Monitoring Environmental Contaminants (Hardcover): Steven Johnson Monitoring Environmental Contaminants (Hardcover)
Steven Johnson
R4,248 Discovery Miles 42 480 Ships in 10 - 15 working days

While existing approaches to monitoring environmental contaminants tend to focus on a small suite of contaminant types and often involve monitoring at fixed points and at fixed times, Monitoring Environmental Contaminants focuses on a wide range of new technologies and approaches available for monitoring chemical and biological contaminants in air, water, soil and food. These new methods allow the ability to monitor a wider range of contaminants at much greater and temporal resolutions. Adoption of these methods could result in a change in our understanding of how humans and ecosystems are exposed to contaminants in different environmental media. This volume in the Environmental Contaminants Series provides an overview of a wide range of monitoring approaches ranging from citizen science networks to the use of robotics and sensor networks. Monitoring Environmental Contaminants describes challenges in the adoption of some of these new approaches and methods for dealing with these challenges such as the use of mining techniques for large data. The case studies within will provide a thorough illustration for researchers, academics, and scientists involved in ecology and environmental sciences.

Urban Expansion, Land Cover and Soil Ecosystem Services (Paperback): Ciro Gardi Urban Expansion, Land Cover and Soil Ecosystem Services (Paperback)
Ciro Gardi
R1,452 Discovery Miles 14 520 Ships in 12 - 17 working days

More than half of the world population now lives in cities, and urban expansion continues as rural people move to cities. This results in the loss of land for other purposes, particularly soil for agriculture and drainage. This book presents a review of current knowledge of the extension and projected expansion of urban areas at a global scale. Focusing on the impact of the process of 'land take' on soil resources and the ecosystem services that they provide, it describes approaches and methodologies for detecting and measuring urban areas, based mainly on remote sensing, together with a review of models and projected data on urban expansion. The most innovative aspect includes an analysis of the drivers and especially the impacts of soil sealing and land take on ecosystem services, including agriculture and food security, biodiversity, hydrology, climate and landscape. Case studies of cities from Europe, China and Latin America are included. The aim is not only to present and analyse this important environmental challenge, but also to propose and discuss solutions for the limitation, mitigation and compensation of this process.

David Kay, C. Fricker
R3,405 Discovery Miles 34 050 Ships in 12 - 17 working days

This book is the proceedings of the conference Faecal Indicators: problem or solution? Has technical progress reduced the need for faecal indicators? held on 6th to 8th June 2011 at Edinburgh Conference Centre, Heriot Watt University, UK. It addresses existing and emerging issues in environmental microbiology which in turn offer exciting new challenges in microbiology, public health and environmental science. The ultimate aim being to assist the monitoring and modelling of environmental systems to protect human health, animal welfare and environmental quality. With contributions from leading scientists and experts in academia and industry, it offers a truly international perspective on both current research and our ability to respond with useful and sustainable solutions to many of the emerging challenges of today's modern communities. The conference featured two combative, provocative and engaging debates examining the moral issues behind the statements "What is a coliform and are coliforms relevant to public health?" and "Do regulations help or hinder the innovation in testing methods?." The reports of these questions are captured in the book. The book appeals across the board from those working in universities and research institutes to local governments, the water and food industries, and health professionals.

Statistical Methods for Trend Detection and Analysis - In the Environmental Sciences (Hardcover): RE Chandler Statistical Methods for Trend Detection and Analysis - In the Environmental Sciences (Hardcover)
RE Chandler
R2,524 Discovery Miles 25 240 Ships in 12 - 17 working days

The need to understand and quantify change is fundamental throughout the environmental sciences. This might involve describing past variation, understanding the mechanisms underlying observed changes, making projections of possible future change, or monitoring the effect of intervening in some environmental system. This book provides an overview of modern statistical techniques that may be relevant in problems of this nature. Practitioners studying environmental change will be familiar with many classical statistical procedures for the detection and estimation of trends. However, the ever increasing capacity to collect and process vast amounts of environmental information has led to growing awareness that such procedures are limited in the insights that they can deliver. At the same time, significant developments in statistical methodology have often been widely dispersed in the statistical literature and have therefore received limited exposure in the environmental science community. This book aims to provide a thorough but accessible review of these developments. It is split into two parts: the first provides an introduction to this area and the second part presents a collection of case studies illustrating the practical application of modern statistical approaches to the analysis of trends in real studies. Key Features: * Presents a thorough introduction to the practical application and methodology of trend analysis in environmental science. * Explores non-parametric estimation and testing as well as parametric techniques. * Methods are illustrated using case studies from a variety of environmental application areas. * Looks at trends in all aspects of a process including mean, percentiles and extremes. * Supported by an accompanying website featuring datasets and R code. The book is designed to be accessible to readers with some basic statistical training, but also contains sufficient detail to serve as a reference for practising statisticians. It will therefore be of use to postgraduate students and researchers both in the environmental sciences and in statistics.

