SDAPCD Toxic Air Contaminants

The California Air Resources Board (CARB) published a mapping tool under its California Air Toxics Assessment (CATA) Program. According to CARB, CATA represents a comprehensive state-of-the-science assessment of toxic air contaminants (TACs) in California. CATA is a unique model-based approach that leverages CARB’s comprehensive TACs emissions inventory and state-of-the-science modeling techniques to estimate ambient concentrations of Diesel Particulate Matter (DPM), heavy metals, and toxic Volatile Organic Compounds (VOCs), which are used to estimate cumulative cancer risk following OEHHA guidelines for inhalation exposure. CATA results are scalable from statewide averages down to the community level (census block/tract averages), which may be different from maximum cumulative risk at a specific location within a census block/tract. CATA is updated on a triennial basis and will incorporate EICG reported data through the Comprehensive California Toxics Inventory (CTI) as it becomes available.

Please visit the CARB CATA webpage or read their Frequently Asked Questions for additional information.
