Toxic Air Contaminants

Get the latest information and findings from the Air District's emissions inventory of toxic air contaminants.

Toxic Air Contaminants

Certain air pollutants are classified as toxic air contaminants, or TACs, because they are known to cause or contribute to adverse health impacts. Adverse health impacts from exposure to toxic air contaminants may include temporary minor conditions, such as eye or skin irritation, permanent injury, or serious diseases including cancer. California’s Office of Environmental Health Hazard Assessment identifies potential health impacts and develops toxicity information for toxic air contaminants.

Facility Toxic Emissions and Prioritization Tool

Each year, the Air District collects toxic air contaminant emissions data, or sufficient data to estimate TAC emissions, from permitted facilities. The Air District uses this information to ensure facilities comply with Air District rules and regulations and to determine whether further evaluation is warranted. The Facility Toxic Emissions and Prioritization Tool provides a way to easily view the latest year toxic air contaminant emissions and prioritization scores for all permitted facilities within the Bay Area.
