The Hazardous Substances Data Bank (HSDB) is a toxicology database on the U.S. National Library of Medicine's (NLM) Toxicology Data Network (TOXNET).[2][3] It focuses on the toxicology of potentially hazardous chemicals, and includes information on human exposure, industrial hygiene, emergency handling procedures, environmental fate, regulatory requirements, and related areas. All data are referenced and derived from a core set of books, government documents, technical reports, and selected primary journal literature. All entries are peer-reviewed by a Scientific Review Panel (SRP), members of which represent a spectrum of professions and interests. Current Chairs of the SRP are Dr. Marcel J. Cassavant, MD, Toxicology Group, and Dr. Roland Everett Langford, PhD, Environmental Fate Group.

The HSDB is organized into individual chemical records, and contains over 5000 such records.[4] It is accessible free of charge via TOXNET. Users can search by chemical or other name, chemical name fragment, CAS registry number and/or subject terms. Recent additions include radioactive materials and certain mixtures, like crude oil and oil dispersants as well as animal toxins. As of November 2014, there are approximately 5,600 chemical specific HSDB records available.[3]

TOXNET databases[edit]

The Toxicology Data Network (TOXNET) is a group of databases hosted on the National Library of Medicine (NLM) website that covers "chemicals and drugs, diseases and the environment, environmental health, occupational safety and health, poisoning, risk assessment and regulations, and toxicology".[5] TOXNET is managed by the NLM's Toxicology and Environmental Health Information Program (TEHIP) in the Division of Specialized Information Services (SIS).[5]

The TOXNET databases include:[6]

  1. HSDB: Hazardous Substances Data Bank
    • Peer-reviewed toxicology data for over 5,000 hazardous chemicals
    • 4 million references to literature on biochemical, pharmacological, physiological, and toxicological effects of drugs and other chemicals
  3. ChemIDplus
    • Dictionary of over 400,000 chemicals (names, synonyms, and structures)
  4. LactMed: Drugs and Lactation Database
    • Drugs and other chemicals to which breastfeeding mothers may be exposed
  5. DART: Developmental and Reproductive Toxicology Database
    • References to developmental and reproductive toxicology literature
    • Environmental Health Maps provides searchable, interactive maps of EPA TRI and Superfund data, plus US Census and NCI health data
  7. TRI: Toxics Release Inventory
    • Annual environmental releases of over 600 toxic chemicals by U.S. facilities
  8. CTD: Comparative Toxicogenomics Database
    • Access to scientific data describing relationships between chemicals, genes and human diseases
  9. Household Products Database
    • Potential health effects of chemicals in more than 10,000 common household products
  10. Haz-Map
    • Links jobs and hazardous tasks with occupational diseases and their symptoms
  11. IRIS: Integrated Risk Information System
    • Hazard identification and dose-response assessment for over 500 chemicals
  12. ITER: International Toxicity Estimates for Risk
    • Risk information for over 600 chemicals from authoritative groups worldwide
  13. ALTBIB
    • Resources on Alternatives to the Use of Live Vertebrates in Biomedical Research and Testing
