Abstract:Objective To understand the concentrations and source of SO42-,NO3-,Cl- and NH4+ in atmospheric PM2.5 in Zhoushan,and to provide reference for controlling PM2.5 and formulating effective environmental protection measures. Methods Monitoring sites in new districts of Zhoushan were set up to continuously collect PM2.5 from 10th to 16th of each month and under the hazy weather during 2015-2016(AQI > 200). The mass concentration of PM2.5 was measured by weighing method,and the concentrations of SO42-,NO3-,Cl- and NH4+ in PM2.5 components was detected by ion chromatography. Results The average daily concentration of PM2.5 in Zhoushan from 2015 to 2016 was(40.91±27.39)μg/m3. The concentration of the four water-soluble non-metal ions in PM2.5 components was 3.56-103.03 μg/m3,with an average of(23.06±20.00)μg/m3,accounting for about 56.64% of PM2.5 contents. The average monthly concentration of SO42- was the highest[(10.35±6.48)μg/m3],while the average monthly concentration of Cl- was the lowest [(0.49±0.73)μg/m3]. The concentration of the four ions was the highest in winter[(37.56±27.74)μg/m3]and the lowest in summer[(12.32±5.88)μg/m3]. The differences between different seasons was statistically significant(P<0.05). The highest concentration of NO3- occurred in winter,which was(14.48±13.28)μg/m3. The concentration ratio of NO3- to SO42- ranged from 0 to 2.58,with an average of 0.55. There were 28 days(14.74%)with the ratio greater than one,22 days of which was in winter. Conclusion The concentration of SO42- was the highest and Cl- was the lowest in atmospheric PM2.5 in Zhoushan. The highest concentration of the four ions occurred in winter. The concentration of NO3- in winter was higher than that of SO42-,suggesting that motor vehicle exhaust might be the main source of PM2.5 in winter.
