Abstract

The Present investigation aimed to examine the heavy metal concentrations in water samples from seven locations in the Bhosga Reservoir provided critical insights into water quality and potential environmental impacts. The metals assessed included Zinc (Zn), Copper (Cu), Manganese (Mn), Chromium (Cr), Lead (Pb), Cadmium (Cd), and Nickel (Ni). Results indicated that Zinc concentrations well within the WHO limit of 15 mg/L. Copper levels remaining below the WHO standard of 1.5mg/L, though elevated levels at some sites raised concerns about localized pollution. Manganese concentrations were also below the WHO standard of 0.3 mg/L. Chromium was found to be within safe limits. In contrast, Lead concentrations exceeded the WHO limit of 0.01mg/L, raising serious environmental concerns. Cadmium levels were exceeding the permissible limit of 0.003 mg/L at multiple sites. Nickel concentrations were surpassing the WHO acceptable limit of 0.02 mg/L at several stations. In summary, the highest to lowest concentrations detected were as follows: Cu>Mn>Pb>Ni>Cd>Cr>Zn. These ranking underscores the varying levels of contamination across the sites, with copper and manganese exhibiting the highest concentrations, raising potential environmental concerns.

Full Article/Conclusion

The present study reveals that many metals are found within permissible limits, significant exceedances are noted particularly for Lead (Pb), Cadmium (Cd), and Nickel (Ni) at several sites, especially A2 and A1. These findings indicate that while the overall water quality may seem acceptable for certain metals, the presence of these hazardous contaminants raises concerns about environmental and public health implications.
