Dioxins and furans in the atmosphere
Dioxins have been characterized as likely to be human carcinogens and are
anticipated to increase the risk of cancer at background levels of exposure.
At body burden levels 10 times or less above those attributed to average
background exposure, adverse noncancer health effects have been observed
both in animals and, to a more limited extent, in humans. In animals these
effects include changes in hormone systems, alterations in fetal development,
reduced reproductive capacity, and immunosuppression. Effects specifically
observed in humans include changes in markers of early development and
hormone levels. At much higher doses, dioxins can cause a serious skin
disease in humans called chloracne.
What are the health effects of exposure to dioxins and furans?
Dioxins and furans can cause a number of health effects. The most well known
member of the dioxins/furans family is 2,3,7,8 TCDD.
The U.S. Environmental Protection Agency(EPA) has said that it is likely to be
