Completed Risk Assessments

Completed Problem Formulation and Initial Assessments

  • Brominated Phthalate Cluster: On August 13, 2015, EPA released a data needs assessment for the Brominated Phthalate Cluster used as flame retardants in polyurethane foams.  During problem formulation, EPA/OPPT reviewed previous assessments and identified critical gaps in toxicity, exposure, and commercial mixtures data. The data needs assessment is intended to guide the collection of additional data and information. Chemical in bold is on EPA’s 2014 TSCA Work Plan.
  • Chlorinated Phosphate Esters Cluster: On August 13, 2015, EPA released a problem formulation for Chlorinated Phosphate Esters used as flame retardants in furniture foams and textiles. The goal of this problem formulation was to identify scenarios where further risk analysis may be necessary. The conclusion of this problem formulation is that EPA will assess risks to consumers, the general population and aquatic organisms exposed as a result of manufacture, processing and use of chlorinated phosphate esters cluster members.
