| Abstract: | In line with the ever increasing living standards in Hong Kong, the demand of energy has also been growing. The process of extracting energy from fossil fuels would unavoidably contribute air pollution problems to a certain extent even if advanced air pollution control equipments are being used. For the pollutants emitted to atmosphere, there are altogether nearly twenty environmental air quality monitoring stations with respective monitoring objectives. It is understood that apart from the influence of emission close to source, urban and rural air pollution levels also depend on the dispersion and transport of air pollution which in turn is closely related to the meteorological, topography and land use of the region. Hence, introduction of pollution index related to the meteorological parameters will be useful in the indication of air pollution level in Hong Kong. In this study, attention is drawn to the identification of pollution sources with the analysis of meteorological data. Our study reveals the following: Firstly, for effective monitoring of the air pollutants in each district of Hong Kong, installation of an Opsis system is an appropriate option. Secondly, some important meteorological parameters such as relative humidity should be considered in the future dust emission regulation. Thirdly, buffer zones should be provided for residential buildings located in polluted urban areas. Fourthly, the solar radiation and wind speed obtained from the Royal Observatory are closely related to photochemical reaction and the pollution transport respectively. Finally, it is possible to use a simple methodology for finding the causes leading to the pollution episode. It is recommended to perform a further examination of the pollution index if it is intended for public use. This involves the further analysis of the close relationship of the concentration of pollutants with meteorological data. Similarly, the relationship between the RSP/TSP ratio and the relative humidity should be further examined after the chemical analysis of TSP and RSP samples have been completed. |
