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.

Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.

A result of important bilateral scientific agreements between the U.S. and the Soviet Union on the fate of chemicals and pesticides in the environment. Written by experts in both countries, it familiarizes the reader with recent state-of-the-art research being conducted in the areas of agricultural management and water pollution control. A number of models are provided to give the reader a concise grasp of exposure and ecological risk assessments involving these pollutants. Focuses on the necessity to improve our deteriorating standards of public health, environmental science and technology with a total systems approach through the pooled talents of scientists and engineers.

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.

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.

Identifying and remediating environmental contamination is a complex and very expensive problem worldwide. Pollution of soil and water by pesticides is a significant issue that persists for years after the pesticide application ceases. Pesticide Properties in the Environment is a unique database compiled from extensive literature searches. It presents data on hundreds of pesticides, including their common, commercial, and scientific names, their chemical formulas, and their environmental properties including water solubility, field half-life, sorption coefficient, and vapor pressure. All data is carefully cited to original references, and is presented both in printed form and as an electronic database. Pesticide Properties in the Environment will be invaluable for environmental scientists, engineers, and consultants, as well as soil scientists and water quality specialists.
