| Abstract: | Based on the Shenyang meteorological data and the air pollutant concentration data in winter from 2016 to 2017,the characteristics of air pollution in winter were comprehensively analyzed,and the particle transport path and the contribution of the potential source areas were also analyzed.The results showed that PM2.5 was the main pollutant during the winter in Shenyang.The average concentration of PM2.5 reached 149μg/m^3,and the maximum value was 273μg/m^3.Beside the local emissions,the environmental air particles in Shenyang area were mainly affected by the transmission in the northeast of Inner Mongolia and the north of Beijing-Tianjin-Hebei.The transmission in the northeast of Inner Mongolia accounted for about 70% of the total gas volume.The analysis of potential source areas showed that the central and western of Liaoning,the Northeast of Inner Mongolia and the north of Beijing-Tianjin-Hebei were the potential source areas.The weight analysis of the concentration trace showed that the majority of Liaoning,the northeast of Inner Mongolia,the north of Beijing-Tianjin-Hebei and the part of Shandong contributed most particle concentration in Shenyang.The WCWT value of PM2.5 was greater than 50μg/m3 after its modification,and the WCWT value of PM10 was greater than 100μg/m^3. |
