In this research, the levels of polychlorinated biphenyls (PCBs) were investigated in the marine sediments of Asaluyeh harbor, in the Persian Gulf. The samples were taken from industrial, semi-industrial and urban regions. The mean concentration levels of total (Σ) 18 detected PCBs were 514.32, 144.67 and 31.6 pg/g dw for the industrial, semi-industrial and urban sampling stations, respectively. Based on a multivariate statistical analysis, it was found that high contamination levels of PCBs in sediments collected along the Persian Gulf were associated with releases from local industries. Total organic carbon (TOC) content was significantly and positively correlated with the concentrations of PCB congeners. World Health Organization toxic equivalents (TEQs) for PCBs ranged from 0.04 to 2.66 pg TEQ/g dry weight (dw) in the coastal sediments. The TEQ values in this study were higher than many reported worldwide in the literature for sediments. This suggests that there are high levels of contamination in the area due to industrial and other human activities.
本研究调查了波斯湾阿萨卢耶港海洋沉积物中的多氯联苯（PCBs）水平。样本取自工业区、半工业区和城市区域。在工业区、半工业区和城市采样站，所检测到的18种多氯联苯的总浓度水平（Σ）分别为514.32、144.67和31.6 pg/g干重。基于多变量统计分析，发现波斯湾沿岸采集的沉积物中多氯联苯的高污染水平与当地工业排放有关。总有机碳（TOC）含量与多氯联苯同系物的浓度呈显著正相关。沿海沉积物中多氯联苯的世界卫生组织毒性当量（TEQs）范围为0.04至2.66 pg TEQ/g干重（dw）。本研究中的毒性当量值高于文献中全球报道的许多沉积物的毒性当量值。这表明该地区由于工业和其他人类活动而存在高水平的污染。
