significant harms of DDT must  be spelled out in public — so that the administrator’s ruling can be contested if it does not do what FIFRA requires.  In other places in the decision, Judge Bazelon notes that Congress had required, through FIFRA, that a pesticide determined to be uncontrollably dangerous must be taken off the market, under the justification that it was “mislabeled.”  Lower courts had already made that determination on DDT.  Bazelon’s order set the stage to require the administrator to ban DDT as a matter of law — the administrator being  the Secretary of Agriculture originally, or the Director of EPA under the reorganization of the government that created EPA .

Critics of William Ruckelshaus’s decision to ban DDT miss this point of the law.  Under the findings of the nearly year-long hearing in EPA’s administrative law courts, DDT was found to be an uncontrollable poison in the wild.  FIFRA required such a pesticide to have its registration cancelled, with very little wiggle room to make a case for any continued use of the stuff.  Ruckelshaus’s action stopped the immediate shutdown of DDT manufacturing in the U.S.   This proved to be a mixed benefit decision.  While the U.S. benefited financially from export of DDT, that the U.S. exported a chemical banned for most uses inside the U.S. proved to be a sore point in foreign relations with other nations; also most of the manufacturing sites were highly contaminated, so much so that the manufacturers declared bankruptcy rather than stick around to clean them up under the rules of the Superfund which took effect in 1984.  Taxpayer dollars now pay for massive cleanup operations of DDT manufacturing sites in California, Michigan, and Alabama, and other places.


Delingpole: Wrong and bitter on DDT

November 21, 2010

The Daily Telegraph’s James Delingpole got suckered by the anti-Rachel Carson propaganda, and wrote a bitter piece complaining about how environmentalists are ruining the environment and people’s lives (double whammy:  environmentalists worry about people over profits, and the environment over corporations, so Delingpole hoped to tweak ’em at both ends).  Lots of discussion, too much to read and most of it nasty and off target.

It was a smaller part of Delingpole’s generally anti-science, contrary-to-fact rant about global warming.

Chris Goodall fixed all of Delingpole’s errors on DDT at Carbon Commentary.

Being pro-DDT has become as religious an exercise as being for creationism taught in public schools.  There’s no good evidence to support the point, but there are a tiny handful of people who are gullible enough to spread whatever they say.  That tiny handful of advocates never gets the facts on their side, nor they on the side of the facts, but they appear deluded enough that they get their panties in a wad if you point out that their claims are false.  “I’m not a liar!” they’ll retort with indignation good enough to make them rivals of the Portugal soccer squad’s acting, or just crazy enough to fail to recognize their errors.

And so the falsehoods spiral on virally.

Rachel Carson’s ghost should get busier.  DDT can’t stop malaria, and now rarely slows it at all.  Rachel Carson was right — and had we listened in 1962, malaria might be a lot less prevalent today.


Red State: You’ll hear the banjoes

November 8, 2010

Somebody linked over to Red State.  What a creepy site.

First, it looks like those old ’50s school films about the creeping “Red Menace,” the way they paint every state Commie Red (no, I know they’re not conscious commies, but let’s call the color what it is).  It’s as if they have no knowledge of history over there, and they’ve never noticed.  It’s pretty clear that they have no desire nor need for white and blue, even to make “red, white and blue.”

Cover of record with "Dueling Banjoes"

If you have it on vinyl, you know what we mean.

Second, they brook no dissent at all.  Their terms of use (no open discussion) show the Red Staters get to decide whether you’re with the Red State Big Brother program — and if for any reason they decide you’re not toeing the party line, you’re vanquished.  No appeals.  “It’s not really an echo chamber, it’s unison singing.”

Third, there is the astonishing sucking sound where brains of skeptics should be.  Pick the stupid side of almost any issue, and it’s represented in spades there.  On the sciency front, for example, Red Staters have no use nor knowledge of Darwin, they think the warming temperatures of the climate are faked, probably by unholy, non-Red Stater weathermen, and they are convinced that the UN and others are using malaria for “population control” — so they favor massive amounts of DDT.

Remember Mr. Urquhart, the Delaware Tea Partier who, by the grace of God, lost the race for the state’s seat in the U.S. House of Representatives, and his claim that “separation of church and state” was Hitler’s idea?  Urquhart appears to drift in the mainstream at Red State.

