EPA’s Risk Assessment for DCM Indicates Health Risks to Workers, Consumers

EPA’s final risk assessment for dichloromethane (DCM), or methylene chloride, indicates health risks to both workers and consumers who use products containing DCM. EPA estimates that more than 230,000 U.S. workers are exposed to DCM from paint-stripping products containing the chemical. According to the agency’s press release, EPA has begun considering a variety of potential voluntary and regulatory actions to address concerns regarding DCM.

Two more final risk assessments released by EPA did not indicate concerns. One examined the ecological risks of antimony trioxide (ATO) used as a synergist in halogenated flame retardants and the other examined 1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8,-hexamethylcyclopenta-[ã]-2-benzopyran (HHCB) used as a fragrance ingredient in commercial and consumer products.
These risk assessments were developed as a part of EPA’s Toxic Substances Control Act (TSCA) Work Plan, which identified chemicals for review and assessment of potential risks to human health and the environment.
