DDT does break down once released into the wild, and can do so rather quickly, DDT advocates love to point out. It’s part of the sleight-of-hand necessary to argue for DDT. Yes, DDT breaks down, but the first step is a breakdown to the more resilient and consequently more damaging substance known as DDE.
DDE mimics endocrine hormones in the wild and has been implicated in gender ambiguity in alligators, fish and amphibians. These animals feature underdeveloped male sex organs, are often hermaphroditic, and sometimes unable to breed. Endocrine mimics — not always DDE — are implicated in swelling the breasts of male mammals (humans are mammals, by the way), and shrinking testes in animals of all kinds.
Some studies suggest that something causes women’s ability to produce milk to nurse infants is significantly curtailed. A few studies suggest DDE is the culprit.
From a lawyer’s blog, I learned of a study in Mexico that showed no significant discernible link between DDE and the length of lactation (milk production). Something else appears to be injuring these women and their babies.
They conclude that the data from this relatively large study in a highly exposed area of Mexico did not support the hypothesis that exposure to DDE shortens length of lactation, and thus the association seen in women who previously breast-fed was likely attributed to a noncausal mechanism. Nonetheless, the authors note that DDT may have other potential adverse effects which are in need of study.
The blog post is written by Thomas H. Clarke, Jr., J.D., M.S., Chair of the Ropers Majeski Kohn & Bentley Environmental Practice Group. The blog, Ear to the Ground, is new this month so far as I can tell — in this case it’s useful because it has a workable link to the full text of the article in Environmental Health Perspectives (in case you are, as I am, too lazy to get your own free subscription).
How will the DDT advocates spin this one? Look for pronouncements that DDT “absolutely has no effect on human lactation.” And look out for them — that’s not what this study says at all.

News comes out of Kampala that the delay in implementing the use of DDT in a Rachel Carson-approved program of integrated pest management — for indoor residual spraying only — faces strong opposition.
From environmentalists? No, you’ll recall that Environmental Defense, the group that led the fight for a ban on broadcast use of DDT in the U.S. has been pressuring the Bush administration and others to use DDT appropriately for years.
The opposition comes from Uganda businesses.
“Zero tolerance on DDT spraying is the feeling of the private sector. Even at the East African Community DDT is a condemned chemical. Government should look for other alternatives,” Mr David Lule, the managing director of Hortexa, a horticultural exporting association to the EU [European Union], said.
Don’t look for corrections or apologies from the pro-poison lobbyists yet. Junk “scientist” Steven Milloy, the “Competitive Enterprise Institute” (which claims to represent businesses) and others have yet to correct any of the many errors they’ve made in their slash-and-burn campaign for poisoning Africa. Why would they change now?

On the eve of a major conference on health effects of DDT, the U.S. Centers for Disease Control published a study it had suppressed for several months, detailing pollution effects in the Great Lakes area. The author of the study, demoted but still outspoken, was grudgingly granted permission to attend the Kenaga International Conference on DDT and Health, which opened yesterday at Alma College in Alma, Michigan.
Science won the skirmish, getting the study pried out of CDC. News coverage of the conference stopped short of spectacular so far: Only local Michigan media outlets provided coverage. If we won the war, but no one knew . . . ?
The Morning Sun suggested that further studies of health effects in the area are required, and that no successful cleanup of a toxic site is ever done without health studies showing the need.
[Jane] Keon[, chairwoman of the Pine River Superfund Citizen Task Force] hasn’t read the entire report but did read the portions about Gratiot County.
“There’s no new information, and everything mentioned is well-known and verified by ATSDR and CDC,” she said. “I understand that in addition to 200 researchers and much peer review the report data was reviewed by state and local health departments in the areas of concern without the complaint that the science was weak.
“We in the task force view the report as further proof that a full-blown health study is needed in Gratiot County. From our own studies we also know that communities with contaminated sites that have a health study to point to get very thorough cleanups, while communities that do not have a health study do not get thorough cleanups.”
The task force has twice applied for grants to perform a comprehensive local heath study but were turned down both times.
“The reasons offered (for rejection) seemed lame and illogical,” Keon said. “One time we were told that we didn’t have enough data, and yet that is why we desired the health study – to have a scientific collection of data.”
A citizens’ group in Washington, D.C., the Center for Public Integrity, obtained a copy of the study last year and made it available on the internet. There is no indication I can find of whether there were changes made in the study between the leaking and the formal publication.

