Sources of sulfur dioxide pollution in Hong Kong
- Environmental Protection Dept. Wan Chai (Hong Kong)
Sulfur dioxide pollution problem was serious in Hong Kong before the implementation of the fuel restriction regulations in July 1990, which restricted the use of low sulfur content fossil fuels. Since then SO{sub 2} concentrations dropped drastically. There was no exceedance of the Hong Kong Air Quality Objectives (AQO) in 1991, comparing to 13 exceedance in 1989, and the Hong Kong annual average reduced from 34 {mu}g/m{sup 3} in 1989 to 21 {mu}g/m{sup 3} in 1991. However, it doesn`t mean that SO{sub 2} can be neglected. In 1993, there were two exceedances of the 1-hour AQO of 800 {mu}g/m{sup 3}, and the Hong Kong annual average increased again to 26 {mu}g/m{sup 3}. The major emission sources of SO{sub 2} in Hong Kong are the power stations, which accounted for 84% of the total 185 K tonnes of SO{sub 2} emissions in 1993. Though these stations are at the down-wind side of the territory, the potential impact should not be over looked. Results are given.
