August 20 is World Mosquito Day:

Pause for a moment on World Mosquito Day to reflect on the little bloodsucker that probably causes more human suffering than any other organism. Observed annually today, August 20, World Mosquito Day originated in 1897 by Dr. Ronald Ross of the Liverpool School of Tropical Medicine, according to the American Mosquito Control Association, a nonprofit based in New Jersey.

Ross is credited with the discovery of the transmission of malaria by the mosquito, and was honored with a Nobel Prize for Medicine in 1902.

Each year 350-500 million cases of malaria occur worldwide, and over one million people die, most of them young children in sub-Saharan Africa, according to the Centers for Disease Control and Prevention.

But malaria is not the only disease spread by mosquitoes. There’s also West Nile virus, various strains of encephalitis, Dengue Fever, Rift Valley Fever, Yellow Fever.

An account of bioaccumulation of pesticides — dangers of DDT explained

August 14, 2008

Even short-time readers know of the problems of DDT advocates, denialists who seen to think we can poison our way to health — or worse, that we can poison others, in Africa, to health.

Here’s a voice from the other side, an Australian anti-pesticide, go-back-to-nature site, that tells a dramatic story from California:  The Permaculture Institute, “Pesticides, and You.” Clear Lake offered a dramatic example of the dangers of bioaccumulating chemicals, especially pesticides like DDT.

Without endorsing everything this group urges, I will say the clear, simple explanation of the events at Clear Lake is accurate, worth reading, and worth remembering.  It’s what Rachel Carson sounded the alarm to warn us about, and but for the movement spurred partly by her book, Silent Spring, it’s what we would have faced at countless other locations.

African nations back off of limited DDT use

August 7, 2008

Anti-DDT business interests appear triumphant, if only temporarily,  in their efforts to stop the use of DDT in the fight against malaria.

ProtectAfrica.com reports use of DDT has been stopped in northern UgandaNine corporations sued to stop the sprayingNew Visions reports a shift to a chemical named ICON for use in Indoor Residual Spraying, designed to protect people against mosquitoes in their homes.

I have links to stories saying Rwanda has abandoned DDT in the past few weeks, but none of the links work.

Meanwhile, from The East African in Nairobi, Kenya, comes the report that Tanzania became the first East African nation in recent years to use DDT for limited, indoor spraying. [But be wary of this source; the article also claims many nations outlawed DDT after 1972; not accurate in Africa, nor most other places.]

There is high irony in businesses opposing the use of DDT when environmental organizations in other nations do not oppose it.


DDT poisoning spreads: Critics Kling to their favorite untruths

August 4, 2008

No, I’m not talking about actual poisoning by the chemical, an organochloride insecticide. I’m talking again about people driven to madness by false claims that DDT will cure malaria, that DDT is banned for use against malaria, and that some few super powerful people, all of them evil environmentalists, are forcing governments, all health workers, and the world’s tobacco companies to stop the use of DDT — ergo, they say, everyone who has died from malaria since [some point in the past that is surely the fault of environmentalists] died due to lack of DDT.

Which makes those people worse murderers than Stalin at least, so the crazies claim.

Here’s the latest fuse that set me off. I’ll analyze it below the fold, after the lecture.

Is it a virus that spreads in late summer? I’ve noted here earlier the tendency of the pro-DDT wackoes to surge out of the woodwork in summer to claim, against the facts, that West Nile virus would be no problem if there were DDT. Mosquitoes that carry West Nile are best killed in as larva, living in water; DDT is not as efficient as other larvacides, particularly when weighed against DDT’s tendency to kill everything that comes in contact with the water and the plants and animals living in and around it.

But watch: Any mention of malaria in the news, and they drop letters to the editors of every weekly newspaper in America, blaming unnamed environmentalists for killing millions in Africa, or Asia, or both. In the Bizarro™ World of DDT advocates, all insect-borne diseases were on the run until Rachel Carson personally padlocked every DDT manufacturer in the world. I have news browsers set to pick up mentions of DDT, and except for the recent surge in news about the band DDT from Russia, every day brings another internet mention of how DDT could have saved the world, if only.

Dear Reader, Dear God, there are several inaccuracies there. It’s curious that some people can get ideas so exactly contrary to the facts, contrary to reality, so often.

Arnold Kling, economist blogging at the Freedom Fund's Library of Economics and Liberty -- in this case, misblogging against science and medicine.

Arnold Kling, economist blogging at the Freedom Fund’s Library of Economics and Liberty — in this case, misblogging against science and medicine.

