摘要

Heavy metal contamination of water resources significantly impacts water quality. This study assesses heavy metal concentrations along the Periyar’s industrial belt through 14 surface water samples and 14 riverbank soil samples analysed by inductively coupled plasma optical emission spectroscopy (ICP-OES). The results reveal high concentrations of lead (Pb) and zinc (Zn) in surface waters that exceed aquatic life standards. The study also reports high levels of zinc (Zn) and nickel (Ni) in riverbank soils. Ecological and biological risk assessments indicate extreme risks from cadmium (Cd) in surface water and nickel (Ni) in soil, highlighting considerable health risks through both carcinogenic and non-carcinogenic assessments. Notably, the hazard index for soil surpasses that of surface water and nickel (Ni) which poses a significant carcinogenic risk. The results suggest significant pollution in the Periyar River, exceeding established regulatory thresholds, with heavy metals playing a prominent role in its deterioration. Sustained efforts in pollution management and broader environmental considerations are critical in restoring this essential resource and thereby sustaining livelihoods.
