This book explores the work of transnational bureaucracy networks. These networks address global issues by creating rules - transnational public law - to be incorporated into national legal orders. As classical means fail to legitimize such activities, this book gives a practical account of viable alternative legitimacy mechanisms.
Presenting a new way to examine water quality criteria, this volume provides concise, critical reviews of timely advances in the field of xenobiotics. The text explores the research findings and procedures of The University of California-Davis Methodology for Deriving Aquatic Life Pesticide Water Quality Criteria.
Chemical additives are used to enhance the properties of many industrial products. Since their release into the environment is a potential risk for man and nature, their fate and behavior were investigated in the framework of the European Union-funded project RISKCYCLE. The results are presented in two volumes, "Global Risk-Based Management of Chemical Additives I: Production, Usage and Environmental Occurrence" and "Global Risk-Based Management of Chemical Additives II: Risk-Based Assessment and Management Strategies." This book is the first of the two volumes and contains two main parts. The chapters of the first part provide a thorough review of the chemical additives used in the textile, plastics, lubricants, paper, leather and electronics industries, and describe the effect of each additive on the properties of the product. In the second part international case studies on the global trade of these chemicals and their impact on human health and the environment are presented. This volume is an invaluable source of information for scientists and governmental agencies dealing with the risk assessment of chemicals on a global scale.
This book examines the role and practical dynamics of governmental environmental law enforcement agencies and individuals who combat environmental crime. It will inform researchers about the 'real world' experiences of practitioners and provide an intellectual space for practitioners to examine critically what it is they do and why.
Life on Earth is critically dependent upon the continuous cycling of water between oceans, continents and the atmosphere. Precipitation (including rain, snow, and hail) is the primary mechanism for transporting water from the atmosphere back to the Earth s surface. It is also the key physical process that links aspects of climate, weather, and the global hydrological cycle. Changes in precipitation regimes and the frequency of extreme weather events, such as floods, droughts, severe ice/snow storms, monsoon fluctuations and hurricanes are of great potential importance to life on the planet. One of the factors that could contribute to precipitation modification is aerosol pollution from various sources such as urban air pollution and biomass burning. Natural and anthropogenic changes in atmospheric aerosols might have important implications for precipitation by influencing the hydrological cycle, which in turn could feed back to climate changes. From an Earth Science perspective, a key question is how changes expected in climate will translate into changes in the hydrological cycle, and what trends may be expected in the future. We require a much better understanding and hence predictive capability of the moisture and energy storages and exchanges among the Earth s atmosphere, oceans, continents and biological systems. This book is a review of our knowledge of the relationship between aerosols and precipitation reaching the Earth's surface and it includes a list of recommendations that could help to advance our knowledge in this area."

The book gives theoretical knowledge and practical approaches on the complex process of water management in case of pollution with chemical and biological hazards. Frameworks addressing scientific and management strategies are included. Critical for successful prevention and control actions of accidental and intentional water pollution is the preliminary risk assessment, understanding of the hazards, and lessons learned from previous pollution events. Emphasis is given to biological hazards, which are as diverse as the list of chemical pollutants and represent groups belonging to algae, diatoms, bacteria, helminthes, parasites, and viruses. Chemicals and toxins are overviewed that may be used for intentional water pollution. Preventive and responsive driven strategies are addressed also to the agriculture as an important source for pesticide and fertilizer pollution...
Herbicides constitute about 60% of the total pesticides consumed globally. In India, the use of herbicides started initially in tea gardens and picked up in the 1970s, when the high-yielding varieties of rice and wheat were introduced. Presently, 67 herbicides are registered in the country for controlling weeds in crops including cereals, pulses, oilseeds, fibre and tuber crops, and also in the non-crop situations. These chemicals are becoming increasingly popular because of their efficiency and relatively low cost compared with manual or mechanical weeding operations. The contribution of herbicide to total pesticide use, which was only 10-15% during the first decade of the 21st century, has now increased to about 25% with an annual growth rate of 15-20%, which is much higher than insecticides and fungicides. Though the application of herbicides is minimizing yield loss to a great extent, their residues in the food chain and surface and groundwater create some environmental nuisance particularly to non-target organisms. Research on pesticide residues in India was started during 1970s, when such chemicals were introduced on a greater scale along with high-yielding variety seeds, irrigation and chemical fertilizers for increasing food production. However, the herbicide residue research was not given much emphasis until 1990s. The Indian Council of Agricultural Research initiated a national level programme known as All India Coordinated Research Project on Weed Management through the NRC-Weed Science as the main centre along with some centers of ICAR Institutes and state agricultural universities. Over the last two decades, adequate information was generated on estimation, degradation and mitigation of herbicide residues, which were documented in annual reports, bulletins, monographs and scientific articles. However, there was no consolidated compilation of all the available information providing a critical analysis of herbicide residues. Accordingly, an effort has been made in the publication to compile the available information on herbicide residues in India. This is the first report of its kind which presents the findings of herbicide residues and their interactions in the biotic and abiotic environment. There are 16 chapters contributed by the leading herbicide residue scientists, each describing the present status of herbicide use, crops and cropping systems, monitoring, degradation and mitigation, followed by conclusions and future lines of work. This book will be useful to the weed scientists in general and herbicide residue chemists in particular, besides the policy makers, students and all those concerned with the agricultural production in the country.
