This book summarizes recent progress in cellulose chemistry. The last 10 years have witnessed important developments, because sustainability is a major concern. Biodegradable cellulose derivatives, in particular esters and ethers, are employed on a large scale. The recent developments in cellulose chemistry include unconventional methods for the synthesis of derivatives, introduction of novel solvents, e.g. ionic liquids, novel approaches to regioselective derivatization of cellulose, preparation of nano-particles and nano-composites for specific applications. These new developments are discussed comprehensively. This book is aimed at researchers and professionals working on cellulose and its derivatives. It fills an important gap in teaching, because most organic chemistry textbooks concentrate on the relatively simple chemistry of mono- and disaccharides. The chemistry and, more importantly, the applications of cellulose are only concisely mentioned.

The aim of this book is to present an overview of the state of the art with regard to the function, application and design of TWSs in order to better protect surface water from contamination. Accordingly, it also presents applications of constructed wetlands with regard to climatic and cultural aspects. The use of artificial and natural treatment wetland systems (TWSs) for wastewater treatment is an approach that has been developed over the last thirty years. Europe is currently home to roughly 10,000 constructed wetland treatment systems (CWTSs), which simulate the aquatic habitat conditions of natural marsh ecosystems; roughly 3,500 systems are in operation in Germany alone. TWSs can also be found in many other European countries, for example 200 - 400 in Denmark, 400 - 600 in Great Britain, and ca. 1,000 in Poland. Most of the existing systems serve as local or individual household treatment systems. CWTSs are easy to operate and do not require specialized maintenance; further, no biological sewage sludge is formed during treatment processes. As TWSs are resistant to fluctuations in hydraulic loads, they are primarily used in rural areas as well as in urbanized areas with dispersed habitats, where conventional sewer systems and central conventional wastewater treatment plants (WWTPs) cannot be applied due to the high costs they would entail. TWSs are usually applied at the 2nd stage of domestic wastewater treatment, after mechanical treatment, and/or at the 3rd stage of treatment in order to ensure purification of effluent from conventional biological reactors and re-naturalization. New applications of TWSs include rainwater treatment as well as industrial and landfill leachate treatment. TWSs are well suited to these fields, as they can potentially remove not only organic matter and nitrogen compounds but also trace metals and traces of persistent organic pollutants and pathogens. Based on the practical experience gathered to date, and on new research regarding the processes and mechanisms of pollutant removal and advances in the systems properties and design, TWSs continue to evolve.
The protection of the environment is one of the most important problems facing us today. Reliable and robust strategies for keeping pollution caused by harmful chemicals under safe levels have to be developed and used routinely. Large mathematical models, incorporating all important physical and chemical processes, can solve this task, but the computational burden is huge. The papers presented here describe some of the difficult problems that have to be solved during the development of large scale air pollution models, and different ways to solve them. The work involves combined research by specialists in the fields of environmental modelling, numerical analysis and scientific computing. Further, if models are to run in real time (which may be vital in the case of accidental hazardous releases), then new and efficient methods that harness the potential power of parallel supercomputers must be developed, so that actual computing speed starts to approach the maximum available performance. The articles should be understandable by specialists in the field of air pollution modelling, as well as specialists in the many other related areas.
Focusing on the problems of pollution reduction and containment, this book discusses various waste management practices that have resulted from increasingly stringent government regulations. Several chapters deal with the practical applications of pollution and contaminant control technology to specific industries, including printing, semi-conductor manufacturing, leather tanning, aluminum smelting and wood preserving Techniques for site remediation, treatment of wastewater, management of underground and storage tanks, asbestos abatement, waste treatment for petroleum and synthetic fuel and incineration of medical wastes are also covered.
This book highlights various aspects of shale gas production and discusses the associated problems, which have greatly influenced the current situation on the global gas market. It focuses on issues such as production technologies, environmental protection, and the impacts of shale gas production on human beings. Further, it investigates the role of shale gas in the development and implementation of foreign policy of many nations that welcomed the possibility to produce this hydrocarbon in their own countries. Taking into consideration the information published by world energy research centers, the prospects of shale gas production in different regions of the world are examined in detail. Given its coverage and scope, the book will greatly benefit specialists in the areas of hydrocarbon production, international relations and foreign policy, world economics and technologies, ecology and environmental protection.
The book summarizes the knowledge and experiences concerning the role of halogens during various geochemical processes, such as diagenesis, ore-formation, magma evolution, metasomatism, mineralization, and metamorphism in the crust and mantle of the Earth. It comprises the role of halogens in other terrestrial worlds like volatile-rich asteroids, Mars, and the ice moons of Jupiter and Saturn. Review chapters outline and expand upon the basis of our current understanding regarding how halogens contribute to the geochemical/geophysical evolution and stability of terrestrial worlds overall.
