This study investigated the source and magnitude of metal contamination in soils and vegetables collected in the vicinity of the Daye smelter, China. Results showed that soils and vegetables were heavily contaminated by cadmium (Cd) and lead (Pb). The average levels of Cd and Pb in vegetables were 0.21 and 3.28 mg/kg fresh weight, respectively. Community Bureau of Reference (BCR) operational speciation analysis indicated that the source of metals in soils probably resulted from sewage irrigation and contaminated sediment. Transfer and correlation coefficients were also calculated to evaluate the bioavailability of metals to vegetables. This investigation highlights the potential risk to local residents via consumption of vegetables.
本研究调查了中国大冶冶炼厂附近采集的土壤和蔬菜中金属污染的来源及程度。结果表明，土壤和蔬菜受到镉（Cd）和铅（Pb）的严重污染。蔬菜中Cd和Pb的平均含量分别为0.21和3.28毫克/千克鲜重。欧盟标准局（BCR）的操作形态分析表明，土壤中金属的来源可能是污水灌溉和受污染的沉积物。还计算了迁移和相关系数，以评估金属对蔬菜的生物有效性。这项调查突出了当地居民通过食用蔬菜面临的潜在风险。
