Environmental assessment of chromium in soil using atomic absorption spectroscopy

Heavy metal contamination in soil is a major environmental concern caused by industrial, agricultural, and mining activities, leading to the accumulation of toxic elements like chromium. This study highlights the use of Atomic Absorption Spectroscopy (AAS) as a reliable and sensitive technique for detecting chromium in soil samples collected from agricultural, roadside, and mining areas. The samples were properly prepared through acid digestion to ensure accurate analysis. Results showed higher chromium concentrations in contaminated sites, indicating potential risks to ecosystems and human health. AAS proved effective due to its precision and reproducibility, though it requires careful sample handling. Overall, the study emphasizes the importance of continuous monitoring, pollution control, and remediation strategies to manage soil contamination and protect environmental and public health.
