通过对贵州喀斯特地区乌江流域河水中溶解态铀的地球化学研究 ,定量评估了乌江河水中溶解态铀的浓度及河水中溶解态铀进入长江的通量 ( 1 4 74× 1 0 2 mol/a)。结果表明 :乌江流域溶解态铀主要来源于碳酸盐岩风化 ,人类活动对乌江河水中溶解态铀的影响很小。
Through the geochemical study on the dissolved uranium in the river water in the Wujiang River basin in Guizhou Karst area, the concentrations of dissolved uranium and the flux of dissolved uranium into the Yangtze River in the Wujiang River were quantitatively evaluated (1474 × 102 mol / a ). The results show that the dissolved uranium in the Wujiang River Basin mainly comes from the weathering of carbonate rocks and the human activities have little effect on the dissolved uranium in the Wujiang River.
