摘要：The present study was conducted to determine the amount of heavy metalloids/metals in the vegetable and soil supplied with domestic wastewater. Advanced techniques to calculate the enrichment coefficient, health risk index, transfer coefficients and pollution load index were employed. All samples (vegetable and soil) were exposed to a process of wet digestion and metal analysis using an atomic absorption spectrophotometer. The concentrations of all heavy metals determined in the soil were considerably below the maximum permissible limits (MPL) in the study area. However, the concentrations of Mo, As, Mn, Ni and Zn were higher than the MPL in the bitter gourd. Highest enrichment coefficient and transfer coefficient were revealed for Cr and Cd, respectively. Higher level of pollution load index was found for Cd, Pb, Mo, Cu, Co, As and Se suggesting that the quality of the soil in the study area is inappropriate for vegetable growth and agricultural use. Only Co, Fe, Cr and Cu had health risk index below the limit which could be considered safe.
