This book pioneers a novel approach to investigate the effects of pressure on fission tracks, a geological problem that has remained unsolved for 60 years. While conventional techniques to study fission tracks were limited in precision, this book overcomes such issues by using state-of-the-art synchrotron-based x-ray scattering; a technique initially developed for applications in material science and biomedical research. The book provides an overview of the theory and application of small angle x-ray scattering (SAXS) on cylindrical ion tracks, including in-situ SAXS on ion tracks with simultaneous increases in temperature and pressure. As such it demonstrates a degree of characterisation normally not achievable with in-situ techniques. Further, it compares SAXS with small angle neutron scattering (SANS). This book has led to a range of publications and attracted the interest of the geological and material science communities. Daniel Schauries has been awarded several prizes for this research, including the Graduate Student Award of the Materials Research Society.

Presenting research on solid waste management from more than 30 countries, the book is divided into three volumes and addresses various issues related to innovation and implementation in sustainable waste management, segregation, collection, transportation of waste, treatment technology, policy and strategies, energy recovery, life cycle analysis, climate change, research and business opportunities.
What happens to a chemical once it enters the natural environment? How do its physical and chemical properties influence its transport, persistence, and partitioning in the biosphere? How do natural forces influence its distribution? How are the answers to these questions useful in making toxicological and epidemiological forecasts? Environmental Chemodynamics, Second Edition introduces readers to the concepts, tools, and techniques currently used to answer these and other critical questions about the fate and transport of chemicals in the natural environment. Like its critically acclaimed predecessor, its main focus is on the mechanisms and rates of movement of chemicals across the air/soil, soil/water, and water/air interfaces, and on how natural processes work to mobilize chemicals near and across interfaces—information vital to performing human and ecological risk assessments. Also consistent with the first edition, Environmental Chemodynamics, Second Edition is organized to accommodate readers of every level of experience. The first section is devoted to theoretical underpinnings and includes discussions of mass balance, thermodynamics, transport science concepts, and more. The second section concentrates on practical aspects, including the movement between bed-sediment and water, movement between soil and air, and intraphase chemical behavior. This revised and updated edition of Louis J. Thibodeaux's 1979 classic features new or expanded coverage of:
This Second Edition of Environmental Chemodynamics also includes twice as many references and 50% more exercises and practice problems.

This book presents a summary of terrestrial microbial processes, which are a key factor in supporting healthy life on our planet. The authors explain how microorganisms maintain the soil ecosystem through recycling carbon and nitrogen and then provide insights into how soil microbiology processes integrate into ecosystem science, helping to achieve successful bioremediation as well as safe and effective operation of landfills, and enabling the design of composting processes that reduce the amount of waste that is placed in landfills. The book also explores the effect of human land use, including restoration on soil microbial communities and the response of wetland microbial communities to anthropogenic pollutants. Lastly it discusses the role of fungi in causing damaging, and often lethal, infectious diseases in plants and animals.
Interdisciplinary Teaching about the Earth and Environment for a Sustainable Future presents the outcomes of the InTeGrate project, a community effort funded by the National Science Foundation to improve Earth literacy and build a workforce prepared to tackle environmental and resource issues. The InTeGrate community is built around the shared goal of supporting interdisciplinary learning about Earth across the undergraduate curriculum, focusing on the grand challenges facing society and the important role that the geosciences play in addressing these grand challenges. The chapters in this book explicitly illustrate the intimate relationship between geoscience and sustainability that is often opaque to students. The authors of these chapters are faculty members, administrators, program directors, and researchers from institutions across the country who have collectively envisioned, implemented, and evaluated effective change in their classrooms, programs, institutions, and beyond. This book provides guidance to anyone interested in implementing change-on scales ranging from a single course to an entire program-by infusing sustainability across the curriculum, broadening access to Earth and environmental sciences, and assessing the impacts of those changes.
This book examines two mid-nineteenth century thinkers - the Austrian writer Adalbert Stifter and the French architect Eugene E. Viollet-le-Duc - who imagined cultural history on the model of earth history: as a history of objects to be restored and worlds to be reconstructed. The nascent field of geology shaped cultural thought; their conservationism, informed by erosion, envisions a future of restorative renewal.
Bioremediation is the use of microorganisms' metabolism to degrade waste contaminants (sewage, domestic, and industrial effluents) into non-toxic or less toxic materials by natural biological processes. Volume 2 offers new discussion of remediation through fungi-or mycoremediation-and its multifarious possibilities in applied remediation engineering and the future of environmental sustainability. Fungi have the biochemical and ecological capability to degrade environmental organic chemicals and to decrease the risk associated with metals, semi-metals, noble metals, and radionuclides, either by chemical modification or by manipulating chemical bioavailability. Additional expanded texts shows the capability of these fungi to form extended mycelia networks, the low specificity of their catabolic enzymes, and their use against pollutants as a growth substrate, making these fungi well suited for bioremediation processes. Their mycelia exhibit the robustness of adapting to highly limiting environmental conditions often experienced in the presence of persistent pollutants, which makes them more useful compared to other microbes. Despite dominating the living biomass in soil and being abundant in aquatic ecosystems, however, fungi have not been exploited for the bioremediation of such environments until this added Volume 2. This book covers the various types of fungi and associated fungal processes used to clean up waste and wastewaters in contaminated environments and discusses future potential applications.
Water Relations of Plants and Soils, successor to the seminal 1983
book by Paul Kramer, covers the entire field of water relations
using current concepts and consistent terminology. Emphasis is on
the interdependence of processes, including rate of water
absorption, rate of transpiration, resistance to water flow into
roots, soil factors affecting water availability. New trends in the
field, such as the consideration of roots (rather than leaves) as
the primary sensors of water stress, are examined in detail.
Meeting the food requirements of an ever-increasing population is a pressing challenge for every country around the globe. Soil degradation has a negative impact on food security by reducing the cultivated land areas, while at the same time the world population is predicted to increase to 9.2 billion in 2050. Soil degradation adversely affects soil function and productivity and degraded soils now amount to 6 billion ha worldwide. The major factors are salinization, erosion, depletion of nutrients due to exhaustive agricultural practices and contamination with toxic metal ions and agrochemicals, which reduces the activity of soil microbe. In addition, poor soil management also decreases fertility. As such, measures are required to restore the soil health and productivity: organic matter, beneficial microorganisms and nutrient dynamics can all improve the physical, chemical and biological properties of soil. Understanding the role of soil health restoration and management in sustainability and nutritional security calls for a holistic approach to assess soil functions and examine the contributions of a particular management system within a defined timescale. Further, best management practices in cropping systems are important in ensuring sustainability and food and nutritional security without compromising the soil quality and productivity po tential. Rational soil management practices must allow environmentally and economically sustain able yields and restoration of soil health. |
