| 摘 要： | 为了探究郑州-新乡地区PM_(2. 5)中各化学组成的污染特征和可能来源,用中流量大气采样器于2016年冬季分别在郑州、新乡市区进行连续1个月大气PM_(2. 5)膜采集,利用重量法、电感耦合等离子体质谱法(ICP-MS)和离子色谱法分别进行了PM_(2. 5)浓度、17种金属元素的含量和7种水溶性离子含量的测定,并采用富集因子法和主成分分析法分析元素污染特征及其来源.结果表明,新乡地区2016年冬季PM_(2. 5)的质量浓度日均值为223. 87μg·m~(-3),郑州2016年冬季PM_(2. 5)质量浓度日均值为226. 67μg·m~(-3),两地污染水平相对较高.两地PM_(2. 5)中主要常量元素均为Al、Ca和Fe,约占17种元素总量的50%,而主要重金属含量差异明显,新乡PM_(2. 5)中重金属的含量均高于郑州地区,其中Cd、Ag和Pb富集因子超过1 000,新乡Cd元素富集突出.两地水溶性盐离子均以SO_4~(2-)、NO_3~-和NH_4~+这3种离子为主,占水溶性离子总量超过94%,(NH_4)_2SO_4和NH_4NO_3是两地PM_(2. 5)中主要存在形式.源解析结果显示,新乡2016年冬季的主要来源是生物质燃烧及二次气溶胶混合源,贡献率为34. 94%.郑州2016年冬季PM_(2. 5)的主要来源是燃煤及交通混合源,贡献率为33. 99%.
