    Use the AirToxScreen Mapping Tool to see AirToxScreen's risk results, facilities, and more anywhere in the nation. 

The Air Toxics Screening Assessment (AirToxScreen) is EPA's screening tool that provides communities with information about health risks from air toxics. AirToxScreen is part of EPA's new approach to air toxics that provides updated data and risk analyses on an annual basis, helping state, local and tribal air agencies, EPA, and the public more easily identify existing and emerging air toxics issues.
