effects of nitrates and their fate in the environment. Adopting an
integrated approach it covers the agricultural, environmental and
medical aspects of this emotive topic. In addition, there is an
extensive description of the biochemistry of nitrates in plants,
animals and humans including the positive aspects as well as the
hazards.
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.
As part of its efforts to improve fertilizer use and efficiency in
West Africa, and following the recent adoption of the West African

Bio-Geotechnologies for Mine Site Rehabilitation deals with the
biological, physical, chemical, and engineering approaches
necessary for the reclamation of mine waste. As mining has negative
effects on natural resources and deteriorates the quality of the
surrounding environment, this book provides coverage across
different types of mining industries, which are currently creating
industrial deserts overloaded with technogenic waste. The book
offers cost-effective strategies and approaches for contaminated
sites, along with remediation and rehabilitation methods for
contaminated soils and waste dumps. It is an essential resource for
students and academics, but is also ideal for applied professionals
in environmental geology, mineral geologists, biotechnologists and
policymakers.
The monograph introduces the reader to the world of inductive well
logging - an established method for surveying the electrical
conductivity of rocks surrounding a borehole. The emphasis is on
developing a theory of inductive logging and on understanding
logging tools basic physics, since this theory and understanding
furnish valuable insights for inventing practical induction logging
techniques.
The first chapter of the book presents the basic laws of
electromagnetism from a point of view that will facilitate the
application of the theory to problems in electromagnetic logging.
Many topics that play an important role in the design and
interpretation of tools readings are covered. The vertical
resolution and radial depth of investigation of different induction
tools is systematically considered. Special attention is paid to
principles of induction logging with transversal induction coils,
to transient method of induction logging in media with cylindrical
and horizontal interfaces and to the influence of anisotropy on the
electromagnetic field measured in a conducting medium. Multi-coil
differential induction probes and induction logging based on
measuring the inphase component of the secondary field or the
quadrature component difference are also described in detail. The
last chapter is devoted to mathematical modeling of the response of
induction logging tools in 3D geometries. The theory of inductive
logging presented in this volume can be applied to logging after
drilling as well as logging while drilling.
Written by the world's leading expert, this is an accessible introduction to optical dating for earth scientists who rely on the results given without needing to understand the technicalities of the technique.

scientific inputs into the policy consultation of the Forum
co-organized by the UNCRD/UNDESA, MoEFCC India, MOUD India and
MOEJ, Japan. 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: - Equilibrium models for environmental compartments
- Dry deposition of particles and vapors onto water and soil surfaces
- Chemical profiles in rivers and estuaries, particles and porous media
- Fate and transport in the atmospheric boundary layer and within subterranean media
- Chemical exchange between water column and bed-sediment
- Intraphase chemical transport and fate
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.
Key Features
* Addresses the role of water in the whole range of plant
activities
* Describes molecular mechanisms of water action in the context of
whole plants
* Synthesizes recent scientific findings
* Relates current concepts to agriculture and ecology
* Provides a summary of methods
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.
