Microsensors were used in order to perform profiles of redox potential and pH within biofilms, which have formed in small drainage channels of uranium contaminated acidic mine drainage (AMD) waters from an underground uranium mine in Saxony (Germany)

Molecular speciation is a prerequisite for reliable assessment of contaminant migration in the environment. We use sophisticated techniques for concentrating colloids (e.g. ultracentrifugation, ultrafiltration) in combination with Extended X-ray Abso

Abandoned uranium mines which underwent or just undergo flooding may represent a severe source of radioactive contaminants against groundwater, surface water, and the atmosphere. The uranium mines operated until 1990 in Saxony and Thuringia left a to
