California Air Toxics Assessment
The California Air Toxics Assessment (CATA) is an ongoing effort at the California Air Resources Board (CARB) that assesses exposure levels and related health risks from the inhalation of major air toxics in California. CATA identifies areas of high exposure to air toxics, highlights major emission sources in communities, and draws attention to specific air toxic compounds that pose significant health threats.
