Concentrations of trace elements (arsenic, cadmium, mercury, and lead) in tissues (muscle, gills, and digestive gland) of three commercially exploited crustaceans (Portunus sanguinolentus, Charybdis natator, and Penaeus semisulcatus) and three cephalopods (Doryteuthis sibogae, Sepia pharaonis, and Cistopus indicus) were examined. The animals were captured in the waters of Thoothukudi, and the tissues of six individuals of each species were analyzed using ICP-MS. The highest concentrations of arsenic (16.5 μg/g) and mercury (0.052 μg/g) were recorded in the digestive gland of C. natator, and cadmium (69.9 μg/g) and lead (0.351 μg/g) in the digestive gland of S. pharaonis. The edible portion of the crustaceans and cephalopods contained lower concentrations of trace elements, and these were below allowable limits set by the European Union. The edible parts of the investigated samples are safe for human consumption, but accidental contamination of the edible tissues with material from the digestive glands could lead to concerns relating to metal toxicity.
检测了三种商业开发的甲壳类动物（赤𫚉、沙蟹和日本对虾）和三种头足类动物（短蛸、乌贼和印度枪乌贼）的组织（肌肉、鳃和消化腺）中的微量元素（砷、镉、汞和铅）浓度。这些动物是在杜蒂戈林水域捕获的，使用 ICP-MS 对每个物种的 6 个个体的组织进行了分析。在沙蟹的消化腺中记录到最高浓度的砷（16.5μg/g）和汞（0.052μg/g），而在乌贼的消化腺中记录到最高浓度的镉（69.9μg/g）和铅（0.351μg/g）。甲壳类和头足类动物的可食用部分含有较低浓度的微量元素，这些都低于欧盟设定的允许限量。所研究样品的可食用部分可安全供人类食用，但食用组织偶然受到来自消化腺的物质污染可能会引起对金属毒性的关注。
