This research aimed to identify and understand mechanisms thar underlie the beneficial effect of ozonation on removal of pesticides and other micropollutants by Granular Activated Carbon (GAC) filtration. This allows optimization of the combination of these two processes, termed Biological Activated Carbon filtration. The study concluded that ozonation significantly improves removal of atrazine by GAC filtration not only due to the wellknown effect of oxidation of atrazine, but also due to the effect of partical oxidation of Background Organic Matter (BOM) present in water. Ozone-induced oxidation of BOM was found to improve adsorption of atrazine in GAC filters. Biodegradation of atrazine in these filters wasnot demonstrated. Higher GAC's adsorption capacity for atrazine and faster atrazine's mass transfer in filters with ozonated rather than non-ozonated influent were explained as due to ozonated BOM. Both can be attributed to enhanced biodegradability and reduced adsorbsbility of partially ozidated BOM compounds, resulting in their increased biodegradation and decreased adsorption in GAC filters.
As the field of environmental management moves into the future, its focus will be on reducing or eliminating waste pollution streams. Engineers, technicians, and maintenance personnel must develop proficiency and improved understanding of pollution prevention and waste control to cope with the challenges of this important area. Pollution Prevention: The Waste Management Approach to the 21st Century covers - in a thorough and clear style - the fundamentals of pollution prevention and their application to real-world problems. The book is divided into three parts: Process and Plant Fundamentals, Pollution Prevention Principles, and Pollution Prevention Applications. Part one examines the general subject of process and plant fundamentals, equipment and calculation, process diagrams and economic considerations. Part two covers the broad subject of pollution prevention options, including chapters on source reduction, recycling, treatment methods, and ultimate disposal. Part three contains chapters devoted to specific industrial applications involving pollution prevention. The text is generously supplemented with illustrative examples. Applying pollution prevention strategies - the most viable environmental management option of the future - offers a more cost-effective means of minimizing the generation of waste. Pollution Prevention: The Waste Management Approach to the 21st Century provides the basic principles required for understanding not only pollution prevention but also waste control.
Fate and transport models are critical components in the determination of the exposure to and risk from hazardous contaminants. Analytical models are preferable because they are generally more accessible, more reliable, and require fewer computational resources. Surprisingly, until today, only a limited number of analytical models have been accessible in the literature.
Interest in phytoremediation as a solution for contaminants in groundwater and soil has exploded. The project documented in Phytoremediation of Hydrocarbon Contaminated Soils presents innovative technology for environmental clean up using in situ treatment. It describes the results of a field study focusing on hydrocarbon contamination, especially polynuclear aromatic hydrocarbons, in surface and near surface soils. The field demonstration used soils contaminated with aged diesel fuels. The random block design enabled the investigators to test the statistical difference in the effects of different vegetated and unvegetated treatments. They tested the degradation of diesel and polynuclear aromatic hydrocarbon components in plots containing three different vegetation treatments, two grasses and a legume, and a non-vegetated control. Part one of the monograph gives a complete and thorough account of the results of the field study. Part two covers the design and potential costs of a full-scale implementation of the demonstration system as well as the performance and potential application of the new technology. Phytoremediation of Hydrocarbon Contaminated Soils supplies quantitative results about the use of vegetation in soil remediation. The information given on the niches and limitations of the technologies allows for a more informed selection of remedial solutions for environmental cleanup.
Phytoremediation is an exciting, new technology that utilizes metal-accumulating plants to rid soil of heavy metal and radionuclides. Hyperaccumulation plants are an appealing and economical alternative to current methods of soil recovery. Phytoremediation of Contaminated Soil and Water is the most thorough literary examination of the subject available today.

This collection reviews the extent of resource debasement and offers solutions for their restoration. The 14-part first section deals with mine management and rehabilitation. Topics include the devastating results of open-cut mining, open-pit mining, lignite surface mining and acid mining. Despite such ruin, the articles reveal the possibilities for reclamation. Part two devotes nine chapters to the management of derelict lands. Reforestation, soil fertility prognosis, and the uses of nitrogen are just a few of the covered subjects. This portion of the book pays special attention to the successful results of remediation in China and Hong Kong. The final division addresses soil contamination and reclamation. There are eleven chapters on subjects that include the single and interactive effects of aluminum, the effectiveness of EDTA/HCI and the value of pig-on-litter compost as a tool for edible crop growth. These and other innovative techniques make Remediation and Management of Degraded Lands a valuable addition to any environmental library.
