海底热液蚀变火成岩和泥岩中通常富含砷,从岩石堆溶出的砷可能污染周围的土壤和地下水。自2003年日本强制实施土壤污染防治法后,废石中大量低浓度污染物就受到了广泛关注。T.Igarashi等研发了通过控制地球化学条件降低浸出液中砷浓度的方法。通过浸出试验,确定了混合时间、溶液 Submarine hydrothermal alteration igneous rocks and mudstone are generally rich in arsenic, and the arsenic dissolved from the rock pile can contaminate the surrounding soil and groundwater. Since Japan enforced the Soil Pollution Control Law in 2003, a great deal of attention has been paid to a large number of low concentration pollutants in waste rock. T. Igarashi et al. Developed a method to reduce the concentration of arsenic in leachate by controlling geochemical conditions. Through the leaching test, the mixing time and solution were determined
