The Precautionary Approach and the International Control of Toxic Chemicals: Beacon of Hope, Sea of Confusion and Dilution
Toxic chemicals in the environment are a continuing concern. Nearly 80,000 chemicals are on the market in the United States; of those, 200 synthetic chemicals are found in measurable quantities in the bodies of Americans. More than 5 billion kilograms of toxic pollutants are released or transferred...

Toxic chemicals in the environment are a continuing concern. Nearly 80,000 chemicals are on the market in the United States; of those, 200 synthetic chemicals are found in measurable quantities in the bodies of Americans. More than 5 billion kilograms of toxic pollutants are released or transferred each year in North America. Even more alarming, basic toxicological information is lacking for most these chemicals. Long-range transport of persistent organic pollutants (POPs), chemicals that are persistent and bioaccumulate, is a special concern particularly in the Arctic, which acts as a "sink." Examples of POPs include various pesticides, such as DDT, chlordane, aldrin, heptachlor and toxaphene, industrial chemicals such as PCBs (polychlorinated biphenyls), and unintentional byproducts such as dioxins and furans.
