What are PCBs and what effects might they have on health and the environment?
PCBs have been demonstrated to cause a variety of adverse health effects. PCBs have been shown to cause cancer in animals. PCBs have also been shown to cause a number of serious non-cancer health effects in animals, including effects on the immune system, reproductive system, nervous system, endocrine system and other health effects. Studies in humans provide supportive evidence for potential carcinogenic and non-carcinogenic effects of PCBs. The different health effects of PCBs may be interrelated, as alterations in one system may have significant implications for the other systems of the body.

Another resource is the Toxic Substances Control Act (TSCA) Hotline. Please note that as of October 1, 2007, the TSCA Hotline will only answer inquiries regarding the use of PCBs. Inquiries regarding the cleanup and disposal of PCBs and PCB wastes will be forwarded to the Office of Solid Waste for a response.
The Toxic Substances Control Act (TSCA) Assistance Information Service provides technical assistance and information about substances regulated under the act and also provides copies of some TSCA-related publications.
