摘要：Yousif RA, Choudhary MI, Ahmed S, Ahmed Q2021Review: Bioaccumulation of heavy metals in fish and other aquatic organisms from Karachi Coast, PakistanNusantara Bioscience 13: 74-85Heavy metals are being utilized in a variety of ways in industries, agriculture, food processing and household in many formsMetals are unique environmental and industrial pollutants in the sense that they are neither created nor destroyed by human beings but are only transported and transformed into various productsThe present study deals with the findings of various investigators on the effect of heavy metals on fish and other aquatic organisms on Karachi coasts of PakistanThe polluted areas (Rivers and Karachi coasts) receiving effluents from industrial, agricultural, municipal and domestic wastesThe order of abundance of the metals were as fellow; Fe > Zn > Cu > Mn > Cd > Pb > Cr > Ni > Hg > AsMost studies showed that essential metals (Fe, Zn, Cu, and Mn) in aquatic organisms are much high, but the quantities of non-essential metals are found to be lessThis review has shown that fish and other aquatic organisms are used as bio-monitoring species in heavy metal pollutionIt is suggested that such investigations should be continuous in terms of both human health and determination of metal pollution in aquatic environment.
