The concentration of trace metals (TMs) in soils and cucumber plants in contaminated and reference sites and their health risk for children and adults were investigated. Plant and soil were sampled through 30 squares distributed equally in six cucumber fields in the two sites. The pollution load index, which is the ratio of the concentration of TMs in contaminated and reference soils, showed extensive accumulation of TMs in contaminated soils. The dry and fresh biomass, and fruit production of cucumbers was significantly reduced under pollution stress. The bioaccumulation factor was > 1 for all investigated TMs, except Cd in the reference and Cd, Cr, Zn and Co in the contaminated site indicating the uptake of the investigated TMs from the soil by the root. In addition, the translocation factor to the stem and leaves was < 1. The daily intake of metal of cucumber fruits grown in contaminated soil was > 1 for Fe in adults, and Pb and Fe in children, indicating a health risk for humans by ingestion of cucumbers, while in reference site it was < 1. Pb, Ni, Cu, Fe and Mn in fruits from the reference site and all TMs except Cr in the contaminated site had a health risk index > 1, indicating a high potential of health hazard to consumers. It is necessary to regularly monitor toxic TMs to prevent their accumulation in the food chain.

污染土壤中种植的黄瓜（Cucumis sativus L.）中的痕量金属浓度及其相关的健康风险

研究了受污染和参考地点的土壤和黄瓜植物中痕量金属（TMs）的浓度及其对儿童和成人的健康风险。通过在两个地点的六个黄瓜田中平均分布的30个正方形对植物和土壤进行采样。污染负荷指数是污染土壤和参考土壤中TMs浓度的比率，表明TMs在污染土壤中大量积累。在污染胁迫下，黄瓜的干燥和新鲜生物量以及水果产量大大减少。除参比中的Cd和污染部位的Cd，Cr，Zn和Co以外，所有被调查的TM的生物蓄积因子均大于1，这表明根部从土壤中吸收了被调查的TM。另外，茎和叶的易位因子＜1。在受污染的土壤中生长的黄瓜果实的金属每日摄入量，成人中的Fe＞ 1，儿童中的Pb和Fe，表明通过摄入黄瓜对人类健康有危害，而在参考部位，其<1。Pb，Ni参照地点和受污染地点除铬以外的所有TM中的水果中的铜，铁和锰的健康风险指数均> 1，表明对消费者的健康危害可能性很高。有必要定期监测有毒的TM，以防止其在食物链中积累。参考地点和受污染地点除铬以外的所有TM中水果中的铁和锰的健康风险指数> 1，表明对消费者的健康危害可能性很高。有必要定期监测有毒的TM，以防止其在食物链中积累。参考地点和受污染地点除铬外所有TM中水果中的铁和锰的健康风险指数均> 1，表明对消费者的健康危害潜力很大。有必要定期监测有毒的TM，以防止其在食物链中积累。
