The enduring changes in the aquatic environment and the increasing influx of contaminants call for novel conceptual and methodological approaches to relating chemical pollution and ecological alterations in ecosystems. This volume highlights the latest advances concerning the sampling, analyses, occurrence, bioavailability, and effects of emerging and priority pollutants in European rivers, the current status of the River Management Plans in Europe, and the applicability of the newly developed techniques for water monitoring purposes. The topics are discussed in the context of the EU Water Framework Directive, evaluating their shortcomings and providing a basis for doing away with them. Linking scientific research and river management practices, this book is an invaluable source of information for environmental chemists, aquatic scientists, ecologists and water managers.
Originally published in 1993, this volume describes a complementary selection of tests to those described in the companion volume Basic Mutagenicity Tests (Cambridge University Press, 1990). These supplementary tests were used to assess risks of in vitro mutagenicity in those instances where the basic tests were inconclusive. As such, these tests had an important role in the assessment of the safety of compounds, drugs and chemicals. These supplementary test and guidelines, originally drawn up by the United Kingdom Environmental Mutagen Society (UKEMS) were fully revised in this publication to take full account of different regulatory guidelines and scientific advances. This volume will be of value to anyone with aninterest in regulatory affairs, mutagenicity testing and the registration of chemical products in the UK and Europe.
Over the last several years, there has been much discussion on the interrelation of CO2 emissions with the global warming phenomenon. This in turn has increased pressure to develop and produce more fuel efficient engines and vehicles. This is the central topic of this book. It covers the underlying processes which cause pollutant emissions and the possibilities of reducing them, as well as the fuel consumption of gasoline and diesel engines, including direct injection diesel engines. As well as the engine-related causes of pollution, which is found in the raw exhaust, there is also a description of systems and methods for exhaust post treatment. The significant influence of fuels and lubricants (both conventional and alternative fuels) on emission behavior is also covered. In addition to the conventional gasoline and diesel engines, lean-burn and direct injection gasoline engines and two-stroke gasoline and diesel engines are included. The potential for reducing fuel consumption and pollution is described as well as the related reduction of CO2 emissions. Finally, a detailed summary of the most important laws and regulations pertaining to pollutant emissions and consumption limits is presented. This book is intended for practising engineers involved in research and applied sciences as well as for interested engineering students.

The author explains the physical and chemical basis before proceeding to the practical performance. This publication provides the reader with the knowledge necessary to critically analyze and investigate emission measurement techniques. It will be of great interest to researchers and engineers in the fields of environmental technology and air pollution control. It will assist in the choice of the most appropriate instruments for various purposes and circumstances.
Although fossil fuels remain the primary global energy source, developing and expanding economies are creating an ever-widening gap between supply and demand. Efficient energy management offers a cost-effective opportunity for both industrialized and developing nations to limit the enormous financial and environmental costs associated with burning fossil fuels. The implication of photovoltaic systems in particular presents the potential for clean and sustainable electrical energy to be generated from an unrestricted source. Energy Management in Buildings Using Photovoltaics demonstrates how adopting 'best practices' for energy management and harvesting can reduce the need to construct new generating facilities. Illustrated with figures, tables and photos, Energy Management in Buildings Using Photovoltaics provides an introduction and step by step instructions on designing and planning photovoltaic systems and energy policies for both residential and industrial buildings. With particular focus on the example of provided by European industry, the creation of energy efficient systems is explored including chapters on: Zero Energy Buildings, Photovoltaics Technology, and Connection of the Network By presenting this topic from basic introduction to highly technical analysis, Energy Management in Buildings Using Photovoltaics acts a study guide for postgraduate students as well as a key point of reference for researchers and technical consultants in the field of photovoltaic systems.
Based on detailed research funded across two continents and involving universities in Argentina, Spain and the UK, this book sets out an innovative, multidisciplinary approach to assessing both environmental and social risks in a given territorial area. Using data from a number of Ibero-American nations, the study combines environmental, socio-economic and geographic factors to construct a set of spatial and technical indicators that measure the social vulnerability and industrial hazardousness of a defined area. Aggregating these indicators in a geographic information system (GIS) allows researchers to assess the potential risk to which a certain area and its population are subject as a result of the environmental deterioration caused by co-located industrial activity.
