    Sammanfattning : The redistribution of metals from point sources (sulphidic mine waste) is presented in this thesis. The impact on surface water systems is determined from water quality and sediment data. It is generally found that lakes act as sinks for the metals, to a different extent for eachmetal. LÄS MER

    Sammanfattning : In many mining regions of the world, pollution of surface water and groundwater by drainage water originating from mines aiming waste poses either a serious threat to the environment, or a severe environmental problem. During the last two and a half decades, treatment of mine drainage water in constructed and natural wetlands has emerged as an alternative to more conventional methods to handle the problem. LÄS MER
