摘要: A total of 35 groundwaters from 4 different aquifer systems in Germany are investigated for their physico-chemical properties, dissolved organic C (DOC) and humic fulvic acids. Humic substances isolated characterized elemental composition, UV/Vis fluorescence spectroscopic size distribution by gel permeation chromatography (GPC) 14C content. For isolation sufficient quantities a mobile sampling system is developed based on combination reverse osmosis (RO) XAD–8 adsorption chromatography. One the (Gorleben) covers wide range hydrogeochemical conditions, whereas other 3 (Munich, Franconian Albvorland Fuhrberg) have less diverse properties. specific feature Gorleben presence very high DOC, which, contrast to systems, contains considerable amounts aquatic acid. This attributed release originating sedimentary (SOC) that abundant sediments. The results show dissimilar properties which differ one another. Systematic differences found among regions system. Such considered be caused mixing SOC. However, exact quantification such appears difficult because overlapping effects geochemical processes feigning dissolution SOC cannot excluded.
