Welcome to the Department of Pesticide Regulation

Air Program

Back to Home Page

Protecting the air we breathe is one of the highest priorities of the Department of Pesticide Regulation (DPR). We focus not only on preventing health problems that can be caused by pesticide air toxins, but also on reducing pesticide emissions that contribute to air pollution.

  • Air Quality Initiative - Moving to set a national benchmark for controlling pesticides in air, DPR in 2006 launched a major initiative to improve California’s air quality.
  • Fumigant Resource Center - Fumigants are gaseous pesticides widely used in agriculture. These air toxins are also a major source of smog-producing volatile organic compounds (VOCs). DPR has launched initiatives to assess fumigant hazards, reduce environmental impacts, and support research to find less risky alternatives.
  • Toxic Air Contaminant (TAC) Program - Under this program, DPR evaluates pesticides in air and, in cooperation with scientific reviewers, determines potential risks. If we identify a pesticide as a TAC, we work with air districts and others if stricter controls are needed.
  • Volatile Organic Compound (VOC) Emissions - DPR tracks emissions from agricultural and structural pesticide products of these smog-producing compounds, and implements measures to reduce them.
