heal.abstract	Acid drainage waters generated in the copper ore deposit Elshitza, Central Bulgaria, were treated by a natural wetland located in the deposit. The water had pH usually in the range of about 2.5-4.0 and contained copper, cadmium, arsenic, iron, manganese and sulphates as main pollutants. The water flow rate varied in the range of about 0.5 to 2.0 1/s. The wetland was characterized by an abundant water and emergent vegetation and a diverse microflora. An efficient removal of the pollutants was achieved in the wetland and their residual concentrations in the wetland effluents were decreased below the relevant permissible levels for waters intended for use in the agriculture and/or industry. The removal was due to different processes but the microbial dissimilatory sulphate reduction and the sorption of pollutants by the organic matter (living and dead plant and microbial biomass) and clay minerals present in the wetland played the main role. Negative effects of the pollutants on the growth and activity of the indigenous plant and microbial communities were not observed.	en
