于2014年春季在长春采集大气PM2.5样品,对PM2.5及其水溶性离子特征进行了分析.结果表明,2014年长春春季PM2.5质量浓度为34.9～237.5 μg/m3,平均质量浓度为125.6 μg/m3.9种水溶性离子的总质量浓度为24.3～71.2 μg/m3,平均质量浓度为39.8 μg/m3,平均浓度大小表现为SOi＞Ca2+＞Cl-＞ NH4+＞ NO3-＞ Na+＞K+＞ Mg2+＞ F-.后向轨迹表明,长春春季PM2.5污染主要来源于内蒙古西北方向和长春东南部渤海、黄海地区.
Characteristics of PM2.5 and its water-soluble ions in spring in Changchun, China
PM2.5 samples were collected during spring of 2014 in Changchun.The characteristics of PM2.5 and its water-soluble ions were analyzed.Results showed that PM2.5 mass concentrations were 34.9-237.5μg/m3 with average of 125.6 μg/m3.The mass concentrations of 9 water-soluble ions were 24.3-71.2 μg/m3 with average of 39.8 μg/m3.The average concentrations of 9 water-soluble ions showed SO42-＞Ca2+ ＞C1-＞NH4+＞NO3-＞Na+ ＞K+ ＞Mg2+ ＞F-.The backward trajectory showed that the PM2.5 mainly came from northwest of Inner Mongolia and southeast of Changchun.
