Air Monitoring Reports

Back to Toxic Air Contaminant Program

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. In general, two types of monitoring are conducted: ambient monitoring in selected communities (to measure concentrations over several weeks or months) and application-site monitoring in the immediate vicinity of specific pesticide applications (to measure concentrations over several hours or days). Monitoring studies h2017ave been conducted for the following pesticides:

Electronic versions of the following reports are available to the public upon request. If you would like to request any of the listed reports, please send an email to Air.Monitoring@cdpr.ca.gov with your request. Be sure to include a valid email address where the requested reports are to be sent to.
