(Beyond Pesticides, September 19, 2007) In Vietnam, attempts continue to be made to protect villages from the ongoing threat of Agent Orange, used by American forces to deforest the jungle canopy in the Vietnam War over 30 years ago, according to the New York Times. Reforestation and fencing are being carried out to prevent local animals and residents from being exposed to soil contaminated with 2,3,7,8-Tetrachlorodibenzo-p-Dioxin (TCDD), a potent dioxin contaminant of Agent Orange. Phung Tuu Boi, forester and director of the Center for Assistance in Nature Conservation and Community Development in Hanoi, is attempting to reforest thousands of hectares in central Vietnam. However, his main concern is the dioxin that taints the soil and the local residents most at risk since they live off the land. “The local people are poor and uneducated, and they don’t understand. Children come here to play and they collect insects and other things to eat,” said Mr. Boi. TCDD is the most dangerous form of dioxin and the levels found in soil samples from Central Vietnam are more than 200 times the “acceptable” level set by the US EPA. Efforts to educate the residents about the dangers of dioxin are difficult since most […]

(Beyond Pesticides, August 16, 2007) The Environmental Protection Agency’s (EPA) recent decision not to go through with a Special Review of 2,4-D’s carcinogenic properties is being touted by industry as the final word that the toxic chemical “has been found to have no human carcinogenic effects,” despite significant evidence to the contrary. The Special Review has been cancelled after an industry task force poured millions of dollars into industry funded research and a public relations campaign. The pesticide 2,4-D, or 2,4-Dichlorophenoxyacetic acid, was first slated by EPA for Special Review in 1986. A few years later in a unique move, several large pesticides companies with a common interest in keeping 2,4-D on the market formed the Industry Task Force II on 2,4-D Research Data. Since then, the task force reports it has funded nearly $30 million in new research on the chemical. Industry funded research is often biased and influential in the regulatory process. The results are reported to EPA, which provides a large portion of the data the agency relies on in order to make decisions under an inadequate risk assessment review process. The task force is currently comprised of the major pesticide producers Dow AgroSciences (U.S.), Nufarm Ltd. […]

(Beyond Pesticides, August 14, 2007) In an August 8, 2007 Federal Register Notice (72 FR 44510-44511), the Environmental Protection Agency (EPA) announced its decision to not initiate a Special Review for the commonly used herbicide 2,4-D, as well as the related herbicides 2,4-DB and 2,4-DP (dichlorprop). Despite evidence to the contrary, according to the FR notice, “Based on extensive scientific review of many epidemiology and animal studies, EPA find that the weight of the evidence does not support a conclusion that 2,4-D, 2,4-DB and 2,4-DP are likely human carcinogens.” Although a mounting body of evidence links 2,4-D to various cancers, particularly non-Hodgkin’s lymphoma, EPA has been reluctant to classify it as a carcinogen in the face of industry pressure. EPA lists the herbicide in class D for carcinogenicity. Chemicals in this class are considered to have inadequate evidence for carcinogenicity, or not enough data is available. However, the link between 2,4-D and non-Hodgkin’s lymphoma has been demonstrated in the United States, Italy, Canada, Denmark, and Sweden. A 1986 National Cancer Institute (NCI) study found that farmers in Kansas exposed to 2,4-D for 20 or more days per year had a six-fold higher risk of developing non-Hodgkin’s lymphoma than non-farmers. The […]
