Download or read book Environmental Chemistry written by R. Raiswell and published by Elsevier. This book was released on 2013-10-22 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Chemistry provides an introduction to fundamental concepts in environmental chemistry. The book emerged from a short lecture and practical course given to first year students in the School of Environmental Sciences, University of East Anglia. It adopts the earth-air-water factory as an analogue to illustrate the way in which chemical principles operate in the environment. The book traces the hydrological cycle and the chemical processes which occur as water, with its dissolved and particulate load, moves from the atmosphere onto the land surface, into rivers, lakes, and oceans and is eventually incorporated into marine sediment. A glossary of terms is provided for readers who do not have an extensive background in chemistry. Although aimed at first year students studying environmental sciences, chemistry, geology, biology, or other science subjects, this book should also appeal to sixth formers studying chemistry or other sciences to ""A"" level, as well as to anyone with (or willing to acquire) a basic knowledge of chemistry and interested in how the natural environment operates as a chemical system.

Book excerpt: Volume 17, entitled Lead: Its Effects on Environment and Health of the series Metal Ions in Life Sciences centers on the interrelations between biosystems and lead. The book provides an up-to-date review of the bioinorganic chemistry of this metal and its ions; it covers the biogeochemistry of lead, its use (not only as gasoline additive) and anthropogenic release into the environment, its cycling and speciation in the atmosphere, in waters, soils, and sediments, and also in mammalian organs. The analytical tools to determine and to quantify this toxic element in blood, saliva, urine, hair, etc. are described. The properties of lead(II) complexes formed with amino acids, peptides, proteins (including metallothioneins), nucleobases, nucleotides, nucleic acids, and other ligands of biological relevance are summarized for the solid state and for aqueous solutions as well. All this is important for obtaining a coherent picture on the properties of lead, its effects on plants and toxic actions on mammalian organs. This and more is treated in an authoritative and timely manner in the 16 stimulating chapters of Volume 17, which are written by 36 internationally recognized experts from 13 nations. The impact of this recently again vibrant research area is manifested in nearly 2000 references, over 50 tables and more than 100 illustrations (half in color). Lead: Its Effects on Environment and Health is an essential resource for scientists working in the wide range from material sciences, inorganic biochemistry all the way through to medicine including the clinic ... not forgetting that it also provides excellent information for teaching.
Download or read book Ecological Biochemistry written by Gerd-Joachim Krauss and published by John Wiley & Sons. This book was released on 2015-01-12 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first stand-alone textbook for at least ten years on this increasingly hot topic in times of global climate change and sustainability in ecosystems. Ecological biochemistry refers to the interaction of organisms with their abiotic environment and other organisms by chemical means. Biotic and abiotic factors determine the biochemical flexibility of organisms, which otherwise easily adapt to environmental changes by altering their metabolism. Sessile plants, in particular, have evolved intricate biochemical response mechanisms to fit into a changing environment. This book covers the chemistry behind these interactions, bottom up from the atomic to the system's level. An introductory part explains the physico-chemical basis and biochemical roots of living cells, leading to secondary metabolites as crucial bridges between organisms and the respective ecosystem. The focus then shifts to the biochemical interactions of plants, fungi and bacteria within terrestrial and aquatic ecosystems with the aim of linking biochemical insights to ecological research, also in human-influenced habitats. A section is devoted to methodology, which allows network-based analyses of molecular processes underlying systems phenomena. A companion website offering an extended version of the introductory chapter on Basic Biochemical Roots is available at http://www.wiley.com/go/Krauss/Nies/EcologicalBiochemistry

Available in PDF, EPUB and Kindle. Book excerpt: The book you are just going to read represents the greater part of the papers presented at the International Conference on Industrial and En vironmental Xenobiotics, held in Prague, 1980, and some contributions by those who could not come. The first aim of the meeting was to fol low the tradition set up by the first conference in 1977. Again, we in vited biochemists, pharmacologists, and toxicologists from both East and West, who were involved in the study of disposition, biotransforma tion, and toxicity of important kinds of industrial and environmental pollutants, to promote the exchange of ideas and opinions on priorities in this area of the study of human environment. The invited contributions offer an excellent survey of and pro found insight into specific areas of toxicology and disposition of metals and organic chemicals, and the series of papers on specific subjects bring fresh information on the biotransformation and mechanisms of toxic action of several industrially important solvents tmd monomers of plastics. Rather than from the Preface, the reader should seek guidance from the Index, which clearly shows the overlapping of this area of toxicology with the latest results in biochemistry. We gratefully acknowledge the understanding, care, and preciSion of the publisher that made this book possible.

Download or read book Plant Responses to the Gaseous Environment written by A.R. Wellburn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of air pollution effects on vegetation has made rapid progress in the last five years. Growing concerns about effects of future increases in temperature and carbon dioxide (C0 ) levels on plant life have altered 2 the perspective of plant biologists in the field of pollutant-plant inter actions. In many cases, it is anticipated that crops and trees will increasingly experience multiple stresses in an altered environment: an environment in which physiological processes will no longer be matched to climate. Because of this problem, a major part of the focus of the air pollution effects research has shifted since 1987. Moreover, recent advances in our understanding of plant metabolic and molecular responses to stress have made it clear that many abiotic stresses elicit similar fundamental mechanisms. Adaptation responses to drought, extremes of temperature, xenobiotics and air pollutants are now known to involve the response of both specific and common resistance mechanisms, which often include altered gene expression. The field of air pollution effects on vegetation has benefitted greatly from this unification since results obtained and advances made in allied fields are now directly relevant. The advent of molecular genetics has made possible the production of transgenic plants containing altered amounts of resistance gene products which enables the posing of experimental questions which could not be addressed only five years ago. Hypotheses concerning the relevance of specific metabolites and processes to known responses to air pollution stress can now be tested.

Download or read book Applications of Molecular Biology in Environmental Chemistry written by Roger A. Minear and published by CRC Press. This book was released on 1995-05-04 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: During this century we have experienced a shift in the leading causes of death from infectious diseases, such as pneumonia and influenza, to chronic diseases, such as heart disease and cancer. Whereas infectious diseases are often related to a single infectious agent, chronic diseases are often related to a combination of environmental (including occupational) chemical exposures and genetic factors. This valuable reference helps the reader to identify these chemical pollutants in environmental matrices such as air, water, food, and soil. It provides improved analytical methods to measure the pollutant, its metabolites, and its various possible adducts in humans. This book presents the latest work designed to assess potential exposure (environmental concentration and activity of pollutants), dose to humans, and a molecular basis for some of the affected biological mechanisms.
