Evaluation Of Environmental Data For Regulatory And Impact Assessment from the Author: S. Ramamoorthy. Mounting concern for the state of the environment has led to a substantial increase in the collection of environmental data in the past two decades. This trend raises issues with regard to the quality assurance and quality control of the data gathering process, from sampling to analysis. The evaluation of environmental data in terms of quality, and relevance for use in the management of toxic chemicals in the enviroment, has reached a critical phase. An enormous volume of data is being generated, on both residue levels and their effects, to meet short- and long-term needs for regulatory procedures and (environmental) impact assessments. Therefore, it is important to verify not only the quality of the data collected, but also the choice of relevant test parameters. This volume deals with the evolution of analytical methodologies to the current state-of-the-art techniques, quality assurance/quality control of data acquirements, and testing procedures for screening of toxic chemicals - including their hazard identification, persistence, and fate processes in the environment. The models currently employed in environmental impact assessment and risk assessment are also discussed in detail. Public involvement and participation in regulatory decision-making processess is also described. It is intended for managers and scientists involved in environmental management and research of toxic chemicals in the environment.

Biophysico Chemical Processes Of Anthropogenic Organic Compounds In Environmental Systems from the Author: Baoshan Xing. In contrast to the classical books which largely focus on separate, individual physicochemical and biological aspects, this book aims to integrate the frontiers of knowledge on the fundamentals and the impact of physicochemical and biological interactions and processes of AOCs in soil, sediment, water and air. The specific objectives of this book are to address: (1) fundamental biophysico-chemical processes of AOCs in the environment, (2) occurrence and distribution of AOCs in air, water, and soil, and their global cycling, (3) the state-of-the-art analytical techniques of AOCs, and (4) restoration of natural environments contaminated by AOCs. The book also identifies the gaps in knowledge on the subject matter and as such provides future directions to stimulate scientific research to advance the chemical science on biophysico-chemical interfacial reactions in natural habitats. By virtue of complex nature of the interactions of AOCs with different environmental components and matrixes, no single available technique and instrument is satisfactory yet for determining their fate, transport, availability, and risk in the environment. In order to fully understand the biophysico-chemical interactions and processes of AOCs in the environment, it is critical to know chemical, physical and biological properties of AOCs and their analytical techniques. The book is unique because of its multidisciplinary approach as it provides a comprehensive and integrated coverage of biophysico-chemical reactions and processes of AOCs in various environments, associated analytical techniques, and restoration of natural environments contaminated by AOCs.

Colloids In The Aquatic Environment from the Author: Th. F. Tadros. Colloids in the Aquatic Environment covers the proceedings of the International Symposium by the same title, held at the University College London on September 7-9, 1992, organized by the SCI Colloid and Surface Chemistry Group. This book is divided into 20 chapters and begins with an introduction to the fundamentals of surface structure and reactivity. The succeeding chapters deal with molecular mass determination of humic substances from natural waters, the biospecific mechanism of double layer formation, the dynamics of colloid deposition in porous media, and the evaluation of surface area and size distributions of soil particles. These topics are followed by discussions of the transport and capture of colloids; colloidal stability of natural organic matter; the hydrolytic precipitation and modeling ion binding by humic acids; and the thermodynamic aspects and photoelectrophoresis of colloids. Other chapters explore the colloidal transfer in several aquatic environments. The final chapters consider the mechanism of colloid detachment, speciation, partitioning, and stability. These chapters also look into a hybrid equilibrium model of solute transport in porous media in the presence of colloids. This book will be of great value to civil and environmental engineers.

Air Pollution Modeling And Its Application X from the Author: Sven-Erik Gryning. The 20th International Technical Meeting on Air Pollution Modelling and Its Application was held in Valencia, Spain, during late 1993. At this conference, a new record of abstracts was submitted, a new record of scientists participated, and a new record of countries was represented. This clearly indicates society's continuous and growing interest in, as well as importance of, the complexities associated with the modelling of air pollution. The conference addressed the following main subjects: integrated regional modelling, global and long-range transport, new modelling developments, accidental releases, and model assess ment and verification. In addition, two project-oriented workshops were organized as part of the conference. The many contributing authors and scientists taking active part in the discussions following the papers, have made this proceeding a record of the current status in the field of air pollu tion modelling. We want to express our gratitude to their efforts. We also wish to extend our gratitude to the sponsors that made this conference possible. In addition to financial support from NATOjCCMS the conference received contributions from CEAM, the European Asso ciation for the Science of Air Pollution, Danish Center for Air Research, and Ris0 National Laboratory. A special grant was given by NATOjCCMS to facilitate attendance of scientists from Central and Eastern Europe. We also wish to express our gratitude to Rosa Salvador and Pilar Zamora of CEAM, who laboriously organized the conference pre-proceedings, and to Anne N0rregaard and Ulla Riis Christiansen of Ris0 National Laboratory, who seved as conference secretariat.

Environmental Chemistry Ninth Edition from the Author: Stanley Manahan. The field of environmental chemistry has evolved significantly since the publication of the first edition of Environmental Chemistry. Throughout the book’s long life, it has chronicled emerging issues such as organochloride pesticides, detergent phosphates, stratospheric ozone depletion, the banning of chlorofluorocarbons, and greenhouse warming. During this time the first Nobel Prize for environmental chemistry was awarded. Written by environmental chemist Stanley Manahan, each edition has reflected the field’s shift of emphasis from pollution and its effects to its current emphasis on sustainability. What makes this book so enduring? Completely revised, this ninth edition retains the organizational structure that has made past editions so popular with students and professors while updating coverage of principles, tools, and techniques to provide fundamental understanding of environmental chemistry and its applications. It includes end-of chapter questions and problems, and a solutions manual is available upon qualifying course adoptions. Rather than immediately discussing specific environmental problems, Manahan systematically develops the concept of environmental chemistry so that when he covers specific pollutions problems the background necessary to understand the problem has already been developed. New in the Ninth Edition: revised discussion of sustainability and environmental science updates information on chemical fate and transport, cycles of matter examination of the connection between environmental chemistry and green chemistry coverage of transgenic crops the role of energy in sustainability potential use of toxic substances in terrorist attacks Manahan emphasizes the importance of the anthrosphere – that part of the environment made and operated by humans and their technologies. Acknowledging technology will be used to support humankind on the planet, it is important that the anthrosphere be designed and operated in a manner that is compatible with sustainability and that it interacts constructively with the other environmental spheres. With clear explanations, real-world examples, and updated questions and answers, the book emphases the concepts essential to the practice of environmental science, technology, and chemistry while introducing the newest innovations in the field. Readily adapted for classroom use, a solutions manual is available with qualifying course adoption.

Metabolism Of Polycyclic Aromatic Hydrocarbons In The Aquatic Environment from the Author: Usha Varanasi. This book shows how the biological transport, bioaccumulation, disposition, and toxicity of polycyclic aromatic hydrocarbons (PAH) in the aquatic environment are influenced by the ability or inability of organisms to metabolize these environmental pollutants. Written by leading scientists in the fields of PAH metabolism and toxicity in both aquatic and mammalian systems, this book discusses recent advances in the areas of PAH biogeochemistry and bioaccumulation, microbial degradation, enzymes of activation, and detoxication, metabolism of PAH, and laboratory and field studies on carcinogenic/toxic effects. Additionally, important similarities and differences in metabolism of PAH by aquatic and terrestrial organisms are featured. The discussion of bioavailability, metabolism, and subsequent toxic effects should aid in the assessment of the ecological consequences of PAH in the aquatic environment.
