The Concentration Characteristics of PM₁₀ and PM_2.5 in Eight Cities of China in March, 2013

Abstract:

According to the information of air quality which published by the urban air quality real-time publishing platform, the concentration characteristics of PM₁₀ and PM_2.5 were studied in Kunming (KM), Changsha (CS), Hangzhou (HZ), Shanghai (SH), Harbin (HEB), Beijing (BJ), Wuhan (WH) and Guangzhou (GZ). The results show that the concentrations of PM₁₀ and PM_2.5 exceeded the Ambient Air Quality Standard (GB3095-2012) in varying degrees in March, 2013. The concentrations of PM₁₀in Wuhan is the highest, reached 164μg/m³, exceeded the standard by 9.3%; the concentrations of PM_2.5is much higher in Wuhan, Changsha and Beijing, the average concentrations were 96μg/m³, 103μg/m³ and 110μg/m³, exceeded the standard by 28.0%, 37.3% and 46.7% respectively. The correlation of PM₁₀ with PM_2.5 in most of these cities was good in March. The correlation analysis of pollutant with meteorological factor in Hangzhou, Shanghai, Beijing and Guangzhou was also studied, the results show that the concentrations of PM₁₀and PM_2.5are weakly positive correlation with temperature in the four cities, negative correlation with relative humidity without Beijing, and negative correlation with wind speed.
