The aim of the present study was to assess the concentration of potentially toxic metals (PTMs) like As,Cd, Cr, Cu, Fe and Pb in the Damsal Nala of Sukinda Chromite Valley, Jajpur of Odisha (India) and its subsequenthistopathological lesions in the fish Puntius sophore. Energy Dispersive X-Ray Fluorescence (EDXRF) and FlameAtomic Absorption Spectroscopy (FAAS) methods were used to evaluate the concentrations of PTMs in the musclesof fish, Puntius sophore collected from different zones namely upstream discharge zone (UDZ) and upstream zone(UZ) of the Damsal Nala and control water bodies (CW). In the UDZ of Nala, the concentration of metals viz., Cd, Pband Fe were 2 to 7 times, and Cr was 77 times higher than the maximum permissible limits recommended by WHOand FAO in the fish muscles. The values of Target Hazard Quotients (THQ) of all these 6 metals were <1 in CW andUZ, but in UDZ the THQ values of Cr and Fe were >1. Hazard Index (HI) for UDZ was 3.47, indicated the alarmingconcentration of metal which can pose serious risk to human health. Histopathological observations in liver andkidney of Puntius sophore collected from UDZ demonstrated the serious lesions, but mild damage in fish collectedfrom UZ. These histological alterations and the health risk indices disclosed the effects of effluents of chromitemining and the impact on the ecological balance which may result into health hazards to the local human populationwho are maintaining their livelihood by consuming these fish as protein source.
