U.S. Environmental Protection Agency (EPA)

The EPA enforces federal environmental protection laws. It registers and regulates pesticides, enforces laws covering outdoor air and drinking water quality and regulates the disposal of hazardous and solid wastes. EPA's Integrated Risk Information System (IRIS) is an electronic database containing information on health effects that may result from exposure to chemicals. IRIS is intended for those without extensive training in toxicology, but with some knowledge of health sciences.
