Back to Toxic Air Contaminant Monitoring

California’s Department of Pesticide Regulation (DPR) and Air Resources Board (ARB) conduct air monitoring studies for pesticides that are candidate toxic air contaminants, as well as for pesticides that are designated as toxic air contaminants.

Monitoring studies have been conducted for the following pesticides:
