- Abstract
The study assess concentration of nine metals in the abiotic (water and sediment) and biotic components (aquatic plant and benthic Rita rita and benthopelagic Ctenopharyngodon idella fish) of River Ganga at Ganga Barrage, Kanpur. Amounts of all elements in river water and aquatic plant exceeded the permissible limit recommended by the world health organization and USEPA except for Zn in the aquatic plant. Heavy metals concentrations in critical organs (kidneys, liver, muscles and gills) of fish were estimated and health risk post consuming contaminated fishes from study area was evaluated through target hazard quotient and hazard index. The result revealed that the children were more prone to health risks than adult by consuming the fish. The geoaccumulation index (Igeo) values were contributed by Cu having value of 1.58 in water and 1.003 in sediments than their desired limit of one. Similarly, Cd also has value of 1.152 in water and Pb have the value above 2 in both water (2.172) and sediment (2.218) reflecting their main contribution in pollution of the Ganga river and its sediments. The contamination factor (CF) and ecological risk (Er) were due to Cd and Pb in Ganga River water and sediment respectively at Ganga Barrage, Kanpur. The pollution load index (PLI) and potential ecological risk index (PERI) values were within the safe levels of the abiotic community.
