摘要：

To investigate the pollution characteristics of water soluble ions in PM2.5 and PM10 under severe haze days, both PM2.5 and PM10samples were collected in a city of northeast China under severe haze days during October 20-22, 2013. Nine water-soluble ions in PM2.5 and PM10 including F-, Cl-, NO3-, SO42-, Na+, NH4+, K+, Mg2+ and Ca2+ were analyzed. The results showed that the concentrations of all water-soluble ions mass concentration in night were higher than those in day time, with a ratio of 1.68 for PM2.5 in haze days. The concentrations of SO42-, NO3- and NH4+ were higher and their percentage in PM2.5 were 11.03%, 8.3% and 7.39% in haze days, the same results in PM10 were obtained. The percentages of K+ and Ca2+ in haze and non-haze periods were similar. Based on the ratio of different ions, the pollution from stationary sources were higher than that from mobile sources in haze days, this showed that meteorological factors had greater influences. In comparison with the data of water soluble ions during October and November of 2009, the concentrations from mobile sources were on the rise. ©, 2014, Harbin Gongye Daxue Xuebao/Journal of Harbin Institute of Technology.
