In the present study, cadmium and lead concentrations were compared in barnacles, ghost shrimps, polychaetes, bivalves, and sediment from ten different locations along the intertidal zone of the Persian Gulf and the Gulf of Oman. The results revealed significant differences in the heavy metal concentrations between the organisms with barnacles showing, by far, the highest metal concentrations. The bioaccumulation factor of Cd in different animals follows this pattern with barnacles>bivalves>polychaetes>ghost shrimps, while the pattern for Pb was barnacles>polychaetes>bivalves>ghost shrimps. In most of the stations, sediments showed the lowest lead and cadmium concentrations. Therefore, it is concluded that barnacles with Pb concentrations between 0.17 and 2,016.1 μg/g and Cd concentrations ranging from 0.4 to 147.1 μg/g are the best organisms to be employed in monitoring programs designed to assess pollution with bioavailable metals in the Persian Gulf and the Gulf of Oman.
在本研究中，比较了波斯湾和阿曼湾潮间带十个不同地点的藤壶、幽灵虾、多毛类环节动物、双壳类软体动物和沉积物中的镉和铅浓度。结果表明，生物体内重金属浓度存在显著差异，藤壶的金属浓度最高。不同动物的 Cd 生物积累因子遵循藤壶>双壳类>多毛类>幽灵虾的模式，而 Pb 的模式为藤壶>多毛类>双壳类>幽灵虾。在大多数站位，沉积物中的铅和镉浓度最低。因此，结论是，Pb 浓度在 0.17 和 2,016.1 μg/g 之间，Cd 浓度在 0.4 和 147.1 μg/g 之间的藤壶是监测波斯湾和阿曼湾生物可利用金属污染的最佳生物。