Wait. What’s this? There’s a trail of misinformation and disinformation we can follow. This livejournal poster links to this Wikipedia article on “seasteading,” and from there to this blog on the value of seasteading, which bases the pie-in-the-sea philosophy on the common, occasionally-but-randomly correct rant against government, based on Arnold Kling’s rant at EconLog.

Have we seen this before? Yes, Dear Reader, we have — and if you look in the comments to Kling’s rant, you’ll see Tim Lambert fiercely shoveling facts to try to put out the fires of ignorance. I even posted there — back in April. The facts, the links, the arguments, are all there, for anyone with half a brain and half a desire to do the right thing and get the facts right.

April to August (misdated September). The nutty DDT advocates are working on a four month cycle. Repeat the falsehoods every four months, three times a year (intentionally or not; some viral marketing works better if it’s not intentional, like the innocent carriers of typhoid who are unaffected by it, don’t mean to spread it around, but breath the pathogen out with every breath).

Blather, don’t bother to rinse, repeat.

It’s time someone wrote a new book on propaganda, warning of its evils.

Uganda and malaria, from the inside

July 30, 2008

This is probably as close to we can come to know what’s going on inside Uganda, especially with regard to malaria and efforts to fight it there.  Go see Mars and Aesculapius, “World Malaria Day.

As you can see, simply pumping DDT into the countryside is unlikely to solve the problems.

News from Uganda? DDT, cotton, misreporting

July 13, 2008

In continuing efforts to slam environmentalists and Rachel Carson, Instapundit and RWDB complain (whine?) about the European Union’s efforts to block the importation of cotton from Uganda on fears of DDT contamination.

Meanwhile, back in Kampala, the news is that the EU has done the opposite, and is encouraging the use of DDT officially, not blocking its use at all. If DDT is used to fight malaria and not in uncontrolled agricultural use simply to keep products blemish-free, in carefully-controlled sprayings, EU has no complaints.

Is there any western news agency with a stringer in Kampala who could chase this story down? Beck and Reynolds still offer no evidence to back their odd claims, but the story could sure benefit from a solid chunk of reporting from BBC, or Reuters, or Agence France Presse, or someone who could talk with the EU and Uganda officials.

Instapundit screws up again (Uganda, cotton, DDT)

July 5, 2008

Instapundit loves to roil waters, but he’s low on content, and everytime I see it, low on accuracy, too.

This is the entirety of Glenn Beck’sReynolds’s post linking to the rabidly anti-Rachel Carson, RWDB with a rant about DDT that lacks several key points of accuracy:

THE HIGH COST OF fighting malaria.

Six words and he’s wrong already. That’s quite a skill to be dead wrong in six words.

Our friend, Mr. Beck, at RWDB, has a news report from Uganda, and rather than note it and check for accuracy, he uses it as a tee for numerous shots and mulligans against science, scientists, environmentalists, health care workers, the EU, and anyone else who inhabited his latest delerium.

The story out of Africa is that a buyer of organic cotton refused to buy Ugandan cotton due to DDT contamination. True to the line of recent events, it’s not environmentalists who do anything , though the news story finds a way to blame them in the last paragraph. Instead, it’s a businessman.

But here are problems with the story:

  • There is no indication EU has anything to do with this failed purchase.
  • There is no indication that any environmentalist ever played a role — this is a Dutch purchasing company, shopping for organic cotton.
  • There is no indication that Uganda farmers can’t sell their cotton to other buyers.
  • There is no reason to presume that the cotton must be sold as “organic.”
  • There appears to be no indication of any DDT contamination.
  • It’s illegal to spray DDT on cotton in Uganda, as I understand it — if this cotton is contaminated, the problem is that DDT was diverted from malaria control. That’s not a problem for environmentalists — and, according to the PAN story cited above, farmers have incentives to keep it from happening.

Are we to believe that marauding anti-insect people roam Uganda, forcing farmers to steal DDT from health authorities and spray it on their cotton instead, against the farmer’s better interests?

Neither Glenn BeckReynolds at Instapundit nor the other Beck at RWDB bothered to check the facts, nor even to see whether the first face story passes the smell test. Where would DDT contamination come from? Why would a buyer refuse cotton if there’s no DDT contaminant? Why wouldn’t there be tests? Where are the test results? If EU is so down on DDT on cotton, where is the document that says so?

The company in the news story, ineptly named as it is, Bo-Weevil, does exist, it appears, either there or in the Netherlands. That surely is not the only cotton buyer for the EU. The first BoWeevil isn’t an EU company, since it’s headquartered in Tennessee. From their website:

Welcome to Bo-Weevil Eco Sportswear Mfg. LLC., nestled in the hills of Tazewell, Tennessee.