Groundwater Contamination in Coastal Aquifers: Assessment and Management first describes groundwater contamination in coastal aquifers and then delves into specific topics surrounding various hydrogeochemical processes. Next, the book covers case studies of groundwater quality assessment using recent techniques, explains the various pollutants and contaminants in coastal aquifers, and covers management and remediation methods to control contamination in coastal aquifers. This key reference encompasses various topics in broader perspectives on groundwater contamination in coastal aquifers, providing a significant contribution to the field of hydrogeology.
Environmental chemistry is a fast developing science aimed at deciphering fundamental mechanisms ruling the behaviour of pollutants in ecosystems. Applying this knowledge to current environmental issues leads to the remediation of environmental media, and to new, low energy, low emission, sustainable processes. Chapters review analysis and remediation of pollutants such as greenhouse gases, chiral pharmaceuticals, dyes, chlorinated organics, arsenic, toxic metals and pathogen in air, water, plant and soil. Several highlights include the overlooked impact of air pollutants from buildings for health risk, innovative remediation techniques such as bioreactors for gas treatment, electrochemical cleaning of pharmaceuticals, sequestration on Fe-Mn nodules, phytoremediation and photocatalytical inactivation of microbial pathogens. This book will be a valuable source of information for engineers and students developing novel applied techniques to monitor and clean pollutants in air, wastewater, soils and sediments. "

Recent developments in air pollution modeling and its application are explored here in contributions by researchers at the forefront of their field. The book is focused on local, urban, regional and intercontinental modeling; data assimilation and air quality forecasting; model assessment and evaluation; aerosol transformation; the relationship between air quality and human health and the interaction between climate change and air quality. The work will provide useful reference material for students and professors interested in air pollution modeling at the graduate level as well as researchers and professionals involved in developing and utilizing air pollution models.
Mathematical models are the effective tool to solve different tasks predicting pollutant movement. The finite difference method is the oldest, but still remains widely used in hydrogeological practice. However, this method is not very useful to construct the new transport models because it cannot approximate the shape of remediation elements exactly. Therefore the book is concerned with the FEM (Finite Element Method) and BEM (Boundary Element Method), and also with the comparison of advantages of these methods in groundwater hydrology. The combination of the BEM and the random-walk particle tracking method, which seems to be a very useful tool to model the spread of pollution in groundwater, are also presented. The computer programmes have been developed on the basis of the theoretical backgrounds of these methods. They use the Visual C++ programming language for Windows 95/NT platform and will be included in the book.
Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environmental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environmental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities of waste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.
A Practical Guide to Environmental Crime Scene Investigations Releasing contaminants into the environment whether deliberate or unintentional can be thought of as a crime against the environment. The role of environmental forensics is to identify and prevent environmental pollution, or crimes. Environmental Forensics Fundamentals: A Practical Guide examines this growing field, and provides environmental professionals looking to specialize in environmental forensics with the materials they need to effectively investigate and solve crimes against the environment." Pointing the Finger at Environmental Crime" Environmental forensics uses "fingerprinting" techniques in order to assess and analyze contamination sites. Fingerprinting can reveal the source of contamination, as well as how, where, and when the contamination was released. This handy guidebook outlines the proven techniques, applications, and resources needed to efficiently investigate environmental crimes and become successful in this emerging field." Learn the Basics from a Single Source" Divided into three main parts, the first part of the book examines the role of evidence in forensic investigations and court proceedings. It highlights general forensic concepts and offers guidelines for obtaining defensible evidence. The second part details environmental forensic investigative techniques. It includes a step-by-step guide that enables the reader to apply the techniques in practice. The final section covers strategy building. It presents real case studies, as well as key principles and concepts for strategy building, and addresses the most common challenges faced in environmental forensics. Environmental Forensics Fundamentals: A Practical Guide provides information on cutting-edge scientific techniques that investigate the source and age of environmental pollution and solve environmental crimes. It examines the principles behind each main forensic technique. It also offers guidance on what to look for in order to successfully apply the techniques and interpret results. In addition, the author provides relevant sources where more information can be found."

