The concentrations of four metals (copper, cadmium, zinc and lead) were quantified in blue crabs (Callinectes sapidus) tissues collected in January, April, June and September at two stations in Mersin Bay, northeastern Mediterranean Sea, using ICP-MS. The metal concentrations in crabs from the two stations differed significantly. The hepatopancreas was the major organ accumulating metals, followed by gill and muscle tissues. Except for lead, the highest concentrations of metals were measured in the hepatopancreas. The hepatopancreas had higher concentrations of all heavy metals (Cu 321.1 ± 4.30; Zn 182.2 ± 3.40; Cd 48.2 ± 2.00) compared to gill (Cu 90.2 ± 1.35; Zn 104.3 ± 2.30; Cd 22.3 ± 3.40) and muscle (Cu 19.1 ± 1.10; Zn 55.1 ± 3.25; Cd 2.5 ± 0.20). Among the metals analyzed, Cu, Zn and Pb were the most abundant in the different tissues while Cd was the least abundant in C. sapidus. Seasonality in the levels of the four metals was determined.The highest concentrations of all metals were observed in the June (Zn 55.1 ± 3.25; Cu 19.1 ± 1.10; Cd 2.5 ± 0.20; Pb 5.1 ± 0.18) compared to all other months (Zn 34.1 ± 3.23; Cu 11.1 ± 1.15; Cd 0.9 ± 0.20; Pb 3.1 ± 0.21).
采用电感耦合等离子体质谱法（ICP-MS）对地中海东北部梅尔辛湾两个采样站1月、4月、6月和9月采集的蓝蟹（Callinectes sapidus）组织中的四种金属（铜、镉、锌和铅）浓度进行了定量分析。两个采样站的蓝蟹体内金属浓度存在显著差异。肝胰腺是积累金属的主要器官，其次是鳃和肌肉组织。除铅外，肝胰腺中金属浓度最高。与鳃（铜90.2±1.35；锌104.3±2.30；镉22.3±3.40）和肌肉（铜19.1±1.10；锌55.1±3.25；镉2.5±0.20）相比，肝胰腺中所有重金属（铜321.1±4.30；锌182.2±3.40；镉48.2±2.00）的浓度更高。在所分析的金属中，铜、锌和铅在不同组织中含量最高，而镉在蓝蟹体内含量最少。测定了四种金属含量的季节性变化。与其他月份（锌34.1±3.23；铜11.1±1.15；镉0.9±0.20；铅3.1±0.21）相比，6月所有金属的浓度最高（锌55.1±3.25；铜19.1±1.10；镉2.5±0.20；铅5.1±0.18）。
