The subproject HUMUS aimed to characterize the interaction between water and organic matter and to derive their effects on the sorption of hydrophobic organic pollutants

In this first phase the subproject HUMUS examined the binding of water in soil organic matter by thermoanalytic methods (in particular DSC). In addition, 1H NMR relaxation (subproject GEO) as well as kinetic studies of the release and swelling of soil organic matter were performed.

In this first phase the subproject HUMUS examined the binding of water in soil organic matter by thermoanalytic methods (in particular DSC). In addition, 1H NMR relaxation (subproject GEO) as well as kinetic studies of the release and swelling of soil organic matter were performed. Field experiments and microcosmic investigations of the research group were carried out in order to analyze the connection between the water binding in soil organic matter and other soil properties. The first phase has shown that besides the macromolecular properties of the organic matter, biofilms and the water repellency also represent important characteristics of a habitat.
