Abstract
Abstract: This study aims to know the concentration of heavy metals in the muscle of three species of edible fish collected from Ramnagar market of Hyderabad city and to assess the possible health risks associated with its consumption. In this study, we used Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) to estimate cadmium (Cd), lead (Pb), and mercury (Hg) in different types of fishes, such as Rohu (Labeo rohita), Roopchand (Piaractus brachypomus) and MilkFish (Chanos chanos). The concentration range of heavy metals in this study is cadmium ranges from 0.04-0.05mg/kg, while lead is between 0.04-0.07mg/kg and mercury is 0.05mg/kg. The permissible limit for cadmium is 0.3mg/kg, lead is 1.5mg/kg and mercury is 0.5mg/kg given by FAO/WHO. By comparing the values obtained in the present study with those of permissible limit values, we can conclude that the consumption of these three fishes from the Ramnagar area does not cause any health risk to humans.
