Download or read book Simulation and Assessment of Chemical Processes in a Multiphase Environment written by Ian Barnes and published by Springer Science & Business Media. This book was released on 2008-10-21 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book reviews the current state of knowledge on the chemical and physical processes occurring in the environmental media (i) the atmosphere, (ii) the aqueous phase and (iii) soil and identifies the strengths and weaknesses of the chemical mechanisms (both explicit and condensed) currently available to simulate the multimedia environmental chemistry of volatile organic compounds (VOCs) and particulate matter in these media. Contributions examine how well this knowledge has been incorporated into different types of CT models and appraise the current status and significant issues in the development and usage of the models. Model simulations of some real world chemical perturbations to the Earth system are presented which appraise the performance of the models in relation to "real world" observations. Serious caveats in our understanding of chemical processes and their simulation in the various compartments of the Earth system are highlighted and areas are identified that need urgent improvement, in particular with respect to environmental security.

Download or read book Chemistry of the Climate System written by Detlev Möller and published by Walter de Gruyter. This book was released on 2010-12-23 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is one of the biggest challenges facing the modern world. The chemistry of the air within the framework of the climate system forms the main focus of this monograph. This problem-based approach to presenting global atmospheric processes begins with the chemical evolution of the climate system in order to evaluate the effects of changing air composition as well as possibilities for interference within these processes. Chemical interactions of the atmosphere with the biosphere and hydrosphere are treated in the sense of a multi-phase chemistry. From the perspective of a "chemical climatology" the book offers an approach to solving the problem of climate change through chemistry.

Download or read book Global Aspects of Atmospheric Chemistry written by and published by Springer Science & Business Media. This book was released on 1999-03-01 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric Chemistry has been a rapidly growing field with a recent focus on the major aspects of global environmental change, including stratospheric ozone depletion, UV-B change, and global warming. This book describes recent developments in our understanding of the global aspects of the chemistry in the main parts of the atmosphere, troposphere, and stratosphere, as obtained from field observations, laboratory investigations, and modeling studies. Although this chemistry is largely driven by reactions between gas phase species, recent progress made in the understanding of chemical reactions occuring in clouds and on the surface of aerosols is also reported.

Download or read book Tropospheric Modelling and Emission Estimation written by Adolf Ebel and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The end result of policy-related experimental and theoretical scientific work on the abatement of atmospheric emissions is a hierarchy of computer models that can be used to analyse and predict the behaviour of pollutants on urban, local regional and global scales. Such models are required to simulate an extremely complex natural situation in which a non-linear chemistry must be included together with the vagaries of the meteorology and the terrain. This book describes recent advances in the development and application of models on all scales, and in the techniques for the estimation and verification of emissions. It includes reviews of recent work together with detailed results and provides a useful picture of the field in a European context.

Download or read book Aquatic and Surface Photochemistry written by George R. Helz and published by CRC Press. This book was released on 2018-01-10 with total page 571 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic and Surface Photochemistry provides a broad overview of current research in the emerging field of environmental aquatic and surface photochemistry. Selected reviews and current research articles are blended to provide an in-depth treatment of various aspects of this research area. The first part of the text deals with photochemistry in the environment, covering recent research on the following topics: aquatic photochemistry of organic pollutants and agrochemicals, photochemical cycling of carbon and transition metals (especially iron), photochemical formation of reactive oxygen species in natural waters, photoreaction in cloud and rain droplets, and photoreactions on environmental surfaces (soil, ash, metal, oxide). The second part provides discussions and data on both heterogeneous photocatalytic and homogeneous processes, with topics ranging from applications to mechanistic studies. These chapters illustrate the wide diversity of pollutant classes that are degradable by photochemical techniques and the effects of various reaction conditions on the rates and efficiency of the techniques. Current kinetic studies are presented, which provide new information about the role of adsorption and the nature of the reactive oxidizing species that mediate these photoremediation processes.This book will interest civil, chemical, and environmental engineers, as well as chemists, soil scientists, geochemists, and atmospheric chemists.

Download or read book Uniform Supersonic Flows In Chemical Physics Chemistry Close To Absolute Zero Studied Using The Cresu Method written by Bertrand R Rowe and published by World Scientific. This book was released on 2022-05-18 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radioastronomy has painted an extraordinary picture of the Galactic interstellar medium, which displays an amazing organization and structuring of matter from very hot ultra-diluted media to very cold denser milieus considered as the cradles of stars. In these latter environments, the discovery of a chemical diversity of molecules, including those associated with precursors to life itself, immediately brought to light the question of the mechanisms leading to their formation and persistence at temperatures as low as 10 K. The chemical networks developed to understand telescope observations required a great deal of physical and chemical parameters relevant to interstellar conditions, particularly at very low temperatures. These included the rate coefficients of thousands of gas phase chemical reactions. Such data were missing in the 1970s, when the very first molecular discoveries were made. Then, in the early eighties, it was realized that uniform supersonic flows were ideal chemical reactors to study reaction kinetics at interstellar temperatures.Uniform Supersonic Flows in Chemical Physics reviews 40 years of use of such reactors, the so-called CRESU machines, focusing on major breakthroughs brought to chemical physics, physical chemistry, astrophysics and astrochemistry by the various experiments carried out with such apparatuses. The wealth of kinetic data at very low temperatures provided new targets for the predictions of theory, with new theoretical methods being developed to explain observed behavior. The first two chapters describe the physical context of reaction kinetics at very low temperatures and the requirements needed to run optimally such uniform supersonic flows, together with a historical perspective. Chapters 3 to 9 describe the various families of chemical processes that have been explored within the CRESU technique, highlighting major advances and offering an exhaustive up-to-date bibliography. Chapters 10 and 11 show how these experimental results have helped in improving the ideas in quantum chemistry and interstellar modeling. The book concludes with an overview of potential perspectives and new routes to be explored.
