2002 National-Scale Air Toxics Assessment

The EPA has just released the results of its 2002 national-scale assessment of air toxics emissions (NATA). The purpose of the national-scale assessment is to identify and prioritize air toxics, emission source types and locations which are of greatest potential concern in terms of contributing to population risk. EPA uses the results of these assessments in many ways, including: working with communities in designing their own local-scale assessments, setting priorities for improving data in emissions inventories, and helping direct priorities for expanding and improving the network of air toxics monitoring.
