Abstract

To get the whole picture of the air quality change of Shanxi Province, the data of six pollutants collected from 58 state controlling air sampling sites including SO2, NO2, PM10, CO, O3 and PM2.5 during November 2016 to July 2017 were analyzed. The results showed that the air quality of Shanxi Province since November 2016 was worse than that of Beijing, Tianjin and adjacent provinces. The most contaminated air in Shanxi occurred at Taiyuan basin (Taiyuan, Jinzhong), Linfen, Yuncheng and Jincheng. The six pollutants showed evident spatial distribution features. In terms of time series change, air quality during heating period was worst, and contaminants during that time contributed to the majority of pollutants in the whole year. The six contaminants also showed obvious daily and monthly change patterns. This paper examined impacts of heavily contaminated weather and dust storm on air quality. Calculation revealed that every heavily contaminated day would result in increase of PM2.5 by 0.38µg/m3, and a dust storm could lead to an increases of PM10 and PM2.5 by 0.71µg/m3 and 0.20µg/m3 respectively. Based on the analysis of air pollution status in Shanxi, some suggestions and possible solutions to pollution problems were also given in this paper.
