Effect of Heavy Metals on Fishes: Toxicity and Bioaccumulation
Author(s): Pramita Garai, Priyajit Banerjee, Pradip Mondal and Nimai Chandra Saha*
Heavy metal pollution is a serious problem for the environment due to their toxicity, persistency, bioaccumulation,
and bio magnifications property. Heavy metal contamination in the environment can occur from different natural
and anthropogenic sources. The natural sources of heavy metals are mainly volcanic eruption and weathering of
metal-bearing rocks, while the anthropogenic sources of heavy metals include agricultural and industrial activities,
combustion of fossil fuel and gasoline, waste incinerators, mining, etc. The mobilization of these heavy metals to
the aquatic ecosystem alters the physicochemical property of water which is hazardous for aquatic organisms. Heavy
metals mainly enter the fish body through gills, body surface and digestive tract during ingestion of metal accumulated
food materials. Cadmium, chromium, nickel, arsenic, copper, mercury, lead and zinc ar.. View More»
