This study is the first detailed ecotoxicological study of the annulated sea snake, Hydrophis cyanocinctus. Concentrations of lead, cadmium, nickel and vanadium were evaluated in muscle, liver, kidney, skin and blood of the annulated sea snake (H. cyanocinctus) and in the whole bodies of its main prey species (Periophthalmus waltoni and Boleophthalmus dussumieri) in the Hara Protected Area, the Persian Gulf. The mean concentrations of lead and vanadium were highest in the kidney, which identified the kidney as a target organ for metals in sea snakes as it is in other reptilian groups. Mean concentrations of cadmium and nickel were highest in the liver and skin, respectively. Mean cadmium concentrations were significantly higher in the liver compared to prey species, which indicated that prey items may be a source of cadmium for the annulated sea snake in the study area. Data presented here may be considered as a baseline for further ecotoxicological studies in sea snakes.
本研究是对环纹海蛇（Hydrophis cyanocinctus）进行的首次详细的生态毒理学研究。在哈腊保护区（波斯湾），评估了环纹海蛇（H. cyanocinctus）肌肉、肝脏、肾脏、皮肤和血液中的铅、镉、镍和钒浓度，以及其主要食物物种（湄公河巨鲶和缘斑鳖）的整体浓度。铅和钒的平均浓度在肾脏中最高，这表明肾脏是海蛇体内金属的靶器官，就像在其他爬行动物群体中一样。镉和镍的平均浓度分别在肝脏和皮肤中最高。与食物物种相比，肝脏中的平均镉浓度明显更高，这表明在研究区域中，食物物种可能是环纹海蛇镉的来源。这里呈现的数据可被视为进一步进行海蛇生态毒理学研究的基准。
