Dioxin toxicity research studies show cancer, reproductive risks
Two new studies have found evidence for cancer and reproductive risks from exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD). A study of the effects of the chemical plant explosion that occurred in Seveso, Italy, 17 years ago indicates that exposure to 2,3,7,8-TCDD increases the risk of cancer in humans. This is the first scientific study to show increased cancer rates in people exposed to the dioxin in the accident. In addition, a study by Environmental Protection Agency (EPA) scientists has found that a single low dose of 2,3,7,8-TCDD in pregnant laboratory animals causes reproductive abnormalities in their offspring. The EPA results have not yet been published, but they will be presented this month at a meeting in Vienna. These results and other similar laboratory studies may affect the way EPA writes its protocols for testing pesticides and toxic substances.
