Answer 1

In 1993, the U.S. Environmental Protection Agency (EPA) classified certain chemicals and substances based on their potential hazards to human health and the environment. This classification included assessments of carcinogenicity, toxicity, and ecological impact, aiming to inform regulatory decisions and public awareness. The initiative was part of the EPA's broader mandate to protect air and water quality, as well as to ensure safe management of hazardous waste. Such classifications guide policies and regulations to mitigate risks associated with environmental contaminants.
