TOXMAP® ( is a Geographic Information System (GIS) from the Division of Specialized Information Services of the US National Library of Medicine® (NLM) that uses maps of the United States to help users visually explore data from the US Environmental Protection Agency (EPA)'s Toxics Release Inventory (TRI) and Superfund Program, as well as some non-EPA datasets.

TOXMAP requires the Adobe® Flash® Player, a free plug-in for all major web browsers. Your computer might already have the Flash Player installed; if not, you can download it from Adobe.

At present, the Flash-based TOXMAP is in a "beta" or pre-release state. We are actively soliciting feedback, fixing problems, and adding datasets and functionality. As a pre-release, TOXMAP has incomplete areas and is still undergoing testing. We appreciate your understanding and patience during the beta phase of development.

TOXMAP classic ( is an alternative to the Flash-based TOXMAP. However, although TOXMAP classic will receive data updates, it will receive no further enhancements.
