Determination of enzymatic activities for the characterization of sediments

摘要: In‐vivo enzymatic activity tests have been used for the characterization of sediments. Sediment samples representing three typical situations on river Elbe and one reference site Spree were investigated from March to October 1993. Fresh sediments pore water analyzed their dehydrogenase proteolytic activities, respectively. The protease activities varied depending sampling site, date kind sample. From mean values over whole period investigation significant differences between sites became evident. rather than that sediment is suitable differentiate anthropogenically influenced not sites. in contaminated extremly higher those uncontaminated samples. In contrast this, showed a considerably specific p...
