Human exposure to toxic substances that cause cancer, reproductive abnormalities, and other adverse health effects is a topic of increasing interest to scientists, journalists, workers, business executives, advocacy groups, and the public at large. Citizen concern has prompted the government to establish an elaborate regulatory system designed to protect people from chemical exposures. Harnessing Science examines the role of science in toxic chemical regulation at the U.S. Environmental Protection Agency. The book postulates that scientific knowledge and advice from experts outside of government is critical to the competence and credibility of regulations designed to protect public health.

This unique volume takes a close look at the contributions of three specific organizations that were designed to improve regulatory science: the Chemical Industry Institute of Toxicology (CIIT), the Science Advisory Board of the EPA, and the Health Effects Institute. Early chapters trace the origins and histories of each of these three organizations. Then regulatory case studies of selected chemical substances (unleaded gasoline, perchloroethylene, formaldehyde, nitrates, and carbon monoxide) are used to assess the contributions of CIIT, SAB, and HEI. The final chapter makes specific recommendations designed to strengthen these organizations. Harnessing Science for Environmental Regulation is essential reading for anyone who is interested in how science influences regulatory decisions about human exposure to toxic chemicals. It will be of special interest to federal and state policy makers, practicing scientists, environmental advocates, risk assessors, corporate managers, and environmental journalists.

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 have been 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 second of the two volumes and features two main parts. In the first part, experts in the field discuss different models related to the assessment of the potential risks posed by chemical additives and analyze their benefits and drawbacks. In the second part, specific case studies in which the models have been applied are presented and the reliability of the models is evaluated. This volume is an invaluable source of information for scientists and governmental agencies dealing with the risk assessment of chemicals on a global scale.

Wind erosion occurs in many arid, semiarid and agricultural areas of the world. It is an environmental process in?uenced by geological and climatic variations as well as human activities. In general, wind erosion leads to land degradation in agricultural areas and has a negative impact on air quality. Dustemissiongeneratedbywinderosionisthelargestsourceofaerosolswhich directly or indirectly in?uence the atmospheric radiation balance and hence global climatic variations. Strong wind-erosion events, such as severe dust storms, may threaten human lives and cause substantial economic damage. The physics of wind erosion is complex, as it involves atmospheric, soil and land-surface processes. The research on wind erosion is multidisciplinary, covering meteorology, ?uid dynamics, soil physics, colloidal science, surface soil hydrology, ecology, etc. Several excellent books have already been written about the topic, for instance, by Bagnold (1941, The Physics of Blown Sand and Desert Dunes), Greeley and Iversen (1985, Wind as a Geological P- cess on Earth, Mars, Venus and Titan), Pye (1987, Aeolian Dust and Dust Deposits), Pye and Tsoar (1990, Aeolian Sand and Sand Dunes). However, considerable progress has been made in wind-erosion research in recent years and there is a need to systematically document this progress in a new book.

The goal of the book is to examine scientific advances since 2000 that may have increased understanding and options in three general areas related to hypoxia:

As classical means fail to legitimize such activities, this book gives a practical account of viable alternative legitimacy mechanisms.

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...

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."

This book examines air pollution of a big city using multi-year and multi-season data from ground-based air monitoring stations and satellite sounding data, which provides more clear and detailed information on the main sources of air pollution, the long-term trend of pollution, the influence of meteorological parameters on pollution levels, and trajectories of polluted air masses. For example, the book shows that particulate matter from local sources is transported from deserts to create air quality challenges. It also analyzes the effects of desert and semi-desert landscapes on high concentrations of pollutants.

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.

It presents the principal characteristic features of the environmental conditions of the sea and their changes in the second half of the 20th century.

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.

Up-to-date coverage and a unique, multidisciplinary approach

The ongoing effort to protect our valuable ground-water resources necessarily involves scientists and engineers from many disciplines. Ground-Water Microbiology and Geochemistry, Second Edition is designed to bridge the historical lack of communication among these disciplines by detailing–in language that cuts across specialties–the impact of microorganisms and microbial processes on ground-water systems.

Carefully revised to reflect the many recent discoveries that have been made in the field, the Second Edition begins with an overview of microbiology, ideal for hydrologists and others who may lack formal training in the field. These initial chapters systematically cover the kinds of microorganisms found in subsurface environments, focusing on their growth, metabolism, genetics, and ecology.

The second part of the book offers a hydrologic perspective on how microbial processes affect ground-water geochemistry in pristine systems. It also introduces the different classes of ground-water systems, and gives an overview of techniques for sampling subsurface environments. Readers gain an understanding of biogeochemical cycling in ground-water systems–in coverage unique to this book–and how ground-water chemistry can be used to study microbial processes in aquifer systems.

The final section of the book deals with the biodegradation of human-introduced contaminants in ground-water systems, with an up-to-date review of the physiology, biochemistry, and redox conditions that favor biodegradation processes.

Ground-Water Microbiology and Geochemistry, Second Edition is important reading for geoscientists, hydrologists, and environmental engineers, as well as for water planners and lawyers involved in environmental issues. It also serves as a compelling text for upper-level undergraduate and graduate courses in ground-water chemistry.

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.

This book is the collection of papers from the latest International Uranium Mining and Hydrogeology Conference (UMH VII) held in September 2014, in Freiberg, Germany. It is divided to five sessions: Uranium Mining, Uranium and Phosphates, Clean-up technologies for water and soil. Uranium and daughter nuclides and basic research and modeling. Each session covers a wide range of related topic and provides readers with up to date research and solutions on those matters.

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.

This book is the second edited compilation of selected, refereed papers submitted to ERTEP 2007. The book is organized into 10 chapters along four of the key themes that were discussed at the conference: Environmental Health Management; Mining and Environment; Environmental Monitoring and Policy Development; and Susta- ability and Social Responsibility. It is hoped that the contents of the book will p- vide an insight into some of the environmental and health management challenges confronting the developing world and the steps being taken to address them. The ?rst three chapters under the Environmental Health and Management theme discusses issues related to food security and related environmental distress in sub- Saharan Africa. Chapter 1 argues that pervasive poverty and low agricultural p- ductivity are important factors in understanding food insecurity in the region, and broader global processes are examined. This chapter maintains that while poverty undermines individual and household access to suf?cient food through market p- chase, land inequalities, corruption, structural adjustment programs, civil con?ict, HIV/AIDS and the role of the World Trade Organization Agreement on Agric- ture are decisive. The authors argue that achieving food security in sub-Saharan Africa requires policies and actions that are integrated with efforts to reduce poverty, enhance livelihoods and incomes and increase agricultural output, while also paying attention to underlying structural factors that bear on agriculture in the region.