Try it.  Pick an issue, do a search at Red State to see if they don’t favor the stupid side, and see whether any real facts can get in.  Even the news that shows their positions wrong, say their position against more stimulus, they’ll spin to say it’s the other guy’s fault.

God save us.  It’s a new Red to fear, the new Red Scare.

Lancet special issue on malaria eradication: No call for more DDT

October 30, 2010

Lancet is one of the premiere research journals in the world for all of science, but especially for issues of health and medicine.

Image from Lancet illustrating malaria story

Image from Lancet –
Mother and child under a mosquito bite-preventing bednet.

On October 29, 2010, Lancet published a special report, “Malaria Elimination.”  Much science.  Much history.  No call for more DDT.

A plan for research is laid out.  Plans to eradicate malaria from more than 90 nations are laid out, explained and debated.  Calls for more research are made.  Calls for disciplined action from nations and health care organizations, and donor organizations.

But no call for more DDT.

Go take a look at the issue.  Several of the articles are available for no charge, out from behind the usual Lancet paywall.

Get the real science, real history, real policy.  Environmentalists are not evil villains there.  malaria is the villain in that story, and serious health care researchers and deliverers discuss serious methods to beat the disease.  Consequently, DDT has only a bit part.

DDT hoaxsters predictably spinning India/malaria deaths story — wrongly

October 28, 2010

People so wedded to a hoax, or just wrong, view of events cannot be swayed away from their convictions easily.

Elizabeth Whelan’s hoax science policy group, the American Council on Science and Health (ACSH), put out a press release taking note of the study published in Lancet that calls into question the count of malaria deaths in India promulgated by the World Health Organization (WHO).  You remember, the study suggests the malaria death toll among adults in India may be as high as 200,000 annually, compared to the 15,000 estimated by WHO.

ACSH can’t resist the spin.  Implicit the debunking may be, but the study thoroughly debunks ACSH’s claim that more DDT will help defeat malaria.  India is the world’s greatest user of DDT, using more than all the rest of the world together.  Clearly a surplus usage of DDT has not created the miracle end to malaria that ACSH and other hoaxsters claim it would.

Still, ACSH sticks to their views, even when those views are grossly wrong.  ACSH said, “ACSH has called for resumed use of indoor residual spraying of small amounts of DDT to prevent mosquito bites, repel mosquitoes, and reduce malaria deaths.”

No word from India on whether it will dramatically reduce DDT use to meet ACSH’s call for “small amounts.”

ACSH’s press release calls attention to a Wall Street Journal Blog article describing WHO’s response to the Lancet-published study of India malaria deaths — WHO questions the “verbal autopsy” methodology, and says it stands by its estimates of malaria deaths in the nation:

“The new study uses verbal autopsy method which is suitable only for diseases with distinctive symptoms and not for malaria,” WHO’s India representative Nata Menabde said in an email statement Thursday.

The WHO says it takes into account only confirmed cases of malaria and surveys those using healthcare facilities.

Malaria symptoms include fever, flu-like illness and muscle aches. Malaria is endemic to parts of India, where many people live in mosquito-infested areas. Confirming the presence of malaria requires tests like the “Peripheral Smear for Malarial Parasite” and “Rapid Malaria Antigen”.

Lancet said the determinations made by its field researchers were reviewed by two of 130 trained doctors for all the 6,671 districts who determined whether or not the person had died from malaria.

The data concluded that 205,000 deaths before the age of 70, mainly in rural areas, were caused by malaria each year – 55,000 in early childhood, 30,000 among children ages five to 14 and 120,000 people 15 and older.

The WHO called for further review of the study.

“Malaria has symptoms common with many other diseases and cannot be correctly identified by the local population,” Dr. Menabde said, adding: “The findings of the study cannot be accepted without further validation.”


Called this one right: DDT advocates think poison is always the answer

October 25, 2010

This is a story about the persistence of bad information, and about the flow of news and other new information.

At about the same time I was writing about the Lancet study on potential undercounting of malaria deaths in India, Debora McKenzie at New Scientist pored over the same article (maybe the same Bloomberg News piece), and reported it in greater detail than I did here.  McKenzie’s piece is worthy of a read.