March 14 beckons from the near horizon. A group of scientists and policy wonks will gather at Alma College, in Alma, Michigan, to look at the issues of DDT and health. This is the first major conference of its kind since the POPs Treaty, at least.
Controversy again swirls around DDT, with a large industry campaign again after the reputation of Rachel Carson just the same as in 1963 — though Ms. Carson has been dead since 1964. The disinformation campaign also impugns environmentalists, health care workers (especially if they’ve ever worked for the World Health Organization), Al Gore (there is no rationale), and when the minions think they can get away with it, it impugns bed nets and stagnant pool draining.
This public relations campaign against Rachel Carson enjoys a great deal of success. Oklahoma’s Sen. Tom Coburn, who seems never to have met an insult to a scientist he couldn’t use, successfully stopped the U.S. Senate from passing a bill naming a post office in honor of Rachel Carson, one of Coburn’s greatest legislative achievements. Several people in Congress, including Utah’s Rep. Rob Bishop, were similarly hornswoggled.
This conference could put real, accurate information in front of the public.
Are my expectations way too high? I hope reporting from this conference might inject sanity, comity, humility and courtesy back into the discussions of how to treat malaria, and whether DDT should ever be used.
Associated Press? Reuters? New York Times? Chicago Tribune? Detroit News, or Detroit Free Press? Lansing State Journal?
Who will report from the conference?
I hope major news outlets will have reporters there.

Current issue of On Earth (Winter 2008), an article by Kim Larsen about fighting malaria in Africa, “Bad Blood”:
DDT can interfere with the feedback loop in the pituitary gland, which releases the milk-producing hormone prolactin. Studies show that exposure to DDT at critical points in pregnancy or just after childbirth can reduce the output of breast milk, or even dry it up. In such instances the mother will turn to formula, which is expensive. And in Africa formula feeding often leads to another death sentence for babies: diarrhea (infants have no immunity to the microbes that abound in contaminated drinking water throughout much of the continent). Here, then, exposure to DDT may cause as swift and bleak an outcome as exposure to a mosquito.
On Earth is a publication of the Natural Resources Defense Council (NRDC).

I love irony.
Henry VIII devised a novel way to save money. He ordered coins be minted containing silver, as during the reign of Henry VII, but he ordered that the purity of the silver be reduced. Edward VI continued the policy so that, by the time of the rule of Queen Elizabeth I, royal advisor and financier Sir Thomas Gresham observed that most of the old, high-silver content coins were out of circulation, hoarded by people against future inflation, allowing the lesser-valued money to circulate. Gresham told Elizabeth the bad money drove out the good money.
Sir Thomas Gresham (c. 1519 – 21 November 1579), British financier and advisor to Queen Elizabeth I and earlier regents. Portrait c. 1554 by Anthonis Mor.
The principle had been observed earlier by Aristophanes and others. It is known in modern economics as Gresham’s Law, since 1858 when British economist Henry Dunning McLeod decided to honor Gresham by naming the rule after him.
The bad drives out the good, the cheap drives out the more expensive, gossip drives out good information — the principle is widely observed in areas beyond economics.
And so it is that with regard to DDT, the good information about the dangers of DDT and the benefits of restricting use of the chemical has been driven out of the marketplace by bad information claiming DDT is safe, and ignoring the significant benefits reaped when massive use of DDT was stopped.
And here’s the irony: DDT-happy critics of good environmental policy now claim to be the good information driven out by the “bad” information of DDT’s harms. No kidding. A columnist named Natalie Sirkin, in a column delivering almost nothing but bad, vile information, says bad information drives out the good, never once noting the irony.
The defense of DDT was, from the beginning, a lost cause. A few of us vainly hoped that science would prevail. We soon found that Gresham ’s Law, which states that bad currency drives out good currency, applies to science as well as to economics.
No kidding it applies. Do a Google search for “DDT” today and you’ll find all over the internet the disinformation of Gordon Edwards’ ghost and junk science purveyor Steven Milloy. You will have a difficult time finding any solid study showing how DDT nearly killed off the American bald eagle, however, and you’ll have to do a targeted search to learn of any dangers of DDT — information on human toxicity is almost impossible to find, though it’s easy to find many recountings of Gordon Edwards’ bold drinking of a teaspoon of DDT before lectures.
(Natalie and Gerald Sirkin write for the American Spectator; at this writing, Google features warnings on all of their material at the time of this writing, saying the site host may try to insert “malicious software” on your computer — so I have not linked there. This problem should sort itself out, I hope.)
(The Environmental Protection Agency (EPA) works to get a history of the agency up on the ‘net; a lot from the DDT ban era is now available at the EPA site for scholars; Milloy will not be happy to have factual rebuttal officially and easily available.)
Below the fold, I’ll offer a point-by-point rebuttal of the bizarre claims in favor of DDT and against the noble public officials who worked to restrict its use.

