چکیده انگلیسی
In this contribution, we explore the potential of proton electron double resonance imaging (PEDRI) in environmental science (hydrogeological) applications. After a discussion of the hydrogeological motivation for studies of free radical transport in environmental matrices, we present results from first experiments that show the principal applicability of the PEDRI technique to sediment samples. Field-cycled (FC) relaxation time contrast is identified as a possible source of artifacts in samples in which strong concentration gradients of the free radical phase are present. Furthermore, an outlook is given on how PEDRI can help in observations of the local interplay among contaminants, water and nonaqueous liquid phases.
