摘　　要：根据2005～2006年江苏田湾核电站大气吸收液（AAS）和总悬浮颗粒物（TSP）中氯离子的一年数据,分析了室内外大气各种形态氯离子的分布特点及变化规律,并对过滤器性能进行了初步评价.结果表明：该站大气氯离子浓度大小依次为：室外吸收液〉室内吸收液〉室外TSP〉室内TSP,年均值分别为28.12,19.20,4.22,0.11μg/m^3.现有过滤器可以有效过滤室外总悬浮颗粒物,但对室外气体中氯离子的过滤效率仅为32%.相关性分析表明,室内外吸收液中氯离子浓度显著相关,相关性系数为0.859.因此,室内大气氯离子主要来源室外气态或微小气溶胶.Concentration of chloride ions in the atmospheric absorbed solution （AAS） and total suspended particles （TSP） samples collected in Tian Bay nuclear power plant between 2005 and 2006 was determined by the way of ion chromatography. The distributions and variations of chloride ions in the indoor and outdoor air and the performance of air filter were also investigated. The results showed that the annual average concentrations of chloride ions were 28.12, 19.20, 4.22 and 0.11μg/m^3 in the outdoor AAS, indoor AAS, outdoor TSP and indoor TSP, respectively. The outdoor TSP could be effectively filtered by the existing air filter, but the filter efficiency of chloride ions in the outdoor air was only 32%. Besides, there was a significant positive correlation between the outdoor AAS and indoor AAS, and the correlation coefficien was 0.859. Therefore, it could be inferred that the chloride ions in the indoor air mainly came from outdoor sources.
