这项研究的重点是确定伊拉克南部Al-Batin地区地下水中铀(U)的浓度、形态、空间分布和潜在来源。虽然很少有研究报道Al-Batin冲积扇部分地区地下水中铀的浓度升高，但到目前为止，对整个扇区地下水中铀的全面调查仍然是空白。为了实现这一目标，收集了43个地下水样本，用于主要阳离子和阴离子、微量元素、总有机碳和总无机碳的分析。U浓度变化范围为0.1~98µg/L，算术平均值为16µg/L。地下水中U的空间分布呈向东和向东北方向增加的趋势，但也有异常。根据PHREEQC模拟，UO2(CO3)(2)(2-)、UO2(CO3)(3)(4-)和UO2(HPO4)(2)(2-)是主要的U物种。Spearman相关分析(n=43，p
This study focuses on identifying concentrations, species, spatial distribution and potential sources of uranium (U) in groundwater in Al-Batin area south of Iraq. Although few studies reported elevated concentration of U in groundwater in some parts of the Al-Batin Alluvial Fan, a comprehensive investigation of U in the groundwater of the entire fan is still missing so far. To achieve this goal, 43 groundwater samples are collected for major cations and anions, trace elements, total organic carbon and total inorganic carbon analyses. U concentrations range between 0.1 and 98 mu g/L with an arithmetic average of 16 mu g/L. The spatial distribution of U in groundwater shows an increase eastward and northeastward with some anomalies. UO2(CO3)(2)(2-), UO2 (CO3)(3)(4 -) and UO2(HPO4)(2)(2-) are the dominant U species according to PHREEQC simulations. Spearman correlation analysis (n = 43, p
