Opis

The use of stable and naturally occurring radioisotopes has gained increasing interest 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 out in the field and in the laboratory from various disciplines currently employing this approach.
