Human risks increase by consuming plants growing in trace/heavy metals contaminated soil irrigated with polluted water. The present study aims to assess the ability of common mallow to accumulate trace/heavy metals from polluted soils at South Greater Cairo, Egypt; and their hazardous effects on consumer’s health. Five quadrats were used to collect soil and plant samples from three sites of un-polluted and polluted fields for chemical analysis and measurement of growth variables, as well as for assessing the daily intake of metals (DIM) and hazard quotient (HQ). Irrigation water analysis showed elevated concentrations of the investigated metals and mineral salts in the polluted area compared with the un-polluted one. Plant samples showed reduction in their growth parameters; as well as pigments and nutrient content in the metal-contaminated soil. In addition, Pb, Cd, Cu, Ni, Fe, Mn, Zn, and Co concentrations in the shoots and roots of plants grown in polluted fields were higher compared with plants grown in un-polluted site. The bioaccumulation and translocation factors of most investigated metals indicated the great ability of common mallow to accumulate such metals, which would increase the human intake of metals in their daily diets compared to their reference values (R_fD). The hazard quotient (HQ) of Pb, Cr, Fe, Mn and Zn for children and Pb, Cd, Fe and Mn for adults was >1, indicating health hazards for the consumers of common mallow cultivated in the polluted area.

食用生长在被污水灌溉的痕量/重金属污染土壤中的植物会增加人的风险。本研究旨在评估埃及南部大开罗南部普通锦葵从污染土壤中积累痕量/重金属的能力。及其对消费者健康的危害。使用五个样方从三个未污染和污染领域的地点收集土壤和植物样品，以进行化学分析和测量生长变量，以及评估每日的金属摄入量（DIM）和危险商（HQ）。灌溉水的分析表明，与未污染的土壤相比，在污染区域中被调查的金属和矿物盐的浓度升高。植物样品显示其生长参数降低；以及金属污染土壤中的色素和养分含量。此外，与在未污染地区种植的植物相比，在污染地区种植的植物的茎和根中铅，镉，铜，镍，铁，锰，锌和钴的浓度更高。大多数被调查金属的生物蓄积和转运因子表明普通锦葵具有很高的蓄积这种金属的能力，与参考值相比，这将增加人类日常饮食中金属的摄入量（R_f D）。儿童铅，铬，铁，锰和锌与成人铅，镉，铁和锰的危害商（HQ）> 1，表明在污染地区种植的普通锦葵对消费者的健康危害。