Written by an award-winning historian of science and technology, Planet in Peril describes the top four mega-dangers facing humankind - climate change, nukes, pandemics, and artificial intelligence. It outlines the solutions that have been tried, and analyzes why they have thus far fallen short. These four existential dangers present a special kind of challenge that urgently requires planet-level responses, yet today's international institutions have so far failed to meet this need. The book lays out a realistic pathway for gradually modifying the United Nations over the coming century so that it can become more effective at coordinating global solutions to humanity's problems. Neither optimistic nor pessimistic, but pragmatic and constructive, the book explores how to move past ideological polarization and global political fragmentation. Unafraid to take intellectual risks, Planet in Peril sketches a plausible roadmap toward a safer, more democratic future for us all.
This book presents the reader with a story-based narrative of discovery and development of radiation-induced graft polymerization. The report presented here accomplishes this by relating the inspiring account of research and development based on long-term collaboration among a professor, an engineer, and an entrepreneur. Their goal, ultimately successful, was to come up with a method for grafting functional polymer chains onto existing trunk polymers. The desired outcome was to produce feasible forms for practical use as adsorbents such as porous hollow-fiber membranes, porous sheets, nonwoven fabrics, and fibers. Adsorbents that specifically and efficiently bind to target ions and molecules are essential for capturing uranium species in seawater and antibody drugs in biological fluids and for removing metal ions from ultrapure water and radioactive cesium ions from contaminated water. This unique volume, with its clearly written text and many illustrative figures and diagrams, demonstrates the advantages of the high-adsorption capacity and rate and the easy handling of new polymeric adsorbents over conventional adsorbents. The dynamic behavior of graft chains as described here is certain to appeal especially to chemists, physicists, and material scientists as well as to other readers with an interest in this valuable subject.

This thesis presents a comprehensive analysis of the global health impacts of polycyclic aromatic hydrocarbons (PAHs) in ambient air, conducted on the basis of a high-resolution emission inventory, global chemical transport modeling, and probabilistic risk assessment. One of the main strengths of the thesis is the concentration downscaling process, which provides a linkage between emissions and exposure concentrations at a comparatively high resolution. Moreover, by focusing on individual susceptibility, the thesis proposes an instrumental revision of current risk assessment methodology and argues that, if individual susceptibility were not taken into consideration, the overall risk would be underestimated by 55% and the proportion of highly vulnerable populations would be underestimated by more than 90%.
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
Forest ecosystems are characterized by a steady change in their structure of function. Natural developments are more and more radically disturbed by human impact. Air pollution leads to soil acidification, change in nutrient budget and to a decreasing vitality of the trees. Forest management can prevent natural succession and often leads to less stable forests. In this book, selected results of 10 years of interdisciplinary ecosystem research are presented. Not only growth and physiological reactions on environmental stress, but also natural succession processes are described and analysed. Besides the description of forest development processes, based on longterm experiments and observation, conclusions for practical forest management are given.
Green Criminology has the potential to provide not only a different way of examining and making sense of various forms of crime and control responses, but can also make explicable much wider connections which are not generally well understood. As all societies face up to the need to confront harms against the environment, other animals and humanity, criminology will have a major role to play. This book will be an essential part of this process. This edited collection brings together internationally renowned scholars to explore green criminology through the interdisciplinary lenses of power, justice and harm. The chapters provide innovative case study analyses from North America, Europe and Australia that seek to advance theoretical, policy and practice discourses about environmental harm. The book unifies transnational debates in environmental law, policy and justice, and in doing so examines international agreements and policy within diverse environmental discourses of sociology, criminology and political economy. Emerging Issues in Green Criminology is an essential source for students, scholars and policy makers in this rapidly growing area of criminology, as well as environmental studies more broadly. The international range of contributors include Lieselot Bisschop (University College Ghent, Belgium), Avi Brisman (Eastern Kentucky University, USA), Matthew Hall (University of Sheffield, UK), M.H.A Kluin (Delft University of Technology, the Netherlands), Olga Knight (University of Colorado, Denver, USA), Peter Martin (Queensland University of Technology, Australia), Hanneke Mol (University of Kent, UK and Utrecht University, Netherlands), Angus Nurse (Birmingham City University, UK), Ragnhild Sollund (University of Oslo, Norway), Nigel South (University of Essex, UK), Paul B. Stretesky (University of Colorado, Denver, USA), Gudrun Vande Walle (University College Ghent, Belgium) and Rob White (University of Tasmania, Australia).
The brave new world of environmental economics--complete with pollution markets, emission brokers, and commodity auctions of emission allowances--has been developing in the U.S. for several decades. This book traces the evolution of such environmental management techniques in industrial Philadelphia. Initially as a greene country towne, the city's development led to significant pollution concerns, including rivers filled with sewage, typhoid deaths, and smoky plumes from coal combustion. Technological pollution controls improved conditions, but blunt regulatory tools eventually evolved into more refined economic approaches. This book describes that transition and the economic mechanisms that have emerged in recent decades, as well as prospective markets for ozone precursors, greenhouse gas emissions, and environmental risk (potentially offering what one pundit labeled cancer futures). In doing so, it presents a comprehensive overview--from old to new--of urban environmental management.
