| 摘 要： | 为了全面了解当前青岛地区大气气溶胶中水溶性组分的特征及来源,于2008年1～12月在青岛市区连续采集了总悬浮颗粒物(TSP)样品,运用离子色谱法对其主要的水溶性阴阳离子进行了分析.结果表明,SO24-、NO3-、NH4+和Cl-是TSP中水溶性离子的主要成分,四者质量浓度之和占总水溶性离子质量浓度的86.9%.TSP及其水溶性组分存在明显的季节变化,其来源也存在多源性.Na+、NH4+、Ca2+、F-、Mg2+均为冬季最高,夏季最低,K+、PO34-为秋季最高,夏季最低,Cl-为冬季最高,秋季最低,NO3-则为春季最高,夏季最低,而SO24-为春季最高,秋季最低.不同天气对颗粒物和气溶胶中水溶性离子影响很大.颗粒物浓度在晴天时最低,其次是雾天,再次是烟雾和霾,沙尘天气下质量浓度最高.Na+、Mg2+、Ca2+、F-、Cl-和PO34-在烟雾天气下的平均浓度最高,而NH4+、K+、NO3-和SO24-则是在霾天气下质量浓度最高.

| Abstract: | To collect comprehensive information on the characteristics and sources of water-soluble ions in the atmospheric aerosol in Qingdao, samples of total suspended particles (TSP) were collected from January to December 2008, and the concentrations of the major water-soluble inorganic ions were analyzed using ion chromatography. The results showed that SO42-, NO3-, NH4+ and Cl- were the dominant water-soluble ions in TSP, the sum of the four accounting for 86.9% of water-soluble ions in mass concentration. TSP and water-soluble inorganic ions showed obvious seasonal variations and there were a variety of sources. The mass concentrations of Na+, NH4+, Ca2+, F- and Mg2+ were highest in winter and lowest in summer. The concentrations of K+and PO4+ were highest in autumn and lowest in summer. NO3-, Cl- and SO42-concentrations had the highest values in spring, winter, and spring, respectively. Different weather conditions had great influence on the concentrations of TSP and water-soluble ions. The mass concentrations of TSP were highest in dust weather followed by haze, smog, fog and sunny days. The average mass concentrations of Na+, Mg2+, Ca2+, F-, Cl- and PO4+ were highest in smog days while the other ions in haze days. |
