Contribution of Airplane Engine Emissions on the Local Air Quality around Stuttgart Airport during and after COVID-19 Lockdown Measures

Previous airport studies conducted in Los Angeles, Amsterdam and other cities have shown that aircraft can significantly increase air pollutant concentrations around the airport and can be measured even at distances of several kilometers. Since the results cannot be directly transferred from one city to another and no comparable measurements were carried out at Stuttgart airport, the aim of the study was to investigate whether increased air pollution levels can be measured at the airport fence and in the immediate vicinity of the airport in Stuttgart. Since there are busy roads in the immediate vicinity of the airport (e.g. A8, B27), it should also be investigated whether the exhaust gas plumes from road traffic and air traffic can be distinguished.
