In the present study, 18 polychlorinated biphenyl (PCB) compounds were measured in marine sediments collected from 49 offshore stations in the Persian Gulf and the Gulf of Oman in 2019. After the last oceanographic cruise in 2006, no study has been performed on the offshore sediments of this region, and this is the first study on the PCBs in this area. The total amount of PCB compounds in the sediment samples ranged from 74.38 ng kg (near Abu Musa Island) to 1212.98 ng kg (near Siri and Kish Island). The maximum and minimum values of the individual detected PCB compounds were 175.88 ng kg (PCB52) and 2.09 ng kg (PCB156), respectively. The levels of total PCBs detected in sediments were lower than the Canadian interim sediment quality guideline value of 21500 ng kg for marine sediments. The sedimentary mass inventories for ΣPCBs were 0.6 and 0.2 mt for the Persian Gulf and Gulf of Oman, respectively.
在本研究中，2019 年在波斯湾和阿曼湾的 49 个近海站位采集了海洋沉积物，共测量了 18 种多氯联苯（PCB）化合物。自 2006 年最后一次海洋考察以来，该地区的近海沉积物尚未进行过研究，这是该地区首次对 PCB 进行的研究。沉积物样品中 PCB 化合物的总量范围为 74.38ngkg（阿布穆萨岛附近）至 1212.98ngkg（锡里岛和基什岛附近）。单个检测到的 PCB 化合物的最高和最低值分别为 175.88ngkg（PCB52）和 2.09ngkg（PCB156）。沉积物中检测到的总多氯联苯水平低于加拿大海洋沉积物暂定质量指导值 21500ngkg。波斯湾和阿曼湾的ΣPCBs 沉积物质量库存分别为 0.6 和 0.2 公吨。