Glenn Reynolds, Instapundit

Glenn Reynolds, Instapundit

Glenn Reynolds at Instapundit picked up on McKenzie’s piece — but reflecting his pro-poison and anti-humanitarianism bias, he tacked on a gratuitous slap at health workers, scientists and governments who tried to eradicate malaria in the 20th century:

MALARIA KILLING MORE PEOPLE THAN WE THOUGHT?

Malaria has always been one of humanity’s biggest killers, but it may be far bigger than we realised. An unprecedented survey of the disease suggests that it kills between 125,000 and 277,000 people per year in India alone. In contrast, the World Health Organization puts India’s toll at just 16,000.

Other countries using similar accounting methods, such as Indonesia, may also be underestimating deaths from malaria. That means it could be killing many more than the WHO’s official estimate of nearly 1 million people a year worldwide, suggesting more money should be spent to fight it.

It’s too bad the malaria eradication efforts were allowed to fail.

“Allowed” to fail?  Reynolds assumes someone wanted the program to fail?  Reynolds assumes someone could have stopped the failure, other than the pro-DDT forces who overused the stuff and drove mosquitoes to evolve resistance, or other than the governments of Subsaharan Africa who could not mount massive health care campaigns due to the instability of their governments?  It’s too bad the program failed — it was mighty ambitious.  “Allowed to fail” is an undeserved slap at malaria fighters like Fred Soper.

This slip to finger-pointing is what I warned about in my post:  Though India is the world’s greatest manufacturer of DDT, and though more DDT is used in India today than the rest of the world combined, someone will look at the undercount story, blame the imaginary ban on DDT, blame Rachel Carson (who never advocated a ban on DDT), and make some smug political snark.

Reynolds was pulled away from the snark, fortunately.  Reader Kevin O’Brien wrote to Reynolds about  the difficulties of beating any disease, using smallpox as his launching point.  Beating smallpox was a massive effort, made easier by the fact that the pox resided only in humans, as opposed to the malaria parasite’s two-species life cycle.  O’Brien’s missive to Reynolds, a few errors included, is the best commentary Reynolds has had on DDT and disease in some time.

One frequently-obnoxious blogger pulled back from the brink is not enough, though.

Andrew Bolt

Andrew Bolt

Andrew Bolt jumped the shark at his blog for the Melbourne (Australia) Daily Sun.  The headline for his post is inflammatory and wrong, and warns us that most of what Bolt writes will be wrong:

How many children did Carson’s green lies kill?

Foolish hope that DDT could be a magic bullet against malaria, like Bolt’s,  helps frustrate workable plans to fight the disease.  Policy makers being convinced that some political conspiracy keeps DDT from working to beat malaria, in effect kills children.  Fighting malaria requires long, hard work, to bolster health care systems in entire nations, to accurately and quickly diagnose malaria, and to provide complete treatment to cure human victims.  That work is hampered by policy makers and popular opinion who hold that DDT would be cheaper and quicker, and effective.  Bolt takes any source, no matter how scurrilous, in his unholy condemnation of conservationists and scientists, especially Rachel Carson.  His sole source to condemn Carson is a publication from the far, far-fringe.

How many children will Bolt’s brown lies kill? one could ask.

I warned earlier:

Watch.  Advocates of poisoning Africa and Asia will claim scientists and environmental activists are somehow to blame for any underreporting, and they will call for more DDT use, claiming a ban has made India a refuge for malaria.  Those reports will fail to mention India’s heavy DDT use already, nor will they suggest an ineffectiveness of the nearly-sacred powder.

Andrew Bolt, you’ve made me a prophet — a saddened and disappointed prophet.  It’s good to see Glenn Reynolds step back from the brink of hysteria.  It’s too bad Bolt took the plunge.  Others will probably follow Bolt.

How far will the bad claims spread?


Malaria deaths in India under-reported? Bad news for pro-DDT partisans

October 22, 2010

Malaria hotspots in India. Image from Nature magazine, 2010. News report on Lancet study that suggests mortality from malaria in India may be significantly higher than WHO reports indicate.

Good news from the war on malaria has been that annual deaths are calculated to be fewer than 1 million annually, as low as 880,000 a year — the lowest human death toll from malaria in human history.

