Phytoremediation Potential of Plants for Heavy Metal Contaminated Soil

Abstract

This research looks at how some plant species' development and metabolic characteristics are affected by heavy metal pollution in mining soils. Two mining sites provided soil samples, which were compared to control soil from a university campus. The growth, protein, carbohydrate, and proline content of the chosen species—Sorghum bicolor, Vigna mungo, Eleusine coracana, Brassica juncea, and Telfairia occidentalis—were assessed in a greenhouse environment. The findings showed that plants growing in polluted soils had lower amounts of protein and carbohydrates, and that Vigna mungo and Sorghum bicolor were more resistant to metal stress. In polluted soils, elevated proline buildup indicated a stress reaction. The research emphasizes the detrimental effects of heavy metal pollution on plant health and raises the possibility that tolerant species might be useful in phytoremediation.
