Following earlier reports of water contamination and arsenic (As) toxicity symptoms in residents of Kurdistan Province, As was determined in rock, soil and plant samples to investigate its fate from rock to crops and its potential effects on human health. Total As content ranged from 4.9 to 10,000 mg/kg, 7.7-430 mg/kg and < 0.05-25,079 µg/kg (dry weight) in rock, soil and plant samples, respectively. The Qorveh-Bijar region data indicated that magmatic differentiation has enriched late magmatic fluids in As. High rare earth elements concentration, dissociation coefficient, and positive Eu anomaly in volcanic rocks, indicated the prevalence of intermediate to felsic composition. The highest As concentration was measured in travertine. In soil, As average level in Qorveh and Bijar was 48.5 and 107 mg/kg, respectively. Higher pollution index and geoaccumulation index (Igeo) were also calculated for Bijar County. The As concentration in crop samples was greater than the recommended maximum permissible concentration for foodstuff. Mann-Whitney U test revealed significant differences between As concentration in different plant species and no difference between plants in Bijar and Qorveh. Also, alfalfa displayed the highest biological accumulation coefficient among the investigated plants. The calculated chronic daily intake of As in Bijar County was higher than the recommended levels for wheat and barley grains. Moreover, the hazard quotient (HQ) and incremental lifetime cancer risk assessments revealed high non-cancer (HQ > 1 for both adults and children) and cancer (particularly for barley in Bijar) risks for inhabitants via consumption of As contaminated crops cultivated in the study area.

伊朗西部岩浆-变质带中岩石-土壤-植物系统中的砷及相关健康风险。

继先前有关库尔德斯坦省居民的水污染和砷（As）毒性症状的报道之后，在岩石，土壤和植物样本中确定了As，以调查其从岩石到农作物的命运及其对人体健康的潜在影响。岩石，土壤和植物样品中的总砷含量分别为4.9至10,000 mg / kg，7.7-430 mg / kg和<0.05-25,079 µg / kg（干重）。Qorveh-Bijar地区的数据表明，岩浆分异作用丰富了As中的晚期岩浆流体。火山岩中稀土元素的浓度高，离解系数高，正Eu异常，说明中等至长英质成分普遍存在。在钙华中测量到最高的As浓度。在土壤中，Qorveh和Bijar的As平均水平分别为48.5和107 mg / kg。还为Bijar县计算了较高的污染指数和地质累积指数（Igeo）。作物样品中的砷浓度大于建议的食品最大允许浓度。Mann-Whitney U检验表明，不同植物物种中的As浓度之间存在显着差异，而Bijar和Qorveh中的植物之间没有差异。此外，苜蓿在研究的植物中显示出最高的生物积累系数。比哈尔县（Bijar County）的As的慢性每日摄入量经计算高于小麦和大麦籽粒的建议水平。此外，危险商（HQ）和终生终生癌症风险评估显示，非癌症的发生率很高（HQ>
