Abstract
The self-purification potential of rivers contaminated by Acid Mine Drainage (AMD) released from the tailings dump of the Sungun mine (NW of Iran) and the bioaccumulation potential of suspended and floating algae in the rivers were studied. By moving away from the mine and via contact of AMD with limestone pebbles in the riverbed,metal concentrations decrease due to the increase in pH. Dilution due to mixing with other stream brunches also has a considerable effect on natural attenuation. The population density of algae illustrated an adverse relationship with metal concentration and algae showed a high capacity to bioaccumulate metals
