| 摘 要： | 为了研究郑州市PM_(2.5)中部分金属元素在采暖期与非采暖期的来源、污染特征并进行相应的生态风险及健康风险评价,于2016年春季非采暖期和冬季采暖期在河南郑州设置采样点,采集有效膜样本105个.测定PM_(2.5)质量浓度及其中Zn、Pb、Cu、As、Cd、Co、Mn、Fe共8种金属元素含量,郑州2016年非采暖期PM_(2.5)质量浓度日均值为113.41μg·m~(-3)、采暖期为216.99μg·m~(-3),采暖期中Cu、Zn、As、Cd这4种元素的浓度分别是非采暖期的2.3、2.0、1.9、1.5倍,季节性差异明显.富集因子分析显示郑州地区Cd元素富集程度最高已超过1000,受人为影响严重.PMF源解析表明燃煤源及机动车源是郑州采暖期重金属主要来源,贡献率为48.00%和34.95%;扬尘源及交通污染源在非采暖期的贡献率为55.92%和31.08%.健康风险评价显示3种致癌元素As、Cd、Co的致癌风险值均小于10~(-4),Mn的非致癌风险值最高为0.9,可能存在一定的非致癌风险.
