During the last four decades, tremendous advances have been made towards the understanding of transport characteristics of contaminants in soils, solutes, and tracers in geological media. Transport & Fate of Chemicals in Soils: Principles & Applications offers a comprehensive treatment of the subject complete with supporting examples of mathematical models that describe contaminants reactivity and transport in soils and aquifers. This approach makes it a practical guide for designing experiments and collecting data that focus on characterizing retention as well as release kinetic reactions in soils and contaminant transport experiments in the laboratory, greenhouse), and in the field. The book provides the basic framework of the principals governing the sorption and transport of chemicalsin soils. It focuses on physical processes such as fractured media, multiregion, multiple porosities, and heterogeneity and effect of scale as well as chemical processes such as nonlinear kinetics, release and desorption hysteresis, multisite and multireaction reactions, and competitive-type reactions. The coverage also includes details of sorption behavior of chemicals with soil matrix surfaces as well the integration of sorption characteristics with mechanisms that govern solute transport in soils. The discussions of applications of the principles of sorption and transport are not restricted to contaminants, but also include nitrogen, phosphorus, and trace elements including essential micronutrients, heavy metals, military explosives, pesticides, and radionuclides. Written in a very clear and easy-to-follow language by a pioneer in soil science, this book details the basic framework of the physical and chemical processes governing the transport of contaminants, trace elements, and heavy metals in soils. Highly practical, it includes laboratory methods, examples, and empirical formulations. The approach taken by the author gives you not only the fundamentals of understanding of reactive chemicals retention and their transport in soils and aquifers, but practical guidance you can put to immediate use in designing experiments and collecting data.
Hypoxia is a constant threat throughout life. International experts from many different fields, including clinicians, clinical researchers, and basic scientists, have contributed to this volume, presenting state-of-the-art information regarding normal and abnormal (pathophysiological) responses to hypoxia. The topics covered include visitors to high altitude, the latest developments on high-altitude cerebral and pulmonary edema, the brain in hypoxia, high-altitude headache, and similarities between ischemic and hypoxic injury to the brain. In addition topics are covered such as blood-brain barrier in hypoxia, hypoxia interactions with vascular growth, and how humans adjust to extreme hypoxia.
This edited volume provides a biosemiotic analysis of the ecological relationship between food and medicine. Drawing on the origins of semiotics in medicine, this collection proposes innovative ways of considering aliments and treatments. Considering the ever-evolving character of our understanding of meaning-making in biology, and considering the keen popular interest in issues relating to food and medicines - fueled by an increasing body of interdisciplinary knowledge - the contributions here provide diverse insights and arguments into the larger ecology of organisms' engagement with and transformation through taking in matter. Bodies interpret molecules, enzymes, and alkaloids they intentionally and unintentionally come in contact with according to their pre-existing receptors. But their receptors are also changed by the experience. Once the body has identified a particular substance, it responds by initiating semiotic sequences and negotiations that fulfill vital functions for the organism at macro-, meso-, and micro-scales. Human abilities to distill and extract the living world into highly refined foods and medicines, however, have created substances far more potent than their counterparts in our historical evolution. Many of these substances also lack certain accompanying proteins, enzymes, and alkaloids that otherwise aid digestion or protect against side-effects in active extracted chemicals. Human biology has yet to catch up with human inventions such as supernormal foods and medicines that may flood receptors, overwhelming the body's normal satiation mechanisms. This volume discusses how biosemioticians can come to terms with these networks of meaning, providing a valuable and provocative compendium for semioticians, medical researchers and practitioners, sociologists, cultural theorists, bioethicists and scholars investigating the interdisciplinary questions stemming from food and medicine.
Ecology is cross-disciplinary field involving many different aspects of science. Written with this in mind, this book introduces ecological processes, ranging from physical processes, to chemical processes and biological processes.

Even a cursory perusal of any analytical journal will demonstrate the increasing important of trace and ultra-trace analysis. And as instrumentation continues to develop, the definition of the term "trace element" will undoubtedly continue to change. Covering the composition and underlying properties of freshwater and marine systems, Analytical Measurements in Aquatic Environments provides the basis for understanding both. It discusses all aspects of analytical protocols from the handling of representative samples to the metrological evaluation of specific steps and whole procedures. The book covers: handling of representative samples sample preservation techniques extraction techniques speciation analytics solvent-free sample preparation for analysis application of biotests bioanalytical methods for monitoring green analytical chemistry-application of the concept of sustainability in analytical laboratories application of the Life Cycle Assessment approach quality control and quality assurance of analytical results enhanced techniques of sample preparation hyphenated analytical techniques Ecotoxicological considerations and the effort to achieve an increasingly accurate description of the state of the environment challenge analytical chemists who need to determine increasingly lower concentrations of various analytes in samples that have complex and even non-homogenous matrices. The newly coined expression "analytics" emphasizes the interdisciplinary nature of available methods for obtaining information about material systems, with many methods that exceed the strict definition of analytical chemistry. Drawing on the disciplines of chemistry, physics, computer science, electronics, material science, and chemometrics, this book provides in depth information on the most important problems in analytics of samples from aquatic ecosystems.
