Biophysical Chemistry of Fractal Structures and Processes in Environmental Systems. Disorder appears to predominate in natural and environmental systems, e.g. star constellations, clouds, coastlines, trees and snowflakes. In the natural environment, there is a great need to quantitatively describe complex physicochemical systems and processes. By their very nature, environmental systems are prefect candidates for quantitative description using fractal dimensions. Indeed, fractal geometry is a powerful approach of the quantitative description of complex, highly irregular and random systems, the processes that lead to the formation of such disordered systems and the physical behaviour that results from such apparent disorder. Biophysical Chemistry of Fractal Structures and Processes in Environmental Systems aims to provide the scientific community with a novel and valuable approach based on fractal geometry concepts. A number of important properties and processes are examined in diverse environmental systems. For example, this volume examines how the fractal approach has been applied to better understand the structure and reactivity of flocs, sediments, soils, microorganism, and humic substances. the book will be of great use to scientists and engineers looking for the fundamental knowledge necessary to solve practical environmental problems. Topics covered include: An introduction to the study of environmental fractalsFractal geometry, fragmentation processes and multifractal measuresMethods and techniques for the fractal analysis of environmental systemsFractal structures and mechanisms in coagulation/flocculation processes in environmental systemsFractal approaches to adsorption/desorption processes on environmental surfacesThe application of fractals in the study of humic materialsFractal geometry and microorganisms in the environmentFractal geometry of aerosol particlesThis comprehensive volume is aimed at graduate students, scientists, researchers and professionals involved in fundamental and applied studies in environmental sciences, with emphasis on environmental analytical chemistry, biochemistry and physical chemistry. The IUPAC Series on Analytical and Physical Chemistry of Environmental Systems provides the scientific community with a critical evaluation of important physicochemical structures and reactions in environmental systems, as well as the analytical techniques required to study them. The series is aimed at promoting rigorous analysis and understanding of the physicochemical functioning of environmental systems.

This text presents the current knowledge of environmental colloids and includes reviews of the current understanding of structure, role and behaviour of environmental colloids and particles, whilst focussing directly on aquatic systems and soils. In addition, there is substantial critical assessment of the techniques employed for the sampling, size fractionation and characterisation of colloids and particles. Chemical, physical and biological processes and interactions involving colloids are described, and particular attention is paid to quantitative approaches that take account of particle heterogeneity and polydispersity. Presents critical reviews of the state-of-the-art knowledge of environmental colloidsCritical assessment of techniques employed for the sampling, size fractionation and characterisation of colloids and particles are givenTheoretical and experimental aspects of the methods as well as the required developments and possible recommendations are discussedEach chapter gives a brief introduction general enough for the non-specialistWritten by a internationally recognized group of contributors
