The impact of anthropogenic organic and inorganic pollutants on the Hasdeo River Water Quality in Korba Region, Chhattisgarh, India

Abstract

In the name of development, industries discharge their wastewater, which contains different Metallic species and massive organic load into the next-door river system. In this study, we assess the impact of organic and inorganic contaminations on Hasdeo River at Korba region, which is fifth critically polluted city in India. Hear, a new approach for water quality indexing like Water quality index (WQI), Heavy metal pollution index (HPI) and metal index (MI) has been proposed to represent pollution due to heavy metals in river system. The sample's pollution parameters and heavy metals contamination is exceed from BIS or WHO standards of drinking water (all p<0.05). WQI shows that the entire water samples are not suitable for drinking and aquatic life but they are safe only for irrigation. HPI and MI calculation revels that more than 95% sampling sites are critically polluted with heavy metals. Thus, a high level of industrialization deterioration of river water quality is recorded for adequate action.

India has been blessed huge amount of surface water in the form of rivers. In the name of development, Industries discharge their treated or partially treated wastewater, which contains different Metallic species and massive organic load into the next-door river systems [1, 2]. Not only do these pollutants caused aquatic ecosystem disturbance; but also some of them (pb, cd, cr, etc.) subsequently enter the food chain, and threaten human health by poisoning and accumulating in benthos, aquatic plants and other upper level of animal hierarchy [3-5].
