Computational Toxicology Research Program


ACToR is one of many EPA tools available for those interested in chemical toxicity to find data about potential chemical risks to human health and the environment. The data warehouse:

  • Is a collection of databases collated or developed by the US EPA Computational Toxicology Research Program.
  • Aggregates data from over 500 public sources on over 500,000 environmental chemicals searchable by chemical name, other identifiers, and by chemical structure.
  • Data includes chemical structure, physico-chemical values, in vitro assay data and in vivo toxicology data.

  • Chemicals include, but are not limited to, high and medium production volume industrial chemicals, pesticides (active and inert ingredients), and potential ground and drinking water contaminants.
  • Provides a connection to another EPA chemical screening tool called ToxCast, a multi-year, multi-million dollar effort that uses advanced science tools to help efficiently understand biological processes impacted by chemicals that may lead to adverse health effects.
