  • 摘要: 为研究盘锦市冬季大气PM2.5中元素污染特征及其来源，于2017年1月采集盘锦市3个点位PM2.5样品，通过富集因子以及因子分析法对盘锦市PM2.5中载带的元素进行污染特征分析及来源解析.结果表明，盘锦市冬季大气PM2.5日均浓度顺序为开发区>第二中学>文化公园，日均浓度值超过环境空气质量标准（GB3095-2012）二级标准限值（75 μg·m-3）的天数分别为9、4、7 d；各元素浓度平均值由高到低依次为Al > Ca > Fe > Na > Mg > Zn > Pb > Mn > V > As > Cu > Ni > Cr > Cd，其中Al、Ca、Fe、Na、Mg、Zn和Pb元素质量浓度之和占所有检测元素浓度的96.85%.富集因子分析表明，Cd、Zn、Pb、As、Cu属于极强富集，Ni、V属于强烈富集，Cr、Ca和Mg属于显著富集，Mn、Na属于中度富集，Fe属于轻微富集.因子分析结果表明，盘锦市冬季大气PM2.5污染元素主要来源为煤烟尘、道路交通尘、燃油尘和土壤扬尘.
    Abstract: In order to explore the sources and characteristics of elements in PM2.5 during winter of Panjin City, PM2.5 samples were collected at three monitoring sites in January 2017. Pollution characteristics and source of elements component in PM2.5 were analyzed by enrichment factor (EF) and factor analysis (FA). The results showed that the order of PM2.5 concentration was Development Area > Secondary Middle School > Cultural Park. There were 9, 4 and 7 days at the three sites respectively in which the 24-hour average mass concentration exceeded the secondary standard limit of the ambient air quality standard (GB3095-2012) (75 μg·m-3) during the sampling period. The mass concentrations of elements in PM2.5 were, in descending order, Al, Ca, Fe, Na, Mg, Zn, Pb, Mn, V, As, Cu, Ni, Cr, Cd. The proportion of mass concentrations of Al, Ca, Fe, Na, Mg, Zn, Pb accounted for 96.85% of the total determined elements mass concentration. The enrichment factors of Cd, Zn, Pb, As, Cu were extremely high, and Ni and V were very high. The enrichment factors of Cr, Ca, Mg were significant, and Mn, Na were moderate, Fe was slightly. The results of FA showed that the main sources of the pollution elements in PM2.5 during winter in Panjin were coal combustion, vehicle exhaust, fuel oil and soil dust.
