International Chemical Safety Cards

An ICSC summarizes essential health and safety information on chemicals for their use at the "shop floor" level by workers and employers in factories, agriculture, construction and other work places.

CHEMID"  info

ChemIDplus is a free, web-based search system that provides access to structure and nomenclature authority files used for the identification of chemical substances cited in National Library of Medicine (NLM) databases. ChemIDplus also provides structure searching and direct links to many biomedical resources at NLM and on the Internet for chemicals of interest. The database contains over 400,000 chemical records, of which over 300,000 include chemical structures, and is searchable by Name, Synonym, CAS Registry Number, Molecular Formula, Classification Code, Locator Code, and Structure.


EXTOXNET is a cooperative effort of University of California-Davis, Oregon State University, Michigan State University, Cornell University, and the University of Idaho. Primary files are maintained and archived at Oregon State University.

GENETOX"  info

Peer-reviewed mutagenicity test data from the Environmental Protection Agency (EPA).

Household Products Database

Excellent structed database, made by the Natinal Library of Medicine, NLM.

Hazardous Substances Data Bank"  info

HSDB (Hazardous Substances Data Bank) is a scientifically reviewed, factual database containing records for about 4500 toxic chemicals. It contains extensive information in areas as toxicity, environmental fate, human exposure, chemical safety, waste disposal, emergency handling, and regulatory requirements.

Immediately Dangerous to Life or Health Concentration

Toxic concentrations of chemicals.

Chemical Safety Information from Intergovernmental Organizations

IPCS INCHEM is a means of rapid access to internationally peer reviewed information on chemicals commonly used throughout the world, which may also occur as contaminants in the environment and food.

Integrated Risk Information System"  info

Integrated Risk Information System - data from the EPA in support of human health risk assessment, focusing on hazard identification and dose-response assessment.

International Toxicity Estimates

A product of the Cincinnati based Toxicology Excellence for Risk Assessment, ITER presents chemical risk information from authoritative groups worldwide, including the U.S. Environmental Protection Agency, the U.S. Agency for Toxic Substances and Disease Registry, Health Canada, the Dutch National Institute of Public Health and the Environment, the International Agency for Research on Cancer, as well as independent parties whose risk values have undergone peer review.

Nuclide Safety Data Sheets

Nuclide Safety Data Sheets provided by the North Carolina State University.

Radionuclide Safety Data Sheets

Informations about radionuclides.

Toxicological Profile Information Sheets

The Toxicological Profile Information Sheets are produced by the Agency for Toxic Substances and Disease Registry (ATSDR).


TOXNET is a cluster of databases on toxicology, hazardous chemicals, and related areas. Provided by the NLM, National Library of Medicine:

  • HSDB - Hazardous Substances Data Bank
  • IRIS - Integrated Risk Information System
  • ITER - International Toxicity Estimates for Risk
  • GENE-TOX - Genetic Toxicology (Mutagenicity)
  • CCRIS - Chemical Carcinogenesis Research Information System
  • TOXLINE - Toxicology Bibliographic Information
  • DART - Developmental & Reproductive Toxicology
  • TRI - Toxics Release Inventory
  • ChemIDplus - Chemical Synonymes, Structures and more

  • Toxics Release Inventory"  info

    TRI contains data on the estimated annual releases of toxic chemicals to the environment air, water, soil, underground injection; amounts transferred off-site for waste treatment; and source reduction and recycling data.
    This is a NLM-database.
