All data are from a core set of books, government documents, technical reports, selected primary journal literature, and other online sources of information, with a goal of linking the HSDB content to as much publicly available information as possible.
HSDB has approximately 5,600 chemicals and substances, with a focus on toxicology information and also on human exposure, industrial hygiene, emergency handling procedures, environmental fate, regulatory requirements, and related areas of likely interest to HSDB users. Like the rest of TOXNET’s databases and other resources, HSDB is available online at no cost to global users. HSDB, a part of NLM’s Toxicology Data Network (TOXNET ®), is a file of chemical/substance information with one record for each specific chemical or substance, or for a category of chemicals or substances. The National Library of Medicine’s (NLM) Division of Specialized Information Services (SIS) Toxicology and Environmental Health Information Program is responsible for the management of the online Hazardous Substances Data Bank (HSDB).
