Acid mine, drainage (AMD), generated by the biological oxidation of metal sulfides to metal sulfates in ,mine, wastes, is characterized by low pH and high concentrations of dissolved metals and sulfates (Peng et al. 2017). AMD is extremely toxic to aquatic organisms because of its strong acidity and the solubilization of metals (Peng et al. 2017).
