Investigation of heavy metals accumulation in Shikaripara stone mines

Abstract The study aimed to evaluate harmful compound levels in Shikaripara stone mines’ cultivated land, which is renowned for stone quarrying in Jharkhand, India. Sixteen samples were collected from the mines in Dumka district, each at varying distances from the others. The soil samples contain Pb, As, Zn, Mn, Cd, Cu, Hg, and Fe. An Inductively Coupled Plasma-Mass Spectrometer was used to determine the total concentrations of the metals (ICPMS). Calculations of the Enrichment Factor (EF), Geo-accumulation Index ( I geo ), Contamination Factors (CF), Pollution Load Index (PLI), Nemerow Index, and ecological Risk Index (RI) PLI, RI, and Nemerow Index values, considering various toxic substances’ effects on soils overall, revealed significant metal contamination in 50 % of the sampled areas. Agricultural soils exhibited significant contamination with Cu, As, and Zn as a result of nearby copper mining activities. Results advocate regular soil examination and efficient management to reduce metal pollution. Compared to other areas, contamination levels in the study region are relatively lower, emphasizing the need for continued monitoring and management. The report delves into ecological services, assessing the impacts of plastic particles and heavy metals. It sets the stage for further research on the combined effects of these substances and plastic debris on biodiversity.
