Selected Environmental Justice Screening and Mapping Tools (EJSCREEN) Measures

Three measures from the EJSCREEN and National Air Toxics Assessment (NATA) are available. These data were released in 2018, based on 2014 emissions data. Three measures include: 1) Diesel particulate matter level in the air, in g/m3; 2) lifetime cancer risk from inhalation of air toxics; and 3) ratio of exposure concentration to health-based reference concentration.
