NMR spectroscopy has been used to study environmental samples since the early 1960s.  One of the first applications, by Barton and Schnitzer in 1963 (Nature 198:217-218), used solution-state 1H NMR to study the composition of isolated soil humic substances.  Since this time, the advancements in NMR have resulted in a wide range of methods to be applied to environmental samples and required the development of environment-specific methods, such as comprehensive multi-phase NMR.  This handbook is organized into three parts: Part 1 focuses on methods used in environmental NMR which span from solution-state to magnetic resonance imaging.  Part 2 emphasizes how NMR spectroscopy has played an essential role in understanding various types of environmental components and related processes.  These include different forms of organic matter found in soil, water, and air as well as how NMR is used to probe the fate of water, organic pollutants, and metals in the environment.  Part 3 focuses on the growing field of environmental metabolomics which uses NMR as its main discovery platform.  NMR-based environmental metabolomics is reshaping the understanding of ecotoxicity of problematic environmental pollutants in different environments. All these chapters will also be published in eMagRes.
