The Toxic Substances Control Act (TSCA) is a United States law enacted in 1976 that regulates the introduction of new or already existing chemicals. It grants the Environmental Protection Agency (EPA) authority to require reporting, record-keeping, and testing requirements for chemical substances, ensuring that potentially hazardous substances are managed appropriately. This act is particularly relevant for nanomaterials, as their unique properties may pose different risks compared to their larger counterparts.
