This book combines soil science, earth science, and environmental geochemistry, providing comprehensive background information for specialists interested in chemical-induced changes in the soil-subsurface system. Readers are introduced to the chemistry of contaminants that often disturb the natural soil-subsurface equilibrium as a result of human activity. While the soil-subsurface system has in many cases been affected by human impact, the effects of chemical contaminants on the actual matrix and properties have been largely neglected. The major focus of the book is on changes to the soil-subsurface matrix and properties caused by chemical pollution. By integrating results available in the ...
Combining earth science, subsurface hydrology and environmental geochemistry, this book provides a comprehensive background for those interested in the protection and sustainable management of the subsurface environment. The reader is introduced to the chemistry of contaminants, which usually disturb the natural equilibrium in the subsurface as a result of human activity. One focus of the book is on contaminant reactions in soil solutions. Discussions on case studies are provided.
There is growing interest in Israel's political system from all parts of the world. This Handbook provides a unique comprehensive presentation of political life in Israel from the formative pre-state period to the present. The themes covered include: political heritage and the unresolved issues that have been left to fester; the institutional framework (the Knesset, government, judiciary, presidency, the state comptroller and commissions of inquiry); citizens' political participation (elections, political parties, civil society and the media); the four issues that have bedevilled Israeli democracy since its establishment (security, state and religion, the status of Israel's Arab citizens and economic inequities with concomitant social gaps); and the contours of the political culture and its impact on Israel's democracy. The authors skilfully integrate detailed basic data with an analysis of structures and processes, making the Handbook accessible to both experts and those with a general interest in Israel.
The use of trace elements to promote biogas production features prominently on the agenda for many biogas-producing companies. However, the application of the technique is often characterized by trial-and-error methodology due to the ambiguous and scarce basic knowledge on the impact of trace elements in anaerobic biotechnologies under different process conditions. This book describes and defines the broad landscape in the research area of trace elements in anaerobic biotechnologies, from the level of advanced chemistry and single microbial cells, through to engineering and bioreactor technology and to the fate of trace elements in the environment. The book results from the EU COST Action on...
Pollution is undesirable state of the natural environment being contaminated with harmful substances as a consequence of human activities so that the environment becomes harmful or unfit for living things; especially applicable to the contamination of soil, water, or the atmosphere by the discharge of harmful substances. In addition to the harm, either present or future and known or unknown, to living beings, pollution cleanup and surveillance are enormous financial drains of the economies of the world. This volume details outstanding research covering agriculture and soil pollution.
Offering a wide overview of the most recent research on environmental nanopollutants this book gives the reader a full picture of the research on nanoparticles in the environment.
This is part of a two-book assessment of hydrolase structure/functionrelationships and the means by which these important enzymes can be betterutilized. Each book, Assessment and Emerging New Chemicals and Fate andExposure, will deal with understanding cellulase and hemicellulase action - astrategy based in macromolecular modeling, site-directed mutagenesis, activesite mapping, heterologous expression, and classical kinetic characterization.Information about new cellulase enzymes and systems and trends in the field ofglycosyl hydrolase biochemistry will be examined as well as new crystallographicstructure of important cellulases and methods for improving activity by proteinengineers.

In this updated and expanded second edition, new literature has been added on contaminant fate in the soil-subsurface environment. In particular, more data on the behavior of inorganic contaminants and on engineered nanomaterials were included, the latter comprising a group of “emerging contaminants” that may reach the soil and subsurface zones. New chapters are devoted to a new perspective of contaminant geochemistry, namely irreversible changes in pristine land and subsurface systems following chemical contamination. Two chapters were added on this topic, focusing attention on the impact of chemical contaminants on the matrix and properties of both liquid and solid phases of soil and subsurface domains. Contaminant impacts on irreversible changes occurring in groundwater are discussed and their irreversible changes on the porous medium solid phase are surveyed. In contrast to the geological time scale controlling natural changes of porous media liquid and solid phases, the time scale associated with chemical pollutant induced changes is far shorter and extends over a “human lifetime scale”.
