Many U.S. residents carry toxic pesticides in their bodies above government assessed "acceptable" levels, according to a report released in May by Pesticide Action Network North America (PAN) and the Ecology Center, Lone Tree Council, Michigan Environmental Council and Michigan Organic Food and Farming Alliance.

Chemical Trespass: Pesticides in Our Bodies and Corporate Accountability makes public for the first time an analysis of pesticide-related data collected by the Centers for Disease Control and Prevention (CDC) in a study of levels of chemicals in 9,282 people nationwide. The report reveals that government and industry have failed to safeguard public health from pesticide exposures.

"None of us chooses to have hazardous pesticides in our bodies," said Kristin Schafer, PAN Program Coordinator and lead author of the report. "Yet CDC found pesticides in 100% of the people who had both blood and urine tested. The average person in this group carried a toxic cocktail of 13 of the 23 pesticides we analyzed."

Dr. William Weil, Michigan State University professor emeritus and pediatrician, commented: "There is no longer any doubt that the fetus, the infant, the child and the adolescent are more at risk for serious impairment from most environmental chemical hazards than are adults. It is, therefore, incumbent on the federal and state governments to eliminate these hazards as expeditiously as possible and in the interim to set exposure limits with the additional safety factor in keeping with these vulnerabilities and to support research that can define these limits more accurately when the existing data are inadequate."

Many of the pesticides found in the test subjects have been linked to serious short- and long-term health effects, including infertility, birth defects and childhood and adult cancers. "While the government develops safety levels for each chemical separately, this study shows that in the real world we are exposed to multiple chemicals simultaneously," explained Margaret Reeves, PhD, Senior Scientist at PAN.

Chemical Trespass found that children, women and Mexican Americans shouldered the heaviest "pesticide body burden." For example, children-the population most vulnerable to pesticides-are exposed to the highest levels of nerve-damaging organophosphorous (OP) pesticides. The CDC data show that the average 6- to 11-year-old sampled is exposed to the OP pesticide chlorpyrifos at four times the level U.S. Environmental Protection Agency (EPA) considers "acceptable" for long-term exposure. Chlorpyrifos, produced principally by Dow Chemical Corporation and found in numerous products such as Dursban™, is designed to kill insects by disrupting the nervous system. Although the EPA restricted chlorpyrifos for most residential uses in 2000, it continues to be used widely in agriculture and other settings. In humans, chlorpyrifos is also a nerve poison and has been shown to disrupt hormones and interfere with normal development of the nervous system in laboratory animals.

The report introduces the Pesticide Trespass Index (PTI), a new tool for quantifying responsibility of individual pesticide manufacturers for their "pesticide trespass." Using the PTI, the report estimates that Dow Chemical is responsible for at least 80% of the chlorpyrifos products found in the bodies of those in the U.S.

"Why is it that chemical companies like Dow are not ingenious enough to develop safer alternatives? Where is the celebrated American know-how of our corporations? Where is the can-do attitude to improve products rather than to deny and evade and continue to sell clearly inferior products?" asked Tracey Easthope, MPH, Director of the Environmental Health Project at the Ecology Center.

"The fact that our children carry dangerous pesticides in their bodies represents a dramatic failure in the way our government protects us from toxic pesticides," said Dave Dempsey of MEC. "We must stop this toxic trespass by shifting the burden from our bodies back to the corporate boardroom where it belongs."

Chemical Trespass provides recommendations for government, industry and the public

o Congress should conduct a thorough and independent investigation into corporate responsibility and liability for pesticide body burdens and establish financial mechanisms to shift health and environmental costs of pesticides to the corporations that produce them.

• EPA should ban use of pesticides known to be hazardous and pervasive in the environment and our bodies and should immediately phase out all uses of chlorpyrifos and lindane.
• EPA should require that manufacturers bear the burden of proof for demonstrating that a pesticide does not harm human health before it can be registered and should work with the U.S. Department of Agriculture (USDA) to actively promote least-toxic pest control methods.
• Individuals should pressure government officials and corporations to implement these changes, seek alternatives to pesticide use and buy organic products whenever possible.