A vivid rendering of the educational, social, and physical environment of two elementary schools in contrasting socioeconomic settings, this book calls attention to the importance of place in human lives and learning. The author draws from systematic observations conducted over a three-year period, presenting the schools and the persons who inhabit them via a fictionalized narrative. This treatment allows readers to understand how the material conditions of poverty and wealth inform children's worldview without compromising the identity of the study participants. Written by an eminent African-American professor of architecture and urban planning who is an outspoken advocate for social justice, this book is a rare gem.
The book presents the state-of-the-art document describing the knowledge, data, cost-effectiveness and technologies employed to manage the waste in several countries such as Morocco, Tunisia, Egypt, Jordon, Syria, Palestine, Lebanon, and Yemen. It covers diverse topics including the status of the waste in the region, solid waste management, solid waste recovery and disposal, the use of the agricultural waste in feeding poultry, sludge disposal and management, wastewater treatment and energy production. Also, the book explains how waste management systems are becoming more complex in many countries with the move from landfill-based to resource recovery-based solutions following the setting of international and national targets to divert waste from landfill and to increase recycling and recovery rates. Besides, this book also evaluates the environmental legislation in the selected countries and suggests new performance enhancements. This book is of interest to environmental professionals including scientists and policymakers in the Middle East, North Africa, and areas with similar features.
This volume examines crimes that violate environmental regulations, as part of an emerging area of criminology known as green criminology. The contributions to this book examine criminal justice concerns related to regulating and enforcing environmental laws, as well as the consequences for families and communities impacted by hazardous waste and pollution. It also describes possible strategies for deterring and preventing organized crime related to environmental regulations, including black market sales of ozone depleting substances. This innovative volume provides a criminological framework for understanding environmental harms. Examining cases from the US, Europe and Australia, this volume compares and contrasts international approaches for regulating hazardous substances, and enforcing those regulations. This work will be of interest to researchers in criminology and criminal justice, particularly interested in green criminology or environmental law, as well as researchers in environmental sciences, white collar and corporate crime, and policymakers.
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.
This monograph describes ways of using trees and their byproducts in environmental protection technologies and methodologies throughout their lifecycles. The tree, the planet's main source of biomass, is an indispensable tool for sustainable technologies, and the authors present a holistic picture of how and why in this volume. The authors describe the indispensable role of the living tree in phytoremediation and biomonitoring and detail the relationship of the tree with its surrounding ecosystem. The direct and indirect relationships of a tree at its vegetation period with various components of the ecosystem (i.e. atmosphere, hydrosphere, lithosphere and soil) contribute to the role of a tree as the medium for integrating aerogenic and edaphic pollutants. Trees phytostabilize pollutants in their organisms and remove them from the soil. The ability of some species of trees to reflect the quality of the environment makes a basis for the environmental bioindication, while quantitative representation of the chemical composition of the surrounding environment allows for the use of trees in biomonitoring. Morphological features of trees (e.g. annual tree rings) allow us to observe environmental conditions in the past and retrospectively evaluate them. This monograph also details how wood products (e.g. biochar, chips, bark, etc.) of a tree after it has died are used in environmental technologies. Due to the specific morphological form and physical and chemical composition of wood products, they may be used as active materials in the technologies aimed at reducing pollution in an effective and sustainable manner.
This volume offers an overview of the occurrence of emerging organic contaminants in Mediterranean rivers and their relevance to their chemical and ecological quality under water scarcity. With chapters covering the effects under multiple stress conditions of pharmaceuticals, polar pesticides, personal care products, and industrial chemicals, the observations presented can be applicable to other parts of the world where water scarcity is an issue . It is of interest to environmental chemists, ecologists, environmental engineers, and ecotoxicologists, as well as water managers and decision-makers.
The socio-economic activities due to world development are promoting increasing pressures on land, creating competition and conflicts, resulting in suboptimal use of resources. Integrated planning and management of land resources is a top subject of Agenda 21 (managed by FAO), which deals with the cross-sectoral aspects of decision-making for the sustainable use and development of natural resources. This is essential for life-support systems and its productive capacity. In this context, there is a need to find new strategies for sustainable development that links social and economic progress with environmental protection and enhancement. Electrokinetic transport processes (EK) uses a low-level direct current as the "cleaning agent". EK has been applied to the remediation of polluted soils and other contaminated matrices. It also shows a great potential to be used in different fields, as in saline soil restoration, nutrients recovery from wastes or repair and maintenance of building structures. EK may be an integrated approach for new strategies aiming at sustainable development and to support waste strategies, with worldwide interest. EK can also be coupled with phytoremediation and integrated with nanotechnology, enlarging the scope of its application. The conciliation of the EK in the recovery of secondary resources, remediation and conservation is a multidisciplinary novel approach that opens new technical possibilities for waste minimization, through upgrading of particulate waste products and the recovery of secondary resources for industrial, agricultural or social use. |