Producers of the most earth friendly clothing on the planet.

Bo-Weevil Eco started manufacturing and supplying clothing with one main vision: “Provide our customers with the highest quality clothing that integrates current fashions with timeless style, to create lifestyle clothing that brings awareness to care what you wear.”

We are a company that practices to restore, maintain and enhance ecological harmony. Doing so by being at the forefront of U.S.A. factories producing a line of women’s, men’s, kids and k-9 apparel made by pre-consumer recycled fibres. We are working to create change in the textile industry; to offer one step on the path to more sensible and sustainable use of resources in the production of basic commodities.

So, how does the EU get into this story at all? The second company, I can find listed only through a post at Pesticide Action Network, a source that is not always reliable on such issues.

Smell test: Does this sound accurate to you? When was the last time you saw anyone at Wal-Mart demand organic cotton?

The use of DDT has now affected cotton prices in the region. Patrick Oryang from Lango Cooperative told All Africa, “We are buying cotton at sh500 per kilogram instead of sh750. The country will lose about US$20 million because EUREP-GAP, an EU exporters body, has suspended buying products from the region because the consumers in Europe and America want purely organic products.”

What’s the real story?

Neither Beck nor Reynolds seems to care. They get a dig at environmentalists, so what if Ugandans get malaria?

Update, sorta: News from Uganda, in New Vision, seems to indicate that the EU has okayed the wise use of DDT in Uganda, contrary to claims of an EU ban (July 10 story). You can’t help but wish there were some good, clear reporting of this issue, from BBC or Reuters, or someone in Kampala besides these few, shallow news dailies.


USAID allows DDT use in Africa

June 25, 2008

Africa Science News Service reports that USAID signed a contract that allows U.S. money to be used to purchase DDT for Indoor Residual Spraying (IRS) against malaria-carrying mosquitoes.

If so, this is one of the final barriers to use of U.S. funds for DDT use. Oddly, the news report offers no details on when or where the contract was made.

DDT use in Uganda was halted pending a suit by Uganda agricultural businesses to stop the spraying. The contract discussed would allow purchase of other insecticides to be used in place of DDT for IRS.

It’s important to note that no environmental organizations have expressed opposition to the limited use of DDT in IRS applications. It may be significant to note that the programs involving indoor spraying fall into the category of integrated pest management, which is what Rachel Carson urged in her 1962 book, Silent Spring.


Symposium in a book: Rachel Carson’s legacy

June 25, 2008

Oklahoma Sen. Tom Coburn released his hold, Rep. Jason Altmire’s bill moved, and three weeks ago the post office in Springdale, Pennyslvania, was named in Rachel Carson’s honor. On the internet, yahoos still try to blame her deaths from malaria, claiming that her message of stewardship was misplaced, and led to a “ban” on DDT that allows malaria to run wild.

Off the internet, serious scholars still work. SUNY Press published a compilation of lectures at Oregon State Univesrity commemorating the 40th anniversary of Carson’s most famous book, Silent Spring. The new book, Rachel Carson: Legacy and Challenge is edited by Lisa Sideris and Kathleen Dean Moore.

Mosquitoes eat DDT, and here’s how

June 18, 2008

University of Illinois researchers found the protein that allows mosquitoes to metabolize DDT.

It’s good news in mosquito research, and may someday provide some insight into how to kill mosquitoes that seem to be resistant to DDT.

But, for all those DDT advocates out there, isn’t this rather embarrassing? Here these researchers have discovered the molecular level mechanisms for a process that the DDT apologists claim doesn’t happen. Oops. Rachel Carson proven right, once again.

There they are, caught red- and bumpy-handed.

Friends of Rachel Carson win a quiet victory

June 13, 2008

How quiet?

None of my news readers pulled it up, either last August and September, when U.S. Rep. Jason Altmire, D-Penn., got the bill through Congress and signed into law by President Bush, nor a couple of weeks ago when the action occurred.

The Post Office in Rachel Carson’s home town, Springdale, Pennsylvania, has been named in her honor. The ceremony at the Post Office was held on May 27, 2008.

Rep. Rob Bishop’s, R-Utah, incendiary and inaccurate statement on the bill was what caught my eye originally about the continuing campaign of calumny against the author and scientist.

Rep. Altmire conducted a petition campaign in Pennsylvania, and used the lever of popular, bipartisan support to pry the bill loose from U.S. Sen. Tom Coburn’s hold in the Senate. Coburn is a Republican from Oklahoma, a physician, and an ardent advocate of spraying DDT. He had placed a hold on the bill in committee, stopping all action under the Senate’s rules of profound deference to members.

