Additional EPA toxicity information may be available by visiting the following sites, including the following:
  • Human Health Benchmarks for Pesticides (HHBP) information. The HHBP website provides toxicity reference values for a number of pesticides to help determine if there is a potential health risk when pesticides are detected in water. However, the toxicity information from the HHBP table may be useful for other purposes.
  • EPA Pesticide Program toxicity information. This link provides information from EPA's Pesticide Program on the derivation of toxicity reference values.
  • EPA's Chemistry Dashboard. This link provides information from EPA's National Center for Computational Toxicology (NCCT) on chemical structures, experimental and predicted physicochemical and toxicity data, and additional links to relevant websites and applications.
