EPA Advances Review of Four Chemicals, Seeks Public and Expert Input on Health Risks
The Environmental Protection Agency (EPA) is moving forward with its review of four chemicals under the Toxic Substances Control Act (TSCA): 1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8-hexamethylcyclopenta [g]-2-benzopyran (HHCB), phthalic anhydride, o-dichlorobenzene (oDCB), and p-dichlorobenzene (pDCB). The agency has released draft documents for public comment and independent scientific peer review by the Science Advisory Committee on Chemicals (SACC). These chemicals are commonly found in various products, including fragrances, paints, coatings, cleaners, and industrial processes. The EPA's draft risk evaluation for HHCB, a fragrance ingredient, indicates no unreasonable risk under current law across 22 conditions of use. However, for phthalic anhydride, used in paints and plastics, the draft evaluation identifies unreasonable risks to workers and consumers from dermal and inhalation exposure. For pDCB and oDCB, used in manufacturing and cleaning, draft hazard assessments confirm serious non-cancer health concer...
