Environmental pollution is an emerging global public health problem of both developing and developed nations. Such pollution is a major risk factor for many illnesses, including nervous system disorders. This book combines the highlights the effects of environmental pollution on brain biology. It will be a thorough overview of the pathophysiological and oxidative stress mechanisms and how environmental pollution affects the brain biology. The author discusses environmental pollution and brain development, memory, autism, hearing and vision loss and brain cancer. Several chapters address controversial topics such as the effect of Electromagnetic Field Radiation (RF-EMFR).
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.

The book addresses the theoretical implications of time-sensitivity on the remote sensing process, assessments or descriptions of methods for expediting the delivery and improving the quality of information derived from remote sensing, and describes and analyzes time-sensitive remote sensing applications, with an emphasis on lessons learned. This book is intended for remote sensing scientists, practitioners (e.g., emergency responders or administrators of emergency response agencies), and students, but will also be of use to those seeking to understand the potential of remote sensing to address a range of pressing issues, particularly natural and anthropogenic hazard response.
Microbial bioremediation and biodegradation in environmental monitoring offers an environmentally friendly approach for the monitoring and effective removal of contaminants. Various aspects of microbial-mediated bioremediation take advantage of the microorganisms' ability to transform noxious compounds into utilizable intermediates and value-added products. Different microbial metabolites such as enzymes, biosurfactants, emulsifiers, organic acids, and solvents play significant roles in the decontamination of radioactive and heavy metals, chemical pesticides, and organic contaminants such as dyes and hydrocarbons in environmentally safe manners. Recent advancements in biochemical engineering, OMICS and genetic modification, and synthetic-biology pave ways for identifying indicator microbial strains, mechanisms of remediation, and the development of tailor-made microbe-metabolites for future applications. Microbial biotechnology in environmental monitoring and bioremediation thus represent a new way to rehabilitate and reconstruct "damaged" ecosystems.This work summarizes the latest research in the field of environmental bioremediation and offers fascinating insights on the behaviours of these unique microorganisms. It also presents exciting, new perspectives for the application of microbes in environmental protection. It is suitable for students, scholars, researchers and organizations involved in environmental protection.
"From the Introduction: " The Acid Precipitation Act of 1980 established an Interagency Task Force to develop a comprehensive research program for investigation of acid precipitation issues. The National Acid Precipitation Assessment Program (NAPAP) was subsequently established to develop the necessary data and provide a framework for policy recommendations in regard to acid precipitations. One aspect of the overall acid deposition issue is to understand the role and significance of direct emissions of acidic materials. As such, it is necessary to identify the major industrial sources of direct emissions of acidic material (e.g., sulfates, chlorides) and to evaulate the control of these materials. In addition, it is important to know if the most cost-effective methods for reducing acidic emissions differ from those for controlling acid deposition precursors (SO2, NOx, and VOC). Accordingly, the objectives of this study were: 1) to identify and characterize stationary combustion and industrial sources of directly emitted acidic materials in the United States; 2) to evaluate the technical feasibility of control techniques for these sources; and 3) to estimate the costs of applying these control technologies. This assessment was conducted via review and analysis of existing data including the preliminary control strategies evaluated by the Interagency Task Force. The potential for emissions from transportation sources was not examined in this study. Results of the study can be used to evaluate the merits of controlling directly emitted acidic materials as part of a policy evaluation of overall acid deposition control strategies. For example, if it were determined that for a region localemissions of directly emitted acid materials were more significant than lon

Throughout the 1970s and the 1980s, energy policy has been a hotly debated topic. Governments around the world have struggled to respond to a changing energy market. Yet the policy-making process is all too often distorted by self-interest groups who are informed by narrow, technical research. The question addressed by this volume is one of the most timely and critical of the energy-related questions: How much longer can we rely on petroleum as a transportation fuel? This book, which includes a subset of papers commissioned for an unusual symposium (Alternative Transportation Fuels of the 1990s and Beyond, July 17-19, 1988), addresses the broader issues of transportation-fuel policy in regard to energy security, economic growth, and environmental quality. While many conferences have addressed the subject of alternative fuels, their scope has been intensive and narrow, focusing on a few specific areas in the spectrum of possibilities. This conference was the first in many years to offer such a broad exploration of alternative fuels. Presenters included influential executives and administrators from the Department of Energy, and the motor vehicle and energy industries; federal, state, and local governments; environmental groups as well as leading researchers in the fields of air quality analysis, motor vehicle technology, and energy policy. In addition to an introduction and conclusion by Daniel Sperling, a total of 17 papers are presented in this volume. What is most exceptional and exciting about this collection is the presentation of contrasting views and the sharing of this wealth of information with a broader audience. Examined here are global fuel strategy, ethanol fuels in Brazil, alternative fuels as a solution to the air quality problem, Chevron's view of the future of oil, and the role of government in promoting alternative transportation fuels. Methanol, compressed natural gas, and hydrogen-powered and electric vehicles are also discussed. In addition to the analytical papers, the volume also includes a short article representing the viewpoint of an environmentally minded citizen. This book should appeal to any individual involved or interested in this important area. Researchers will appreciate the opportunity to consider so many well-researched but varying perspectives. It will be essential--and perhaps should be required reading--for policy makers, providing them with an overview of the issues and helping them make more intelligent, effective, and strategic choices. For the general public--those who are affected by energy and transportation policies--it is a unique opportunity to gain a broad understanding of our transportation fuel options and their environmental and economic consequences.
