Refractory Organic Substances in the Environment


Book Description

Refractory organic substances (ROS) are an essential part of the biogeochemical carbon cycle. Wherever there is life on earth, there will also be ROS in the form of poorly biodegradable leftovers of organisms and as a source for new life. Furthermore, it is now beyond doubt that ROS are closely related to the carbon intensity identified as one of the driving forces in the dynamics of green house gas emission, such that ROS play a key role in sustainable development. 'Refractory Organic Substances in the Environment' provides the results of six years of top-priority research, funded by the Deutsche Forschungsgemeinschaft (DFG). This research program investigated the structure and function of ROS in different parts of the environment, from a chemical, physical, biological, and soil scientific point of view. It included the first systematic study of a set of reference samples from Central Europe, originating from a bog lake, soil seepage water, groundwater, and from the wastewaters of a brown coal processing plant and a secondary effluent. Thus, this work not only highlights the structural features obtained from the application of advanced analytical tools, but also the function in anthropogenically influenced aquatic systems and soils. Of special interest to students and researchers in life sciences.

Fate and Transport of Organic Chemicals in the Environment


Book Description

Fate and Transport provides the equations and background information you need to predict the fate and transport of chemicals in air, water, soil, flora, and fauna, and to prevent your exposure to toxic chemicals. Featuring 22 new mathematical calculations for predicting the fate and transport of 100 non-pesticide organic compounds, this Third Edition provides you with easy-to-read explanations of how chemicals travel through the environmental compartments, how they break down, and how key physical and chemical properties of chemicals (including water solubility, volatility, and soil sorbtion or adsorption) affect fate and transport. The book also addresses methods for predicting pesticide and fish hazards, offer complete samples of calculations and exposure analyses, includes date for 203 commonly encountered chemical substances, and explains hazard prediction based on chemical structure.




Metals in Society and in the Environment


Book Description

This book presents new results on metal fluxes from society to the environment, on metal speciation in water, soil and sediment, and its mobility, biological uptake and toxicity. New approaches, like the Acid Volatile Sulphide (AVS) concept to predict metal bioavailability in sediments, and the Biotic Ligand Model to calculate the toxicity of metals to aquatic organisms, are critically evaluated, with a focus on copper, nickel, zinc, and, chromium.




Humic Matter in Soil and the Environment


Book Description

The field of humic matter research has undergone drastic changes in concepts and principles since the first edition of Humic Matter in Soil and the Environment: Principles and Controversies was published more than a decade ago. Still the only book of its kind specifically addressing humic acid principles and controversies, the Second Edition presen




Treatise on Geochemistry


Book Description

This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry. In addition, the original Volume 1 on "Meteorites, Comets, and Planets" was expanded into two separate volumes dealing with meteorites and planets, respectively. These additions increased the number of volumes in the Treatise from 9 to 15 with the index/appendices volume remaining as the last volume (Volume 16). Each of the original volumes was scrutinized by the appropriate volume editors, with respect to necessary revisions as well as additions and deletions. As a result, 27% were republished without major changes, 66% were revised and 126 new chapters were added. In a many-faceted field such as Geochemistry, explaining and understanding how one sub-field relates to another is key. Instructors will find the complete overviews with extensive cross-referencing useful additions to their course packs and students will benefit from the contextual organization of the subject matter Six new volumes added and 66% updated from 1st edition. The Editors of this work have taken every measure to include the many suggestions received from readers and ensure comprehensiveness of coverage and added value in this 2nd edition The esteemed Board of Volume Editors and Editors-in-Chief worked cohesively to ensure a uniform and consistent approach to the content, which is an amazing accomplishment for a 15-volume work (16 volumes including index volume)!




Perchlorate in the Environment


Book Description

Based on a symposium sponsored by the Environmental Division of the American Chemical Society, Perchlorate in the Environment is the first comprehensive book to address perchlorate as a potable water contaminant. The two main topics are: analytical chemistry (focusing on ion chromatography and electrospray ionization mass spectrometry), and treatment or remediation. Also included are topics such as ion exchange, phytoremediation, bacterial reduction of perchlorate, bioreactors, and in situ bioremediation. To provide complete coverage, background chapters on fundamental chemistry, toxicology, and reulatory issues are also included. The authors are environmental consultants, government researchers, industry experts, and university professors from a wide array of disciplines.




Carbon and Nitrogen in the Terrestrial Environment


Book Description

Carbon and Nitrogen in the Terrestrial Environment is a comprehensive, interdisciplinary description of C and N fluxes between the atmosphere and the terrestrial biosphere; issues related to C and N management in different ecosystems and their implications for the environment and global climate change; and the approaches to mitigate emission of greenhouse gases. Drawing upon the most up-to-date books, journals, bulletins, reports, symposia proceedings and internet sources documenting interrelationships between different aspects of C and N cycling in the terrestrial environment, Carbon and Nitrogen in the Terrestrial Environment fills the gap left by most of the currently available books on C and N cycling. They either deal with a single element of an ecosystem, or are related to one or a few selected aspects like soil organic matter (SOM) and agricultural or forest management, emission of greenhouse gases, global climate change or modeling of SOM dynamics.
