Available in PDF, EPUB and Kindle. Book excerpt: Launches a series that intends to deal with topics as varied as atmospheric dynamics, coastal oceanography, subsurface flow and transport, lava flow, oil spills on the sea surface, indoor contamination and clean-room technology, risk assessment, data acquisition, and stochastic models. Introduces the general principles of diffusion in the subsurface environment and discusses the implications for the fate and transport of contaminants in the soils and groundwater. Emphasizes sorption and desorption and the dissolution kinetics of organic contaminants, both of which are limited by the slow speed of molecular diffusion. Also compiles methods for calculating the diffusion coefficients of organic compounds in aqueous solution or vapor phase through natural porous media.

This book was released on 2013-11-11 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decades, environmental scientists, economists and physicists have been juggling critical issues within environmental strategies and environmental management styles in order to find a feasible medium between limited resources, long term demands and objectives, and interest groups. In the search for best management alternatives, practice has undergone a pendulum swing between stages that can be characterised as frontier economics, radical environmentalism, resource management/allocation, selective environmentalism and sustainable environmental management. The next stage of management must answer such questions as: `Can there be a global - uniform environmental strategy?', or `Based on their characteristics, can different issues, different regions and different applications have unique environmental strategies?' Based on this premise, the next stage of management may be identified as risk based sustainable environmental management. The goal of this style will be the risk based, long term, harmonious management of economic resources and environmental preservation for health, safety and prosperity of sustainable populations. When evaluation of risk or risk based ranking of management alternatives enter the picture as part of the overall puzzle, then social policy, ethics and health issues assume a very important role in the management strategy. Economic incentives and environmental constraints have to be considered harmoniously, the main emphasis being placed on protection and preservation of human health and the long term sustaining of populations.

Download or read book Partition and Adsorption of Organic Contaminants in Environmental Systems written by Cary T. Chiou and published by John Wiley & Sons. This book was released on 2003-07-07 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given the presence of a wide variety of contaminants in the environment, it is important to understand what drives a contaminant from one medium to another, as well as the manner and extent to which a contaminant associates with the different media or phases within a local environmental system. Partition and Adsorption of Organic Contaminants in Environmental Systems forms a comprehensive resource on the behavioral characteristics of contaminants so that appropriate strategies can be adopted to either prevent or minimize their adverse impacts on human welfare and natural resources. Cary Chiou’s far-reaching text depicts the processes by which nonionic organic contaminants are sorbed to natural biotic and abiotic substances. This book focuses on physical principles and system parameters that affect the contaminant uptake by soil from water, air, and other media; by fish from water; and by plants from soil and water. As contaminant uptake by natural organic substances is often predominantly a partition interaction, the partition characteristics in several solvent-water model mixtures are treated in detail to elucidate the relevant physicochemical parameters. The account of contaminant sorption to soils, fish, and plants is strengthened by companion chapters on: Fundamentals of solution theory Interphase partition equations Fundamentals of adsorption theory Vapor adsorption on mineral and carbonaceous solids No other single source in the field delivers as compelling a combination of background understanding and "state-of-the-science" comprehension of current issues. Ideally suited for a graduate-level environmental course, Partition and Adsorption of Organic Contaminants in Environmental Systems also serves as a technical guide to current and future research in the field.

Available in PDF, EPUB and Kindle. Book excerpt: In March, 1983 a workshop on Pollutants in Porous Media was hosted by the Institute of Soils and Water of the Agricultural Research Organi zation in Bet Dagan, Israel. At this workshop, the unsaturated zone be tween the soil surface and groundwater was the focal point of discus sions for scientists from various disciplines such as soil chemists, physicists, biologists and environmental engineers. Since then, the prob lem of soil and water pollution has only worsened as more and more cases of pollution caused by human activities including agriculture and industry have been revealed. A great deal of work has been carried out by environmental scientists since 1983 in elucidating the behavior of the many classes of pollutants and the complex physical, chemical, and bio logical transformations which they undergo as they move through the soil to the vadose zone and, in many cases, the groundwater. In light of this, it was felt that another meeting of specialists from the many disciplines which deal with this subject was necessary and so a Second International Workshop on the Behavior of Pollutants in Porous Media, sponsored by IUPAC (the International Union of Pure and Applied Chemistry) and IAHS (the International Association of Hydrological Sciences), was organized and held in the Institute of Soils and Water of the Agricultural Research Organization in Bet Dagan, Israel during 1987. June, The present volume is a selection of the talks presented at this second workshop and deals only with toxic organic chemicals in porous media.

Download or read book The Molecular Theory of Adsorption in Porous Solids written by Yury Konstantinovich Tovbin and published by CRC Press. This book was released on 2017-10-17 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the adsorption phenomenon the substances from the external environment the gas or liquid are absorbed by a solid surface (adsorbent). Adsorption is used to separate gaseous and liquid mixtures, for drying and purification of gases and liquids. This reference broadly explores the calculation of the equilibrium and dynamic characteristics of adsorption in porous bodies at the molecular level. Two new theories of statistical physics are presented, both developed by the author for the consistent description of the equilibrium distribution of molecules and dynamics of flows in complex porous materials to be able to solve a wide range of practical tasks in the development of new technologies.
