Book Description
The focus of this symposium is the technology of nose exposure to rodents and the various kinds of measurements one can make before, during, and after exposure to obtain information about the dose and effects relative to the exposure. However, certain principles of inhalation exposure are common to all inhalation techniques. This introduction provides some historical perspectives in the development of both inhalation chambers and nose exposure techniques. It discusses the major advances in chamber design and nose exposure technology. The accumulation in and removal of test agents from the system is described. Two critical issues in inhalation studies, aerosol and vapor generation and techniques to measure the concentration of the test agents, are beyond the scope of this symposium and are not covered. Contents of volume 9, number 4 include the following topics: Basic Principles of Inhalation Exposure; Measurement of Respiration and Respiratory Responses During Inhalation Exposures; Whole-Body Plethysmography in Sedentary or Exercise Conditions to Determine Pulmonary Toxicity, Including Hypersensitivity Induced by Airborne Toxicant; Modernization of Nose-Only Smoking Machines for Use in Animal Inhalation Studies; An Exhaled Breath Chamber System for Assessing Rates of Metabolism and Rates of Gastrointestinal Absorption with Volatile Compounds; Large-Scale Assessment of Motor Activity in Rodents: Procedures For Routine Use in Toxicology Studies; Two-Stage Carcinogenesis and the Carcinogenecity of Phorbol Myristate Acetate (PMA).

Book Description
This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Book Description
Ignition of upholstered furniture by small open flames from matches, cigarette lighters, and candles is one of the leading causes of residential-fire deaths in the United States. These fires accounted for about 16% of civilian fire deaths in 1996. On average, each year since 1990, about 90 deaths (primarily of children), 440 injuries, and property losses amounting to 50 million dollars have resulted from fires caused by the ignition of upholstered furniture by small open flames. Certain commercial seating products (such as aircraft and bus seats) are subject to flammability standards and sometimes incorporate FR-treated upholstery cover materials, but there is no federal-government requirement for residential upholstered furniture, and it is generally not treated with FR chemicals. It is estimated that less than 0.2% of all U.S. residential upholstery fabric is treated with flame-retardant (FR) chemicals. The Consumer Product Safety Act of 1972 created the U.S. Consumer Product Safety Commission (CPSC) as an independent federal regulatory agency whose mission is to protect the public from unreasonable risks of injury and death associated with consumer products. CPSC also administers the Flammable Fabrics Act, under which it regulates flammability hazards and the Federal Hazardous Substances Act (FHSA), which regulates hazardous substances including chemicals. In 1993, the National Association of State Fire Marshals petitioned CPSC to issue a performance-based flammability standard for upholstered furniture to reduce the risk of residential fires. The Commission granted that portion of the petition relating to small open flame ignition risks. In response to concerns regarding the safety of FR chemicals, Congress, in the fiscal year 1999 appropriations report for CPSC, requested that the National Research Council conduct an independent study of the health risks to consumers posed by exposure to FR chemicals that are likely to be used in residential upholstered furniture to meet a CPSC standard. The National Research Council assigned the project to the Committee on Toxicology (COT) of the Commission on Life Sciences' Board on Environmental Studies and Toxicology. COT convened the Subcommittee on Flame-Retardant Chemicals, which prepared this report. Subcommittee members were chosen for their recognized expertise in toxicology, pharmacology, epidemiology, chemistry, exposure assessment, risk assessment, and biostatistics. Toxicological Risks of Selected Flame-Retardant Chemicals is organized into 18 chapters and two appendices. Chapter 2 describes the risk assessment process used by the subcommittee in determining the risk associated with potential exposure to the various FR chemicals. Chapter 3 describes the method the subcommittee used to measure and estimate the intensity, frequency, extent, and duration of human exposure to FR chemicals. Chapters 4-19 provide the subcommittee's review and assessment of health risks posed by exposure to each of the 16 FR chemicals. Data gaps and research needs are provided at the end of these chapters.

Book Description
The one-stop resource for health protection professionals, environmental scientists and safety engineers. Since the entire 40-volume Ullmann's Encyclopedia is inaccessible to many readers - particularly individuals, smaller companies or institutes - all the information on industrial toxicology, ecotoxicology, process safety as well as occupational health and safety has been condensed into this convenient 2-volume set. Based on the latest online edition of Ullmann's containing articles never been before in print, this ready reference provides practical information on applying the science of toxicology in both the occupational and environmental setting, and explains the fundamentals necessary for an understanding of the effects of chemical hazards on humans and ecosystems. The detailed and meticulously edited articles have been written by renowned experts from industry and academia, and much of the information has been thoroughly revised. Alongside explanations of safety regulations and legal aspects, this set covers food additives, toxic agents as well as medical and therapeutical issues. Top-quality illustrations, clear diagrams and charts combined with an extensive use of tables enhance the presentation and provide a unique level of detail. Deeper insights into any given area of interest is offered by referenced contributions, while rapid access to a particular subject is enhanced by both a keyword and author index.

Book Description
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.
