U.S. Environmental Protection Agency, Office of Chemical Safety and Pollution Prevention (OCSPP): Chemical Risk Review and Reduction - International Toxic Substances Control Act (TSCA): Test Guidelines Harmonization

This activity allows the U.S. to contribute to and take advantage of harmonized test guidelines among OECD member countries and industry stakeholders avoiding duplication of effort and saving upwards of $11 million annually.

Scientists participate to develop protocols for studies to assess physiochemical properties, environmental fate, exotoxicity, and health toxicity endpoints. The Agency is also updating its master list so that users can access the most current guidelines.
