典型城市环境空气中总悬浮颗粒物源项分析实例研究

In this paper, the relationship between the inorganic components in TSP and their pollution sources in four typical cities in Jilin Province during heating and non-heating seasons are further studied by statistical analysis. The results are as follows: During heating season, the main sources of air pollution in City A, City B, City C and City D are road dust and soil and sand blown by wind, while coal-fired dust and construction dust take a minor effect on the air pollution. During non-heating season, the main sources of air pollution in the four cities are road dust, soil and sand blown by wind, soil and sand blown by wind and particle mass, yet coal-fired dust and construction dust still have inconspicuous impact on the quality of the air in these cities. The improvement measures of treating TSP can be put forward by analyzing and comparing the current situation of pollution in these four cities statistically. The results of analysis provide us the treatment of pollution validly and scientifically.
