Download or read book Environmental Geochemistry in the Tropics written by Julio Cesar Wasserman and published by Springer. This book was released on 2006-04-10 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Held in 1993 in Niterói, Brazil, the first International Conference on Environmental Geochemistry in Tropical Countries established a starting point for this book. The book opens with a discussion of the points that arose during the closing session, summarised by Dr. E.K. Duursma: The Environment in the Tropics Remains Unknown. Most of the processes that occur in temperate environments turn out to be completely different in the tropics. This can already be seen in Chapter 3, where estimates of radionuclide transfer factors reach values considerably greater than in temperate areas. The utilisation of variables measured in temperate environments for modelling of the tropics can result in completely erroneous conclusions and, worse, inefficient remediation solutions.

Download or read book Regolith Exploration Geochemistry in Tropical and Subtropical Terrains written by C. R. M. Butt and published by Elsevier Publishing Company. This book was released on 1992 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hardbound. The use of exploration geochemistry has increased enormously in the last decade. The present volume specifically addresses those geochemical exploration practices appropriate for tropical, sub-tropical and adjacent areas - in environments ranging from rainforest to desert. Practical recommendations are made for the optimization of sampling, and analytical and interpretational procedures for exploration according to the particular nature of tropically weathered terrains. The underlying theme is the recognition that regions between 35N and 35S in particular have a common history of deep chemical weathering and lateritization during the late Mesozoic and early Tertiary. This has had a profound and lasting effect, so that the surface geochemical expressions of mineralization throughout these regions have many similar features, with local modification due to more recent weathering under changed climates.The volume discusses the da

It shows how different plants are suited for phytoremediation, explains the role of toxicants in the environment, and analyses their effects and risks in the food chain at a global level. It also reviews the extraction methods of toxicants from plants after they are exposed to phytoremediation. Features: Summarizes the phytoremediation technology for effective remediation Describes different types of pollutants in soils that render food products useless Identifies the role of phytoremediation in the environment and its advantages and disadvantages Explains the role of phytoexclusion and phytostabilization in foods and food safety Includes many case studies to describe the extraction protocols in postharvest for food safety This book is intended for practitioners in public and private companies involved in soil remediation and food production, as well as graduate students and academics, in both developed and developing countries, who are involved in soil and environmental sciences, the food industry, agriculture, and biotechnology.
Download or read book Environmental Chemistry written by H J M Bowen and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.

Download or read book Geochemistry at the Earth s Surface written by Andreas Bauer and published by Springer. This book was released on 2014-08-27 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geochemistry at the surface of the earth is dominated by two somewhat antagonistic forces: chemical reactions which attempt to attain a steady state (equilibrium) and geological movement of materials in time and space which changes the parameters that control chemical equilibrium. Another aspect that is extremely important to earth surface geochemistry is the effect of plants on the chemical and physical stability of materials (soils). Plant systems in fact work against the normal chemical changes (loss of silica, potassium, etc.) and the normal physical changes (stabilizing fine grained materials (clays) in the surface zones to avoid erosion). Biological effects are clearly seen in redox effects in the various parts of the earth surface movement cycle; soil formation, stream transport, sedimentation. This book attempts to outline these different parameters and their interactions as they affect earth surface geochemistry in order to give a better understanding of movement and accumulation of elements at the surface of the earth.

This book was released on 2011-07-30 with total page 573 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent critiques of air quality management approaches currently employed in developed and many developing countries have suggested that efficiencies could be achieved if air quality management practices shifted from pollutant-by-pollutant approaches to a comprehensive multipollutant approach in which emission reduction decisions are based on relative risk and evaluated on their effectiveness in meeting environmental and health goals. This book assesses our technical readiness to undertake such an approach, and it outlines the technical developments that will be needed to achieve a risk-based approach air quality management that includes means for measuring the effectiveness of management decisions.

Download or read book Environmental and Low Temperature Geochemistry written by Peter Ryan and published by John Wiley & Sons. This book was released on 2019-12-16 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental and Low-Temperature Geochemistry presents conceptual and quantitative principles of geochemistry in order to foster understanding of natural processes at and near the earth’s surface, as well as anthropogenic impacts and remediation strategies. It provides the reader with principles that allow prediction of concentration, speciation, mobility and reactivity of elements and compounds in soils, waters, sediments and air, drawing attention to both thermodynamic and kinetic controls. The scope includes atmosphere, terrestrial waters, marine waters, soils, sediments and rocks in the shallow crust; the temporal scale is present to Precambrian, and the spatial scale is nanometers to local, regional and global. This second edition of Environmental and Low-Temperature Geochemistry provides the most up-to-date status of the carbon cycle and global warming, including carbon sources, sinks, fluxes and consequences, as well as emerging evidence for (and effects of) ocean acidification. Understanding environmental problems like this requires knowledge based in fundamental principles of equilibrium, kinetics, basic laws of chemistry and physics, empirical evidence, examples from the geological record, and identification of system fluxes and reservoirs that allow us to conceptualize and understand. This edition aims to do that with clear explanations of fundamental principles of geochemistry as well as information and approaches that provide the student or researcher with knowledge to address pressing questions in environmental and geological sciences. New content in this edition includes: Focus Boxes – one every two or three pages – providing case study examples (e.g. methyl isocyanate in Bhopal, origins and health effects of asbestiform minerals), concise explanations of fundamental concepts (e.g. balancing chemical equations, isotopic fractionation, using the Keq to predict reactivity), and useful information (e.g. units of concentration, titrating to determine alkalinity, measuring redox potential of natural waters); Sections on emerging contaminants for which knowledge is rapidly increasing (e.g. perfluorinated compounds, pharmaceuticals and other domestic and industrial chemicals); Greater attention to interrelationships of inorganic, organic and biotic phases and processes; Descriptions, theoretical frameworks and examples of emerging methodologies in geochemistry research, e.g. clumped C-O isotopes to assess seawater temperature over geological time, metal stable isotopes to assess source and transport processes, X-ray absorption spectroscopy to study oxidation state and valence configuration of atoms and molecules; Additional end-of-chapter problems, including more quantitatively based questions. Two detailed case studies that examine fate and transport of organic contaminants (VOCs, PFCs), with data and interpretations presented separately. These examples consider the chemical and mineralogical composition of rocks, soils and waters in the affected system; microbial influence on the decomposition of organic compounds; the effect of reduction-oxidation on transport of Fe, As and Mn; stable isotopes and synthetic compounds as tracers of flow; geological factors that influence flow; and implications for remediation. The interdisciplinary approach and range of topics – including environmental contamination of air, water and soil as well as the processes that affect both natural and anthropogenic systems – make it well-suited for environmental geochemistry courses at universities as well as liberal arts colleges.
