Waterlife — No matter where we live, the Great Lakes affect us all. And as species of fish disappear and rates of birth defects and cancer rise, it seems one thing is clear: the Great Lakes are changing and something's not quite right with the water.

Bisphenol A: this extremely common chemical leaches out of food packaging and plastics, and was long considered safe. But a number of recent studies link it to developmental problems and cancer in lab animals in doses far lower than the current regulatory limit. Canada and the United States both review the scientific data available in the coming months, but critics already worry the process will be corrupted by industry. Industry, of course, insists that BPA is safe.
Cancer, Chemicals and History. Some of the biggest chemical companies in the US have launched a campaign to discredit two historians who have written a book about the industry's efforts to conceal links between their products and cancer. Some of the internal documents referenced in the book can be found at the Chemical Industry Archives, a site dedicated to exposing the industry's attempts to conceal the dangers of their products.

BodyBurden: the pollution in people. "Researchers at two major laboratories found an average of 91 industrial compounds, pollutants, and other chemicals in the blood and urine of nine volunteers, with a total of 167 chemicals found in the group. Like most of us, the people tested do not work with chemicals on the job and do not live near an industrial facility. Scientists refer to this contamination as a person’s body burden. Of the 167 chemicals found, 76 cause cancer in humans or animals, 94 are toxic to the brain and nervous system, and 79 cause birth defects or abnormal development. The dangers of exposure to these chemicals in combination has never been studied." This was also the subject of a PBS program by Bill Moyers, Trade Secrets. Moyers himself was found to have 84 chemicals in his blood and urine. [Via This Modern World.]
The State of the Nation's Ecosystems - According to a report commissioned five years ago by President Clinton and finally completed and released, the United States may have no streams left that are free from chemical contamination, and about one-fifth of animal species and one-sixth of plant types are at risk of extinction.
