【摘要】 选择江苏徐州城市生态系统中水、土、植物等不同环境介质进行多环芳烃的定量分析,研究并探讨了多环芳烃在城市环境中的地球化学特征。研究结果显示:多环芳烃在徐州土壤、地表水、地下水以及生长作物中均广泛存在,主要集中在以钢铁厂为中心的城区约20 km2范围内。由此提示人们:由大量工业活动等人为因素造成的徐州城市环境有机污染不容忽视。更多还原

【Abstract】 The concentrations of polycyclic aromatic hydrocarbon(PAHs) compounds in soil,water and plant samples collected from the urban area of Xuzhou in Jiangsu Province were quantitatively measured,and geochemical characteristics of these compounds in the urban environment of Xuzhou were studied.The results show that PAHs are widely distributed in soil,rivers,underground water and plants of Xuzhou and especially concentrated in the surrounding area of the Xuzhou steel factory.It is considered that the environmental organic pollutants caused by industry activities in Xuzhou urban area cannot be ignored.更多还原