Researchers in India suggest that deaths there are grossly underreported, however — not the 15,000 estimated by the World Health Organization, but closer to 200,000 deaths a year, nearly 15 times as great.

Reading that news, DDT partisans might get a little race of the pulse thinking that this might improve the urgency for the case for using more DDT, as advocated in several hoax health campaigns and media, such as the recent film “3 Billion and Counting.”

The problem, though, is that India is one of the few places where DDT manufacturing continues today, and India is one of the nations where DDT use is relatively unregulated and heavy.  In short, if DDT were the miracle powder it’s claimed to be, any finding that malaria deaths are 15 times greater than reported by WHO is nails in the coffin of DDT advocacy.

Bloomberg News reported:

Researchers based their estimate on interviews with family members of more than 122,000 people who died between 2001 and 2003. The numbers “greatly exceed” the WHO estimates of 15,000 malaria deaths in India each year, the researchers wrote in the study, published today in the journal The Lancet.

“It shows that malaria kills far more people than previously supposed,” said one of the study authors, Prabhat Jha of the Center for Global Health Research in Toronto, in a statement. “This is the first nationwide study that has collected information on causes of death directly from communities.”

Remote regions may have an undocumented malaria burden, because conventional methods of tracking the disease are flawed, according to the authors. In India, the government malaria data, which is used by the Geneva-based WHO, only counts patients who had tested positive for the disease at a hospital or clinic. Others who died of symptoms closely resembling the malady but didn’t get a blood test aren’t included, co-author Vinod Sharma of the Indian Institute of Technology in New Delhi said in an interview today.

The lack of accurate data may hinder efforts by governments and aid organizations to provide diagnosis and treatment to the population at risk, the authors said.

Watch.  Advocates of poisoning Africa and Asia will claim scientists and environmental activists are somehow to blame for any underreporting, and they will call for more DDT use, claiming a ban has made India a refuge for malaria.  Those reports will fail to mention India’s heavy DDT use already, nor will they suggest an ineffectiveness of the nearly-sacred powder.

The article in the Lancet became available on-line on October 21 — it’s a 4.5 megabyte .pdf document:  “Adult and child malaria mortality in India: a nationally representative mortality survey.” A team of researchers is listed as authors of the study:  Neeraj Dhingra, Prabhat Jha, Vinod P Sharma, Alan A Cohen, Raju M Jotkar, Peter S Rodriguez, Diego G Bassani, Wilson Suraweera,Ramanan Laxminarayan, Richard Peto, for the Million Death Study Collaborators.

Accurate counts of infections and deaths provide essential information for effective programming of the fight against the disease.  Researchers point no particular fingers, but make the case in the article that better methods of counting and estimating malaria deaths must be found.

There are about 1·3 million deaths from infectious diseases before age 70 in rural areas in which fever is the main symptom. If there are large numbers of deaths from undiagnosed and untreated malaria in some parts of rural India then any method of estimating overall malaria deaths must rely, directly or indirectly, on evidence of uncertain reliability from non-medical informants and, although our method of estimating malaria mortality has weaknesses, indirect methods may be even less reliable. The major source of uncertainty in our estimates arises from the possible misclassifi cation of malaria deaths as deaths from other diseases, and vice versa. There is no wholly satisfactory method to quantify the inherent uncertainty in this, and indeed the use of statistical methods to quantify uncertainty can convey a false precision. However, even if we restrict our analyses to deaths immediately classifi ed by both physician coders as malaria, WHO estimates (15 000 deaths per year at all ages)1 are only one-eighth of our lower bound of malaria deaths in India (125 000 deaths below the age of 70 years; of which about 18 000 would have been in health-care facilities).

Our study suggests that the low WHO estimate of malaria deaths in India (and only 100 000 adult malaria deaths per year worldwide) should be reconsidered. If WHO estimates of malaria deaths in India or among adults worldwide are likely to be serious underestimates, this could substantially change disease control strategies, particularly in the rural parts of states with high malaria burden. Better estimates of malaria incidence and of malaria mortality in India, Africa, and elsewhere will provide a more rational foundation for the current debates about funding for preventive measures, about the need for more rapid access to malaria diagnosis, and about affordable access in the community to effective antimalarial drugs for children and adults.

