Service Description: This service contains cancer risk, respiratory hazard index (HI), and ambient concentration estimates at census tract resolution for the continental US, Alaska, Hawaii, Puerto Rico, and the US Virgin Islands. The estimates are based on a modeling analysis using EPA's 2011 National Emissions Inventory (NEI), version 2. The cancer risk and respiratory HI layers include source group and pollutant contribution information. The cancer risks are presented on a per million basis (e.g., a value of 10 means 10 in a million risk). The ambient concentration data are in units of µg/m3.
