Methods In Inhalation Toxicology

Conducting studies of natural and man-made air contaminants is a specialized research activity that draws upon skills from a variety of disciplines including toxicology, pharmacology, industrial hygiene, and environmental health. Methods in Inhalation Toxicology describes how knowledge from these disciplines is integrated into the design and conduct of inhalation studies. Each of the vital aspects of conducting these studies is discussed in detail, including the use of animal subjects and the related quality control and ethical considerations, air purification methodology, exposure atmosphere generation and characterization, inhalation exposure systems, and real-time and post-exposure biological assessments. These methods will enable you to conduct inhalation studies, easily adding any specific measures of particular interest to your research. The book covers techniques needed to: provide suitable clean air for experiments correctly generate the particles and gases being studied select the proper exposure system monitor the exposure prepare tissues for study ensure that animals do not have confounding lung disease The helpful descriptions and detailed lists of suppliers of preferred equipment and materials will help you to perform valid, reproducible inhalation toxicology studies. Methods in Inhalation Toxicology is a perfect textbook for students in toxicology programs, as well as for scientists who conduct inhalation studies in both academic and industrial environments.

This book focuses on an important aspect of the methods in laboratory animal inhalation toxicology. It is targeted to students in toxicology programs and scientists contemplating performing inhalation studies.

Written by internationally recognized scientists from academic, industrial, and governmental sectors, Inhalation Toxicology, Second Edition details the methods and materials used in the theoretical and applied aspects of inhalation toxicology. The editors emphasize the relationship between the respiratory system and toxicology of inhaled substances

Written by internationally recognized scientists from academic, industrial, and governmental sectors, Inhalation Toxicology, Second Edition details the methods and materials used in the theoretical and applied aspects of inhalation toxicology. The editors emphasize the relationship between the respiratory system and toxicology of inhaled substances and examine methods and measurements for improving our understanding of the basic mechanisms of effects. The book delineates key issues in the field such as regulatory aspects of exposure and testing, testing equipment and methods, biomarkers, pathology, allergies and immunology, irritation of the respiratory tract, and risk assessment. It covers the inhalation of bioaerosols and toxins, ranging from anthrax to household molds as well as genomics, proteomics, and low-level exposure toxicants such as tobacco smoke and chemical warfare agents. Highlights include coverage of the Acute Exposure Guidelines and Emergence Response Guidelines and recent changes in the European and American guidelines for testing procedures. The book focuses on key issues associated with airborne substances and provides critical reviews of the latest advances. Presenting sophisticated concepts in a readable, accessible format, the book distills the latest information into practical knowledge.

The International Life Sciences Institute (ILSI), a nonprofit, public foundation, was established in 1978 to advance the sciences of nutrition, toxicology, and food safety. ILSI promotes the resolution of health and safety issues in these areas by sponsoring research, conferences, publications, and educational programs. Through ILSI's programs, scientists from government, academia, and industry unite their efforts to resolve issues of critical importance to the public. As part of its commitment to understanding and resolving health and safety issues, ILSI is pleased to sponsor this series of monographs that consolidates new scientific knowledge, defines research needs, and provides a background for the effective application of scientific advances in toxicology and food safety.

This book deals with the methods and scientific basis of inhalation toxicology. It describes devices and facilities needed to expose animals to inhaled particles and gases as well as approaches to estimating or measuring the fraction of the inhaled material that is retained in the respiratory tract. The book then reviews the evergrowing repertoire of techniques that can be used to measure the responses elicited by the exposure. Quantitative and qualitative anatomical, physiological, and biochemical strategies are discussed in detail. We believe that the toxicology of inhaled materials is an important and timely topic for several'reasons. During the past decade, morbidity and mortality attributable to cardiovascular disease have significantly decreased. Progress in combatting cancer, the second most important cause of death, has been slower, and lung cancer actually became the leading cause of death in men and the second leading cause of cancer death in women. In addition, the incidence of non-neo plastic respiratory diseases such as emphysema, fibrosis, and chronic bronchitis has increased the past decade. In the United States, the National Institutes of Health (NIH) has recently reported that chronic obstructive pulmonary disease affects nearly 10 miliion persons and accounts for 59,000 deaths yearly; indeed, it ranks as the fifth leading cause of death. Because the incidence is increasing, the NIH estimates that it may become the nation's fourth or even third leading cause of death by the year 2000.

The lungs provide a significant opportunity for the introduction of both therapeutic and toxic chemicals into the human body. In occupational and domestic environments, hazardous chemicals can enter the body through the lungs via gases, aerosols, and particulates from natural and anthropogenic sources. Fully updated with new research and discoveries since the last edition, Inhalation Toxicology, Third Edition presents contributions from internationally recognized scientists in the academic, commercial/industrial, and governmental sectors. A pragmatic resource for practicing professionals and students, the book comprehensively examines the relationship between the respiratory system and the toxicology of inhaled substances. Topics include: Regulatory aspects of exposure and testing Testing equipment and procedures Respiratory allergy and irritation of the respiratory tract Risk assessment Toxicology theory Toxicology modeling Toxic effects of some individual toxicants New topics in this third edition include collection and characterization of airborne particulate matter, the inhalation toxicology of asbestos fibers and nanoparticles, and the development of lung-on-a-chip technology for predicting in vivo responses. Each chapter concludes with thought-provoking questions and answers, enhancing the book’s educational utility.
