Nuclear magnetic resonance studies of interactions between organic pollutants and soil components,a review

This article presents a short overview of selected recent papers using nuclear magnetic resonance (NMR) to investigate interactions between organic pollutants and soil components such as organic matter, clays, whole soils, and sediments. First, we describe solid state cross polarisation magic angle spinning (CP-MAS) experiments as the main tools to investigate covalent bonds. Second, we report NMR approaches allowing us to assess molecule mobility and to characterise non-covalent interactions. Those approaches include correlations between K _oc values and soil organic matter functions determined by CP-MAS, ²H NMR fingerprints, relaxation time measurements, ¹⁹F and ¹H high resolution (HR)-MAS experiments.
