This study focuses on creating baseline for U, U, U, Pb, Po and K concentrations in the northern Arabian Gulf. The respective concentration ranges were 0.047-0.050, 0.00186-0.00198, 0.054-0.057, 0.00085-0.00092, 0.00051-0.00062 and 18.6-19.1Bql. These results suggest that the levels are generally comparable to other marine waters in the northern hemisphere. There were no hot spots observed from oil and gas industry. These data will serve as a baseline to gauge possible future inputs of TENORMs in the northern Gulf. A positive and linear correlation was observed between U, K isotopes and seawater salinity. The results also suggest significant fractionation between Po and Pb, attributed to rapid removal of Po by biota compared to Pb. The mean residence time for Po in the study area was 371days. The U/U and U/U activity ratios in seawater samples vary between 1.14-1.15, and 0.038-0.040. The U/U and U/U ratio is similar to the expected composition of seawater (1.148±0.002) and 0.0462.
本研究旨在为阿拉伯湾北部的 U、U、U、Pb、Po 和 K 浓度建立基准。相应的浓度范围分别为 0.047-0.050、0.00186-0.00198、0.054-0.057、0.00085-0.00092、0.00051-0.00062 和 18.6-19.1Bql。这些结果表明，这些水平与北半球其他海洋水域的水平大致相当。没有观察到来自石油和天然气工业的热点。这些数据将作为衡量未来北部海湾 TENORM 可能输入的基准。U、K 同位素与海水盐度之间存在正线性相关。结果还表明，Po 和 Pb 之间存在显著的分馏，这归因于 Po 比 Pb 更快地被生物群去除。Po 在研究区域的平均停留时间为 371 天。海水中 U/U 和 U/U 活度比在 1.14-1.15 之间变化，0.038-0.040。U/U 和 U/U 比值与海水的预期组成（1.148±0.002）和 0.0462 相似。
