Download or read book Free-Radical-Induced DNA Damage and Its Repair written by Clemens Sonntag and published by Springer Science & Business Media. This book was released on 2006-03-20 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The free-radical chemistry of DNA had been discussed in some detail in 1987 in my book The Chemical Basis of Radiation Biology. Obviously, the more recent developments and the concomitant higher level of understanding of mechanistic details are missing. Moreover, in the living cell, free-radical DNA damage is not only induced by ionizing radiation, but free-radical-induced DNA damage is a much more general phenomenon. It was, therefore, felt that it is now timely to review our present knowledge of free-radical-induced DNA damage induced by all conceivable free-radical-generating sources. Originally, it had been thought to include also a very important aspect, the repair of DNA damage by the cell’s various repair enzymes. Kevin Prise (Cancer Campaign, Gray Laboratory, L- don) was so kind to agree to write this part. However, an adequate description of this strongly expanding area would have exceeded the allocated space by much, and this section had to be omitted. The directors of the Max-Planck-Institut für Strahlenchemie (now MPI für Bioanorganische Chemie), Karl Wieghardt and Wolfgang Lubitz, kindly allowed me to continue to use its facilities after my retirement in 2001. Notably, our - brarian, Mrs. Jutta Theurich, and her right-hand help, Mrs. Rosemarie Schr- er, were most helpful in getting hold of the literature. I thank them very much. Without their constant help, this would have been very difficult indeed.

Download or read book Photochemical Purification of Water and Air written by Thomas Oppenländer and published by John Wiley & Sons. This book was released on 2007-06-27 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the treatment of water and exhaust gas using ultraviolet (UV) light offers both ecological and economic advantages, information on photo-initiated advanced oxidation technologies (AOTs) has been dispersed among various journals and proceedings until now. This authoritative and comprehensive handbook is the first to cover both the photochemical fundamentals and practical applications, including a description of advanced oxidation processes (AOPs) and process engineering of suitable photoreactors. The author presents various real-world examples, including economic aspects, while many references to current scientific literature facilitate access to current research topics relevant for water and air industries. Throughout, over 140 detailed figures visualize photochemical and photophysical phenomena, and help in interpreting important research results. From the foreword by James R. Bolton (President of Bolton Photosciences Inc., Executive Director of the International Ultraviolet Association (IUVA)): "Prof. Oppenländer is well qualified to write about the AOPs/AOTs, since he has contributed to this literature in a very significant manner. This book will be of considerable value to graduate students, science and engineering faculty, scientists, process engineers and sales engineers in industry, government regulators and health professionals."

Available in PDF, EPUB and Kindle. Book excerpt: Any mention of the "greenhouse effect" tends to ignite controversy. While the rising atmospheric concentrations of greenhouse gases-especially carbon dioxide- are certainly among the most pressing issues today, theoretical and perceived consequences have been subject to conjecture and misinformation. That raging debate has obscured an important fact: scientists and engineers are hard at work on methods to reduce CO2 emissions, and devise practical methods for their remediation. Greenhouse Gas Carbon Dioxide Mitigation: Science and Technology sheds light on the most recent advancements, documented by two of the world's leading researchers on CO2. Aware of the complexity and still-unknown factors behind climatic change, the authors consider the need to make CO2 mitigation viable for both environmental and economic gain. To that end, Professor Halmann offers new insights into interesting chemical pathways for the conversion of CO2 to useful products. Steinberg adds real-life engineering solutions, applicable to heavy CO2-producing industrial processes, and improving efficiency of energy conversion. Exciting theories and pilot projects are also testing the potential for CO2 utilization, conversion, reduction, and disposal. Greenhouse Gas Carbon Dioxide Mitigation: Science and Technology reports on the use of biomass, such as ocean fertilization and "energy farms," to put CO2 to practical and safe use. Professional and academic readers involved with CO2 research will find Greenhouse Gas Carbon Dioxide Mitigation: Science and Technology an invaluable roadmap for information and inspiration-a way to move beyond argument, and into action.