This volume offers a review of measures taken at different levels to prevent oil inputs to the North Sea from sources such as shipping and oil installations. A range of data from satellites, remote sensing, aerial surveillance, in-situ monitoring, oil spill sampling and beached bird surveys presents a comprehensive portrait of trends in oil pollution over many years. Topics include Bonn Agreement-based actions to eliminate illegal and accidental pollution from ships, OSPAR monitoring of oil installations, EMSA CleanSeaNet activities, and an internationally approved common standard for oil spills presented by the Bonn-OSINet. A chapter on the role of the IMO in preventing oil pollution from ships provides an international context, while others discuss efforts being made at the national level. A decadal review of the state of the North Sea prepared by OSPAR supports the view that there has been a significant reduction of oil inputs to the sea. This thorough review addresses national and international agencies and government bodies, as well as policymakers and practitioners in the fields of shipping, ports and terminals, oil extraction and marine management. Further, it provides researchers with essential reference material on tools and techniques for monitoring oil pollution and offers a valuable resource for undergraduate and post-graduate students in the field of marine oil pollution.
Subjects extensively covered include asbestos, carbon dioxide,
lead, nuclear accidents, non-ionizing radiation, stratospheric
ozone, and visibility.
This book aims to provide comprehensive and systematic introduction and summary of corrosion characteristics, mechanisms, and control methods of candidate alloys in sub- and supercritical water environment.

At the same time, research status of candidate materials, and development and application trends of several corrosion-resistant alloys are summarized. Then, corrosion characteristics of Ni-Cr, Ni-Cr-Mo, Ni-Fe-Cr and Ni-Fe-Cr-Mo-Cu corrosion-resistant alloys, FeCrAl alloy, and Zircaloy are discussed in detail, including the corrosion rate, the structure and composition of oxide film, and the effects of various surface treatment processes, etc. More specifically, it also investigates corrosion behavior of Ni-based alloy, Fe-Ni-based, and stainless steels in supercritical water. The effects of aggressive species on the corrosion behavior of Ni-base alloys are also explored in supercritical water. Readers will further discover the total corrosion processes and mechanisms of typical candidate alloys in sub- and supercritical water environment. Finally, the work explores the corrosion control methods such as ceramic coatings and passivation processes in supercritical water oxidation and in subcritical water, respectively. Future challenges and development trends of corrosion research of candidate materials in sub- and supercritical water environments are covered at the end of this book. It offers valuable reference for theoretically guiding material selection and design and operating parameter optimization of key equipment in the sub- and supercritical water technologies. The book is written for senior undergraduates, graduate students, scholars, and researchers who are interested in corrosion behavior of candidate materials of supercritical water oxidation system, supercritical water gasification system, and nuclear reactor.
