Book Synopsis Environmental Fate Modelling of Pesticides by : Otto Richter
Download or read book Environmental Fate Modelling of Pesticides written by Otto Richter and published by John Wiley & Sons. This book was released on 2008-07-11 with total page 293 pages. 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.

Book Synopsis Agrochemical Environmental Fate State of the Art by : Marguerite L. Leng
Download or read book Agrochemical Environmental Fate State of the Art written by Marguerite L. Leng and published by CRC Press. This book was released on 1995-04-28 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate risk assessment is critical to pesticide regulation. This authoritative reference provides an exhaustive evaluation of current agrochemical environmental fate studies, a critical review of current EPA pesticide assessment guidelines, and a wide variety of environmental simulation models. Divided into four sections, this well-organized book provides a wealth of data and information vital to anyone involved in environmental exposure assessment, groundwater, surface water, and water contamination, pesticide regulation, and environmental simulation modeling. At your fingertips, you will have the latest information on the development of meaningful environmental fate data and how this information will result in accurate assessment of potential environmental and human hazards. The inadequacy of current regulatory guidelines and the resulting nonscientific assessment of agrochemical environmental fate are discussed in detail. A wide variety of environmental fate studies are included to demonstrate the current use of data to assess environmental fate and potential hazards associated with agrochemical use. Finally, ten chapters discuss the use of computer models that have been developed for analyzing and integrating data from a variety of environmental fate studies on agrochemicals used under various field conditions.

Book Synopsis Fate of Pesticides in the Atmosphere: Implications for Environmental Risk Assessment by : Harrie F.G. van Dijk
Download or read book Fate of Pesticides in the Atmosphere: Implications for Environmental Risk Assessment written by Harrie F.G. van Dijk and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global pesticide use is currently estimated at approximately 2. 5 billion kg per year (Pimentel eta/. , 1998). To be effective, pesticides need to persist for a certain period of time. However, the longer their persistence, the greater the potential for transport of a fraction of the amount applied away from the target area. Pesticides are dispersed in the environment by water currents, wind, or biota. Pesticides can directly contaminate ground and surface waters by leaching, surface run-off and drift. Pesticides can also enter the atmosphere during application by evaporation and drift of small spray droplets, that remain airborne. Following application, pesticides may volatilise from the crop or the soil. Finally, wind erosion can cause soil particles and dust loaded with pesticides to enter the atmosphere. The extent to which pesticides enter the air compartment is dependent upon many factors: the properties of the substance in question (e. g. vapour pressure), the amount used, the method of application, the formulation, the weather conditions (such as wind speed, temperature, humidity), the nature of the crop and soil characteristics. Measurements at application sites reveal that sometimes more than half of the amount applied is lost into the atmosphere within a few days (Spencer and Cliath, 1990; Taylor and Spencer; 1990; Van den Berg et a/. , this issue).
Book Synopsis Soil and Water Quality by : National Research Council
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.
Book Synopsis Modelling of Environmental Chemical Exposure and Risk by : Jan B.H.J. Linders
Download or read book Modelling of Environmental Chemical Exposure and Risk written by Jan B.H.J. Linders and published by Springer Science & Business Media. 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.

Book Synopsis Pesticide Profiles by : Michael A. Kamrin
Download or read book Pesticide Profiles written by Michael A. Kamrin and published by CRC Press. This book was released on 1997-03-12 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticide Profiles: Toxicity, Environmental Impact, and Fate is like three books in one-it is a profile containing specific information about 137 pesticides, a primer of environmental toxicology, and an extensive trade name index. Profiles of each pesticide contain regulatory information, toxicity assessments, environmental fate data, physical properties, and acceptable exposure limit values. What these values and data mean in terms of human toxicity is clearly interpreted as well. The book also describes the meaning of carcinogenicity and how it is assessed in non-technical terms the non-expert can understand. Readers with a technical background are provided with the data to make their own judgments. In addition to information about specific pesticides, there are sections on general classes of pesticides, such as organophosphates. This information allows readers to make inferences about any pesticide in a class, even if a profile is not provided. Pesticide Profiles: Toxicity, Environmental Impact, and Fate goes beyond the usual listings of toxicity values or environmental half-lives to offer a broad understanding to readers of various backgrounds and interests.