Does a connection exist between environmental degradation, resource
scarcity and violent conflicts? Global environmental changes, such
as climate change and sea level rise, shortage of fresh water and
rapid soil degradation increasingly highlight the dimensions of
environmental change in foreign and security policy. To reverse
these negative environmental consequences over the long term,
comprehensive and preventive policy approaches are urgently
required.
Finishing this book is giving me a mixture of relief, satisfaction and frus tration. Relief, for the completion of a project that has taken too many of my evenings and weekends and that, in the last several months, has become almost an obsession. Satisfaction, for the optimistic feeling that this book, in spite of its many shortcomings and imbalances, will be of some help to the air pollution scientific community. Frustration, for the impossibility of incorporating newly available material that would require another major review of several key chap ters - an effort that is currently beyond my energies but not beyond my desires. The first canovaccio of this book came out in 1980 when I was invited by Computational Mechanics in the United Kingdom to give my first Air Pollution Modeling course. The course material, in the form of transparencies, expanded, year after year, thus providing a growing working basis. In 1985, the ECC Joint Research Center in Ispra, Italy, asked me to prepare a critical survey of mathe matical models of atmospheric pollution, transport and deposition. This support gave me the opportunity to prepare a sort of "first draft" of the book, which I expanded in the following years."
Dry sulfurization processes offer the significant advantages of low capital and low operating costs when compared to wet desulfurization. They hold great potential for the economical reduction of sulfur emissions from power utilities that use high-sulfur coal. Dry Scrubbing Technologies for Flue Gas Desulfurization represents a body of research that was sponsored by the State of Ohio's Coal Development Office for the development of technologies that use coal in an economic, environmentally-sound manner. One of the project's major goals was the development of dry, calcium-based sorption processes for removing sulfur dioxide from the combustion gases produced by high-sulfur coal. Dry Scrubbing Technologies for Flue Gas Desulfurization highlights a number of fundamental research findings that have had a significant and lasting impact in terms of scientific understanding. For example, the experimental investigation of the upper-furnace sulfur capture obtained time-resolved kinetic data in less than 100 millisecond time-scales for the first time ever, thereby revealing the true nature of the ultra-fast and overlapping phenomena. This was accomplished through the development of a unique entrained flow reactor system. The authors also identify a number of important areas for future research, including reaction mechanisms, sorbent material, transport effects, modeling, and process development. Dry Scrubbing Technologies for Flue Gas Desulfurization will appeal to both chemical and environmental engineers who examine different ways touse coal in a more environmentally benign manner. It will make an essential reference for air pollution control researchers from coal, lime, cement, and utility industries; for government policy-makers and environmental regulatory agencies; and for those who teach graduate courses in environmental issues, pollution control technologies, and environmental policy.
Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy, and significant areas of accomplished or needed endeavor in the total field of xenobiotics in any segment of the environment, as well as toxicological implications.
Excessive noise levels are generally acknowledged to have adverse effects on our environment. Studies indicate that excessive noise levels can cause fatigue in exposed individuals, lower efficiency and productivity, impaired speech communication, and hearing loss. Excessive noise is almost everywhere today - in the office, in schools, hospitals and other institutional facilities, in all classes of public buildings, and in our factories. INDUSTRIAL NOISE High noise levels in factories can make speech communication in the plant difficult and at times impossible. Foremen are often unable to hear warning shouts from co-workers. The problem of hearing loss due to excessive noise exposure is of particular concern to industry, and to the federal government. In the early 1970s, the United States Congress passed the Occupational Safety and Health Act (OSHA) which sets criteria for health hazards and established limits for noise exposure of industrial workers. The OSHA Noise Standard was amended in 1982 to require audiometric testing of all employees exposed to noise levels of 85 dB or above for eight hours. A NOISE IN COMMERCIAL AND INSTITUTIONAL BUILDINGS While noise levels in offices, stores, schools, and other commercial and institutional buildings seldom reach those encountered in many industrial environments, they often reach levels which are distracting to the occupants of such buildings. Impairment of speech communica tion among workers, or inversely the lack of speech privacy, are both deterrents to effiCiency and productivity and are detrimental to the occupants' comfort and sense of well-being."
