Fact Sheet
Hazardous Substances Data Bank (HSDB®)

HSDB is a toxicology data file on the National Library of Medicine's (NLM) Toxicology Data Network (TOXNET®). It focuses on the toxicology of potentially hazardous chemicals. It is enhanced with information on human exposure, industrial hygiene, emergency handling procedures, environmental fate, regulatory requirements, nanomaterials, and related areas. All data are referenced and derived from a core set of books, government documents, technical reports and selected primary journal literature. HSDB is peer-reviewed by the Scientific Review Panel (SRP), a committee of experts in the major subject areas within the data bank's scope. HSDB is organized into individual chemical records, and contains over 5000 such records.

Web Access/Searching

HSDB is accessible, free of charge, via TOXNET at: http://toxnet.nlm.nih.gov

Users can search by chemical or other name, chemical name fragment, Chemical Abstracts Service Registry Number (RN), and/or subject terms. Search results can easily be viewed, printed or downloaded. Search results are displayed in relevancy ranked order. Users may select to display exact term matches, complete records, or any combination of data from the following broad groupings:

Human Health Effects
Emergency Medical Treatment
Animal Toxicity Studies
Metabolism/Pharmacokinetics
Pharmacology
Environmental Fate/Exposure
Environmental Standards & Regulations
Chemical/Physical Properties
Chemical Safety & Handling
Occupational Exposure Standards
Manufacturing/Use Information
Laboratory Methods
Special References
Synonyms and Identifiers
Administrative Information

Users can easily conduct their HSDB search strategy against other databases: Chemical Carcinogenesis Research Information System, Integrated Risk Information System, and GENE-TOX.

HSDB Review Status Tags

Associated with each data statement in HSDB is one of the following review status tags indicating the level of quality review: "Peer Reviewed" - representing data which has undergone peer review by the Scientific Review Panel or other high level review group, "QC Reviewed" - representing data which has received a quality control review, but not yet been reviewed by the Scientific Review Panel, "Unreviewed" - used for a limited number of data statements, such as industry submissions, which do not readily lend themselves to scientific review.