How evolution makes bedbugs resistant to DDT

October 12, 2010

Our internet’s best expert in bedbugs, Bug Girl, recently featured another post relating how DDT drove evolution of bedbugs, so that bedbugs are no longer susceptible to DDT.  You should go read what Bug Girl said.

And you can view the video here, too; let’s spread the word, eh?

As Bug Girl describes it:

I discovered that bed bug evolution–specifically resistance to pesticides–was also the subject of the National Evolutionary Synthesis Center‘s podcast this month.  A FASCINATING interview with one of the grand old men of evolutionary genetics, James Crow.  He worked on DDT resistance back in the late 40s and 50s.

“3 billion and counting” — the errors one makes when using Howard Stern as a science advisor

October 7, 2010

“3 Billion and Counting” premiered at a tiny New York venue a couple of weeks ago, the latest skirmish in the War on Science. Physician-to-the-stars Dr. Rutledge Taylor claims that malaria could be eradicated if only DDT had not been banned from Africa.

What?  No, no, you’re right: DDT has never been banned from Africa, not even under the 2001 Persistent Organic Pollutants Treaty.  The film comes out of Hollywood, starring a Hollywood physician.  Perhaps that should clue us in that it is not a serious documentary, and not to be taken at face value.

Nor at any value.

Taylor engaged a publicist and conducted a national campaign to launch the movie.  In that campaign he someone appeared on Howard Stern’s radio show.  [There’s a guy in comments who claims it wasn’t Taylor, though Taylor wrote it in the first person.  Odd as hell.]

How silly are the claims in the movie?

A post at the movie’s blog revealed that Ronnie, Stern’s limousine driver, had a fight with bedbugs, and that Stern thinks DDT should be brought back.  That’s how bad this movie is:  Howard Stern is the science advisor.

Yes, yes, you’re right:  DDT stopped working against bedbugs in the 1950s (see Bug Girl’s recent post).  That doesn’t stop the publicists from defending the movie at the movie’s blog.  “Royce” [who claims not to be a publicist for the movie] said:

The problem with DDT is that it worked too well in stomping out malaria. The science proves that it minimally impacted the environment. But this information was suppressed. Wonder why and by whom? This movies addresses and uncovers the answers to these questions..Questions that many of us had about this issue.

I tried, without success I’m sure, to set him straight:

Royce,

First, DDT was not the weapon that eradicated malaria in the U.S.  We worked for 30 years to improve medical care, beef up the Public Health Service and county public health officers, educate people on how to drain mosquito breeding areas near their homes, be certain people with malari were fully treated to a cure, and to raise incomes to improve housing so that people could live in a home where mosquitoes could not enter at night (the times malaria-carrying mosquitoes bite).  By 1939, malaria was essentially eliminated from the U.S.  DDT was not available for use for another seven years.

Earlier we had defeated malaria and yellow fever in Panama, during the construction of the Panama Canal — long before any insecticide existed.  Beating malaria is possible with discipline, accurate information, and sustained effort.  No pesticide is necessary.

Second, DDT has never been out of use in Africa since 1946, nor in Asia.  DDT is in use right now by the World Health Organization (WHO) and at least five nations in Africa who have malaria problems.  If someone told you DDT is not being used, they erred.

Unfortunately, overuse of DDT by agricultural interests, in the early 1960s, bred mosquitoes that are resitant and immune to DDT.  DDT simply is not the effective pesticide it once was, and for the WHO project to eradicate malaria, this problem was the death knell.  WHO had to fall back to a malaria control position, because pro-DDT groups sprayed far too much of the stuff, in far to many places, mostly outside.

Third, all serious studies indicate that DDT greatly affects environment, with doses of the stuff multiplying from application through the top of the trophic levels in the ecosystem.  A minimal dose of DDT to kill mosquito larva in an estuary, for example, multiples many times as zooplankton and the mosquito larva soak it up.  The next level of consumers get about a ten-times dose from what was sprayed, and that multiplies exponentially as other creatures consume the lower-level consumers.  By the time an insect or crustacean-eating bird gets the critter, the dose is millions of times stronger, often to fatal levels for the bird.

