EPA Ecotoxicology Knowledgebase (ECOTOX)
EPA’s Ecotoxicology Knowledgebase (ECOTOX) provides public access to comprehensive information on adverse effects of single chemical stressors to ecologically relevant aquatic and terrestrial species. ECOTOX includes curated data compiled from over 54,000 references from the scientific literature and over 1.1 million test records covering nearly 14,000 aquatic and terrestrial species and 13,000 chemicals.
There were eight updates to the ECOTOX during 2022-2023. Recent additions include information on 6-PPD quinone, cyanotoxins, and PFAS. In 2023, the ECOTOX Knowledgebase had over 16,000 average monthly users and over 2,000 new users. An ECOTOX training session presented in February 2023 attracted over 500 participants. Additional training resources for ECOTOX are available on the EPA NAMs Training webpage.
