Air pollution in Guangzhou - Alex Hofford (www.alexhofford.com)

The Hong Kong Government blames cross-border pollution for many of the city’s air pollution problems.[1]


Local emissions of SO2, NOx, PM10, non-methane VOCs and CO have fallen significantly by 55% - 83% from their peaks in the 1990s, measured by tonnage. Air quality improvement in Hong Kong, however, is not commensurate with emission reductions, underlining the impact of other pollution sources outside Hong Kong. [2]

Monitoring stations in Yuen Long and Tung Chung have recorded some of the highest hourly and daily readings for pollutant concentrations in recent years. These locations serve as the first screening stations for regional pollutants coming from the mainland. [1]