So, if you check the comments over at Neil Simpson’s blog, somebody asked about the post Simpson deleted, and Simpson answered:
Didn’t read the thing? Heh. Figures. The comment reveals the depths of moral difficulty of the anti-Rachel Carson position — the position Simpson takes in the blog. Simpson can’t answer any of the criticisms. No, I didn’t change my e-mail address — Simpson’s blog was just more loving of correcting dissent than Simpson.
Personal attacks? Bullbleep. Simpson thinks any correction is “a personal attack.” If one is chronically in error about the facts, and chronically belligerent about dealing with data, one gets a lot of corrections.
Here’s a challenge to Simpson: This blog is open. I’ll edit out only your profanities if you use them. But I’ll wager you can’t defend your position. I won’t go Joe Stalin on you the way you did on me.
Neil, you’re in error about Carson’s book. You’re wrong. You have a Christian duty to fix the errors. Bet you won’t.
Marshall Art, if you’re interested, you can read the remarks Simpson won’t read, here. Now you know why, in my opinion, he’s afraid to read them. The comment isn’t even snarky, though heaven knows there’d be a right.

Meanwhile, back in reality, the International Society for Environmental Epidemiology signed on to cosponsor the conference on DDT’s effects on human health and the environment at Alma College in Michigan, set for March 14.

Religionists and conservative pundits won’t boycott the conference. But they won’t be there, either, I’ll wager. They don’t want to confuse their rants with the facts, you see.
Do we know any bloggers up Alma College way (Alma, Michigan, in the heart of the peninsula) who might attend the conference and provide hourly reports? Ed Brayton, are you close? Got a day to play blog journalist for a good cause?

