Environmental isotopes in biodegradation and bioremediation

The use of stable and naturally occurring radioisotopes has gained increasinginterest as a way to assess microbial processes in surface and subsurface sediments. This book provides an understanding of this application, clearly defines these isotopes, and presents a detailed explanation of microbial processes in contaminated and uncontaminated environments. A wide range of case studies illustrate the concepts discussed in the text as well as the methodology used to conduct this application. The book also reviews recent research carried outin the field and in the laboratory from various disciplines currently employing this approach. INDICE: Section I: Isotope Fundamentals Fundamentals of Environmental Isotopes and Their Use in Biodegradation. Analysis of Stable Isotopes. Principlesand Mechanisms of Isotope Fractionation. Isotope Fractionation During Transformation Processes. Section II: Isotopes and Microbial Processes Isotopes and Aerobic Degradation. Isotopes and Methane Cycling. Isotopes and Processes in the Nitrogen and Sulfur Cycles. Section III: Isotopes in Field Applications Interpretation of Isotope Data at the Field Scale in the Unsaturated Zone. Stable Isotope Fractionation of Gases and Contaminant Vapors in the Unsaturated Zone.Section IV: Isotope Emerging Areas Isotopic Labeling in Environmental and Biodegradation Studies. Combined Use of Radiocarbon and Stable Carbon Isotopes inEnvironmental and Degradation Studies. Nontraditional Stable Isotopes in Environmental Sciences. Index
