Evaluating The Histopathological Studies In Native Fishes Thriving In The Coal Mining Areas Of Jharkhand - A Case Study

Abstract

Coal mining generates huge quantity of toxic effluent which consistently pollutes the neighboring wetlands where the local inhabitants regularly cultivate edible fishes. The current study aims to Estimated daily intake of heavy metals by fish and its correlation on human health. The 5 Samples were collected from Konar Dam (S1), Maithon Dam (S2), Panchet Dam (S3), Tenughut Dam (S4) and Tilaya Dam (S5) near Damodar River basin, Jharkhand (india). Mainly P. indicus, M. gulio, P. conchonius, L. calbasu, L. rohita, and L. bata Fish species were collected. Fish species P. indicus (F1), M. gulio (F2), P. conchonius (F3), L. calbasu (F4), L. rohita (F5), and L. bata (F6) are Pb, Co, Cd, and As found at low dietary intake. The maximum EDI observed only accounts for 0.11 µg/kg for F1 at dam 3, 0.35 µg/kg for F3 at dam 3, 0.22 µg/kg for F3 and F6 at dam 2, and 0.17 µg/kg for F1 at dam 3, respectively. The accumulation of heavy metals in tissues appears to cause remarkable histopathological alterations in skin, gills, liver and kidney that might be leading to deleterious effect on fish physiology and consequently impact the consumers of such fishes. The risks to our health and the environment posed by coal mining are ruining our lives. Surface water and sedimentation are found to be correlated, and the histopathology's scanning electron microscopy is also acquired.