Download or read book Removal of MTBE with Advanced Oxidation Processes written by Michael Kavanaugh and published by IWA Publishing. This book was released on 2004-01-01 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this project was to perform a careful evaluation of the technical and economic feasibility of advanced oxidation processes (AOPs) for methyl tertiary butyl ether (MTBE) removal. Specifically, the first objective of this project was to identify and fill data gaps related to the implementation and operation of AOPs with respect to MTBE removal. The second objective was to select and optimize the design of the most promising AOP(s) as a function of water quality parameters. The third objective was to determine conceptual-level engineering costs for these selected AOPs. The AOP technologies that were evaluated as part of this study included ozone/peroxide, continuous wave UV/peroxide, pulsed UV/peroxide, and E beam. The AOP technologies were compared with treatment costs, qualitative factors (e.g., technology reliability, flexibility), and influent and treated water quality considerations. Based on the comparative analysis, it was concluded that all the AOP technologies that were evaluated in this study are capable of removing MTBE at 95% or higher efficiencies. Ozone/peroxide and continuous UV/peroxide appear to be the most feasible technologies for AOP treatment of MTBE in drinking water sources. Originally published by AwwaRF for its subscribers in 2003

Download or read book Wastewater Treatment written by D. G. Rao and published by CRC Press. This book was released on 2012-07-05 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the heterogeneous nature of water streams from diverse domestic and industrial sources, and the equally diverse nature of pollutants that can be physical, chemical, and biological in nature, their treatment methods also must be varied in nature. Responding to this complex situation, Wastewater Treatment: Advanced Processes and Technologies presents important concepts, technologies, and issues, essentially distilling the information into actionable treatment methods for various types of pollutants. Edited by experts in the field, the book explores recent advances in wastewater treatment by various technologies such as chemical methods, biochemical methods, membrane separation techniques, and by application of Fenton and solar photo Fenton methods. It emphasizes new technologies that produce clean water and energy from the wastewater treatment process and addresses sustainable water reclamation, biomembrane treatment processes and advanced oxidation processes for wastewater treatment. The editors and chapter authors judiciously blend coverage of treatment processes and technologies, making the diverse subject matter as comprehensible as possible. They tackle the difficulties of covering the gamut of advanced processes and technologies available concisely, without losing the rigor and details required for the information to be useful and applicable. Equations, figures, photographs, tables, case studies, examples, and references support the information provided in the text. These features combine to make the book an authoritative resource and practical tool for resolving wastewater treatment issues.

This book was released on 2017-09-27 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Existe una creciente preocupación medioambiental debida la presencia de microcontaminantes orgánicos en los sistemas acuáticos. La escasa eficiencia en la degradación de contaminantes orgánicos persistentes en las plantas de tratamiento de aguas residuales convencionales basadas en procesos biológicos constituye uno de los principales fuentes de su emisión en el medio ambiente. Esto significa la liberación continua en el ciclo del agua de sustancias que aunque se encuentran en muy bajas concentraciones, han sido reconocidas como potencialmente peligrosas para el medio ambiente y la salud humana. Por tanto, para la eliminación de estas sustancias se está investigando la inclusión de un tratamiento terciario en las estaciones depuradoras de aguas residuales. En este respecto, los procesos de oxidación avanzada (POA) han sido ampliamente investigados debido a la generación de radicales hidroxilos altamente reactivos, capaces de oxidar compuestos orgánicos. Entre ellos, el proceso foto-Fenton ha demostrado ser eficaz en la eliminación de microcontaminantes. Sin embargo, todavía se necesita investigar en la operación de este proceso para su aplicación en plantas de tratamiento de aguas residuales a escala real. Este trabajo ha sido diseñado para evaluar diferentes estrategias de operación del proceso foto-Fenton como tratamiento terciario para eliminar microcontaminantes en efluentes secundarios de la industria agroalimentaria (“Cítricos del Andarax S.A.”, Almería, España) y de plantas de tratamiento de aguas residuales municipales. La evaluación se ha realizado en función de las características de las distintas matrices de agua así como por la viabilidad de escalar el proceso a niveles reales utilizando un reactor de bajo costo tipo “raceway”. Los reactores “raceway” son fotorreactores extensivos formados por canales donde el líquido es movido por un agitador de palas y que permiten tratar grandes volúmenes de agua. En resumen, el trabajo presentado en esta tesis muestra que controlar el pH durante la depuración biológica de aguas residuales de industria agro-alimentaria facilita la eliminación de microcontaminantes mediante el proceso de foto-Fenton y que reduce los costes de reactivos. Además, el exceso de fango generado durante el tratamiento biológico puede ser reducido por ultrasonicación del fango purgado y degrada la mayoría de los plaguicidas absorbidos en el fango. Por otro lado, los reactores tipo “raceway” permiten altas capacidades de tratamiento para la eliminación de microcontaminantes mediante procesos de Fenton solares como la dosificación secuencial de hierro y el uso del complejo Fe3+/EDDS, habiendo demostrado ser tratamientos eficientes en la eliminación de microcontaminates y toxicidad en efluentes secundarios de depuradoras de aguas residuales.
