SPP 1315: Visualization and quantification of processes at biogeochemical interfaces with magnetic resonance imaging
Description:
Objectives • Development of markers to access the spatial distribution of selected organic chemicals in soil • Visualization of biogeochemical interfaces in soil • Development of a technique to characterize the activity of biogeochemical interfaces in the spatial and temporal domain Hypotheses The fate of organic pollutants in soil is controlled by spatial features of the biogeochemical interfaces which may vary in the time domain. Most reactions at interfaces in soil are diffusion limited, that is, mass transfer rates to and from the interface are controlled by diffusion. Preferential flow might lead to a development of active interfaces along the flow path. During the development of active interfaces, flow paths might alter because of topological changes of the pore space caused by the development of interfaces and new preferential flow paths might evolve.
