Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with modelling the fate of organic substances in the soil. Once a chemical enters the soil it is subject to various transformation processes. It partitions between the liquid, solid and gaseous phase, it is sorbed to different binding sites with a different strength of bonding, it may decay by a simple chemical process or it may be transformed by microorganisms. Solute transport through soil and subsurface is mediated by water flow and is strongly influenced by solute sorption. To complicate matters, soil structures are heterogeneous. All these processes are embedded in a spatio-temporal hierarchy. The book brings together many different aspects of environmental fate modelling of pesticides comprising such diverse subjects as, e.g., compartment theory, nonlinear biological degradation models, modelling toxicity, parameter identification, coupling of physical and biological processes, pedotransfer functions, translation of models across scales, coupling geographical information systems with models, and FUZZY-approaches.

Download or read book Fate of Pesticides in the Atmosphere Implications for Environmental Risk Assessment written by Gezondheidsraad (Netherlands) and published by Springer Science & Business Media. This book was released on 1999-10-31 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of an international workshop on the issue of `Fate of Pesticides in the Atmosphere - Implications for Risk Assessment' held in 1998 in The Netherlands. Topics include emission, dispersion, transport and transformations of pesticides in the atmosphere, and the ecotoxicological risks of pesticides in remote areas. Laboratory and field measurements are reviewed, and modeling of the atmospheric processes that affect pesticides are discussed. Various risk assessment approaches are presented, and possible statutory environmental criteria that could be incorporated into pesticide regulation in order to limit their atmospheric dispersion are explored. This is the first book to present a complete review of the science of this subject with the aim of investigating the possibilities of incorporating long-range transport potential of pesticides into protocols for estimating their environmental risks and their registration. This book will be important for atmospheric and pesticide scientists, pesticide manufacturers, pesticide regulators, and risk assessors.

This book was released on 2012-12-06 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical models are being increasingly used to estimate the concentrations of a wide range of substances in the environment for a variety of reasons, including government control and legislation, and risk and hazard estimation. Exposure assessment has to be performed for many types of substances, including pesticides, industrial chemicals, pollutants, accidental discharges, etc. The interpretation of the results of model equations should always bear in mind the purpose for which the model used was built in the first place. Further, models are always an abstraction of reality, requiring simplifying assumptions to keep the models within the restraints posed by computer performance and/or scientific knowledge. The present book treats the theme of modelling chemical exposure and risk in terms of four main topics: model characteristics, applications, comparison of estimated with measured concentrations, and modelling credibility.

Available in PDF, EPUB and Kindle. Book excerpt: Time-variable exposure profiles of pesticides are more often the rule than exception in the surface waters of agricultural landscapes. There is, therefore, a need to adequately address the uncertainties arising from time-variable exposure profiles in the aquatic risk assessment procedure for pesticides.

Download or read book Handbook of Environmental Fate and Exposure Data for Organic Chemicals written by Philip H. Howard and published by CRC Press. This book was released on 1993-03-19 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 5-volume set allows you to assess the health and environmental effects of chemicals by determining the routes of exposure of the chemical to sensitive organisms. Environmental Fate and Exposure of Organic Chemicals provides relevant facts on how individual chemicals behave in the environment and how humans and environmental organisms are exposed to the chemicals during their production, rise, transport, and disposal. Each chemical is prepared by one of the best-known organizations in environmental fate and exposure and is peer-reviewed by a panel of expert scientists. The information on each chemical includes all experimental values and references for physical properties, all chemical fate studies, and all available monitoring data and interpretative summaries.

Download or read book Soil and Water Quality written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can the United States meet demands for agricultural production while solving the broader range of environmental problems attributed to farming practices? National policymakers who try to answer this question confront difficult trade-offs. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. Timely and comprehensive, the volume has important implications for the Clean Air Act and the 1995 farm bill. Advocating a systems approach, the committee recommends specific farm practices and new approaches to prevention of soil degradation and water pollution for environmental agencies. The volume details methods of evaluating soil management systems and offers a wealth of information on improved management of nitrogen, phosphorus, manure, pesticides, sediments, salt, and trace elements. Landscape analysis of nonpoint source pollution is also detailed. Drawing together research findings, survey results, and case examples, the volume will be of interest to federal, state, and local policymakers; state and local environmental and agricultural officials and other environmental and agricultural specialists; scientists involved in soil and water issues; researchers; and agricultural producers.

Download or read book Handbook of Physical Chemical Properties and Environmental Fate for Organic Chemicals Second Edition written by Donald Mackay and published by CRC Press. This book was released on 2006-03-14 with total page 1000 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transport and transformation processes are key for determining how humans and other organisms are exposed to chemicals. These processes are largely controlled by the chemicals’ physical-chemical properties. This new edition of the Handbook of Physical-Chemical Properties and Environmental Fate for Organic Chemicals is a comprehensive series in four volumes that serves as a reference source for environmentally relevant physical-chemical property data of numerous groups of chemical substances. The handbook contains physical-chemical property data from peer-reviewed journals and other valuable sources on over 1200 chemicals of environmental concern. The handbook contains new data on the temperature dependence of selected physical-chemical properties, which allows scientists and engineers to perform better chemical assessments for climatic conditions outside the 20–25-degree range for which property values are generally reported. This second edition of the Handbook of Physical-Chemical Properties and Environmental Fate for Organic Chemicals is an essential reference for university libraries, regulatory agencies, consultants, and industry professionals, particularly those concerned with chemical synthesis, emissions, fate, persistence, long-range transport, bioaccumulation, exposure, and biological effects of chemicals in the environment. This resource is also available on CD-ROM
