Assessing Heavy Metal Contamination Risk In Soil And Water Of Kanker District Of Chhattisgarh, India

Abstract

Heavy metal in soil and groundwater, which can have a substantial impact on living organisms due to growth
in industry and commercialization, is one of researchers' main concerns regarding the environment. In the
current study, 10 samples of soil and water were collected from various locations in the Kanker district of
Chhattisgarh, India to assess the degree of metal contamination for Pb, Cd, Ni, Cr, Cu, and As. Metal
contamination levels were calculated using an atomic absorption spectrometer. The average concentration of
all the metals in soil and water was below the permissible levels defined by the European Community (EU),
WHO, and USEPA, which is 50-140 mg/kg in soil. In adults, the Average daily dose of soil was identified
in the following sequence ADDing> ADDderm >ADDinh, whereas a similar pattern was observed for water:
ADDing> ADDderm. According to the health risk assessment, the overall Hazard Quotient and Hazard
Index values were less than 1, indicating that there was a non-carcinogenic risk to individuals through all
three routes of exposure to soil and water. For the carcinogenic risk in Kanker District agricultural soil that is
greater than the permissible limit, or 10-6–10-4. It illustrates that the significant cancer risk caused by these
heavy metals in the study region's soil. The goal of this study was to help through assessing different
pollution indices for scientific administration for commercial operations towards environmental pollution its
connection to ecosystems and human wellness.