The swell of popular support made clear by Altmire’s campaign appears to have persuaded Sen. Coburn to allow the bill to move. The bill passed the Senate by unanimous consent on August 3, 2007, and got President Bush’s signature on August 9. These sorts of honorary bills generally are not targeted for political points. That Coburn allowed the bill through suggests a good deal of maturation as a senator on Coburn’s part.

Below the fold, Rep. Altmire’s press releases on the bill’s passing the Senate, and on President Bush’s signing the bill.

Alma Conference statement pending: Don’t ease DDT restrictions

June 11, 2008

Here is the press release, from Alma College in Alma, Michigan:

Continued Use of DDT Is a Global Health Concern

Scholars who attended the Eugene Kenaga International DDT Conference on Health and the Environment at Alma College are drafting a consensus statement urging global policymakers to reconsider the future use of the synthetic pesticide DDT.

The scholars acknowledge that the use of DDT has prevented millions of infections and deaths from insect-borne diseases, especially malaria. Yet, substantial exposure to DDT poses serious health risks for human populations and the environment, says Edward Lorenz, director of the Public Affairs Institute at Alma College.

“The consensus of the scholars was a recognition of the serious impediments to further restricting DDT use, given that several million people die each year from malaria, most of whom are under the age of five,” says Lorenz. “However, these scholars have documented in numerous human health studies what can be called a ‘deepening understanding of the effects of DDT use on humans.’ The collective wisdom of the experts at the Kenaga Conference was that world policymakers need to use extreme caution when considering easing restrictions on DDT use.”

The March 14 conference attracted international experts in the areas of public health and the environment, including South African scholars Riana Bornman, Henk Bouwman and Christiaan de Jager; Aimin Chen of Creighton University; Barbara Cohn and Brenda Eskenazi of the University of California at Berkeley; Henry Anderson of the Wisconsin Division of Public Health; Suzanne Snedeker of Cornell University; Diane Henshel of Indiana University; Darwin Stapleton of the Rockefeller Archives; Lorenz and John Leipzig of Alma College; and Felicia Leipzig of the Pine River Superfund Citizen Task Force.

The anticipated DDT conference “consensus statement” is expected to list the following summary statements and recommendations, says Lorenz:

  • Repeated use of DDT results in serious health risks for humans.
  • Many sites of chemical-manufacturing facilities continue to be a source of DDT contamination to area residents. While clean-up efforts continue, some DDT proponents, such as John Tierney (New York Times, June 5, 2007), have claimed that, “the billions spent cleaning up Superfund sites would be better spent on more serious dangers.”

“The experts at the DDT Conference unanimously disagree with Tierney’s assessment,” says Lorenz. “Because of the known DDT impacts on human health, the experts not only support continued Superfund clean up, but also endorse assessment of health impacts on residents of communities with DDT sites, such as St. Louis, Mich.”

  • Children and pregnant women in malaria endemic areas where DDT is used are most at risk.
  • Studies have shown that DDT impedes breast milk production, the best source of infant nutrition in many parts of the world.

“Because of the negative impacts on breastfeeding, resulting in more low birth weight babies, communities potentially exposed to DDT to control malaria must be told that the short-term benefits of DDT may spawn longer-term problems,” says Felicia Leipzig.

  • New methods of malaria control should be encouraged and tested.

“Those who are lobbying for DDT use should focus on support for research into alternative chemicals and public health strategies that ultimately will allow for the full phase-out of DDT,” says John Leipzig, director of Alma’s Center for Responsible Leadership.

  • The socio-economic development of malaria-affected communities is the best solution to malaria eradication.
  • Conference experts call for “full support for the Stockholm Convention that will phase out the use of the 12 most dangerous persistent organic pollutants, including DDT,” says Lorenz.

“The Stockholm Convention mandates that each country using DDT have an implementation and management plan on controlling the use of DDT,” he says. “Ultimately it envisions eventual reliance on sustainable methods of disease vector control.”

The scholars argue that sufficient evidence exists that DDT exposure is occurring and posing significant health risks.

“Because of both DDT related Superfund sites and continued use of DDT, exposure to the pesticide is occurring around the world with significant health risks to current and future generations,” says Lorenz.

“The conference experts are challenging policy makers to provide support to further determine health risks associated with DDT exposure in both the developing world and in U.S. communities near contaminated Superfund sites,” he says. “The experts were especially critical of special interests groups and their lobbyists who negate the clear evidence of human health dangers of DDT exposure.”
