Methylene Chloride Poses Cancer, Other Health Risks, EPA Says

Written by

Methylene chloride is a volatile organic compound widely used as a solvent in numerous applications, including adhesives, pharmaceuticals, metal degreasers, chemical processes, and aerosols, as well as paint strippers. EPA classifies the chemical as “likely to be carcinogenic in humans.”

EPA is considering voluntary and regulatory actions to reduce the risks to workers and consumers from exposure to methylene chloride. The agency says it plans to meet with stakeholders and the public to determine potential alternatives to DCM in paint strippers and other ways to reduce exposure to the chemical.

Also on Aug. 28, EPA released assessments for two other chemicals—antimony trioxide, used in halogenated flame retardants, and 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[γ]-2-benzopyran (HHCB), a fragrance ingredient. The agency did not identify any significant ecological risks with either substance. EPA says it did not examine the human health risks of either of the chemicals because the agency determined that such risks are likely to be low.

The just-released assessments are three of dozens expected to be released under an EPA effort to review the safety of 83 chemicals under the Toxic Substances Control Act. The results could lead EPA to ban, restrict, or require labeling of the chemicals or declare them safe for current uses.
