Karst water resources, which are extremely sensitive to mining activities, are critical for the support of human societies and ecological systems in many regions worldwide. In order to determine the sources and fate of dissolved sulfate in low-pH karst waters, hydrochemical variations of karst waters with and without acid mine drainage (AMD) impacts were investigated along with stable isotope dynamics...
The use of high fluoride-content coal caused the severe coal-burning endemic fluorosis in Zhijin County, Guizhou Province, China. The long-term mine exploitation in this region is as an important source of acid mine drainage (AMD) and leads to the release of potential fluoride (F−) into the surrounding waters. Aiming to investigate the source, hydrogeochemical characteristics and influencing factors...