If the dose is sub-lethal, it screws up the reproduction of the bird.  DDT in the egg kills the chick before it can fledge from the nest, often before it can hatch.  If by some miracle the chick does not die from acute DDT poisoning, the eggshells produced by a DDT-tainted female bird are often too thin to survive the growth of the embryo — either way the chicks die.  (There are a couple of studies done on plant-eating birds which showed that the chicks did not die before hatching — they died shortly after hatching.)

DDT is astoundingly effective at screwing up the reproduction of birds.

Fourth, studies show that humans exposed to DDT rarely get an acutely toxic dose, but that their children get screwed up reproductive systems, and there is a definite link from DDT exposure to the children of the mother — the cancer goes to the next generation.  DDT is not harmless to people at all — it is just not acutely toxic, generally.

Fifth, as I note above, DDT is no longer highly effective in controlling mosquitoes.  Where once it killed them dead, they have developed immunity, and now digest the stuff as if it were food.  There are studies that show DDT is also weakly repellent, but there are better, less-toxic repellents, and there is no reason to use something so deadly to all other creatures in the ecosystem to get a weak repellent effect.

Because of the biomagnification, DDT kills the predators of mosquitoes much more effectively, and for a much longer period, than it kills mosquitoes.  This sets the stage for mosquitoes to come roaring back, with all the natural checks on mosquito population out of commission.

Why use a poison that is not very effective, but very deadly, when there are better alternatives available?

Malaria death rates are the lowest they have been in human history.  There is no good case to be made that more DDT could provide any benefit.

DDT is still manufactured in astonishing quantity in North Korea, for one.  DDT is used in Africa and Asia, but no one with any sense uses it to eradicate malaria — DDT screwed up that chance 50 years ago.

Rutledge’s movie appears to be sinking from release (it’s played two theaters that I can find, for less than a week at each).  It may be far underwater already.  It would be to DDT whatExpelled” was to creationism, but it lacks the cloying, gullible religious fanatics to push it.

Thank God.

Tupper takes up the quill

September 23, 2010

Karl Tupper of the Pesticide Action Network started blogging at PAN’s site, GroundTruth, a few days ago.  His carefully-thought out, informative writing turns to the issue of bedbugs and DDT in his first post.

GroundTruth, the blog of the Pesticide Action Network

Is there room for another blog?  Any blogging about science, with accuracy, is always welcome.

Karl’s second post updates us on EPA’s hearings on atrazine, and the industry campaign to slander any agency who dares to ask the tough questions about chemical safety.  Shades of the 1962 campaign against Rachel Carson, eh?


Truth in a fair fight: Eli Rabett explains Gates Foundation’s good work against malaria

September 21, 2010

Good works are oft’ interred with the bones of the good workers, according to that Brutus Mark Antony guy — and at Watts Up With That, many work to bury any good workers, too.

So, a specially-scrubbed carrot is due Eli Rabett, who details the good works of the Gates Foundation against malaria, just to counteract the clamor of the howling at WUWT.

. . . since this started with an attack on Bill Gates, it is important to understand at least some of the interesting things that the Gates Foundation is doing to help fight malaria.

Among these, Affordable Medicines for Malaria (AMFM), is one of the cleverest, and may even work. The idea is that AMFM will buy ACT (artemisinin combination therapy – something else the Wattoids didn’t know about) drugs directly from the manufacturers in huge amounts at deep discount, and pass the drugs on to the distributors, public health agencies, private wholesale pharmacies, and NGOs at so far below cost that even counterfeit drugs cost more. The private wholesalers can take their profit.

One may hope someone will find the magic bullet to fight malaria.  There’s the Ghost of Santayana pacing the chalkboard again, however:  Our experience shows that magic is not real, no magic bullet has ever existed against malaria, and DDT is not now the magic bullet it never was in the first place.  “Those who cannot remember the past are condemned to repeat it,” Ghost of Santayana mutters.

A special place in hell is reserved for those who remember the past, but tell false tales about it instead.


Still evil and wrong: McIlhinney still leads a cover up of malaria facts

September 20, 2010

U.S. President’s Malaria Initiative (PMI) Africa Indoor Residual Spraying (AIRS) Project found this warehouse with 119 tons of leftover, surplus and expired DDT in Ethiopia. In total, PMI AIRS Progect found 930 tons of unused DDT in Ethiopia, in 1,600 tons of expired pesticides total. Other nations have other surplus DDT stocks. Africa never suffered a shortage of DDT.

