Air pollution. Conference. Genoa, ITA, 1998/09/28.
The major source of particulate air pollution in Hong Kong is vehicle emission.
The study employed Microenvironment monitoring technique to access the exposure of pedestrians to respirable suspended particulate (RSP) at roadside.
A total of 62 roadside sites in 14 districts representing four different land use categories were selected.
They covered most urbanized and densely populated area.
MINIVol portable samplers were used for RSP sampling.
The range of roadside exposure for 24-hour average RSP was from 46.03 to 337.4 mug/m3 and the average of RSP was 112.95 mug/m3.
Due to the different characteristics of land use, the average concentration and temporal variation were different.
The field data was compared with the data of Environmental Protection Department (EPD) measured at low roof top and at a street level station.