Matthias Heymann, Gabriele Gramelsberger, Martin Mahony
R4,309 Discovery Miles 43 090 Ships in 12 - 17 working days

In recent decades, science has experienced a revolutionary shift. The development and extensive application of computer modelling and simulation has transformed the knowledge-making practices of scientific fields as diverse as astro-physics, genetics, robotics and demography. This epistemic transformation has brought with it a simultaneous heightening of political relevance and a renewal of international policy agendas, raising crucial questions about the nature and application of simulation knowledges throughout public policy. Through a diverse range of case studies, spanning over a century of theoretical and practical developments in the atmospheric and environmental sciences, this book argues that computer modelling and simulation have substantially changed scientific and cultural practices and shaped the emergence of novel 'cultures of prediction'. Making an innovative, interdisciplinary contribution to understanding the impact of computer modelling on research practice, institutional configurations and broader cultures, this volume will be essential reading for anyone interested in the past, present and future of climate change and the environmental sciences.

Handbook of Climate Services (Hardcover, 1st ed. 2020): Walter Leal Filho, Daniela Jacob Handbook of Climate Services (Hardcover, 1st ed. 2020)
Walter Leal Filho, Daniela Jacob
R4,763 Discovery Miles 47 630 Ships in 12 - 17 working days

This book explores climate services, including projections, descriptive information, analyses, assessments, and an overview of current trends. Due to the pressures now being put on the world's climate, it is vital to gather and share reliable climate observation and projection data, which may be tailored for use by different groups. In other words, it is essential to offer climate services. But despite the growth in the use of these services, there are very few specialist publications on this topic. This book addresses that need. Apart from presenting studies and the results of research projects, the book also offers an overview of the wide range of means available for providing and using climate services. In addition, it features case studies that provide illustrative and inspiring examples of how climate services can be optimally deployed.

This first comprehensive review of airborne measurement principles covers all atmospheric components and surface parameters. It describes the common techniques to characterize aerosol particles and cloud/precipitation elements, while also explaining radiation quantities and pertinent hyperspectral and active remote sensing measurement techniques along the way. As a result, the major principles of operation are introduced and exemplified using specific instruments, treating both classic and emerging measurement techniques.
The two editors head an international community of eminent scientists, all of them accepted and experienced specialists in their field, who help readers to understand specific problems related to airborne research, such as immanent uncertainties and limitations. They also provide guidance on the suitability of instruments to measure certain parameters and to select the correct type of device.
While primarily intended for climate, geophysical and atmospheric researchers, its relevance to solar system objects makes this work equally appealing to astronomers studying atmospheres of solar system bodies with telescopes and space probes.

Royal Society of Chemistry
R5,590 Discovery Miles 55 900 Ships in 12 - 17 working days

This volume focuses on the synthesis of emerging knowledge of the atmospheric aerosol systems, assessment of the validity and usefulness of existing frameworks, and the development of robust aerosol system descriptions on scales ranging from the interpretation of laboratory data to assessment of global impacts. Suspended particulate material in the atmosphere gives rise to a number of poorly determined problems of major current concern. Direct and indirect radiative forcing (the ability of aerosol particles to affect the Earth's radiation budget) each carries larger uncertainties than all other agents of climate change. Furthermore, there are significant challenges associated with the uncertainties of the impacts of particulate material on air quality and human health. A significant contributor to these uncertainties is the vast heterogeneity in the distribution of aerosols by virtue of their disparate sources (both primary and secondary) and transformations in the moist oxidising atmosphere. The complexity of aerosol precursors and variability in the oxidising environment leads to a highly variable loading of particles of widely ranging size, age and property. The topics covered in this volume include: * Formation, * Transformation, * Fate, and * Impacts of tropospheric aerosols.