Based on micro-level empirical research, this book uniquely addresses the problem of arsenic contamination in ground water in Bangladesh in a comprehensive way. At the outset, the book puts forward the opinions of experts regarding the cause of arsenic contamination in ground water in Bangladesh, followed by sample surveys depicting socioeconomic and arsenic-related situations in three arsenic-affected villages in Meherpur district, Bangladesh. The major contribution of the author is the mixed-integer Pareto optimality model (tested and proved through computer simulation), developed in order to supply safe water to the badly affected people in Taranagar village. The model takes into account such issues as the costs of different safe water options, exposure to arsenic and bacteria, distance of the water source from home, indigenous cultural traits, environmental safety and acceptability of the options to the people. Besides successful development and application of the model, the book outlines ways to persuade people to change their habits regarding drinking tube-well water and proposes a system through which safe water can be supplied to Taranagar village. The book emphasizes socioeconomic, environmental and administrative aspects of selecting an optimal safe water option and ensuring consumption from safe water sources, which can be tested for other arsenic-affected areas as well. With relevant, attractive charts, tables, graphs, flowcharts and other graphics and with lucid language, the book makes rather difficult theoretical economics issues easily comprehensible and interesting to general readers, graduate and undergraduate students, researchers and NGO/GO workers who are dedicated to providing safe water to people affected by arsenic contamination.

Emission inventory is basic for the understanding of environmental behaviors and potential effects of compounds, however, current inventories are often associated with relatively high uncertainties. One important reason is the lack of emission factors (EFs), especially for the residential solid fuel combustion in developing countries. In the present study, emission factors of a group of pollutants including particulate matter, organic carbon, elemental carbon (sometimes known as black carbon) and polycyclic aromatic hydrocarbons were measured for a variety of residential solid fuels including coal, crop straw, wood, and biomass pellets in rural China. The study provided a large number of emission factors that can be further used in emission estimation. Composition profiles and isomer ratios were investigated and compared so as to be used in source apportionment. In addition, the present study identified and quantified the influence of factors like fuel moisture, volatile matter on emission performance. The publication of the study will be of interest and helpful to the readers in the field of air pollution, human health, fuel saving and energy consumption etc. Guofeng Shen works at the Institute of Atmospheric Sciences, Jiangsu Academy of Environmental Sciences, China.
Environmental pollutants have become a major global concern. The modern growth of industrialization, urbanization, modern agricultural development and energy generation have resulted in indiscriminate exploitation of natural resources for fulfilling the human desires and needs, which have contributed in disturbing the ecological balance on which the quality of environment depends. The modern technological advancements in chemical processes/operations have been raised to new products and also new pollutants in abundant level which are above the self cleaning capacity of the environment. One of the major issues in present times is the threat to human lives, due to the progressive deterioration of the environment. This book discusses bioremediation technology-based remediation to restore contaminated sites and protect the environment. It studies the opportunities for more efficient biological processes in molecular biology and ecology. Notable accomplishments of these studies include the cleaning up of polluted water and contaminated land. The book includes invited papers by eminent contributors who provide cost-effective bioremediation strategies to immobilize contaminants for cleanup of environment. The book is directed towards postgraduate students in biotechnology/life sciences/environmental sciences/biosciences and researchers in universities and research institutes and industries.

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.
A pollution haven may arise if environmental stringency differs between countries, when capital is mobile, and when trade rules allow firms to relocate and still sell their products to the same customers. This cohesive volume analyzes how country characteristics determine environmental rules, how those rules affect production costs, trade, and investment flows, how those flows affect pollution, prices, and incomes, and finally how all of these last considerations feed back into environmental rules. The sixteen papers collected here represent the most recent and significant advancements of knowledge on the subject. The contributors, all well-known scholars in the area, investigate how polluter location decisions respond to pollution policies, how local environmental rules respond to those location decisions, and how trade liberalization affects the incentives of governments to regulate dirty industries. The volume begins with a comprehensive overview by M. Scott Taylor and goes on to explore how the usual effects of pollution havens can be reversed. Also covered are the ways in which managed trade and trade liberalization, the regulation of multinationals, political stability and emissions controls impact pollution havens. Written for a multidisciplinary audience, The Economics of Pollution Havens will be of interest to those working in the areas of economics, international trade, political science, public policy, and environmental studies.

