Name: Respiratory risk (hazard index) due to cumulative air toxics

Display Field: NAME10

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This map estimates non-cancer respiratory risk (hazard quotient) due to cumulative air toxics from the National Air Toxics Assessment, expressed as a hazard index. A hazard index is defined as, The sum of hazard quotients for toxics that affect the same target organ or organ system. A hazard index (HI) of 1 or lower means air toxics are unlikely to cause adverse noncancer health effects over a lifetime of exposure.