GNSS Environmental Sensing - Revolutionizing Environmental Monitoring (Hardcover, 2nd ed. 2018): Joseph Awange GNSS Environmental Sensing - Revolutionizing Environmental Monitoring (Hardcover, 2nd ed. 2018)
Joseph Awange
R5,642 Discovery Miles 56 420 Ships in 12 - 17 working days

This book is the second edition of Environmental Monitoring using GNSS and highlights the latest developments in global navigation satellite systems (GNSS). It features a completely new title and additional chapters that present emerging challenges to environmental monitoring-"climate variability/change and food insecurity." Since the publication of the first edition, much has changed in both the development and applications of GNSS, a satellite microwave remote sensing technique. It is the first tool to span all four dimensions of relevance to humans (position, navigation, timing and the environment), and it has widely been used for positioning (both by military and civilians), navigation and timing. Its increasing use is leading to a new era of remote sensing that is now revolutionizing the art of monitoring our environment in ways never imagined before. On the one hand, nearly all GNSS satellites (Global Positioning System (GPS), Global Navigation Satellite System (GLONASS), Galileo and Beidou) have become operational, thereby providing high-precision, continuous, all-weather and near real- time remote sensing multi-signals beneficial to environmental monitoring. On the other hand, the emerging challenges of precisely monitoring climate change and the demand for the production of sufficient food for ever-increasing populations are pushing traditional monitoring methods to their limits. In this regard, refracted GNSS signals (i.e., occulted GNSS signals or GNSS meteorology) are now emerging as sensors of climate variability, while the reflected signals (GNSS reflectometry or GNSS-R) are increasingly finding applications in determining, e.g., soil moisture content, ice and snow thickness, ocean heights, and wind speed and direction, among others. Furthermore, the increasing recognition and application of GNSS-supported unmanned aircraft vehicles (UAV)/drones in agriculture (e.g., through the determination of water holding capacity of soil) highlights the new challenges facing GNSS. As such, this new edition three new chapters address GNSS reflectometry and applications; GNSS sensing of climate variability; and the applications in UAV/drones. Moreover, it explores the application of GNSS to support integrated coastal zone management.

Giampaolo Zuccheri, Nikolaos Asproulis
R3,352 Discovery Miles 33 520 Ships in 12 - 17 working days

Detection of Pathogens in Water Using Micro and Nano-Technology aims to promote the uptake of innovative micro and nano-technological approaches towards the development of an integrated, cost-effective nano-biological sensor useful for security and environmental assays. The book describes the concerted efforts of a large European research project and the achievements of additional leading research groups. The reported knowledge and expertise should support in the innovation and integration of often separated unitary processes. Sampling, cell lysis and DNA/RNA extraction, DNA hybridisation detection micro- and nanosensors, microfluidics, together also with computational modelling and risk assessment can be integrated in the framework of the current and evolving European regulations and needs. The development and uptake of molecular methods is revolutionizing the field of waterborne pathogens detection, commonly performed with time-consuming cultural methods. The molecular detection methods are enabling the development of integrated instruments based on biosensor that will ultimately automate the full pathway of the microbiological analysis of water. Editors: Giampaolo Zuccheri, University of Bologna, Italy and Nikolaos Asproulis, Cranfield University, UK

Field Sampling for Environmental Science and Management (Hardcover): Richard Webster, Murray Lark Field Sampling for Environmental Science and Management (Hardcover)
Richard Webster, Murray Lark
R4,309 Discovery Miles 43 090 Ships in 12 - 17 working days

Scientists and consultants need to estimate and map properties of the terrestrial environment. These include plant nutrients and parasites in soil, gaseous emissions from soil, pollutant metals and xenobiotics in waste and contaminated land, salt in groundwater and species abundances above ground. The scale varies from small experimental plots to catchments, and the land may be enclosed in fields or be open grassland, forest or desert. Those who sample the variables to obtain the necessary data need guidance on the design and analysis of sampling methods for their conclusions and recommendations to be valid.

This book provides that guidance, backed by sound rationale and statistical theory. It concentrates on design-based sampling for estimates of mean values of environmental properties, emphasizing replication and randomization. It starts with simple random sampling and then progresses to more efficient designs, such as spatially stratified random sampling, stratification by classes and cluster sampling. It includes a section on purposive sampling in classical soil survey, which is relevant to other environmental properties such as vegetation. It also describes the effects of bulking on errors and the use of ancillary information and regression to improve estimates. The authors draw the important distinction between design-based sampling for estimating means and model-based methods (geostatistics) for local spatial prediction and mapping, and focus on the latter. They describe designs suitable for computing variograms and prediction by kriging, as well as a staged approach, so that sampling is neither inadequate nor excessive, and designs adapt as knowledge is accumulated. Including numerous worked case studies of sampling in agriculture, ecology and environmental science, the book will be of immediate practical value.

