| Abstract | Acidic air pollution and deposition have brought damage t o forests, materials,
soil and human health causing great economic losses in China especially in t h e
south-west ern a rea. This research study deals with t h e problem by simulating
yearly average concentration and deposition around Chongqing with an advanced
box model developed by B.E.A. Fisher and successfully used in Europe .
Th e simulation reveals that in Chongqing city, high sulfur dioxide emission
and the low wind velocity cause the high concentration a nd deposition around
t h e city. The sulfate concentration is relatively high due to the humid weather.
The simulation also detects that the southern city suffers more pollution than
other areas.
The sensitivity analysis shows that such parameters as wind velocity, wind
direction, transformation and deposition velocity are relatively important. Others
such as the eddy diffusivity, mean wet and dry periods, etc., are less important
to the accuracy of the model. It also shows that increasing the height of emission
sources can still a bat e t h e pollution near the city . |
