摘要: Carboniferous activity generates acid mine drainage (AMD) which is capable of unleashing toxic effects on the exposed biota. The aim this study was to evaluate and genotoxic potential untreated-AMD AMD treated with calcinated sediment, using physicochemical parameters bioassays. Results revealed that presented low pH values elevated concentrations metals Fe, Al, Mn, Zn Cu. High acute toxicity observed in Artemia sp. Daphnia magna, sub-chronic genotoxicity Allium cepa L. as well scission plasmid DNA untreated-AMD. Treatment sediment promoted reduction acidity removal metals, a effects. In conclusion, can be used an alternative treatment.