Pesticde use in agriculture and non-agriculture settings has increased dramatically over the last several decades. Concern about adverse effects on the environment and human health has spurred an enormous amount of research into their environmental behavior and fate. Pesticides in Surface Waters presents a comprehensive summary of this research. This book evaluates published studies that focus on measuring pesticide concentration. The studies chosen include peer reviewed scientific literature, government reports, laboratory studies, and those using microcosms and artificial streams and ponds. The authors used this information to develop their overview of pesticide contamination of surface waters. The exhaustive compilation of data along with the fundamental science make this book essential for those involved in pesticide use, environmental protection, water quality, and human or ecological risk assessment. Pesticides in Surface Waters covers the results of actual studies, sources of pesticides to surface water, fate and transport, and environmental significance. Hundreds of data-packed tables, maps, charts, and drawings illustrate the key points, making research and application easy and cost effective.
From the Preface
"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.

Aerobiology is the study of airborne particles that have an impact on humans and other organisms. Every day, we are exposed to airborne particles, including "natural" particles such as pollen, bacteria, and fungi, and "unnatural" particles, such as asbestos fibers and noxious chemicals. Aerobiology highlights the current interests in this field, primarily the ecology and distribution of airborne particles and their effects on health.
China's rapid industrialisation has led to "an air pollution catastrophe". Concerted efforts to achieve economic growth have led to veiled skies of toxic air and created health and morbidity problems as well as tremendous environmental degradation. China's Air Pollution Problems provides an overview of air pollution in China describing how and why China has ended up in such a dire situation, what the government is doing to address the problem and the difficulties it is encountering in attempting to reduce the pollution. The analysis is based on both grey literature (newspaper articles, NGO reports, Chinese government information) and on academic studies. The grey literature gives a voice to those who suffer from the pollution, their advocates, and government officers, and allows the reader to better grasp the conditions on the ground, and the impact of air pollution among people in different areas in China. The academic literature adds a theoretical perspective and brings these different case studies into a broader context. This book will be of great interest to students of environmental pollution and contemporary Chinese studies looking for an introduction to the topic and also for researchers looking for an extensive list of sources and analysis of China's environmental problems.
Seawater desalination is a rapidly growing coastal industry that is increasingly threatened by algal blooms. Depending on the severity of algal blooms, desalination systems may be forced to shut down because of clogging and/or poor feed water quality. To maintain stable operation and provide good feed water quality to seawater reverse osmosis (SWRO) systems, ultrafiltration (UF) pre-treatment is proposed. This research focused on assessing the ability of UF and other pre-treatment technologies to reduce biofouling in SWRO systems. An improved method to measure bacterial regrowth potential (BRP) was developed and applied at laboratory, pilot and full scale to assess the ability of conventional UF (150 kDa) and tight UF (10 kDa) alone and in combination with a phosphate adsorbent to reduce regrowth potential and delay the onset of biofouling in SWRO. The improved bacterial regrowth potential method employs a natural consortium of marine bacteria as inoculum and flow cytometry. The limit of detection of the BRP method was lowered to 43,000 +/- 12,000 cells/mL, which is equivalent to 9.3 +/- 2.6 g-Cglucose/L. The reduction in bacterial regrowth potential after tight UF (10 kDa) was 3 to 4 times higher than with conventional UF (150 kDa). It was further reduced after the application of a phosphate adsorbent, independent of pore size of the UF membrane. Pilot studies demonstrated that the application of tight UF (10 kDa) coupled with a phosphate adsorbent consistently lowered the bacterial regrowth potential and no feed channel pressure drop increase was observed in membrane fouling simulators (MFS) over a period of 21 days. The study also showed that non-backwashable fouling of UF membranes varied strongly with the type of algal species and the algal organic matter (AOM) they release. The presence of polysaccharide (stretching -OH) and sugar ester groups (stretching S=O) was the main cause of non-backwashable fouling. In conclusion, this study showed that an improved BRP method is suitable for the assessment of SWRO pre-treatment systems and it can be a useful tool to develop potential strategies to mitigate biofouling and improve the sustainability of SWRO systems.

