As part of its continued effort to produce health hazard assessments for substances listed in the Toxic Substances Control Act (TSCA) Work Plan, the US EPA has released problem formulation and initial assessment documents on three classes of flame retardants (chlorinated phosphate esters, cyclic aliphatic bromides, and tetrabromobisphenol A and its esters). The goal of these documents is to identify scenarios where further work is required to fully characterise the substances’ risk to human health and the environment.
