DETERMINATION OF INORGANIC SPECIES IN SEEPAGE WATER OF URANIUM-MININGROCKPILES AND IN RELATED MEDIA

Investigations are currently carried out in Saxony to study environmen tal impacts due to uranium-mining activities. Radioactive and other in organic species were determined in both mining waters of different ori gin and leachates from mediumscale column experiments and batch-tests. Uranium concentrations were measured using gamma-spectrometry, absorp tion spectrophotometry, square-wave polarography and inductively coupl ed mass spectrometry. For mining waters the concentration range was le ss than 1 to ca 4 mg . dm-3, in one case up to 7 mg . dm-3.
