Abstract

Spatial variations and sources of atmospheric pollution by measuring of 48 major and trace elements were determined in Iskenderun industrial region using tree components samples (pine needle, bark, branch, stem and litter) and soil samples taken from 21 industrial sites and 6 background sites. The highest elemental concentrations were found at industrial sites and generally a decreasing trend with distance was observed. For most of the crustal elements, contamination factors (CF, element concentration in polluted area/element concentration in background area) were low (< 2). For Bi, Cr, Pb, Sn, and Zn, the Iskenderun region was classified as seriously contaminated (8 <  < 27), while for several elements, including Cd, Ag, Cr, As, Fe, Mn, Sn, Mo, Se, Pb, Ni, Sb and Zn the region was classified as moderately contaminated (3.5 < < 8). Sources of trace elements in Iskenderun industrial region were investigated using Principal Component Analysis (PCA). PCA have identified four factors as crustal-resuspended particulate matter, iron-steel plant emissions, marine aerosol, and accumulation of nutrient elements on plants. Spatial variations of anthropogenic-based trace elements supported the finding that iron-steel facilities are their major sources in the Iskenderun industrial region. Results of this study confirmed that tree components and litter can be used as passive samplers to explore the geographical distribution of atmospheric pollution.
某工业区大气污染主微量元素生物监测研究
利用21个工业场地和6个背景场地的树木成分样本(松针、树皮、树枝、茎和凋落物)和土壤样本,通过测量48种主要和微量元素,确定了Iskenderun工业区大气污染的空间变化和来源。元素浓度最高的是工业场所,总体上随着距离的增加呈下降趋势。大部分地壳元素污染因子(CF、污染区元素浓度/背景区元素浓度)较低(< 2),Bi、Cr、Pb、Sn和Zn被划分为重度污染(8 < < 27),而Cd、Ag、Cr、as、Fe、Mn、Sn、Mo、Se、Pb、Ni、Cd、Ag、Cr、as、Fe、Mn、Sn、Mo、Se、Pb、Ni、将Sb和Zn列为中度污染(3.5 < < 8)。采用主成分分析(PCA)对伊斯肯德伦工业区的微量元素来源进行了调查。主成分分析确定了地壳重悬浮颗粒物、钢铁工厂排放、海洋气溶胶和植物营养元素积累四个因素。人为微量元素的空间变化支持了钢铁设施是伊斯肯德伦工业区微量元素主要来源的发现。本研究的结果证实了树木成分和凋落物可以作为被动样本来探索大气污染的地理分布。
