What AQHI should I refer to?

The health effects of air pollution depend on the concentrations of the air pollutants and the duration of exposure. Exposure to moderately high pollution levels for a short period of time normally will not lead to significant health problem.

The general AQHI is more relevant to most of us as it represents the air pollution that we are exposed to for most of the time. The roadside AQHI is relevant to those who spend several hours continuously in a day in busy streets.

At present, EPD operates 15 general air quality monitoring stations and 3 roadside air quality monitoring stations respectively. Data from these stations will be used for reporting general AQHI and roadside AQHI respectively.

Areas of similar land uses will have similar air pollution levels. If you live in a district that does not have an air quality monitoring station, you may refer to the AQHI measured by the corresponding station as shown in the table below:
