So arsenic are easily available to fish, resulting in considerable amount of metal accumulation in the fish tissue. Relationship between metal accumulation in fish organs and in water has been studied in field and laboratory. So we have tried to carry out the survey in effective district of West Bengal, newspaper and published research papers in pummed. The toxic effect due to arsenic on the importance organs of fishes like Gills, Liver, Kidney and Flesh.
