The concentrations of heavy metals (cadmium (Cd), copper (Cu), nickel (Ni), lead (Pb) and zinc (Zn)) were measured in hepatopancreas and muscle of a commercial shrimp (Metapenaeus affinis), in the muscle, liver and gills of two fish species (Thryssa vitrirostris and Johnius belangerii) and in the sediment samples taken from the mouth of the Arvand river, Meleh estuary and Musa estuary in the northeast Persian Gulf. Concentration of heavy metals varied depending on different tissues, species and sampling sites. Liver of fish and hepatopancreas of shrimp exhibited higher metals' concentration than the other tissues. Generally, in the mouth of the Arvand river, the highest concentration of metals was found in benthic species; while in the mouth of Musa estuary, the highest level of the metals was found in pelagic fish species. Bioaccumulation factors were observed to follow the order: J. belangerii-liver-Cd > T. vitrirostris-liver-Pb > M. affinis-hepatopancreas-Zn >M. affinis-hepatopancreas-Cu >M. affinis- hepatopancreas-Ni. The analysed heavy metals were found in sediment samples at mean concentration in the sediment quality guideline proposed by National Oceanic and Atmospheric Administration (NOAA) and Regional Organization for the Protection of The Marine Environment (ROPME), except for Ni concentration in some cases.
测定了商品虾（近缘新对虾）肝胰腺和肌肉、两种鱼类（玻璃梭鲃和贝氏乔氏鱼）的肌肉、肝脏和鳃以及从波斯湾东北部的阿尔万德河口、梅莱赫河口和穆萨河口采集的沉积物样本中重金属（镉（Cd）、铜（Cu）、镍（Ni）、铅（Pb）和锌（Zn））的浓度。重金属浓度因不同组织、物种和采样地点而异。鱼类的肝脏和虾的肝胰腺中的金属浓度高于其他组织。一般来说，在阿尔万德河口，底栖物种中的金属浓度最高；而在穆萨河口，中上层鱼类中的金属含量最高。观察到生物累积因子的顺序为：贝氏乔氏鱼-肝脏-镉＞玻璃梭鲃-肝脏-铅＞近缘新对虾-肝胰腺-锌＞近缘新对虾-肝胰腺-铜＞近缘新对虾-肝胰腺-镍。除某些情况下镍的浓度外，分析的重金属在沉积物样本中的平均浓度均在国家海洋和大气管理局（NOAA）以及保护海洋环境区域组织（ROPME）提出的沉积物质量准则范围内。
