Airport Lead Monitoring in the Pacific Southwest

National Resources

To learn more about air pollutant emissions from aviation, lead emissions from piston-engine aircraft, visit EPA’s page on emissions from aircraft.

The EPA has recently summarized the complete set of ambient air lead concentrations from monitoring conducted at airports as part of the National Ambient Air Quality Standards (NAAQS) monitoring requirements. The summary of these data is available at Airport Lead Monitoring Program Overview (PDF) (4 pp, 214K).

Monitors at two airports, the San Carlos Airport in the Bay Area of California and the McClellan-Palomar Airport in San Diego, California, recorded average 3-month lead concentrations that exceed the lead NAAQS level of 0.15 ug/m3.
