EPA Puts Five Common Chemicals under Close Scrutiny

The U.S. Environmental Protection Agency (EPA) recently released the first draft risk assessments developed under the Toxic Substances Control Act (TSCA) Work Plan.
In 2012, the EPA announced it would prepare risk assessments on 83 priority chemicals. The draft risk assessments are for particular uses of five of these chemicals found in household products: methylene chloride or dichloromethane (DCM) and N-methylpyrrolidone (NMP) in paint stripper products; trichloroethylene (TCE) as a degreaser and a spray-on protective coating; antimony trioxide (ATO) as a synergist in halogenated flame retardants; and 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8,-hexamethylcyclopenta-[?]-2-benzopyran (HHCB) as a fragrance ingredient.

The draft assessments focus on human health or ecological hazards for uses that are subject to TSCA regulation. Three of the draft risk assessments — for DCM, NMP and TCE — indicate a potential concern for human health under specific exposure scenarios. The draft assessments for ATO and HHCB indicate a low concern for ecological risks.
