Environmental Protection Agency (EPA) ToxCast program and have been used to screen >3500 compounds, of which a significant portion are also part of the multi-agency Tox21 program. This extensive database presumably enables these platforms to help narrow the number of compounds potentially responsible for toxicity in a complex mixture. As a first pass, we compared the results of the bioassays to those available on the U.S EPA CompTox dashboard for compounds reported to occur in PCL formulations and those tentatively identified by GC×GC in the consumer-grade PCL.
