摘要：	为了探究新乡地区年际间冬季PM_(2.5)组分的变化特征和污染来源,于2015年冬季和2016年冬季分别在新乡市区进行连续1个月的膜采样,测定PM_(2.5)质量浓度、金属元素含量及其水溶性离子成分含量,并结合气象因素进行分析.结果表明,新乡地区2015年和2016年冬季采样期间PM_(2.5)的质量浓度日均值分别为226μg·m~(-3)和224μg·m~(-3),污染水平较高.观测期间,新乡冬季PM_(2.5)中Cd和Pb金属元素富集明显,富集因子超过1000.且与2015年相比,2016年金属元素(除Ag和Ni)浓度下降约7. 83%～73. 33%,富集程度均趋于降低.水溶性离子以SO_4~(2-)、NO_3~-和NH_4~+这3种为主,2016年在PM_(2.5)中占比上升25. 1%.综合两种成分分析,新乡地区的PM_(2.5)污染呈现出金属污染向二次水溶性离子污染转移的趋势.综合PCA和PMF源解析结果显示,新乡市冬季有4种主要排放源,即尘土、二次源、工业源和化石燃料燃烧源,2015年冬季主要来源是土壤和建筑扬尘混合源,贡献率37. 46%,2016年主要来源是交通及工业生产中的二次气溶胶污染源,贡献率为34. 94%.
