Then the distribution model of elevated road pollutant concentration was established, taking vehical density as the main variable.
This chapter describes methods of estimating airborne pollutant concentration distrubutions associated with various emission sources.
The methods described in this chapter and utilized in the sample problem calculation can't be expected to yield perfect predictions of groundlevel pollutant concentrations.
By arranging the position of buildings, the area of high pollutant concentration can be reduced efficiently.
At the same time, the correlation coefficient between temperature vertical decrease rate of low layer atmosphere and air pollutant concentration is negative.
