Change of ambient air quality in Shanghai area
摘要
Abstract
According to Shanghai’s ambient air quality monitoring data between 2000—2013,the air quali-ty was statistically analyzed in terms of SO2 ,NO2 and PM10 concentrations and pH.The results showed that the SO2 concentration dropped from 0.061 mg/m3 to 0.024 mg/m3 ,the NO2 concentration dropped from 0.090 mg/m3 to 0.048 mg/m3 and the PM10 concentration dropped from 0.099 mg/m3 to 0.071 mg/m3;but the pH of rainfall was 4.39—5.19,and the frequency of acid rains presented an ascending trend.In the past 14 years the good-grade rate of ambient air quality was 89.7%,being better in summer than in winter.In terms of PM10 ,the central met-ropolitan districts such as Yangpu District,Putuo District,Xuhui District and Huangpu District were much worse than the non-central metropolitan districts such as Jinshan District and Chongming County that were the best in air quality.The related data analysis indicated that the coal-burning industry,dust-producing construction sites and automotive vehicles’exhaust gas were major air pollution sources in Shanghai.关键词
