Which chemicals are classified as CERCLA-7 due to their significant human health impact?

Chloroform is classified as one of the CERCLA-7 substances due to its significant impact on human health. The CERCLA (Comprehensive Environmental Response, Compensation, and Liability Act) was established to address hazardous substances that pose a substantial risk to public health and the environment. Chloroform has been identified as a chemical that can cause various health issues, including potential carcinogenic effects, liver toxicity, and other adverse health outcomes when exposed to humans.

The classification of CERCLA-7 encompasses those chemicals that are especially hazardous and require particular attention for risk management and remediation. Although trichloroethylene, lead, and cyanide are also hazardous substances with serious health implications, they may not be part of the specific seven substances designated under CERCLA for their significant human health impacts. It’s important to recognize the implications of these classifications as they guide environmental policy and public health strategies in dealing with hazardous materials.
