Available in PDF, EPUB and Kindle. Book excerpt: Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environmental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environ ment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over 'five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities of waste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.

Available in PDF, EPUB and Kindle. Book excerpt: The most recent volume in the Drinking Water and Health series contains the results of a two-part study on the toxicity of drinking water contaminants. The first part examines current practices in risk assessment, identifies new noncancerous toxic responses to chemicals found in drinking water, and discusses the use of pharmacokinetic data to estimate the delivered dose and response. The second part of the book provides risk assessments for 14 specific compounds, 9 presented here for the first time.

Download or read book Biochemistry of the Essential Ultratrace Elements written by Earl Frieden and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: The remarkable development of molecular biology has had its counterpart in an impressive growth of a segment of biology that might be described as atomic biology. The past several decades have witnessed an explosive growth in our knowledge of the many elements that are essential for life and maintenance of plants and animals. These essential elements include the bulk elements (hydro gen, carbon, nitrogen, oxygen, and sulfur), the macrominerals (sodium, potas sium, calcium, magnesium, chloride, and phosphorus), and the trace elements. This last group includes the ultra trace elements and iron, zinc, and copper. Only the ultratrace elements are featured in this book. Iron has attracted so much research that two volumes are devoted to this metal-The Biochemistry of Non-Heme Iron by A. Bezkoravainy, Plenum Press, 1980, and The Biochemistry of Heme Iron (in preparation). Copper and zinc are also represented by a separate volume in this series. The present volume begins with a discussion of essentiality as applied to the elements and a survey of the entire spectrum of possible required elements.

Download or read book Manganese in Metabolism and Enzyme Function written by Vern L. Schramm and published by Elsevier. This book was released on 2012-12-02 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manganese in Metabolism and Enzyme Function provides an understanding of the various biological roles of the trace levels of manganese found in mammalian systems. This text discusses the nutritional aspects of manganese in mammals. This book is organized into three sections encompassing 19 chapters. Section I discusses the effects of manganese deficiency, including abnormal pancreatic action and reduced pancreatic manganese in humans and laboratory animals. This text considers the criteria for adding manganese to infant formulas that are commercially available. Section II explores the effects of Mn(II) in protein kinases, protein phosphatases, and other enzymes. The reader is introduced to the electron paramagnetic resonance spectroscopic probes of manganese function. Other chapters discuss the extrinsic tag technique used to study the bioavailability of trace elements, such as iron and zinc. Finally, Section III examines the biophysical, biochemical, and physiological properties and uses of manganese. Nutritionists, toxicologists, scientists, and researchers will find this book extremely useful.

Download or read book Inorganic Species Part 1 written by Roger Minear and published by Elsevier. This book was released on 2012-12-02 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inorganic Species, Part 1 separately considers the various inorganic and organic components that occur in water. While this separation is traditional, it does provide some distinct organizational advantages. This is important because of the wide-ranging audience likely to be using these works. Both practicing professionals and students in environmentally related disciplines will find these volumes to be a useful reference source. This book comprises six chapters, and begins with a focus on the origin and nature of selected inorganic constituents in natural waters. Succeeding chapters go on to discuss redox potential, which discusses its measurement and importance in water systems; alkalinity and acidity; conductance, which is defined here as a collective measure of dissolved ions; the theory and measurement of turbidity and residue; and, finally, a summary of methods for water-quality analysis of specific species. This book will be of interest to practitioners in the fields of geology and environmental engineering.