Behaviors of Trace Metals in Environment - The Pollution in Regional and Metropolis Areas (Hardcover, 1st ed. 2020): Hui Zhang Behaviors of Trace Metals in Environment - The Pollution in Regional and Metropolis Areas (Hardcover, 1st ed. 2020)
Hui Zhang
R2,927 Discovery Miles 29 270 Ships in 10 - 15 working days

This book focuses on the behavior and impact of trace metals in the environment by studying typical cases from China such as the Hetao Area of the Yellow River, Shanghai, and Nanjing. Based on samples and experiments on the behavior of pollutants, it systematically discusses the regulation of trace metals' distribution, accumulation, and migration, associated with the cause of formation demonstration. The author subsequently uses the acquired data to review the evolving trend of trace metal behaviors in natural systems (river or lake water, sediments, and soils), develops suggestions for the prevention of their negative effects, and devise treatments. Moreover, he proposes solutions to difficult research issues such as trace metal speciation extraction, and an analysis, along with operational procedures. Given its scope, the book will provide a valuable guide for researchers and engineers in relevant disciplines of the environmental sciences and engineering, and for environmental policymakers to consult in practices.

R3,330 Discovery Miles 33 300 Ships in 12 - 17 working days

Microbial quality of water is a prime public health concern in today's world. To protect public health, the World Health Organization and the U.S. Environmental Protection Agency have established microbial pollution indicator standards and recommended routine monitoring of water for both total and fecal coliforms (Dufour, 1984, U.S. EPA 1986,1994, WHO 1993). However, the adequacy of current water quality standards to indicate the presence or absence of human pathogens is still questionable. For example, human viruses are more resistant to sewage treatment processes and environmental conditions than bacterial indicators and therefore may pose a substantial threat. It is now recognized that the absence, or a low concentration, of indicator organisms in water may not adequately reflect the absence of human viruses. In our previous study of southern California coastal waters, we found over 30% of coastal waters tested contained human viruses, and the presence of these viruses did not correlate with an elevated level of bacterial indicators (Jiang et al. 2000). The goal of this research is to develop and validate a molecular method for rapid and specific detection of microbial contaminants including human viruses and bacterial indicators in treated sewage effluents and receiving waters. Research Outcomes An extensive search and review of current state of technology for molecular alternatives to indicator and viral pathogen detection was conducted. The results indicate that although real-time PCR methods have been widely applied in the clinical research for detection of human viruses, environmental application of this method is very limited. In addition, there is an urgent need for a method for efficient concentration and purification of human viruses in complex environmental matrixes. During this study, we have designed, tested and optimized real-time quantitative PCR method using specific and degenerate primers and probes targeting at adenoviruses and enterococci, respectively. Experimental testing of real time PCR primers and probes for adenoviruses demonstrated reproducible results at efficiency greater than 90% over a 5-log dynamic range of target concentration. The enterococci real time PCR was efficient at 99% of the time and over a 7-log dynamic range of target concentration. Application of these methods to sewage effluents and coastal waters demonstrated that real-time PCR methods are more sensitive than culturing methods at detection of targets, suggesting a great potential for real-time quantification of microbial contaminants in environments. However, real-time PCR based method, like other genome based detection technology, overestimates the concentration of infectious viral concentration in the environment. In addition to the method development for real-time PCR detection, we have also sampled and isolated human adenoviruses from Newport Bay, California using human embryonic kidney cells, 293A. Cloning and sequencing of selective environmental adenovirus hexon gene suggested that most of the viruses recovered from the environment belong to adenovirus serotype 40 (66%). This result is in agreement with clinical data on the load of viral shedding in feces. Since adenovirus serotypes 40 and 41 are the major cause of childhood diarrhea, the result of this investigation indicates the importance of monitoring water for viral quality. Comparison of four different tissue culture cell lines for their sensitivities to adenoviruses infection has demonstrated that the genetically engineered 293A cells are the most efficient at recovery of adenoviruses 40. This result is a significant contribution to our ability to assay for infectious adenoviruses in environmental samples.

One of the most controversial issues of the water sector in recent years has been the impacts of large dams. Proponents have claimed that such structures are essential to meet the increasing water demands of the world and that their overall societal benefits far outweight the costs. In contrast, the opponents claim that social and environmental costs of large dams far exceed their benefits, and that the era of construction of large dams is over. A major reason as to why there is no consensus on the overall benefits of large dams is because objective, authoritative and comprehensive evaluations of their impacts, especially ten or more years after their construction, are conspicuous by their absence. This book debates impartially, comprehensively and objectively, the positive and negative impacts of large dams based on facts, figures and authoritative analyses. These in-depth case studies are expected to promote a healthy and balanced debate on the needs, impacts and relevance of large dams, with case studies from Africa, Asia, Australia, Europe and Latin America.
