Question - What is the EPA’s “ToxCast” initiative?
Answer- The cited resource notes “ToxCast is a multi-year effort launched in 2007 that uses automated chemical screening technologies called high-throughput screening assays to expose living cells, isolated proteins, or other biological molecules to chemicals. The cells or proteins are then screened for changes in biological activity that may suggest potential toxic effects. These innovative methods have the potential to limit the number of required laboratory animal-based toxicity tests while quickly and efficiently screening thousands of chemicals for potential health effects.”( https://www.epa.gov/chemical-research/toxcast-owners-manual-guidance-exploring-data; accessed December 2019)
