Assessment of Heavy Metal Ions from Jawaharlal Nehru Autonagar Industrial Effluents and its Impact on Groundwater in Vijayawada

Abstract

Heavy metal pollution has become a major concern in many industrial regions due to its potential harmful effects on the environment and human health. The mining, metal plating, and electronics industries generate aqueous waste containing heavy metal ions (113). If these heavy metal ions are released into the environment, they pose a serious threat to groundwater quality. Heavy metal ions may have detrimental effects on ecosystems and human health in addition to their toxicological characteristics. For the first time, the levels of some heavy metals in water in Vijayawada's Jawaharlal Nehru Autonagar industrial area (JNA) were examined by UV-Vis spectrophotometer. This analysis revealed the levels of Cr, Pb, Hg, Zn, Ni, and Cu ions in JNA industrial effluents. The analysis's findings show that the national water quality guidelines (113) for chromium (1.81-2.63), lead (0.08-0.16), and nickel (1.57-1.75) mg/L are exceeded, endangering both human health and the environment. Furthermore, the study discovered that the heavy metal ions present in the industrial effluents had a direct impact on the groundwater quality of the surrounding area. The presence of heavy metal ions in groundwater chromium (0.04-0.09) mg/L, lead (0.011-0.017) mg/L and nickel (0.037-0.06) mg/L were found to be exceed the IS 10500 drinking water standards, can have a variety of negative consequences. These effects include ecosystem degradation, biodiversity loss, and negative impacts on human health.
