Book Description
Clearly explains how to more effectively decipher and predict contaminant fate in the environment by combining kinetic methods and molecular-scale spectroscopic and microscopic techniques to analyze mineral/water interfacial reactions in situ. The book begins with a broad overview, then continues with three sections written by internationally known expert. The first deals specifically with spectroscopic/microscopic techniques that can be used in combination with macroscopic approaches to glean mechanistic information on mineral/water reactions and processes. The second section emphasizes computer models that are used to elucidate surface mediated reaction mechanisms. The remainder of the volume is organized around reaction type, including sorption/desorption of inorganic species, sorption/desorption of organic species, precipitation/dissolution processes, heterogeneous electron transfer reactions, photochemically driven reactions, and microbially mediated reactions. Mineral-Water Interfacial Reactions will be a valuable resource for environmental scientists, geochemists, soil chemists, microbiologists, and marine engineers who need to be familiar with the most current and effective methods for testing and controlling the mobility, speciation, and bioavailability of contaminants in the environment.

Book Description
Based on the “International Symposium of Molecular Environmental Soil Science at the Interfaces in the Earth’s Critical Zone,” this book focuses on the Critical Zone supporting life at the Earth’s surface with emphasis on the new and emerging subject area of molecular environmental soil science. Advances in research methodology, the use of synchrotron radiation in particular, are extensively reviewed. Roles of microbes, biomolecules, and environmental nanoparticles in mineral transformations, metal cycling, degradation of natural and anthropogenic organic compounds are also extensively reviewed. It is unique in terms of facilitating the integration of contributions from traditionally separate disciplines and adding a molecular and nanoparticle (therefore chemical) dimension to a field of endeavour that has traditionally been viewed on a different scale (dimension). It will also contribute to identifying knowledge gaps, providing future research directions and promoting research and education at the molecular level in this extremely important and challenging area of science for years to come. The IUPAC Project Committee noted that the Conference identifies, and builds on, the need to view and understand the Critical Zone at the molecular level. The book will be an invaluable reference for research and education.

Book Description
Microbial Biodegradation of Xenobiotic Compounds examines and collects the recent information on the bioremediation technologies around the world. This book focuses on methods to decrease pollutants created by anthropogenic activities, industrial activities, and agricultural activities. This book answers some of the questions about – how to reduce contaminants? And whether there is a possibility of converting these pollutants in to useful energy by advanced biotechnological methods? The book combines present obtainable data with the expert knowledge of researchers from all over the world covering different aspects of environmental biotechnology and microbiology. It covers basic concepts of bioremediation and various methods involved in the bioremediation process, and provides specific chapters on the role of different genes and enzymes involved in microbial bioremediation process. It also gives special attention to heavy metal bioremediation by microalgae and the mechanisms involved during the degradation process. Recent innovative technologies about converting toxic pollutants in to useful energy like bioplastics and electricity are also discussed by specialist authors. Various chapters address the bioremediation of pesticides in soil using microbial metabolites, and molecular aspects of biodegradation which cover topics including identification of novel genes through the metagenomic approach and bioremediation using fungal laccase enzymes.

Book Description
Molecular processes in nature affect human health, the availability of resources and the Earth’s climate. Molecular modelling is a powerful and versatile toolbox that complements experimental data and provides insights where direct observation is not currently possible. Molecular Modeling of Geochemical Reactions: An Introduction applies computational chemistry to geochemical problems. Chapters focus on geochemical applications in aqueous, petroleum, organic, environmental, bio- and isotope geochemistry, covering the fundamental theory, practical guidance on applying techniques, and extensive literature reviews in numerous geochemical sub-disciplines. Topics covered include: • Theory and Methods of Computational Chemistry • Force Field Application and Development • Computational Spectroscopy • Thermodynamics • Structure Determination • Geochemical Kinetics This book will be of interest to graduate students and researchers looking to understand geochemical processes on a molecular level. Novice practitioners of molecular modelling, experienced computational chemists, and experimentalists seeking to understand this field will all find information and knowledge of use in their research.

Book Description
Given the presence of a wide variety of contaminants in the environment, it is important to understand what drives a contaminant from one medium to another, as well as the manner and extent to which a contaminant associates with the different media or phases within a local environmental system. Partition and Adsorption of Organic Contaminants in Environmental Systems forms a comprehensive resource on the behavioral characteristics of contaminants so that appropriate strategies can be adopted to either prevent or minimize their adverse impacts on human welfare and natural resources. Cary Chiou’s far-reaching text depicts the processes by which nonionic organic contaminants are sorbed to natural biotic and abiotic substances. This book focuses on physical principles and system parameters that affect the contaminant uptake by soil from water, air, and other media; by fish from water; and by plants from soil and water. As contaminant uptake by natural organic substances is often predominantly a partition interaction, the partition characteristics in several solvent-water model mixtures are treated in detail to elucidate the relevant physicochemical parameters. The account of contaminant sorption to soils, fish, and plants is strengthened by companion chapters on: Fundamentals of solution theory Interphase partition equations Fundamentals of adsorption theory Vapor adsorption on mineral and carbonaceous solids No other single source in the field delivers as compelling a combination of background understanding and "state-of-the-science" comprehension of current issues. Ideally suited for a graduate-level environmental course, Partition and Adsorption of Organic Contaminants in Environmental Systems also serves as a technical guide to current and future research in the field.
