The U.S. Environmental Protection Agency’s (EPA) ToxCast chemical screening program has awarded contracts to four United States-based companies to test up to 10,000 chemicals for potential toxicity to people and the environment. ToxCast is designed to determine how chemical exposures affect human health. When fully implemented, ToxCast will be able to screen thousands of chemicals in fast, cost-effective tests.
The chemicals ToxCast is now screening are found in industrial and consumer products, food additives and drugs. ToxCast’s goal is to reduce EPA’s reliance on slow and expensive animal toxicity tests, enabling the agency to screen chemicals more quickly and to predict and identify potential risks to Americans.
