Toxic Substances Control Act of 1976 –
Thousands of chemicals and their compounds are developed each year with unknown toxic or dangerous characteristics. The Toxic Substances Control Act (TSCA, pronounced TOS-cah) requires the EPA to test, screen and regulate all chemicals produced or imported into the United States. To prevent tragic consequences, TSCA requires that any chemical that reaches the consumer marketplace be tested for possible effects to human health and the environment prior to commenrcial manufacture.