In order to effectively address global warming, many countries have significantly reduced the amount of carbon dioxide emissions that are put into the atmosphere. From the perspective of industrial structure, this volume examines the emission reduction potentials and abatement costs in China. By making an empirical analysis of the emission reduction, the author proposes some practical strategies. The book comprehensively summarizes related theories and research of contaminant disposal modeling, and estimates the shadow price of interprovincial CO2 emissions, the emission reduction potential of different regions, and the marginal emission reduction cost based on the parametric model. It finally puts forward the strategy to adjust the industrial structure in China. The book hence provides solid evidence for policy-makers to help mitigate CO2 emissions through industrial restructuring strategy.
First published in 1985, Emissions Trading was a comprehensive review of the first large-scale attempt to use economic incentives in environmental policy in the United States; since its publication it has consistently been one of the most widely cited works in the tradable permits literature. The second edition of this classic study of pollution reform considers how the use of transferable permits to control pollution has evolved over the last twenty-five years. Initially little more than an academic curiosity, the use of tradable permits eventually became the centerpiece of both the U.S. program to control acid rain and the European approach to controlling greenhouse gases. The second edition of Emissions Trading skillfully weaves together a vast amount of theoretical and empirical information, offering a thorough survey of what we have learned about this important environmental policy instrument after twenty-five years of theorizing, conducting empirical research, and evaluating the implementation experience. outlines what has been learned to date about the appropriate niche for this instrument and identifies best practices for the design of effective programs.
'Beautiful, like a muddy journey through time . . . a really important book' RAYNOR WINN, author of The Salt Path Lisa Woollett has spent her life combing beaches and mudlarking, collecting curious fragments of the past: from Roman tiles and Tudor thimbles, to Victorian buttons and plastic soldiers. In a series of walks from the Thames, out to the Kentish estuary and eventually to Cornwall, she traces the history of our rubbish and, through it, reveals the surprising story of our changing consumer culture. Timely and beautifully written, Rag and Bone shows what we can learn from what we've thrown away and urges us to think more about what we leave behind.
This book introduces the theory and applications of nanometer photocatalysis, and it briefly presents the concept of photocatalysts, photocatalytic reaction mechanisms and kinetics, and photocatalytic reactor design. In addition, the use of photocatalysis in the control of flue-gas pollutants is discussed in detail. The book also describes how a photocatalytic reactor is designed and implemented to evaluate the photocatalytic oxidation capacity of different photocatalysts on elemental mercury in a simulated flue gas. After that, the effect of photocatalysts on the SO2, NOx and Hg removal in the flue gas is studied. Photocatalytic cleaning technology can be applied not only in gas pollutant cleaning at power plants, but also in wastewater purification. Readers gain a comprehensive understanding of possible mercury emission control methods and the industrial applications of these technologies.
Eight case studies from around the United States involving the reduction of trihalomethane in water treatment facilities. Includes information on finished water quality, treatment plant performance, and costs for each example. "From the Introduction: " In order to comply with the maximum contaminant level (MCL) for total trihalomethanes (TTHM), many utilities have modified their pre-oxidation and disinfection practices by switching to alternative oxidants and disinfectants in place of free chlorine. Examples of such modifications include the use of chlorine dioxide (C102), ozone (O3) or potassium permanganate (KMnO4) as pre-oxidants and disinfectants with free chlorine used as the final disinfectant, and the use of free chlorine as a pre-oxidant and disinfectant with combined chlorine (e.g., monochloramine (NH2Cl)) used as the final disinfectant. In fact, the final rule establishing an MCL for TTHM in November 1979 (EPA, 1979) was followed in March 1982 by a guidance document for utilities in which the EPA proposed treatment technologies which could be used to control trihalomethane (THM) levels. Three of the five "generally available" treatment methods included the use of chloramines or chlorine dioxide as alternative or supplemental disinfectants or oxidants, and the substitution of chloramines, chlorine dioxide, and potassium permanganate as pre-oxidants in place of chlorine. The proposal also included, as an additional treatment method which should be considered but which was not identified as "generally available," the use of ozone as an alternate or supplemental disinfectant or oxidant. These proposals were subsequently adopted by EPA in February 1983 (EPA, 1983). At the time
Developing countries recognize the importance of their future role in responding to the uncertainty posed by global climate change through appropriate technical, institutional, and policy measures. The ongoing global negotiations are now in a critical phase. A comprehensive assessment and understanding of issues relevant to developing countries, such as greenhouse gas emissions inventories, contribution of developing countries to greenhouse gas emissions, projected climate change, impacts of climate change on the ecosystems and developing economies, mitigation opportunities, and potential socio-economic implications for developing countries, is necessary in order to address the emerging climate change. This book presents the alternative perspectives of developing countries on opportunities to benefit from the current and emerging global negotiations, institutions, and mechanisms to address climate change. Analyses show that the developing countries, with appropriate policy and institutional responses, could benefit from the global programs for mitigating the climate change. A comprehensive and simplified guide to assist negotiators and policy makers from developing countries, as well as researchers, is provided. The unique feature of this book is that it provides a comprehensive coverage of different issues such as greenhouse gas emissions, mitigation analysis, impacts and adaptation, policy options, emerging global institutions and mechanisms, and alternative perspectives of developing countries. The book provides basic information, analysis, and interpretation of various aspects relevant to climate change and will be a valuable asset to researchers, negotiators, policymakers, and environmental groups engaged in the analysis and discussion of climate change.

