TOXMAP Fact Sheet

TOXMAP® is a GIS from the National Library of Medicine (NLM) that uses maps of the United States and Canada to help users visually explore data primarily from the EPA's Toxics Release Inventory (TRI) and Superfund Programs.


Federal law requires facilities in certain industries, which manufacture, process, or use significant amounts of toxic chemicals, to report annually on their releases of these chemicals to the EPA TRI Program. Superfund sites are those throughout the United States and its territories which contain substances that are either designated as hazardous under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), or identified as such under other laws.


TOXMAP helps users create nationwide, regional, or local area maps showing where TRI chemicals are released on-site into the air, water, and ground. It also provides details for releasing facilities and links to authoritative resources for more information. Users can also search locations of Superfund sites on the National Priorities List (NPL) based on the contaminants present at these sites.


The most current version of TOXMAP provides improved usability on mobile devices compared to previous versions. TOXMAP also features Canadian National Pollutant Release Inventory (NPRI) data, U.S. EPA coal plant emissions data, and U.S. commercial nuclear power plants. TOXMAP overlays U.S. Census demographic data, income figures from the Bureau of Economic Analysis, and health data from the National Cancer Institute SEER program, and the National Center for Health Statistics.


NLM has an extensive collection of toxicology and environmental health references (TOXLINE®), as well as a rich resource of data on hazardous chemical substances (HSDB®) in the TOXNET® databases. The data shown in TOXMAP come from:

TOXMAP is a project of the Specialized Information Services Division of the NLM and supports its mission of addressing toxicology and environmental health information needs.
