Assessing the impact of air pollution sources in Hong Kong, a densely populated city

Journal of Environmental Sciences 1993年第1期5卷 1-15页

作者： Feng Yingsheng (Y. S. Fung) Department of Chemistry, Hong Kong University, Hong Kong Dept. of Chemistry Hong Kong Univ. Hong Kong.

As the simple dispersion model tested is not sufficiently accurate to predict the SO2 concentration in complex terrain commonly encountered amongst high rise buildings in Hong Kong, and the lack of comprehensive local wind data at most sites prevents the use of more advanced dispersion model to assess the impact of major air pollutant sources, a receptor model approach is adopted for the apportionment of air pollution sources in Hong Kong. The preliminary results obtained are presented and discussed.

This paper deals with de the fiasco created by the Tehri Uttarakhand, India, particularly resettlement and rehabilitation tailed analysis of High Dam in in terms of of the local inhabitants. Aspects pertaining to the environmental issues are also discussed. Currently, the river valleys in Uttarakhand state of India are the targets of increasing hydroelectric projects. Virtually all rivers are being exploited for generating environmental friendly power. Having being learned the hard lesson from Tehri Dam, it has been decided to opt for such schemes in which comparatively little submergence hnd tempering with the fragile eco-systems is involved However, our observations suggest that even in such schemes if due care is not taken they may turn out to be a failure.
