| 摘 要： | 于2015年12月—2016年1月(冬季,采暖季)和2016年3—4月(春季,非采暖季)在河南新乡采集了125个膜样本,用重量法分析了PM_(2.5)的质量浓度,电感耦合等离子体-质谱分析仪(ICP-MS)分析了20种常见的金属元素,离子色谱(IC)分析了颗粒物中NH_4~+、K~+、Mg~(2+)、Ca~(2+)、Cl~-、NO_3~-、SO_4~(2-)7种水溶性离子,同时结合气象因子与主因子分析法(PCA)对PM_(2.5)进行追因溯源.结果表明:新乡市采暖季和非采暖季PM_(2.5)浓度均值分别为250.17和148.67μg·m~(-3),污染严重;主要金属元素均为Al、Ca、Zn、Fe、Pb,5种元素总共分别占20种金属元素总量的68%和51%;NH_4~+、SO_4~(2-)和NO_3~-占比均超过水溶性盐离子总量的90%.气象条件与地形条件分别对采暖季和非采暖季的PM_(2.5)局地污染有重要影响;PCA结果发现,新乡市采暖季的PM_(2.5)有3个主要来源,分别为燃煤源(31.86%)、农业源/机动车尾气源(19.34%)和土壤/地面扬尘(22.69%);而非采暖季的3个主要来源分别为机动车尾气源/地壳源(41.67%)、煤炭燃烧源/工业排放源(32.20%)及地面扬尘(12.18%).可见煤炭燃烧、机动车尾气排放对新乡市冬、春季大气污染的贡献较大.