Anti-science and anti-environment protection advocates appear to be ramping up their campaign to poison Africa with DDT. Whether it’s related to U.S. President George Bush’s last-gasp trip to Africa or something else, is difficult to determine.
The vicious campaign is popping up everywhere. Is there too much vitriol against sanity to be more than coincidence?
Religionist Neil Simpson’s poke in the eye of reason got me going this time. In “Dangerous environmentalism” he hits just about every false claim against environmentalists and every false claim for DDT in just a few paragraphs — he got it from Steve Forbes and repeated it without bothering to consider whether Forbes was engaging in ill-informed rant.
Steve Forbes doesn’t know much about the history, science or law of DDT or malaria, but that never stops him from opining that others are dead wrong in what they do know.
The rant hits so many of the favorite punching bags of the modern angry white male bigot: Intellectuals (those scientists and environmentalists with their college degrees), women and women’s rights (Rachel Carson didn’t marry, and fought her way to prominence in fields men dominated), history (they wish it weren’t so, and if they repeat what they want history to have been, maybe Santayana’s Ghost will leave them alone — not that they are ever bothered by repeating historical error), race (never miss a chance to accuse scientists, environmentalists, intellectuals and other “liberals” with race bigotry), foreign aid (see, we can just poison Africa back to health — if you’d just stop sending them money for bed nets and good medical care, DDT is all they need).
This is the money line from Forbes:
Yet in one of history’s more murderously myopic ongoing actions, most advanced countries and international agencies discourage its use. Why? Blame Rachel Carson’s seismically influential–and now largely discredited–book, Silent Spring, first published in 1962. In it she blames DDT for imperiling birds and people, portraying it as a blight of almost biblical proportions. It ain’t so. As Dr. Elizabeth Whelan of the American Council on Science & Health once put it, there “has never been a documented case of human illness or death in the U.S. as a result of the standard and accepted use of pesticides.” The British medical journal The Lancet similarly notes that after 40 years of research no significant health threat from DDT has been found.
Count the errors:
- The treaty that regulates the phase out of long-lasting, environmentally-damaging and human-killing poisons has a carve-out provision that specifically allows the use of DDT for limited indoor use (see Annex B); this treaty was negotiated at the end of the 20th century, eight years ago [1999 taking effect in 2001]. It represents the official position of “advanced countries and international agencies.” The treaty position is exactly the opposite of Forbes’ claim. How many years behind is Forbes in his reading? one might wonder.
- No one has ever discredited any significant part of Rachel Carson’s book, Silent Spring. Exactly contrary to Forbes’ claim, the book was found to be scientifically solid by a specially-appointed group of science advisors to President Kennedy, in 1963 [full text of “Use of Pesticides,” here]; it was found solid by later research by the U.S. Fish and Wildlife Service, the U.S. Department of Agriculture, and the U.S. Environmental Protection Agency. Discover Magazine recently noted that there are more than 1,000 follow-up references since 1962 that verify Carson’s work.*
- Carson’s book accurately noted the damage to birds — not a single incident she recounts has ever been seriously questioned. The stories have been distorted and wild claims made against the distortions — but there is not a single study anywhere which contradicts Carson’s claims about damage to birds. Carson worried about human health effects, but stopped far short of saying DDT kills humans. Subsequent research has won DDT a listing as a probable human carcinogen by all of the world’s most respected and conservative health agencies, every single one.
- Elizabeth Whelan’s career is built on slamming scientists and science. But apart from the dubious provenance of the source, look at what Forbes quotes her as saying. Never a death in the U.S. as a result of using DDT in the limited way it’s now used in the U.S. There have been deaths outside the U.S. (and my recollection is at least one in the U.S.); and the methods that have prevented deaths are the banning of DDT for broadcast use, and extremely limited use at any time. She’s right: No deaths can be attributed to the non-use of DDT. She doesn’t say DDT isn’t a poison, or that it is not carcinogenic. She doesn’t account for deaths outside the U.S. She doesn’t get close to accounting for damage to wildlife and African food supplies from DDT. Half-truth to whole lie.
(It is often useful to remind critics that DDT was not banned because of dangers to human health, but instead because of its damage to beneficial animals outdoors. It’s also good to remind them that DDT was specifically reinserted into disease fighting by the EPA order in 1972 that banned DDT use on crops, only in the U.S.)
Then, with no sense for the irony, Simpson extols the virtues of mosquito netting.
Mosquito nets are another inexpensive solution. See Nothing But Nets if you want to help.
The Nothing But Net drive faces implicit opposition chiefly from interests who claim poisoning with DDT is a better idea.
One wishes critics of Rachel Carson would show a bit of Christian charity, calling for bed nets, but avoiding unjustified and misinformed calumny against Carson and environmentalists, who have labored intensively for 40 years to fight malaria.
One gets the idea it’s not malaria these pundits worry about.
A few words about totalitarianism below the fold.

