Air Pollution at Heathrow Airport, London: April-September, 1970

Calculations have been made of total pollution emissions at Heathrow Airport, London, from aircraft operations, heating installations, and road traffic. Comparisons were made of concentrations of pollution levels from the airport and from nearby residential areas. Measurements of smoke, sulfur dioxide, oxides of nitrogen, carbon monoxide, total hydrocarbons, and deposited matter were also carried out in different parts of the airport.

Results showed that the airport was not contributing unduly to local pollution. At no time did pollution concentrations at the airport even exceed values which have been found in Central London; the highest values obtained came from road traffic in the central area.
