Book excerpt: AQUATOX: Modelling Environmental Risk and Damage Assessment, a new volume in the Developments in Environmental Modelling series, provides a single source for all AQUATOX applications, including basic equations, applications and examples on model implementation in various aquatic habitats (riverine, lacustrine and estuarine). The book presents a comprehensive reference source for AQUATOX model applications that can be used for an ecological modeling course at the graduate level. Throughout the text, chapter headings are organized to help users understand model building processes, state variables, and components. Case studies are provided to enhance learning and help readers assemble and calibrate their own AQUATOX applications. Includes a detailed description of AQUATOX equations for researchers and practitioners (including regulatory agencies) Presents study files, descriptions of implementation, and the data used as a starting point for new study applications Explores case studies of various sample applications and how specific problems are approached, including eutrophication issues in lakes and streams and natural resource damages in Estuarine Areas

This book was released on 1982 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: THIS BOOK IS A RESULT OF THE FOURTH PELLSTON ENVIRONMENTAL WORKSHOP, HELD AUGUST 16-21, 1981. THIS WORKSHOP AND PREVIOUS MEETINGS HAVE EXAMINED METHODS OF ASSESSING HAZARDS OF CHEMICALS IN THE AQUATIC ENVIRONMENT. HAZARD ASSESSMENT, IT HAS BEEN DETERMINED, REQUIRES AN UNDERSTANDING OF THE RELATIONSHIP BETWEEN THE CONCENTRATION OF CHEMICALS CAUSING AN ADVERSE EFFECT ON AQUATIC LIFE AND ENVIRONMENTAL EXPOSURE CONCENTRATIONS. MATHEMATICAL ENVIRONMENTAL FATE MODELS ARE SUGGESTED AS A TOOL FOR PREDICTING ENVIRONMENTAL EXPOSURE CONCENTRATIONS OF CHEMICALS. THIS BOOK PRESENTS A STATE OF THE ART OVERVIEW OF THE USE OF THESE MODELS FOR DECISION MAKERS IN ASSESSING THE HAZARDS OF CHEMICALS IN THE AQUATIC ENVIRONMENT. AUTHORS SUMMARY ABRIDGED.

Available in PDF, EPUB and Kindle. Book excerpt: The capability to predict the environmental fate of chemicals based on their chemical properties is well developed and widely practiced. Poorly developed, however, is the capability to predict the effects of those chemicals. To address this deficiency, significant effort has been directed to the creation of mathematical models to predict the effects of toxicants in aquatic systems. These models consist of two parts: an ecological component and a toxicological component. The ecological components are organized at levels of integration and resolution intended to be relevant to the kinds of expected problems and questions to be addressed in determining whether to permit or prohibit the use of a new chemical. Models of systems in which the organisms are assumed to have reached steady state with respect to the level of toxicant are at the coarsest level of resolution. Populations are represented at an intermediate and ecosystems at a fine scale of resolution. A toxicological model in corresponding detail is associated with each level to provide predictions of effects. This model assumes for all levels that a common threshold concentration exists at which the organism dies. With this assumption, a model for exchange with the environment and assumptions of rapid internal distribution of the toxicant, the time to death for an individual depends on the fraction of its body comprised of fat. Probability of death by the end of a fixed exposure time is a function of the statistical distribution of the fraction of fat in the organisms' bodies.

This book was released on 2013-10-22 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling the Fate and Effect of the Toxic Substances in the Environment contains the proceedings of a Symposium on "Modeling the Fate and Effect of Toxic Substances in the Environment", held on June 6-10, 1983 in Copenhagen, Denmark, and sponsored by the International Society for Ecological Modeling. The symposium provided a forum for discussing the state of the art in modeling the fate and effect of toxic substances in the environment. Topics include parameter estimation, theoretical considerations, and models of a wide variety of toxic compounds in aquatic and terrestrial ecosystems. Comprised of 16 chapters, this volume begins with an account of parameter estimation in toxic substance models, followed by a discussion on extinction and persistence in models of population-toxicant interactions. The reader is then introduced to PATHWAY, a simulation model of the transport of radionuclides through agroecosystems. Subsequent chapters focus on possible cause-effect relationships in the dying of Germany's spruce-fir forests; application of risk and uncertainty analysis techniques to a heavy metal speciation model; the biological effects of toxicants in aquatic microcosm systems; and the dispersal and biological effect of toxins in the Tamar estuary in England. The book concludes with a description of a nonlinear mathematical model for the transport and spreading of oil slicks. This book will be useful to students, practitioners, and researchers in the field of inorganic chemistry, as well as those who are interested in the environmental effects of toxic compounds.

Download or read book Ecotoxicology Modeling written by James Devillers and published by Springer Science & Business Media. This book was released on 2009-08-07 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology Modeling is a comprehensive and well-documented text providing a collection of computational methods to the ecotoxicologists primarily interested in the study of the adverse effects of chemicals, their mechanisms of action and/or their environmental fate and behavior. Avoiding mathematical jargon, the book presents numerous case studies to enable the reader to understand the interest but also the limitations of linear and nonlinear models in ecotoxicology. Written by an international team of scientists, Ecotoxicology Modeling is of primary interest to those whose research or professional activity is directly concerned with the development and application of models in ecotoxicology. It is also intended to provide the graduate and post-graduate students with a clear and accessible text covering the main types of modeling approaches used in environmental sciences.

Download or read book Environmental Modeling written by Jerald L. Schnoor and published by Wiley-Interscience. This book was released on 2014-03-03 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Modeling, Second Edition combines engineering transport fundamentals and equilibrium aquatic chemistry. It brings a uniquely contemporary perspective to the assessment of environmental quality. In addressing key questions about fate, transport, and long-term effects of chemical pollutants in the environment, this inherently practical book gives readers the important tools they need to develop and solve their own mathematical models. The book contains detailed examples from a wide range of crucial water quality areas: conventional pollutants in rivers, eutrophication of lakes, and toxic organic chemicals and heavy metals in both surface and groundwaters.