Steven Milloy must be apoplectic.
On March 14, 2008, Alma College, in Alma, Mich., is hosting a conference examining what is known about the impact of DDT on human health and the environment.
The conference will bring together a number of national and international experts to frame and lead discussions of current knowledge of DDT. Attendees will engage with experts to plan what research or other projects are needed to address questions about the impact of DDT and other persistent organic pollutants (POPs).
The conference is jointly sponsored by the Center for Responsible Leadership at Alma College, the Ohio Valley Chapter of the Society for Environmental Toxicology and Chemistry, and the Pine River Superfund Task Force, a U.S. Environmental Protection Agency (EPA) community advisory group (CAG) for Superfund sites in the Pine River watershed in Michigan.
Why Alma College?
For a number of years students and faculty at Alma have helped support the work of the Pine River Task Force. The Superfund sites in the watershed of the Pine River resulted from the massive dumping of byproducts from production of DDT and a fire retardant based upon polybrominated biphenyls (PBBs) by Velsicol Chemical Company. In addition to general dumping of wastes, Velsicol was responsible in 1973 for one of the worst food contamination mistakes in history, when PBB was erroneously mixed with animal feed and remained undetected for a year.
While highly contaminated for decades, the Pine River watershed has been fortunate to be the location of Alma College, with a long tradition of community involvement, and also the home of a number of people with remarkable expertise. One of the long time members of the CAG was the late Eugene Kenaga (1917-2007), for whom the conference is named.
Eugene Kenaga
During World War II, Dr. Kenaga served as an officer in a malariology unit in the Pacific Theater, using DDT. For forty-two years he was a research scientists with the Dow Chemical Company, for many years in charge of their entomological research. In 1968 he served on a three-member blue ribbon pesticide advisory panel (for Michigan Governor George Romney) that restricted use of DDT in the state. After the formation of EPA, he served on a variety of EPA advisory panels. He was also one of the founders of the International Society of Environmental Toxicology and Chemistry (SETAC).
And:
Recently, the College, SETAC, and Task Force have become aware of an international campaign that questions the national and international restrictions on the use of DDT. Knowledge of this campaign led to the decision to bring together international experts and concerned citizens to discuss what is known and needs to be known about the impacts on human health and the environment arising from exposure to DDT and the other POPs.
Serious scholars, academic rigor, real scientists, real science, government agencies charged with protecting human health and environmental quality, the Center for Responsible — will any of the DDT advocates have the backbone to show? They don’t appear to fit any of those categories.

New Vision, a website in Kampala, Uganda, via AllAfrica.com, notes that Uganda will start using DDT in residential spraying against mosquitoes, in February 2008.
Use of DDT would have started earlier, the article says, but for lack of money.
So, participants in the defense of wise environmental policy and Rachel Carson, against the scurrilous charges of junk science purveyors, should take note:
- There is no ban on use of DDT against mosquitoes, in a serious, controlled program of integrated pest management.
- No environmentalist is to blame for the lack of DDT use in Uganda (and probably elsewhere). As with anti-malaria programs worldwide, lack of funding or lack of organization generally is the reason for any lack of action against malaria.

One-paragraph in a story in the Philadelphia Daily Inquirer with a lot of impact:
A record number of bald eagles soared past Hawk Mountain in Berks County this fall, continuing a comeback that began with the banning of DDT in 1972. Then, 18 eagles were counted during the typical migration. The count this fall: 230. – Don Sapatkin
Caption from PennLive.com blog: Visitors and staff gather on the South Lookout at Hawk Mountain Sanctuary, near Kempton, Berks County. (HAWK MOUNTAIN SANCTUARY PHOTO) (Photo substituted here for previous photo noted below, which has gone missing in DatedLinksLand)
South Lookout at Hawk Mountain: The view from a rocky ledge near the entrance at Hawk Mountain provides a spectacular view of the countryside and is a good vantage point for watching migrating raptors in the fall. This photo was taken the afternoon of 10-16-2006. Public domain photo, via Answers.com.
The white area at upper center is the “River of Rocks”. According to http://www.hawkmountain.org, this formation is a mile-long boulder field, up to 40 feet deep, which was deposited 10,000-12,000 years ago (the end of the last Ice Age), when glaciers stopped 40-50 miles to the north of this location. Repeated freezing and thawing cracked boulders from the ridgetop that gradually slid to their current position.

Hey, wasn’t there some environmentalist’s post here earlier? Someone defending Carson’s position? What happened?
That might have been the comment I deleted. I didn’t read the whole thing. The guy must have changed his email address, because my filter usually blocks him. He was the first guy I ever had to block for repeated inane arguments and personal attacks. I gave him a lot of chances but in the end he was just not worth the time to discuss anything with.
