Presented here are authoritative and up-to-date assessments of the homogenous and heterogenous chemical and physical processes occuring in the troposphere and stratosphere, especially during the "ozone hole" event. The book begins with an overview of atmospheric chemistry, followed by reviews of relevant homogenous reactions in the gas phase and the microphysics and physical chemistry of heterogenous processes that occur on, or in aerosols, rain and ice. Low temperature laboratory studies are compared with related fieldwork measurements, particularly in relation to the formation and composition of polar stratospheric clouds. Also discussed are measurements in glacial ice. Finally chemical modelling of the troposphere and stratosphere, including heterogenous processes, is reviewed.

This book brings together, for the first time, the results of recent research in areas ranging from the chemistry of cold interstellar clouds (10-20 K), through laboratory studies of the spectroscopy and kinetics of ions, radicals and molecules, to studies of molecules in liquid helium droplets, to attempts to create molecular (as distinct from atomic) Bose-Einstein condensates.

Environmental and Low-Temperature Geochemistry presents conceptual and quantitative principles of geochemistry in order to foster understanding of natural processes at and near the earth’s surface, as well as anthropogenic impacts on the natural environment. It provides the reader with the essentials of concentration, speciation and reactivity of elements in soils, waters, sediments and air, drawing attention to both thermodynamic and kinetic controls. Specific features include: • An introductory chapter that reviews basic chemical principles applied to environmental and low-temperature geochemistry • Explanation and analysis of the importance of minerals in the environment • Principles of aqueous geochemistry • Organic compounds in the environment • The role of microbes in processes such as biomineralization, elemental speciation and reduction-oxidation reactions • Thorough coverage of the fundamentals of important geochemical cycles (C, N, P, S) • Atmospheric chemistry • Soil geochemistry • The roles of stable isotopes in environmental analysis • Radioactive and radiogenic isotopes as environmental tracers and environmental contaminants • Principles and examples of instrumental analysis in environmental geochemistry The text concludes with a case study of surface water and groundwater contamination that includes interactions and reactions of naturally-derived inorganic substances and introduced organic compounds (fuels and solvents), and illustrates the importance of interdisciplinary analysis in environmental geochemistry. Readership: Advanced undergraduate and graduate students studying environmental/low T geochemistry as part of an earth science, environmental science or related program.

Recent studies have demonstrated a link between ozone changes caused by human activities and changing UV levels at the Earth's surface, as well as a link to climate through changes in radiative forcing and links to changes in chemical composition. This book draws together key scientists who provide state of the art contributions on the variable ozone layer and the interplay of longwave and shortwave radiative interactions which link ozone, the climate and UV issues.

Some Problems of Chemical Kinetics and Reactivity, Volume 1 consists of calculations on radical and radical chain reactions. The subject bond dissociation energies are fully discussed. The concept of uniradical reactivities is comprehensively explained. Isomerizations are a class of radical reactions in which the free valency takes another bond in the same radical. The text provides sample of experiments on the subject. The book contains a section on polar factors in organic reactions. Polymerizations are another concept covered in the book. Subjects such as the reactions of biradicals, the start and end of a chain reaction, and ions of variable valency are explained. A separate chapter of the book focuses on the kinetics of chain reactions. The cracking of hydrocarbons such as the alkane is analyzed in detail. The oxidation of hydrocarbons is another topic explained in the book. The text will provide excellent insight for chemists, students, and researchers in the field of chemistry.

About three years ago Catherine de Berg and I published a short article in Nature in which we attempted to explain why the chemistry of the atmosphere of the Earth is today so completely different from that of our two neighbor ing planets, Mars and Venus. Our atmosphere is composed mainly of N2 and O with traces of A, H0, CO , 0 , etc. , while the atmospheres of both 2 2 2 3 Mars and Venus are almost entirely made up of CO , Also, the Earth appears 2 to be the only one ofthe three planets which has oceans ofliquid water on the surface. Since the presence of liquid water on Earth is probably an essential requirement for life to have originated and evolved to its present state, the question of the apparent absence ofliquid water on Mars and Venus suddenly acquires significant proportions. In our paper in Nature, and later in a more detailed discussion of the subject (Planetary Atmospheres, in Exobiology, edited by C. Ponnamperuma, North Holland Publishing Co. ), we tried to describe why we believe that in the early history of the solar system all the terrestrial planets lost the atmospheres of H2 and He which they had acquired from the solar nebula at the time of their formation. These planets, completely devoid of atmos pheres, like the Moon today, started accumulating new gases which were exhumed from the interior by the commencement of volcanic activity.
