Abstract

This research paper presents a polarographic analysis of heavy metal contamination in soil samples from the marble industry in Kishangarh, Ajmer, Rajasthan. The study focuses on evaluating the concentrations of lead (Pb), cadmium (Cd), chromium (Cr), and zinc (Zn) using polarographic techniques, with the aim of understanding the extent of soil pollution and its implications. Soil samples were collected from various distances around marble processing units, revealing elevated levels of Pb, Cd, Cr, and Zn, which are concerning given their potential health and environmental impacts. Average concentrations of Pb were found to be 52 ppm, Cd 2.8 ppm, Cr 30 ppm, and Zn 102 ppm, exceeding established soil quality standards for Cd and Zn, and nearing limits for Pb and Cr. The spatial distribution of heavy metals indicated that contamination is most severe near processing units, decreasing with distance. The findings highlight significant environmental concerns, underscoring the need for effective pollution control measures and regular monitoring. Recommendations include implementing advanced pollution control technologies, developing soil remediation strategies, and engaging in community awareness programs. This study provides crucial data for environmental management and policy development aimed at mitigating the impact of industrial activities on soil quality.
