TOXMAP: A GIS Information Portal to Environmental Health Databases
Track: Health and Human Services
Author(s): Marti Szczur, Chris Krahe, Colette Hochstein

The National Library of Medicine (NLM) has an extensive collection of environmental health information, including bibliographic and factual data on hazardous chemical substances in its TOXNET databases. TOXNET also provides access to the EPA Toxic Release Inventory data, which covers air, water, and land releases, as reported by industrial facilities around the United States. Built using ArcIMS, NLM has developed a web-based system, TOXMAP. Users can dynamically create maps that show where chemicals are released and directly link to the appropriate chemical data records in TOXNET. By extracting the associated regional geographic terms from the displayed map (e.g., rivers, towns, county, state), TOXMAP (http://toxmap.nlm.nih.gov/) also provides customized chemical and/or region-specific searches to NLM's bibliographic bio-medical databases resources. This paper will focus on the design concepts, implementation strategy, challenges, and feedback from users. It will also address issues associated with data accuracy, the risk of data misinterpretation, and future directions.