Interest in volatile organic compounds (VOCs) as air pollutants has increased dramatically in recent years. This book covers a number of very topical issues concerning VOCs, including stratospheric ozone depletion due to CFCs, and the properties of alternative substances; the role of VOCs in the photochemical formation of lower atmosphere (tropospheric) ozone; and the problem of the direct toxicity of VOCs such as benzene and formaldehyde. This Issue reviews our current knowledge of VOCs, drawing upon the expertise of renowned experts and major national and international research programmes. It examines man-made and natural sources, as well as pathways and chemical reactions in the atmosphere. It also looks closely at the sources and concentrations of VOCs indoors, where humans are most likely to be exposed to them. Volatile Organic Compounds in the Atmosphere describes techniques used for the calculation of emissions inventories and strategies for control, and explores the many Government policy matters relating to VOCs. It provides readers with in-depth, clearly explained coverage of the many complex scientific and policy issues surrounding VOCs in the atmosphere.
The Handbook of Air Toxics compiles, defines, and clarifies several methods and concepts of airborne toxic substances found in the environment. This comprehensive reference helps regulators, consultants, and other environmental professionals meet the challenges of sampling and analysis, emissions reductions, and health and safety issues related to human exposure. It is an important reference addressing the ongoing concern about the consequences of air pollution, and the implementation and modification of the Environmental Protection Agency's (EPA) Clean Air Act.
This book covers essential aspects of transmutation technologies, highlighting especially the advances in Japan. The accident at the Fukushima Daiichi Nuclear Power Plant (NPP) has caused us to focus attention on a large amount of spent nuclear fuels stored in NPPs. In addition, public anxiety regarding the treatment and disposal of high-level radioactive wastes that require long-term control is growing. The Japanese policy on the back-end of the nuclear fuel cycle is still unpredictable in the aftermath of the accident. Therefore, research and development for enhancing the safety of various processes involved in nuclear energy production are being actively pursued worldwide. In particular, nuclear transmutation technology has been drawing significant attention after the accident. This publication is timely with the following highlights: 1) Development of accelerator-driven systems (ADSs), which is a brand-new reactor concept for transmutation of highly radioactive wastes; 2) Nuclear reactor systems from the point of view of the nuclear fuel cycle. How to reduce nuclear wastes or how to treat them including the debris from TEPCO s Fukushima nuclear power stations is discussed; and 3) Environmental radioactivity, radioactive waste treatment and geological disposal policy. State-of-the-art technologies for overall back-end issues of the nuclear fuel cycle as well as the technologies of transmutation are presented here. The chapter authors are actively involved in the development of ADSs and transmutation-related technologies. The future of the back-end issues in Japan is very uncertain after the accident at the Fukushima Daiichi NPP and this book provides an opportunity for readers to consider the future direction of those issues."
Identifying efficient solutions to protect coastal regions from marine pollution requires expertise from a range of specialties and strategic approaches. This book gathers information on the impact of oil spills at a coastal level from different experts' points of view, identifying synergies between domains such as mathematics, numerical modeling, mechanics, biology, economics and law. The collaborative research presented here is based on the 4th International Workshop on Anti-Pollution and Marine Coastal Water Pollution, held in La Rochelle, France at the Engineering School EIGSI, in April 2012. The areas addressed include: materials and structures (fluid-structure and capture interaction, cable and membrane equations, optimization); coastal hydrodynamics (computational fluid dynamics, numerical analysis of shallow water equations, analytical and numerical derivatives); biological impacts (biology, multivariate analysis, indicators); and economics and law (compensation costs, insurance coverage, coastal vulnerability).

This study, originally published in 1972, examines the connections between human society and the rest of the universe that are attributable to economic activity. These include the inputs from the environment to industry, such as oxygen, used in the combustion of mineral fuels. Also included are the industrial outputs which are fed back into the environment in the form of waste products. An attempt will be made to establish functional relations between the extent and character of economic activity and the flow of materials in both directions between the economy and the environment. This title will be of interest to students of environmental and natural resource economics. |
