Human Health Hazard due to Metal Uptake via Fish Consumption from Coastal and Fresh Water Waters in Eastern India Along the Bay of Bengal

Human Health Hazard due to Metal Uptake via Fish Consumption from Coastal and Fresh Water Waters in Eastern India Along the Bay of Bengal

Concentrations of copper, zinc, manganese, and iron were determined in muscle tissue of coastal fish (Pumpus argentius, Tenulosa ilisha and Rastrelliger kanagurta) and fresh water fish (Hypophthalmichthys molithrix and Cirhinnus mrigela) samples from West Bengal, India, for assessing the potential health risk to human population. The concentrations of Cu, Zn, Mn and Fe in coastal fish muscles were ranged between 0.79-4.0 mg kg-1 dw, 5-29 mg kg-1 dw, 0.50-5.0 mg kg-1 dw and 20-75 mg kg-1 dw, respectively, and in fresh water fish, they were in the ranges of 5.0-28 mg kg-1 dw, 33-51 mg kg-1 dw, 2.0-6.0 mg kg-1 dw and 38- 110 mg kg-1 dw, respectively. The pattern of metals accumulation was in order of Fe > Zn > Cu > Mn. The results showed that the concentrations of metals in studied fish muscles were all lower than recommended guideline values.
