In order to understand air pollution problems, develop cost-effective policies and solutions and assess the extent to which standards and targets are being achieved or violated, the Environmental Protection Department of the Hong Kong Government measures air pollution in Hong Kong through 14 monitoring stations located around Hong Kong. [1] The monitoring network allows for the assessment of the public’s exposure to air pollution and to provide public information on current and forecast air quality. [2]


There are 11 general monitoring stations and 3 roadside monitoring stations. These fixed stations measure the air for gaseous and particulate pollutants. Data is available on the EPD website about the comparison of maximum hourly, daily and annual pollutant concentrations with the relevant Air Quality Objectives. [3]


A recent study has shown that actual personal exposure levels at roadside could be 2 – 3 times higher than what is measured by the EPD.[4]