Most reported incidents of soil contamination include an array of heavy metals species rather than a single ion. The various interactions in these multicomponent or multiple-ion systems significantly impact the fate and transport of heavy metals, and competition for sorption sites on soil matrix surfaces is a common phenomenon. Because of this, considering competitive sorption is an important part of predicting contaminant transport. Competitive Sorption and Transport of Heavy Metals in Soils and Geological Media gives you the information needed to understand heavy metals' sorption and transport in the vadose zone and aquifers. The book brings together state-of-the art research on the competitive sorption and mobility of single versus multiple heavy metal species. It also relates the transport mechanisms to the processes that govern sorption mechanisms. The work offers new experimental evidence on the fate of multiple heavy metals in soil columns and new field results on how multiple ions influence the mobility of metals in the soil profile under water-unsaturated flow. Emphasizing modeling approaches, the book begins with an overview of the competitive behavior of heavy metals. It then takes a closer look at various heavy metals, discussing their behavior in tropical soils, speciation and fractionation, accumulation, migration, competitive retention, and the contamination of water resources at the watershed scale. The book also presents extensive data on phosphate, a commonly used fertilizer, and its role in facilitating the release of trace elements. The final chapter looks at the effect of waterlogged conditions on arsenic and cadmium solubilization. Edited by an internationally recognized researcher and featuring expert contributors, this comprehensive work addresses the complex physical and chemical phenomena of sorption mechanisms. Presenting the latest research, it helps you to better predict the potential mobility of multiple heavy metals in soils.

Also in this part, the perturbation of natural cycles by agricultural, industrial, and social developments is highlighted in terms of the consequent problems of environmental management.
Environmental Fate and Transport Analysis with Compartment Modeling explains how to use the powerful, highly flexible, and intuitive compartment approach to estimate the distribution of chemical contaminants in environmental media in time and space. Add this Easy-to-Use Approach to Your Environmental Modeling Toolbox This numerical technique enables readers to easily develop the equations that describe complex environmental problems by assembling the equations out of compartmental building blocks. The compartments may describe spatial subunits of single- or multi-environmental media, and the way one hooks them together implicitly provides the dimensionality of the problem. With this approach, assembling the equations to describe chemical fate and transport in a three-dimensional, multimedia system is fundamentally no more challenging than a one-dimensional, single-medium problem. Go Beyond "Black Box" Modeling with the Flexible GEM Software The book includes access to the Generic Environmental Model (GEM), a new software package developed by the author. This software implements the compartment approach based on user-prepared input files and solves the resulting mathematical equations. It allows readers to solve linear, nonlinear, and steady-state problems and offers four methods for solving dynamic problems. Each solution technique is reviewed, along with the error properties and the criteria for avoiding or minimizing numerical errors. The book also describes solution techniques and the underlying mathematical theory for solving nonlinear systems. Compartment Modeling from the Ground Up, Made Accessible to Non-Mathematicians A user-friendly introduction to environmental compartment modeling for the beginning modeler, this is also a useful resource for the experienced modeler. It combines a reference on compartment modeling with a user's guide to the GEM. Throughout, the GEM is used to illustrate the theory with numerous examples, while the theoretical discussions illuminate the GEM's functionality.
This open access book deals with global sanitation, where SDG 6.2 sets a target of enabling access to sanitation services for all, but has not yet been achieved in low- and middle-income countries. The transition from the United Nations MDGs to the SDGs requires more consideration based on the socio-cultural aspects of global sanitation. In other words, equitable sanitation for those in vulnerable situations could be based on socio-cultural contexts. Sanitation is a system that comprises not only a latrine but also the works for the treatment and disposal of human waste. Sanitation systems do not function by themselves but have significance only through social management. The process of decision-making also largely depends on socio-cultural conditions, and the importance of sanitation needs to be socially acknowledged. The health benefits of sanitation improvement-among the significant contributions of sanitation-also need to be considered in the socio-cultural milieu. Further, the social-culture itself is affected, and potentially even created, by sanitation. In this context, more progress on the improvement of sanitation requires a more holistic approach across disciplines. In this book, we present the concept of the Sanitation Triangle, which considers the interconnections of health, materials, and socio-culture in sanitation, as a holistic approach, and the case studies based on the Sanitation Triangle by diverse disciplines such as Cultural Anthropology, Development Studies, Health Sciences, Engineering, and Science Communication. By the deep theoretical examinations and inter-dialogues between the different disciplines, this book explores the potentialities of inter-disciplinary studies on global sanitation.
