In a July 2022 congressional hearing, Chairman Ro Khanna highlighted the health dangers of leaded aviation fuel (Avgas) still used in small general aviation aircraft, noting that children near airports in communities of color face blood lead levels exceeding those seen during the Flint water crisis. The statement criticizes the FAA and EPA for failing to act urgently on phasing out leaded fuel, despite the existence of viable unleaded alternatives, and accuses oil companies and aviation industry groups of deliberately delaying the transition. Khanna calls on federal agencies to accelerate approval of lead-free fuel options, involve affected communities in decision-making, and use infrastructure funding to support the switch to unleaded aviation fuel.

This 2021 report by Mountain Data Group, commissioned by Santa Clara County, examines the health risks posed to children living near Reid-Hillview Airport in California due to lead emissions from leaded aviation gasoline. It analyzes statistical associations between children's blood lead levels and factors such as residential distance from the airport, aircraft traffic, and fuel sales. Note that while this report focuses on lead exposure from aviation fuel at a California airport, it does not address noise policy or Sea-Tac Airport operations.

This EPA technical report estimates airborne lead concentrations near U.S. airports caused by piston-engine aircraft burning leaded aviation gasoline (avgas). Using air quality modeling and extrapolation methods, the study identifies airports where lead levels may exceed national air quality standards, particularly in areas close to aircraft run-up zones. While not specific to Sea-Tac Airport, the findings are relevant to understanding aviation-related air quality impacts at airports nationwide.