Virtually every city in the nation's older industrial regions, no matter its size, grapples with the challenge of unused or abandoned manufacturing facilities and other industrial sites. Local public officials, economic development practitioners, and site owners who have sought to revitalize fallow industrial properties face daunting challenges: contamination of the buildings, equipment, and surrounding land and water. Public concern about health effects from hazardous chemicals, changing environmental law, and evolving private sector development and financing priorities have made it increasingly difficult for communities to restore and reuse former manufacturing sites. This study, sponsored by the Northeast-Midwest Institute, offers analysis and practical guidance on how these blighted areas--brownfields--have been and can be brought back to life.
This volume originates from the NATO Advanced Study Institute Environmental UV Radiation: Impact on Ecosystems and Human Health and Predictive Models, held in Pisa, Italy in June 2001. The Institute was sponsored and mainly funded by the NATO Scientific Affairs Division, whose constant contribution in favour of the cooperation among scientists from different countries must be acknowledged. Other Institutions substantially contributed to the success of the ASI and our thanks and appreciation go to the Italian National Research Council (Consiglio Nazionale delle Ricerche), the Italian Space Agency (Agenzia Spaziale Italiana), the European Society for Photobiology and the bank Banca Toscana. In the last two decades of the past century, concern has been growing for the possible effects on the biosphere of the stratospheric ozone depletion, due to anthropogenic emissions of ozone-destroying chemicals. The ozone loss causes an increase in the biologically important part of the solar ultraviolet radiation (UV) reaching the Earth's surface, which constitutes a threat to the biosphere, because of UV damaging effects on humans, animals and plants. The international agreements have reduced the production of ozo- destroying compounds, which, however, are still present in high concentrations in the stratosphere, mainly because of their longevity, and thus ozone depletion will likely continue for several decades.
In this day and age, it is unfortunate that the economic prosperity and development leads to disruption of the dynamic balance of the environment. The philosophy of sustainable development has been presented for a long period of time but it has not been able to bring about a substantial change in our society. The transformation of this philosophy into a practical reality seems to be far away - at least in the foreseeable future. In my opinion, the only way I see the revolution taking place is for us to incorporate 'sustainability' in our daily living and to keep pushing for a sustainable society. Meanwhile, we also need scientists to work on technologies that would lead us to that goal at a faster pace. Technologies that are 'completely' environmentally friendly are needed urgently. And if such technologies or ideas of one exists, a platform is required that showcases such ideas to the scientific and non-scientific audience. Through this book, I am happy to present the thoughts of seven different research groups whose work may lead us to the doorsteps of sustainable society. As scientists, most of us specialize in a sub-topic that may be related to one of the three environmental components - air, land, or water. Over a period of time, we become so engrossed with the sub-discipline of our specialization that we only have glimpses of what is happening in other disciplines.
In this book, Tingsong Jiang extensively discusses the wider issues of economic instruments of pollution control as well as paying specific attention to the control of carbon dioxide emissions in China. The book begins with a general analysis of economic instruments of pollution control, and is followed by the application of these in CO2 emission control. The former presents the discussion of pollution control policies in general equilibrium settings, focusing on the comparison of pollution taxes and tradable permits in certain kinds of circumstances with imperfections such as uncertainty and pre-existing distortions. An empirical evaluation of China's environmental policies is also included. The latter brings the discussion into the area of global warming policies with the focus on the implications to China. A dynamic general equilibrium model, G-Cubed-T, is developed to produce CO2 emissions projections from China, the US and the rest of the world, and to simulate various policy targets and instruments China may adopt to control its CO2 emissions. With its systematic evaluation of China's environmental policy, this thorough and rigorous assessment will be invaluable reading for academics in environmental economics and environmental management, policy analysts in environmental protection and global warming fields, policymakers and government officials around the world, as well as China specialists.
Due to their unparalleled effectiveness and efficiency, polyfluorinated chemicals (PFC") "have become essential in numerous technical applications. However, many PFCs brought to market show limited biodegradability, and their environmental persistence combined with toxic and bioaccumulative potential have become a matter of concern in some instances. This volume highlights the synthesis of PFCs, focusing on substances with improved application and environmental properties, which are a challenge for synthetic chemists. Further, modern mass spectrometric techniques for the detection and identification of biotransformation products of PFCs are described. The sorption and leaching behavior of PFC in soil is also addressed in order to predict their fate in the environment. Several contributions discuss the monitoring of PFCs in European surface, ground and drinking waters, treatment options for PFC removal from drinking water, occurrence in food, and the human biomonitoring of PFCs. |
