Book Description
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 Environ mental 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 environment 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.

Book Description
Pyrolysis of Organic Molecules with Applications to Health and Environmental Issues, the 28th volume in the Techniques and Instrumentation in Analytical Chemistry series, gives a systematic and comprehensive description of pyrolysis of non-polymeric organic molecules. Pyrolysis is involved in many practical applications as well as in many common human activities, but harmful compounds can be generated in the process. The study of pyrolysis and of the formation of undesirable compounds as a result of pyrolytic processes is of considerable interest to chemists, chemical engineers, and toxicologists. - Pyrolysis results for compounds not previously studied or reported - Updated information from a large body of results published on pyrolysis of individual compounds or classes of compounds - Information on mechanisms and kinetics of numerous pyrolytic processes

Book Description
Enzyme inhibitors play a pivotal role in pharmaceutical and nutraceutical industries. The primary understanding of the action of inhibitors helps pharmacologists during the design process for developing new therapeutic drugs. Most drugs treat various chronic and life threatening diseases owing to their specificity and the potency of enzymes which they can inhibit. Enzyme inhibitors are used to screen various levels of diseases which propel the growth of inhibitors. The potential for enzyme inhibitors in the therapeutics market is very high as the biochemical properties and classes of enzyme inhibiting products are readily available. The other broad aspect of enzyme inhibition is their application in analytical sensors. These sensors assist in monitoring various environmental factors. Understanding the mechanism of inhibition and regeneration of enzymes is a general problem of great importance for many biochemists and biotechnologists especially when using immobilized enzymes. This reference compiles applied information about enzyme inhibitors used in medicine and environmental monitoring applications. Chapters presented in this volume cover special topics including biosensors, crop improvements in agriculture, biofuel production, pesticide and heavy metal detection, and drug therapy for human diseases such as breast cancer, neurological diseases and viral infections. The collection of topics in this volume makes it an informative resource for readers at all academic levels on the applications of enzyme inhibitors in medicine and environmental sciences.

Book Description
Chlorinated paraffins are one of the last classes of chlorinated compounds that are still being produced worldwide and used in high quantities in many applications. They are particularly used in cutting oils in the metal industry, but also as lubricants, plasticizers, flame retardants and as additives in adhesives, rubber, paints and sealants. This volume covers the state-of-the-art of methods for the synthesis and analysis of chlorinated paraffins. Experts in the field provide an overview of their worldwide occurrence and utilization and describe their toxicological properties. International regulations and production volumes are presented as well as an example of a risk assessment study that was carried out in Japan. This book is a valuable and comprehensive source of information for environmental scientists interested in the occurrence and toxicology of chlorinated paraffins and for authorities and producers.

Book Description
Disease, injury, or congenital disorders result in an inability to perform activities of daily living as effectively as others. Most of these activities take place within and are dependent upon the designed environment. This book presents the specialized area of person-centered health care design, which focuses on a person's design needs because of one or more health conditions and requires foundational knowledge pertaining to infection control, bio-physiology, neuroscience, and basic biomechanics. Whether the designer has engaged in person- or condition-centered design, this book examines the causes that bring about health conditions, such as autoimmune disorders, chronic lung disease, muscular dystrophy, and neurological disorders, and the effects these have on a person's quality of life. Over forty various health conditions are discussed in relation to assorted building typologies—schools, group homes, rehabilitation and habilitation centers, and more—to identify design solutions for modifying each environment to best accommodate and support a person’s needs. Dak Kopec encourages readers to think critically and deductively about numerous health conditions and how to best design for them. This book provides students and practitioners a foundational framework that supports the promotion of health, safety, and welfare as they pertain to a person's physiological, psychological, and sociological well-being.
