The hydrogeochemistry of the Wujiang river drainage system in Guizhou, China (I) - U-Ca-Sr system in karst river water

摘要

Trace element concentrations in river water are controlled by a number of factors, such as lithology, weathering pocesses or adsorption. Further investigations on trace elements, especially heavy and transition metals, allow us to evaluate the impact on the environment by human activities. Chinese scholars focus their research on the geochemistry of river water of the Chinagjiang River and Huanghe River. A number of scholars have conducted research on the uranium geochemistry in river water in order to know the variation of input of U from rivers to oceans, and to get better understanding of the geochemistry of uranium series in marine geochemistry.
