Arsenic (As) can be transferred from soil and accumulated in food plants. So far, we have a knowledge gap about transference of As from agricultural soils to wheat plant in the natural polluted environment. The aim of present study was to investigate As transfer from soil to different tissues of wheat at a highly As polluted area. In this regard, the mobility indices were used to explain As transfer and accumulation from soil to wheat plant. Moreover, the relationships between soil properties including soil As content, pH, cation‐exchange capacity (CEC), electrical conductivity (EC), organic matter (OM), Fe, and Al percentage with As concentrations in wheat root, straw, and grain were investigated. Finally, the potential health risks of As exposure to humans through consumption of the local wheat crops were assessed. According to the results, harmful degree of As was accumulated in different parts of wheat plant. The impact of different soil properties on As accumulation in wheat was found to be as follows: soil As content > Al% > Fe% > OM > pH > CEC > EC. High carcinogenic and noncarcinogenic risks in all age groups of consumers were found. The minimum and maximum values for target hazard quotient and excess lifetime cancer risk were found to be 1.22, 102.97 and 0.000061, 0.33, respectively. These findings strongly support the notion that As can be entered to food chain through agricultural products cultivated in polluted soils.

砷从高污染农田向小麦的迁移：土壤-植物转移模型和健康风险评估

砷（As）可以从土壤中转移并积聚在食用植物中。到目前为止，我们在自然污染环境下关于从农业土壤向小麦植物中砷转移的知识空白。本研究的目的是研究在高As污染地区As从土壤向小麦不同组织的转移。在这方面，迁移率指数用来解释砷从土壤到小麦植物的转移和积累。此外，小麦根，秸秆和谷物中土壤砷含量，土壤pH，阳离子交换容量（CEC），电导率（EC），有机质（OM），铁和铝百分比与土壤特性之间的关系被调查了。最后，评估了通过食用当地小麦作物而使砷暴露于人类的潜在健康风险。根据结果​​，有害程度的砷积累在小麦植株的不同部位。研究发现，不同土壤性质对小麦砷积累的影响为：土壤砷含量> Al％> Fe％> OM> pH> CEC> EC。在所有年龄段的消费者中都发现了高致癌和非致癌风险。目标危险商和终生癌症风险的最小值和最大值分别为1.22、102.97和0.000061、0.33。这些发现强烈支持了砷可以通过在污染土壤中种植的农产品进入食物链的观点。在所有年龄段的消费者中都发现了高致癌和非致癌风险。目标危险商和终生癌症风险的最小值和最大值分别为1.22、102.97和0.000061、0.33。这些发现强烈支持了砷可以通过在污染土壤中种植的农产品进入食物链的观点。在所有年龄段的消费者中都发现了高致癌和非致癌风险。目标危险商和终生癌症风险的最小值和最大值分别为1.22、102.97和0.000061、0.33。这些发现强烈支持了砷可以通过在污染土壤中种植的农产品进入食物链的观点。
