US National Library of Medicine NLM TOXMAP

US National Library of Medicine NLM TOXMAP [http://toxmap.nlm.nih.gov/toxmap/main/index.jsp] - TOXMAP (http://toxmap.nlm.nih.gov) is a Geographic Information System (GIS) from the National Library of Medicine (NLM) that uses maps of the United States to help users visually explore data from the EPA's Toxics Release Inventory (TRI) (http://www.epa.gov/tri/) and Superfund Programs (http://www.epa.gov/superfund/index.htm).

TOXMAP helps users create nationwide or local area maps showing where TRI chemicals are released on-site into the air, water, and ground. It also identifies the releasing facilities, color-codes release amounts for a single year, and provides multi-year chemical release trends, starting with 1987. Maps can also show locations of Superfund sites on the National Priority List (NPL) (http://www.epa.gov/superfund/sites/npl), listing all chemical contaminants present at these sites. Users can search the system by chemical name, chemical name fragment, and/or location (such as city, state, or ZIP code). TOXMAP also overlays map data such as US Census population information, income figures from the Bureau of Economic Analysis, and health data from the National Cancer Institute (http://www.cancer.gov/) and the National Center for Health Statistics (http://www.cdc.gov/nchs/).
