Download or read book Ecology of Humic Substances in Freshwaters written by Christian Steinberg and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humic Substances color all waters more or less brown. Their concentrations exceed all carbon of living organisms by at least one order of magnitude. Opposite to former paradigms, they participate in almost any metabolic pathway. They protect against UV-irradation, enable indirect photolysis and, thus, purify hazardous chemicals, they provide inorganic and organic nutrients, may form cryptic genes with DNA and dampen metabolic fluctuations. More recently they can increase adverse effects of hazardous chemicals and they can directly interfere with organisms. The book tries to relate effects to structural features.

Download or read book Use of Humic Substances to Remediate Polluted Environments From Theory to Practice written by Irina V. Perminova and published by Springer Science & Business Media. This book was released on 2006-04-07 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective remediation of polluted environments is a priority in both Eastern and Western countries. In the U.S. and Europe, remediation costs generally exceed the net economic value of the land. As a result, scientists and engineers on both sides of the Atlantic have aggressively tried to develop novel technologies to meet regulatory standards at a fraction of the costs. In situ remediation shows considerable promise from both technical and economic perspectives. In situ technologies that deploy natural attenuating agents such as humic substances (HS) may be even more cost effective. Numerous studies have shown humics capable of altering both the chemical and the physical speciation of the ecotoxicants and in turn attenuate potential adverse environmental repercussions. Furthermore, the reserves of inexpensive humic materials are immense. Which suggests HS portend great promise as inexpensive amendments to mitigate the environmental impacts of ecotoxicants and as active agents in remediation. To elucidate emerging concepts of humics-based remediation technologies, we organized the NATO Advanced Research Workshop (ARW), entitled "Use of humates to remediate polluted environments: from theory to practice", held on September 23-29, 2002 in Zvenigorod, Russia (see the web-site http://www.mgumus.chem.msu.ru/arw).
Download or read book Refractory Organic Substances in the Environment written by Fritz Hartmann Frimmel and published by John Wiley & Sons. This book was released on 2008-01-08 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the mechanisms associated with metal complexes and the sequestering metal contaminants in the environment is essential for effective remediation. Heavy Metal Release in Soils describes and quantifies desorption/release kinetics and dissolution reactions in the release of heavy metals from soil. The book focuses on: New techniques - microscopic surface techniques, NMR and electrophoresis, XAFS, SFM, and time-resolved ATR-FTIR Theoretical analysis and kinetic approaches - adsorption/desorption hysteresis, competitive sorption and transport, multi-component models, speciation kinetics, isotherms and soil and metal parameters, and the role of soil properties on transport Applications - arsenic speciation and mobility in contaminated soils, modeling activity of CD, Zn, and Cu in contaminated soils, and in situ chemical immobilization A timely addition to the literature, this book highlights the desorption/release mechanisms for the purpose of resolving remediation dilemmas in contaminated environments. It gives you the added advantage of case studies at both the microscopic and macroscopic scales, and provides both experimental and numerical investigations. With contributions from an international panel of authors, Heavy Metals Release in Soils fills a gap in the current literature concerned with subsurface contaminant fate and transport processes.

Download or read book Chemical Lake Restoration written by Miltiadis G. Zamparas and published by Springer Nature. This book was released on 2021-07-30 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to structure, in a complete and sequential way, the mainstream technical knowledge which is related to eutrophication control. The book considers the development of innovative technologies for phosphate removal, while supporting the restoration of currently degraded lakes and reservoir systems. In addition, this book contains key-aspects of future benchmark interests being specially framed under the ongoing development of a circular economy. In particular, the book will contribute to a better understanding of the problem of internal P-loads and P-sources disposition towards a more effective control of nutrients’ enrichment in lakes. The chemical routes and environmental fate of such lake nutrients will be viewed in the light of innovative technologies (engineering dimensions) and circular economy perspectives (economics dimensions). The main theme extends to an economic appreciation of environmental polluted aquifers. The book will appeal to an interdisciplinary audience, covering a wide spectrum of scientific fields, such as environment, physical chemistry, surface chemistry, interfacial phenomena, coastal engineering, bio-engineering, environmental policy makers, and economists.
