Download or read book Scientific Assessment of Stratospheric Ozone written by Daniel L. Albritton and published by . This book was released on 1996-07-01 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: A scientific review of the current understanding of stratospheric ozone. The focus of this assessment is on four major aspects of stratospheric ozone: (1) polar ozone (gas phase chemistry, dynamical processes, temperature trends), (2) global trends (vertical ozone, stratospheric temperatures, stratospheric aerosols), (3) theoretical predictions, and (4) halocarbon ozone depletion and global warming potentials. Useful as essential scientific input to policy decisions regarding the safeguarding of the ozone layer. Extensive bibliography.

Download or read book Volatile Organic Compounds in the Atmosphere written by R M Harrison and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in volatile organic compounds (VOCs) as air pollutants has increased dramatically in recent years. This book covers a number of very topical issues concerning VOCs, including stratospheric ozone depletion due to CFCs, and the properties of alternative substances; the role of VOCs in the photochemical formation of lower atmosphere (tropospheric) ozone; and the problem of the direct toxicity of VOCs such as benzene and formaldehyde. This Issue reviews our current knowledge of VOCs, drawing upon the expertise of renowned experts and major national and international research programmes. It examines man-made and natural sources, as well as pathways and chemical reactions in the atmosphere. It also looks closely at the sources and concentrations of VOCs indoors, where humans are most likely to be exposed to them. Volatile Organic Compounds in the Atmosphere describes techniques used for the calculation of emissions inventories and strategies for control, and explores the many Government policy matters relating to VOCs. It provides readers with in-depth, clearly explained coverage of the many complex scientific and policy issues surrounding VOCs in the atmosphere.

Download or read book Environmental Assessment of Products written by Henrik Wenzel and published by Springer Science & Business Media. This book was released on 1997-12-31 with total page 854 pages. Available in PDF, EPUB and Kindle. Book excerpt: This major two volume work presents a new decision making tool which enables manufacturers and scientists to undertake life cycle assessment (LCA) of new products from the design and development stages. The methodology allows the environmental consequences of a product to enter into decision making in the same way as traditional commercial parameters such as price, quality etc. Significantly, it is in accordance with international consensus, as defined by SETAC (Society of Environmental Toxicology and Chemistry) and ISO (International Organization for Standardization). Moreover, the individual steps have been made operational through the creation of a collection of tools for assessment. The books are derived from the Environmental Design of Industrial Products (EDIP) programme organized by the Technical University of Denmark and five leading Danish companies. The project was sponsored by the Danish Environmental Protection Agency (EPA) and the Confederation of Danish Industries.

This book was released on 2013-06-29 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic troposphere (0 to ca. 8 km) plays an important role in environmental concerns for global change. It is a unique chemical reactor influenced by human activity and the Arctic ocean. It is surrounded by industrialized continents that in winter contribute gaseous and particulate pollution (Arctic haze). It is underlain by the flat Arctic ocean from which it is separated by a crack-ridden ice membrane 3 to 4 m thick. Ocean to atmosphere exchange of heat, water vapor and marine biogenic gases influence the composition of the reactor. From September 21 to December 21 to March 21, the region north of the Arctic circle goes from a completely sunlit situation to a completely dark one and then back to light. At the same time the lower troposphere is stably stratified. This hinders vertical mixing. During this light period, surface temperature reaches as low as -40°C. In this environment, chemical reactions involving sunlight are generally much slower than further south. Thus, the abundance of photochemically reactive compounds in the atmosphere can be high prior to polar sunrise. Between complete dark in February and complete light in April, a number of chemical changes in the lower troposphere take place.

Download or read book Molecular Similarity and Reactivity From Quantum Chemical to Phenomenological Approaches written by Ramón Carbó and published by Springer Science & Business Media. This book was released on 1995-07-31 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Similarities in chemical reactivity depend on molecular properties, and are ultimately dependent on the similarities of electronic structures. Fundamentally, quantum chemical similarities are manifested in similarities of molecular behaviour. This book covers both the quantum chemical origins and the methods of phenomenological descriptions of molecular similarity. The emphasis on reactivity is a unique feature. The exposition of computational methods and the prediction of reactivities, as well as the description of actual computer programs constitute important aspects of the book. Specific applications in drug design and techniques for the interpretation of the roles of functional groups in reactivity are of interest in molecular engineering. The selection of topics provides a detailed and balanced introduction to the field of similarity-based assessment of chemical reactivity. For researchers and graduate students in both fundamental chemistry and applied fields, such as biochemistry, pharmacology and drug design.
