Soil and Environmental Analysis: Modern Instrumental TechniquesKeith A. Smith, Malcolm S. Cresser Evaluating traditional and recent analytical methods according to speed, sensitivity, and cost-efficiency, this reference supports specialists in the selection of effective analytical techniques and equipment for the study of soils, soil contaminants, and environmental samples. Updated and revised, this Third Edition illustrates the advantages, limitations, range, and challenges of the major analytical approaches utilized in modern research laboratories. It includes new chapters and expanded discussions of the measurement of organic pollutants in the environment and gas fluxes between the land surface and atmosphere, and an extensive range of environmental materials. |
