Related Topics: Toxic Substances Control Act (TSCA) US Environmental Protection Agency
EPA today released final risk assessments on three TSCA Work Plan Chemicals -- Methylene Chloride or Dichloromethane (DCM), Antimony Trioxide (ATO), and 1,3,4,6,7,8-Hexahydro-4,6,6,7,8,8,-hexamethylcyclopenta[γ]-2-benzopyran (HHCB).
The DCM risk assessment addresses paint stripper products. The final risk assessment indicates health risks to both workers and consumers who use these products, and to bystanders in workplaces and residences where DCM is used. EPA is considering a range of possible voluntary and regulatory actions to address concerns and anticipates conducting a workshop in late fall to engage key stakeholders and the public on potential alternatives and risk reduction approaches.
The ATO risk assessment addresses effects on ecological receptors from the use of antimony trioxide (ATO) as a synergist in halogenated flame retardants. EPA’s final risk assessment indicates no concern for this use of ATO.
The HHCB risk assessment addresses ecological risks from HHCB as a fragrance ingredient in commercial and consumer products. EPA’s final risk assessment indicates no concern for this use of HHCB.
