Abstract : Fishes play a vital role in food and nutritional security for humans as they contain a large amount of protein, several essential micronutrients, vitamins, and mineral salts (calcium, iodine, zinc, iron, and selenium). However, fish can accumulate heavy metals from polluted water bodies and transfer them to humans through the food chain. The objective of our study was to assess the concentration of Lead (Pb) in the organs of Clarias batrachus Manager), Catla catla (catla), and Labeo rohita (rohu) collected from local fish markets of Patna, Bihar. Samples were collected in March 2022. Atomic Absorption Spectrophotometer determined the level of Lead. We observed that the accumulation of Lead ranged from 0.005-0.45n/g. The overall lead
concentration was detected in catla and the lowest in rohu using the ANOVA method. The concentration of lead metal at the Hartali Mod site (0.024 pg/g) for Catla catla was the highest among the other place. The order of the lead concentration in different tissue of catla was in the order brain>gills>muscles>heart>liver. The study showed that lead concentration in these fishes was under the permissible limit. Still, people should be aware of the possible threats as more lead accumulation causes serious health issues.