Watch the video, and you can see God trying to stop her from talking, putting that frog in her throat.

Ann McIlhinney was wrong when she made the movie “Not Evil, Just Wrong,” and she’s still spreading false tales.  I found her diatribe, interestingly enough at a site called 2012 Doomsday Predictions.

I only respond to the first six minutes or so — you get the idea.  McIlhinney leaves no falsehood untold, no crazy charge not leveled at Rachel Carson and “environmentalists.”

Here’s the film clip of McIlhinney misleading the masses:

Here is my quick and dirty response:

1. Environmentalists are not calling for a ban on coal, oil or gas. Fear talk. Why would anyone tell such a whopping lie? How do we know the film lies? Who is this “environmentalist” they fear to name?

2. Rachel Carson was right — DDT kills ecosystems. Carson said we needed to restrict the use of DDT in order to keep it viable as a pesticide. But few listened (not McIlhinney, that’s for sure). Consequently, DDT became ineffective against mosquitoes that carry malaria, scuttling the World Health Organization’s ambitious campaign to eradicate malaria. Had that not happened, and had we eradicated malaria by 1975 as planned, millions of lives could have been saved. McIlhinney is the one with blood on her hands.

3. DDT has never been banned worldwide, was never banned in Africa, and is still used in those places it still works, under a special treaty signed in 2001. McIlhinney hopes you won’t know about that treaty, and fails to mention it herself. What’s she trying to hide?

4. Carson did not say DDT was the sole culprit for the decline of birds — but by 1962, it was the sole culprit preventing their recovery. Bald eagles and brown pelicans have come off the endangered species list, populations recovering in almost lock-step with the decline of DDT in the birds’ flesh — proof that Carson was right.

5. Under U.S. law, no agency could ban a useful pesticide without mountains of evidence that the pesticide was dangerous. Four separate court proceedings looked at DDT, two before the EPA acted, and two appeals after EPA banned DDT use on crops. All four courts found DDT to be dangerous and uncontrollable in the wild. The two appeals of EPA’s labeling change were both decided on summary judgment — the science was so powerfully on Carson’s side. In May 1963 the President’s Science Advisory Council reported on their fact checking of Carson’s book — they said Carson was dead right in everything but one: Carson was too easy on DDT. That panel, with its significant population of Nobel winners, called for quick action against DDT. Why doesn’t McIlhinney give the facts here?

6. The claim that EPA’s ban influenced WHO is pure bullfeathers. WHO had to end its malaria eradication campaign, using DDT, in 1965 — the mosquitoes were immune to the stuff. EPA didn’t act until seven years later, and EPA’s jurisdiction extends only to the borders of the U.S. In fact, EPA’s “ban” left DDT to be manufactured in the U.S. for export to Africa. Can’t McIlhinney read a calendar? The “ban” in 1972 did not travel back through time to stop WHO from using DDT. (For that matter, WHO never completely stopped DDT — wherever it could work, they used it, and still do.)

7. DDT has always been available for any government in Africa to use. What that guy in the film is really saying is racist: He’s claiming Africans were too stupid to use DDT, though it was cheap and available, and though it would save their lives. Don’t listen to him. Africans are not stupid: They’d use DDT were it effective and safe. Shame on McIlhinney for entertaining such a claim.

8. Malaria did not skyrocket after DDT was banned in the U.S. Mosquitoes don’t migrate that far. There was an uptick in malaria 20 years later, when the pharmaceuticals that cure malaria in humans, ceased to be effective.

But today, malaria rates are the lowest they’ve been in recorded history, and malaria death rates are the lowest they’ve been in human history. When the U.S. banned DDT spraying on cotton in 1972, about 2 million people a year died from malaria. Today, the death toll is under 900,000. Don’t be frightened or stampeded by erroneous, large figures.

In the end, we can’t poison Africa to health, and if we could, it would be immoral to do that instead of building health care to fight diseases.

Children die because hard-hearted politicos like Ann McIlhinney frustrate the work of malaria fighters, and mislead policy makers away from solutions that would save children’s lives.

Shame on her.
