The concentration of 23 metals was analyzed in the tissue of nine fish species, which represents the different habitats, i.e., primary feeder, tertiary feeder, and bottom feeder in fresh and marine waters of Visakhapatnam. Scomberomorus guttatus, Upeneus vittatus, and Penaeus indicus were selected in the coastal waters; Xiphias gladius, Stolephorus indicus, and Penaeus monodon from deep sea; and Channa striata, Puntius chola, and Macrobrachium rosenbergii from freshwater were analyzed. Metals in fish were analyzed by using the Inductive Couple Plasma Mass Spectrometer (ICP-MS). The concentrations of metals in fish were within the permissible limit set by WHO, FAO apart from Chromium, Aluminum, Manganese, and Arsenic. The concentrations were highest in coastal water fish and lowest in freshwater fish. Similarly, higher concentrations were observed in bottom feeders than in other tiers.
分析了9种鱼类组织中23种金属的浓度，这些鱼类代表了不同的栖息地，即在维沙卡帕特南的淡水和海水中的初级捕食者、三级捕食者和底栖捕食者。在沿海水域选取了斑点马鲛、条纹副绯鲤和印度对虾；从深海选取了剑鱼、印度棱鳀和斑节对虾；对来自淡水的条纹鳢、乔氏无须魮和罗氏沼虾进行了分析。采用电感耦合等离子体质谱仪（ICP-MS）分析鱼类中的金属。除铬、铝、锰和砷外，鱼类中金属的浓度在世界卫生组织、联合国粮食及农业组织规定的允许限度内。沿海水域鱼类中的浓度最高，淡水鱼类中的浓度最低。同样，底栖捕食者中的浓度高于其他层级。
