| 摘 要： | 为探究郑州市PM2.5的污染水平，水溶性离子组成特征并进行来源分析，于2016年四季进行PM2.5周年膜采样，每个季节连续采集30 d共采集有效样品170个.分别采用重量法测定PM2.5的质量浓度，离子色谱法测定水溶性离子浓度，并使用主成分分析法对其进行来源解析.结果表明，在采样期间郑州市PM2.5年均质量浓度为150.72μg·m-3，季节性特征明显，冬季最高，夏季最低，秋季略高于春季.NH4+、NO3-、SO42-是郑州PM2.5中最主要的无机水溶性离子，三离子之和占所测7种水溶性离子总含量的比例分别为92.55%（春）、92.94%（夏）、93.06%（秋）和93.15%（冬）.阴阳离子电荷当量年均值为0.886，PM2.5呈弱碱性.春、夏季节铵盐的存在形态为NH4NO3和（NH4）2SO4，秋季铵盐的存在形式可能为NH4NO3、（NH4）2SO4和NH4HSO4，冬季NH4+除上述3种存在形式外，可能还以NH4Cl或其他形式存在.郑州市大气中存在较强的SO2、NO2二次转化过程，水溶性离子的主要来源是二次转化过程，化石燃料和生物质燃烧、矿尘、农业活动以及土壤和建筑尘等.
