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.
Toxic Air Contaminant Special Reports and Emissions Inventories
The table below contains annual toxic air contaminant emission inventories and special reports that summarize and analyze toxic emissions, facility prioritization scores, health risk assessments, TAC air monitoring data and other relevant toxic control program information.
Please note that the TAC Control Program Annual Report for 2025 will be available by July 1.
