Toxicity Assessment Alternatives: Methods, Issues, Opportunities contains a broad array of critical surveys, contributed by active and respected investigators, describing their research and offering updates on toxicity assessment alternatives, directions determined by current and future grant programs, opportunities for mechanistically based test methods to detect endocrine disruptor activity, the use of alternatives in the Department of Defense hazard assessment initiatives, and the issues and opportunities for validation and regulatory acceptance. Several of these advances make use oftransgenic models that reduce the time and cost of carcinogenicity testing. Others use tissue cultures for the assessment of endocrine disrupting chemicals. Cultures of human epidermal keratinocytes are applicable as models for sulfur mustard lesions, and in vitro protein denaturation is used as a chemical test for assessing the ocular and dermal irritation potential of cosmetic prod ucts. Molecular modeling is applied to explaining chemical toxicity. Commercially developed assay systems have undergone extensive evaluation by their manufacturers. Some of these await external valida tion, and others await acceptance by North American and European regulatory agencies. Toxicity Assessment Alternatives: Methods, Issues, Opportunities provides information from members of the scientific and regulatory communities on what has been achieved and what has been accepted in alternatives to animal testing."

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.

This volume collates articles investigating antioxidant, oxidant and free radical research. It examines the role of such research in health and disease, particulary with respect to developing greater understanding about the many interactions between oxidants and antioxidants, and how such substances may act as natural protectants and /or natural toxicants.

Bringing together the recent and relevant contributions of over 125 scientists from industry, government, and academia in North America and Western Europe, Alternative Toxicological Methods explores the development and validation of replacement, reduction, and refinement alternatives (the 3Rs) to animal testing. Internationally recognized scientists present what has been accomplished thus far in developing acceptable alternatives to traditional animal toxicological assessment and provide potentially new initiatives.

In over 40 chapters, the book addresses 7 themes, beginning with the validation and regulatory acceptance of alternatives in the US, the UK, and Western Europe. Then the book covers methods based on the mechanisms of eye irritation at the ocular surface, dermal toxicity testing, and assessing neurotoxicity. It also includes a case study in the use of alternatives to determine the mechanism of sulfur mustard action and discusses the role of transgenics and toxicokinetics in the development of alternative toxicity tests. Finally the book presents recent innovations in alternatives, including the use of archival data, and in silico techniques.

Focusing on the science and not the politics, Alternative Toxicological Methods concisely discusses the application of state-of-the-art methods and explores cutting-edge research related to developing and validating alternatives to animal testing. This book will benefit toxicologists, cosmetic chemists, pharmacologists, experimental biologists, dermatologists, ophthalmologists, and regulatory officers in their quest for applying the 3Rs to the use of animals in toxicological testing of drug candidates, chemicals, and cosmetics.

The first edition of this book, Chemical Warfare Agents: Toxicity at Low Levels, was published just prior to the terrorist attacks of September 11, 2001. The second edition titled, Chemical Warfare Agents: Pharmacology, Toxicology, and Therapeutics, included new epidemiological and clinical studies of exposed or potentially exposed populations; new treatment concepts and products; improved organization of the national response apparatus addressing the potential for CWA terrorism; and improved diagnostic tests that enable rapid diagnosis and treatment. Since the second edition, the chemical warfare agent community has worked hard to advance research for protection and treatment and develop/improve response approaches for individuals and definitive care. Consequently, in addition to updating previous chapters, Chemical Warfare Agents: Biomedical and Psychological Effects, Medical Countermeasures, and Emergency Response, Third Edition features several new chapters that address the Syrian War, chemical destruction, the Organisation for the Prohibition of Chemical Weapons, biomarkers for chemical warfare agent exposure, field sensors, aircraft decontamination, lung/human on a chip, chemical warfare response decision making, and other research advancements. Features: Describes the newest medical interventions, and the latest technologies deployed in the field, as well as developments in the international response to CW usage highlighting recent events in the Middle East Discusses the latest in organizational/interagency partitioning in terms of responsibilities for emergency response, not just in the United States but at the international level-whether prevention, mitigation, medical care, reclamation, or medico-legal aspects of such response Contains the most current research from bench-level experts The third edition contains the most up-to-date and comprehensive coverage of the question of chemical warfare agent employment on the battlefield or in terrorism. Edited by workers that have been in the field for 35+ years, it remains faithful to the scientific "constants," while evaluating and crediting the advances by the industry that have made us safer.

Toxicology is an integral part of the risk assessment process.
In this book, investigators from the scientific and regulatory communities describe recent technical developments in risk assessment embracing toxicology and its allied sciences, risk qualification and characterisation, risk management, and risk communication.
Case studies pertaining to current issues involving chemical and environmental risks, including military and industrial scenarios, are presented.
Chapters describe value and ethical choices underlying toxicological decisions, economic and legal implications of regulations, understanding risk, and recommendations of the commission on risk assessment and risk management.

Aerobiology is the study of airborne organic particulates in the environment, such as bacteria or fungal spores. These can be either naturally occurring or artificially introduced into the air. Some of the toxicological, pharmacological, and physiological effects of bioaerosols include infections, allergies, and cancer. Research efforts in aerobiology range from remediating household mould to combating bioterrorism. This book focusses on the toxicological aspects of aerobiology, considering the adverse health effects associated with the inhalation of specific bioaerosols, such as anthrax and ricin. Additionally, chapters cover techniques for generating, sampling and characterizing airborne biological materials as well as methods for establishing standards of exposure. Moreover, mitigation of exposure and protection against exposure are described. Bringing together the contemporary status of information in the area, this book will be a valuable reference book for pulmonary specialists, general practitioners of medicine, public health and public safety officers, first responders, military personnel, and students studying toxicology and related disciplines.
