Abstract

This chapter presents the application of electron paramagnetic resonance (EPR) to soils, soil systems, and natural organic matter. The basic principles of EPR are introduced with a focus on the examples discussed within the chapter. The power and promise of EPR is illustrated using present-day applications (i) of high frequency EPR in environmental soil sciences, such as natural organic matter characterization and its binding of metals, (ii) of spin labels to probe pollutant sorption, and (iii) in the detection and characterization of a new class of compounds of interest known as environmentally persistent free radicals.
