Chemical Analysis

www.ebooks.com/cj.asp?IID=1838806&cjsku=1838806...
River Pollution 1: Chemical Analysis discusses methods of detecting and determining the various forms of pollution and the interpretation of results. It aims to provide a chemical background for, and supplement to, the information on analytical methods, and to review critically other methods which may be useful in certain circumstances for research, control work, and field tests. The book begins with a description of river surveys, and physical and chemical methods for determining river pollution. Separate chapters cover methods to determine the presence of dissolved oxygen, combined nitrogen, sulfur compounds, carbon dioxide, free chlorine, metallic contaminants, and carbon compounds. Subsequent chapters discuss the estimation of less important substances which may sometimes be encountered in pollution problems; and the significance of chemical and physical tests and the interpretation of the results of an analysis. This book is intended for those interested in chemical analysis as applied to river pollution problems, sewage, and trade wastes.

Chemical Transformations of Polymers

www.ebooks.com/cj.asp?IID=1837686&cjsku=1837686...
Chemical Transformations of Polymers provides information pertinent to the fundamental structure and aspects of the chemical transformation of polymers. This book examines several experiments for the chemical transformation of polymers, which start from the assumption that the reactivity of a functional group in a macromolecule has to be similar as one in a low molecular compound. Organized into 19 chapters, this book begins with an overview of the various photochromic systems that have been used in polymer chemistry. This text then examines the three types of stable polymers with unpaired electrons, including polyradical ions, neutral polyradicals, and polymeric charge transfer complexes. Other chapters consider the kinetic laws and traits of migration mechanisms of free valence in the process of decay of free radicals in polymers. The final chapter deals with the complicated reaction of the degradation of polymers induced by the presence of metal compounds. This book is a valuable resource for chemists, scientists, and physiochemical researchers.

The Chemical Muse

www.ebooks.com/cj.asp?IID=1764594&cjsku=1764594...
"The last wild frontier of classical studies." ---The Times (UK) The Chemical Muse uncovers decades of misdirection and obfuscation to reveal the history of widespread drug use in Ancient Rome and Greece. In the city-states that gave birth to Western civilization, drugs were an everyday element of a free society. Often they were not just available, but vitally necessary for use in medicine, religious ceremonies, and war campaigns. Their proponents and users existed in all classes, from the common soldier to the emperor himself. Citing examples in myths, medicine, and literature, D. C. A. Hillman shows how drugs have influenced and inspired the artists, philosophers, and even politicians whose ideas have formed the basis for civilization as we know it. Many of these ancient texts may seem well-known, but Hillman shows how timid, prudish translations have left scholars and readers in the dark about the reality of drug use in the Classical world. Hillman's argument is not simply "pro-drug." Instead, he appeals for an intellectual honesty that acknowledges the use of drugs in ancient societies despite today's conflicting social mores. In the modern world, where academia and university life are often politically charged, The Chemical Muse offers a unique and long overdue perspective on the contentious topic of drug use and the freedom of thought.

Cleaning Up the Environment

www.ebooks.com/cj.asp?IID=457025&cjsku=457025...
The industrial might of the United States grew in the 1930s and flourished during the two world wars. As businesses large and small supplied the needs of the country, they discarded their wastes in landfills, pits, and waterways. It was an easy and inexpensive way to get rid of wastes before more were made. Waste dumping had not yet been linked with illnesses so few people worried about it, especially if the materials were hidden under the ground or in the ocean. Within 20 years of the end of WWII, those wastes began to cause serious health problems. Featuring full-color photographs and line illustrations, "Cleaning Up the Environment" explores current and emerging methods in pollution cleanup. Hazardous wastes are removed from contaminated places by physical, chemical, or biological methods, and these methods are described here as well as their advantages and disadvantages. This new book takes readers through the entire step-by-step process of finding, testing, and cleaning up hazardous waste sites, beginning with contamination assessment and ending with a cleaned and restored body of land or water. Chapters of this book include: Measuring Contamination; Excavation of Contaminated Sites; Microbes and Plants for Toxic Cleanup; Oxidation Technology; Brownfield Sites; Remediating the Water Supply; and, Superfund Sites.
