TOXicology Data NETwork (TOXNET) was a comprehensive resource provided by the United States National Library of Medicine (NLM). It offered access to a wide range of databases related to toxicology, hazardous chemicals, environmental health, and related areas. As of December 16, 2019, TOXNET was retired by the National Library of Medicine and its content was integrated into other NLM resources.
While TOXNET itself has been retired, the information it provided is still accessible through other NLM resources like PubChem, PubMed, and the NLM's website. These resources continue to provide valuable information on toxicology, environmental health, and related topics.
