This database contains toxic Volatile Organic Compounds (VOC) readings recorded at nearly 40 air quality sampling stations throughout California.  Data are reported on specific days of each month and year as indicated and are not available for all possible combinations of categories and areas.


According to the California Air Resources Board, VOCs are organic compounds that can vaporize easily at ambient temperatures.  Some VOCs are highly reactive and play a critical role in the formation of ozone.  Other VOCs have adverse, chronic, and acute health effects.  In some cases, VOCs can be both highly reactive and potentially toxic.  Sources of VOCs include motor vehicle exhaust, waste burning, gasoline marketing, industrial and consumer products, pesticides, industrial processes, degreasing operations, pharmaceutical manufacturing, and dry cleaning operations.  See Toxic Air Contaminants Monitoring for additional information.
