    8. 16. TOXNET: Toxicology & Environmental Information http://toxnet.nlm.nih.gov/
    9. 17. What is TOXNET? <ul><li>System of databases </li></ul><ul><li>Information about toxicology, environmental health, hazardous chemicals, and toxic releases </li></ul><ul><li>Developed by the Specialized Information Services division (SIS) of the National Library of Medicine (NLM) </li></ul><ul><li>TOXNET is freely available on the web. No subscription, no passwords, no registration, no spam, no pop-up ads. </li></ul>
    10. 18. TOXNET Data Files <ul><li>There are 6 of them </li></ul><ul><li>Click the ? </li></ul><ul><li>for additional information about each database </li></ul>
    11. 19. TOXNET Data Files <ul><li>Content differs from one data file to another </li></ul><ul><li>But format, layout of results, features, and navigation are similar </li></ul><ul><li>Learn the mechanics of one; know the mechanics of all </li></ul>
    12. 20. Data files can be searched individually <ul><li>Select the database to be searched: </li></ul><ul><li>Point the cursor at desired database </li></ul><ul><li>Click </li></ul>
    13. 21. Search will be conducted only in the chosen database
    14. 22. Hazardous Substances Data Bank ( HSDB ) <ul><li>Human and animal toxicity </li></ul><ul><li>Safety and handling </li></ul><ul><li>Human health effects </li></ul><ul><li>Emergency medical treatment </li></ul><ul><li>Antidotes </li></ul><ul><li>Physical & chemical properties </li></ul><ul><li>Interactions </li></ul><ul><li>Environmental fate & exposure </li></ul><ul><li>Manufacturers </li></ul><ul><li>Uses: therapeutic, business, etc. </li></ul>
    15. 24. Integrated Risk Information System ( IRIS ) <ul><ul><li>EPA data </li></ul></ul><ul><ul><li>Risk assessment as a function of toxicity and exposure </li></ul></ul><ul><ul><li>Contains consensus scientific positions and quantitative values on cancer and non-cancer effects that may result from lifetime oral or inhalation exposure to specific chemical substances in the environment </li></ul></ul>
    16. 25. International Toxicity Estimates for Risk Assessment ( ITER ) <ul><ul><li>Contains data in support of human health risk assessment </li></ul></ul><ul><ul><li>Provides comparisons of international risk assessment information in a side-by-side format and explains differences in risk values derived by different organizations. </li></ul></ul>
    17. 26. Genetic Toxicology / Mutagenicity (GENE-TOX) <ul><ul><li>Mutagenicity Studies </li></ul></ul><ul><ul><li>Data structure: assay type, assay code, results, panel report, reference </li></ul></ul><ul><ul><li>Note: Has not been updated since January, 2000. </li></ul></ul>
    18. 27. Chemical Carcinogenesis Research Information System ( CCRIS ) <ul><ul><li>Carcinogenicity studies </li></ul></ul><ul><ul><li>Tumor inhibition studies </li></ul></ul><ul><ul><li>Tumor promotion studies </li></ul></ul><ul><ul><li>Mutagenicity studies </li></ul></ul>
    19. 28. Or, search all TOXNET databases for information:
