Hong Kong airport’s proposed HK$136 billion ($17 billion) third runway may cause the level of pollutant nitrogen dioxide in the facility’s vicinity to exceed the limit set by the city’s government, according to a study.
Annual cumulative concentrations of the gas in the airport and nearby areas may range between 16.5 micrograms and 81.1 micrograms per cubic meter, Ove Arup & Partners Hong Kong Ltd., appointed by the Airport Authority Hong Kong to assess the effect on air quality, said in its report. The government has proposed halving the legal limit for nitrogen dioxide, found in vehicle exhaust, in Hong Kong to 40 micrograms per cubic meter.
