Distribution, ecological, health risk of heavy metals in croplands by urbanization
Author(s): Wilma Wilson*
The rapid rise of urbanization and urban services has resulted in the poisoning of urban soils with heavy elements, which has become a serious environmental and human health concern. The effects of urbanization on the combined pollution severity and health risk potential of heavy metals in corn-cultivated urban versus non-urban soils are explored in this study. Enrichment Factor (EF), Ecological Risk (ER), Bio Concentration Factor (BCF), Transmission Factor (TF), hazard index (HI), and Carcinogenic Risk (CR) were used in a multidimensional analysis (CR). The findings show that the concentrations of all metals in urban farmlands have increased significantly. When compared to non-urban soils, EF indicates a significant increase in all metals in the urban soil, downgrading this index from minimal enrichment (EF 2) in control soils to moderate enrichment (EF>2) in urban soils.
