Emissions of Oxides of Nitrogen from Aircraft

Local and regional air quality impacts of airport operations

“…Such studies indicate that airports are important emission sources and, therefore, contributors to air quality degradation in their own immediate vicinity but their importance at the regional scale is relatively small and smaller still at the national level (Yamartino et al, 1980;Naugle and Fox, 1981). In terms of concentrations early studies suggest airports and aircraft are relatively small regional polluters although hot spots of NOx and CO concentrations have been identified around terminal areas (Jordan and Broderick, 1979). Pollutant concentrations at airports were observed to be similar to or less than those found in urban areas.…”
