-- = Pollutant not monitored.
* Less than 12 full months of data. May not be representative.
1) Mojave Desert Air Basin.
2) Salton Sea Air Basin.
f) Total suspended particulates, lead, and sulfate were determined from samples collected every 6 days by the high volume sampler method, on glass fiber filter media.
h) Special monitoring immediately downwind of stationary sources of lead was carried out at several locations in 1995. The maximum monthly average concentrationage was 0.62 µg/m3, and the maximum quarterly average concentration was 0.60 µg/m3, both recorded in Area 5, Southeast Los Angeles County.
