TOXNET: From exposure standards to toxic releases, answers to your environmental health questions

Stacey J. Arnesen, MS, Martha Szczur, and George Hazard, PhD. Specialized Information Services, National Library of Medicine, 6707 Democracy Blvd., Suite 510, Bethesda, MD 20892, 301-496-2971,

The most widely recognized of NLMs TEHIP resources is TOXNET, a network of toxicology and environmental health databases ( TOXNET, originally developed in the 1980s, has undergone many modifications to keep pace with technology. Today, TOXNET is available for free on the web and features an integrated system allowing users to search nine TOXNET databases simultaneously. This presentation will describe the use of all TOXNET databases, but will highlight the three most heavily used: Hazardous Substances Data Bank (HSDB), TOXicology Literature Online (TOXLINE), and Chemical Identification database (ChemIDplus). HSDB is an online handbook containing peer-reviewed information on over 4,500 chemicals including health effects, standards and regulations, human exposure, safety, and environmental fate data. Data are extracted from the published literature including handbooks, monographs, technical reports, and the primary literature. TOXLINE is a bibliographic database containing 3 million references and abstracts from the scientific literature published since the 1960s. TOXLINE is separated into two components: TOXLINE Core, for references from the toxicology subset of MEDLINE/PubMed (scientific journal literature) and TOXLINE Special for references to reports, books, abstracts, research projects, and archival collections in toxicology and environmental health. ChemIDplus serves as the backbone for all of NLMs environmental health databases by providing synonyms and Chemical Abstracts Services Registry Numbers for over 350,000 chemicals and structures for over 100,000 chemicals. Locator links allow immediate searching of other databases, including non-NLM databases, for information about a given chemical. The use of the TOXNET databases for locating information on public health issues will be demonstrated.
