EPA’s Data and Analysis of Piston-engine Aircraft Emissions of Lead at U.S. Airports
The EPA is evaluating the air quality impact of lead emissions from aircraft using leaded aviation gasoline as described in the Federal Lead Action Plan to Reduce Childhood Lead Exposures and Associated Health Impacts and in response to petitioner’s requests.
The materials provided below describe methods to calculate airport lead inventories, fact sheets on air quality monitoring at airports, a report and fact sheet on model-extrapolated estimates of lead concentrations at airports and estimates of the number of people who live near or attend school near airports.
Following is a list of additional documents related to the ongoing study of airborne lead at airports and the development of unleaded aviation fuel.
