摘要

The increasing levels of heavy metals, particularly chromium, in soil and the environment pose a significant threat to human health and the ecosystem. Chromium is known to be carcinogenic and toxic at high concentrations. This study aimed to investigate the effects of chromium toxicity on food crops grown in soil amended with compost made from municipal solid waste (MSW). The research focused on evaluating the potential risks of soil metal toxicity to humans and understanding the transfer of chromium from contaminated soil to food crops. The compost product's heavy metal content was analyzed, and the results showed a significant increase in chromium content in soil and vegetables with increasing MSW application rates. The study revealed a substantial difference in metal concentration between the soils of Coriandrum sativum (Year 2) and Mentha arvensis (Year 1). Among the fifteen vegetables analyzed, Abelmoschus esculentus exhibited the highest concentration of chromium (0.1604 mg/g) at the highest MSW application rate (T3) during both growing years. A cancer risk assessment was conducted, and the results showed a higher cancer risk in A. esculentus at T3 during Year 2. The findings of this study highlight the potential risks associated with the use of MSW compost in agriculture, particularly with regards to chromium toxicity. The results emphasize the need for careful monitoring and management of heavy metal contamination in soil and the environment to ensure the safety of food crops and human health.
