Behavioral Measures of Neurotoxicity


Book Description

Exposure to toxic chemicalsâ€"in the workplace and at homeâ€"is increasing every day. Human behavior can be affected by such exposure and can give important clues that a person or population is in danger. If we can understand the mechanisms of these changes, we can develop better ways of testing for toxic chemical exposure and, most important, better prevention programs. This volume explores the emerging field of neurobehavioral toxicology and the potential of behavior studies as a noninvasive and economical means for risk assessment and monitoring. Pioneers in this field explore its promise for detecting environmental toxins, protecting us from exposure, and treating those who are exposed.




Environmental Neurotoxicology


Book Description

Scientists agree that exposure to toxic agents in the environment can cause neurological and psychiatric illnesses ranging from headaches and depression to syndromes resembling parkinsonism. It can even result in death at high exposure levels. The emergence of subclinical neurotoxicity-the concept that long-term impairments can escape clinical detection-makes the need for risk assessment even more critical. This volume paves the way toward definitive solutions, presenting the current consensus on risk assessment and environmental toxicants and offering specific recommendations. The book covers: The biologic basis of neurotoxicity. Progress in the application of biologic markers. Reviews of a wide range of in vitro and in vivo testing techniques. The use of surveillance and epidemiology to identify neurotoxic hazards that escape premarket screening. Research needs. This volume will be an important resource for policymakers, health specialists, researchers, and students.

Introduction to Neurobehavioral Toxicology


Book Description

Introduction to Neurobehavioral Toxicology: Food and Environment examines the effects of chemicals on the central and peripheral nervous system and the subsequent changes in behavior, with a focus on the toxicity of food components and behavioral effects of environmental toxicants. Topics addressed include acute and chronic effects; reversible and




Drugs of Abuse and Addiction


Book Description

Drugs of Abuse and Addiction: Neurobehavioral Toxicology examines drugs of abuse and addiction and how they affect behavior. This book considers the entire range of addiction research in humans and animals, using a multidisciplinary approach to discuss all areas of the neuro- and behavioral sciences involved. Emphasis is on acute and chronic effect




Behavioral Toxicology


Book Description

Behavioral toxicology is a young discipline in the United States; so young, in fact, that this is one of its first books. Behavioral questions are bound to play a major role in future scientific work and governmental decisions involving the health effects of environmental contaminants and other chemicals. This role springs from two key problems that face scientists and public agencies required to set acceptable exposure standards or to determine criteria for the toxicity of therapeutic chemicals: How do you evaluate effects that may show up only as subtle functional disturbances? And how do you de tect toxic effects early enough so that they may still be reversible, before they produce major damage? The contributions in this book come from a collection of scientists whose interests span a wide variety of problem areas. The focus is largely on me thodological issues because they represent the most immediate concern of the discipline. We expect that this collection of papers will represent a useful source book for behavioral toxicology for some time. For the past few years, the University of Rochester's Department of Radiation Biology and Biophysics has sponsored a series of international conferences on chemical toxicity, partly as a response to concern over the con sequences to health of the rich chemical soup in which we live. This book is based upon presentations made to the fifth of the series. Held in June, 1972, it was the first formal meeting devoted to behavioral toxicology in this country.







Toxicological Effects of Methylmercury


Book Description

Mercury is widespread in our environment. Methylmercury, one organic form of mercury, can accumulate up the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Combustion processes, especially coal-fired power plants, are major sources of mercury contamination in the environment. The U.S. Environmental Protection Agency (EPA) is considering regulating mercury emissions from those plants. Toxicological Effects of Methylmercury reviews the health effects of methylmercury and discusses the estimation of mercury exposure from measured biomarkers, how differences between individuals affect mercury toxicity, and appropriate statistical methods for analysis of the data and thoroughly compares the epidemiological studies available on methylmercury. Included are discussions of current mercury levels on public health and a delineation of the scientific aspects and policy decisions involved in the regulation of mercury. This report is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report also provides an excellent example of the implications of decisions in the risk assessment process for a larger audience.




Neurobehavioral Toxicology: Peripheral nervous system


Book Description

This book, the first of three volumes, provides a thorough background to the emerging field of neurobehavioral toxicology by looking at current clinical approaches and tests, as well as assessing current clinical research. The analysis of the impact of toxins on the human nervous system is particularly pertinent given the ongoing expansion of pharmaceuticals, industrial hazards, biological warfare and global pollution. A comprehensive introduction to neurobehavioral toxicology, this work will be of interest to practicing neurologists and neuropsychologists, as well as to occupational medicine physicians and medical toxicologists.




Toxic Effects of Mercury


Book Description

Mercury is widespread in our environment. Methylmercury, an organic form of mercury, can accumulate in the aquatic food chain and lead to high concentrations in predatory fish. When consumed by humans, contaminated fish represent a public health risk. Toxic Effects of Mercury intends to facilitate among its readers the understanding of the importance of mercury pollution in the environment and the health consequences associated with exposure to this metal. The knowledge on methylmercury (MeHg) toxicity collected over the years is undoubtedly robust creating an impression all that is to be learnt about this metal has already been accomplished. However, in large measure, past knowledge has merely laid the ground for interesting questions that have yet to be fully addressed and concepts have yet to be deciphered. One of my major goals was to make a valiant attempt to include state-of-the-art information on the mechanisms of mercury toxicity, describing its effects on cultured cellular systems as well as in whole living organisms, starting from the lessons learned from the tragic events in Minamata Bay, Japan. A special focus of the book is on the neurotoxic effects of MeHg. An understanding at the cellular level is necessary to gather information on the structural and functional alterations induced by MeHg and how they possibly become unmasked and evident at the behavioral level, 32 chapters of the book have been organised having these considerations in mind. This book will provide state-of-the-art information to the graduate students training in toxicology, risk assessors, researchers and medical providers at large. It is aimed to bring the readers updated information on contemporary issues associated with exposure to methylmercury, from its effects on stem cells and neurons to population studies. It is a valuable resource for individuals interested in the public health effects and regulation of mercury. The report provides an excellent example of the implications of decisions in the risk assessment process for a larger audience and is written with the hope that the information will provide better understanding of the mercury problems which confront us.
