厦门西港沉积物中多环芳烃的垂直分布特征与污染追踪
The vertical distributions of polycyclic aromatic hydrocarbons and the tracing of pollutants in sediments of Xiamen Bay
Abstract
采用气相色谱对厦门西港1号站和5号站柱状沉积物样中16种多环芳烃（PAHS）进行分离鉴定，结果显示，16种多环芳烃含量的垂直分布范围为158~337ng/g，半定量后的ΣPAHS分布为1.1~6.0μg/g。5号站（位于港湾内）较1号站（位于港口外围区）受PAHS沾污严重，但相比于世界上靠城市的近岸港口，污染则较轻微。厦门西港PAHS主要来源于油类污染及城市工业、生活污水的排放 On the separation and determination of 16 PAHs in sediment cores From two stations(No.1 and No.5)of Xiamen Bay,the concentrations of 16 PAHs are in the range of 158～337ng/g dry weight,and Σ PAHs are in the range of 1 1～6 0μg/g.No.5 station(inside the harbor)is contaminated by PAHs much more than No.1(around the harbor).But the concentrations of PAHs of Xiamen Bay are much lower than the average of those in harbors near coastal cities worldwide.The sourcpollution,urban,industrialized cities discharge and combustion of Fuels.