Contributions by experts provide a comprehensive discussion on the latest developments in the detection and analysis of contaminants, enabling researchers to understand the evolution of these pollutants in real time and develop more accurate source apportionment of these pollutants. The contents of this book will be of interest to researchers, professionals, and policy makers alike.
There are thousands of substances manufactured in the United States to which the public is routinely exposed and for which toxicity data are limited or absent. Some insist that uncertainty about the severity of potential harm justifies implementing precautionary regulations, while others claim that uncertainty justifies the absence of regulations until sufficient evidence confirms a strong probability of severe harm. In this book, Levente Szentkiralyi overcomes this impasse in his defense of precautionary environmental risk regulation by shifting the focus from how to manage uncertainty to what it is we owe each other morally. He argues that actions that create uncertain threats wrongfully gamble with the welfare of those who are exposed and neglect the reciprocity that our equal moral standing demands. If we take the moral equality and rights of others seriously, we have a duty to exercise due care to strive to prevent putting them in possible harm's way. The Ethics of Precaution will be of great interest to researchers, educators, advanced students, and practitioners working in the fields of environmental political theory, ethics of risk, and environmental policy.
Revised, expanded, and updated, this second edition of Statistics for Environmental Science and Management is that rare animal, a resource that works well as a text for graduate courses and a reference for appropriate statistical approaches to specific environmental problems. It is uncommon to find so many important environmental topics covered in one book. Its strength is author Bryan Manly's ability to take a non-mathematical approach while keeping essential mathematical concepts intact. He clearly explains statistics without dwelling on heavy mathematical development. The book begins by describing the important role statistics play in environmental science. It focuses on how to collect data, highlighting the importance of sampling and experimental design in conducting rigorous science. It presents a variety of key topics specifically related to environmental science such as monitoring, impact assessment, risk assessment, correlated and censored data analysis, to name just a few. Revised, updated or expanded material on:
There are numerous books on environmental statistics; however, while some focus on multivariate methods and others on the basic components of probability distributions and how they can be used for modeling phenomenon, most do not include the material on sampling and experimental design that this one does. It is the variety of coverage, not sacrificing too much depth for breadth, that sets this book apart.
This book presents materials and physical methods for carbon dioxide sequestration. Materials include nanosponges, titanium oxide/zeolite hybrids, classical absorbents, metal oxides, ionic liquids, alkaline soils and metal organic frameworks. Methods include cryogenic capture, adsorption, solvent dissolution and soil sequestration.
This book highlights recent findings of membrane - based dye removal methods along with the application of photocatalytic, nanofiltration and ultrafiltration membrane including membrane - based fibers, metal-organic frameworks, polyethersulfone, ceramic, etc. Among water and wastewater pollutants, dyes have been normally observed and detected in various aquatic solutions, including rivers and lakes. Aesthetic pollution, toxicity, persistent, and carcinogenicity are some of the adverse effects of dyes entering the ecosystem. Although dyes have brought a colourful world, their presence in the environment are responsible for adverse effects on the planet. Diverse physical, chemical and biological methods are available to treat dye contaminated water. This book presents membrane separation technology that has been developed in the past decade to treat different wastewaters, and owning to its effective performance, has garnered the attention of academia and industry alike. |
