The Environmental Protection Agency (EPA) has designated five chemicals as High-Priority Substances for risk evaluation under the Toxic Substances Control Act (TSCA). This designation means these chemicals may pose an unreasonable risk to health or the environment, prompting further investigation and evaluation. The five chemicals identified are acetaldehyde, acrylonitrile, benzenamine, vinyl chloride, and 4,4β²-methylene bis(2-chloroaniline) (MBOCA). EPA's decision follows a public consultation process, during which it received thousands of comments and additional information from the public and various organizations.
Simple Explanation
The EPA, which helps keep the environment healthy, is going to check five chemicals to see if they are dangerous, like having a toy checked to make sure it's safe to play with. They're doing this because some people think these chemicals might cause problems, just like how a watchful adult makes sure everyone is safe during playtime.