Is economic growth good for the environment? A number of economists have claimed that economic growth can benefit the environment, recruiting political support and finance for environmental policy measures. This view has received increasing support since the early 1990s from empirical evidence that has challenged the traditional environmentalist's belief that economic growth degrades the environment. This book reviews the theoretical and empirical literature on growth and the environment, giving an in-depth empirical treatment of the relationship between the two. Various hypotheses are formulated and tested for a number of indicators of environmental pressure. The test results indicate that alternative models and estimation methods should be used, altering previous conclusions about the effect of economic growth on the environment and offering an insight into the forces driving emission reduction in developed countries.
Land is fundamental to the human life. The upper layer of land is a non-renewable resource, and source of food. Therefore, land health is essential to long-term food security and to promote sustainable livelihoods. On account of urbanization, industrialization and population growth, land pollution is one of the major issues worldwide. As a result, land pollution is continuing across the world, and has been linked with a wide range of potentially toxic contaminants at rates that deteriorate land quality. Land pollution can result either anthropogenic activities or natural activities. The major contaminants of land pollution are metalloids, petroleum hydrocarbon, radioactive elements, polyaromatic hydrocarbons (PAHs), Pesticide, other organic pollutants, etc. that comes from different types of sources. In urban and peri-urban areas, irrigation of agricultural land with polluted water is also a reason of land pollution. Therefore, land security is an important issue for future sustainability. Its remediation and management are important issue worldwide to protect land quality and functions. Land pollution means degradation of earth's surface. Polluted land comes under the category of degraded land. Hence, the remediation of polluted land is essential for regaining biodiversity and ecosystems services and thereby achieving United Nations-Sustainable Development Goals (UN-SDGs).This fact showed the need to develop research into land remediation. Bio-inspired land remediation has undergone a huge development. Therefore, Biomanagement has a lot of potential to secure upper earth's surface through the land remediation programs targeted during the United Nations Decade on Ecosystem Restoration (2021-2030). This book explores the remediation of land pollution that includes Phytoremediation, Bioremediation (bacterial remediation and fungal remediation), Vermiremediation, Biochar-based remediation and other Bio-inspired remediation. This book will be a remarkable asset for research scholars, environmentalists, ecological scientist, agriculturist, practitioners, policy makers, entrepreneurs, and other stakeholders alike.
"Field screening" indicates field analytical tools, and (quick) methods and strategies for on-site or in-situ environmental analysis and assessment of contamination. "Field screening" includes not only field analytical methods, such as mobile laboratories, portable analyses, detectors, sensors, or noninvasive techniques, but also reconnaissance strategies and problems of measurement in heterogeneous media, using, among others, new geotechnical and geophysical instruments. This volume contains both oral and poster contributions to the Second International Conference on Strategies and Techniques for the Investigation and Monitoring of Contaminated Sites, "Field Screening Europe 2001," held in Karlsruhe, May 14 - May 16, 2001. As an integrated study of environmental contamination, "field screening" has become a more and more important part of environmental monitoring and the assessment of chemical contaminations. Recent developments are presented in these proceedings. Audience Environmental engineers, geo-scientists, chemists, biologists, soil scientists, hydrologists and geophysicists.
The determination of the hazards resulting from the accidental or deli berate contamination of terrestrial and aquatic environments is in most countries still lirnited to the detection and quantification of the suspected pollutants by chemical analyses. Such an approach is unfortunately hampered by the following constraints : the costs as weil as the technical difficulties of analyzing every individual chemical which may be present in the sampies, and the difficulty of assessing the hazards and risks of environmental contaminations from a set of chemical data. During the last decades the scientific and regulatory community has gradually realized that biological methodologies have to be taken into consideration for an ecologically meaningful assessment of the toxicological hazards of contaminants. Effect evaluations obtained with biological techniques indeed integrate the impact of all the contaminants to which living biota are exposed. Bioassays with selected test species representative for the biological commumtles of the environments under consideration, are now applied more or less regularly to determine toxic and genotoxic effects. Taking into account the species specific and chemical specific character of toxicity to biota, the necessity of a "battery of tests" approach with species of different trophic levels is currently also generally accepted and implemented. It is dear that a balanced partnership between chemical, biological, toxicological and microbiological analyses is always the best strategy for generating the broadest information base on environmental hazards. |
