Book Description
After three decades of research, neurobehavioral toxicity is now acknowledged as a significant outcome of chemical exposure. Its health and economic costs may exceed those by cancer by substantial amounts. This new perspective has been accompanied by efforts designed to explore the responsible mechanisms, to design applicable risk assessment procedures, and to determine the consequent policy implications. This publication includes 25 papers from international experts and includes: human neurobehavioral toxicity; animal behavioral methods; selected model compounds; and risk assessment.

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.

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.

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.

Book Description
Many European Union Directives seek to minimize the potential for harm to humans and the environment arising from the use of chemicals. This book takes an interdisciplinary, selective look at the effector mechanisms employed in such directives. It covers the pre-marketing use of toxicology to identify the hazardous properties of chemicals, acknowledging its shortcomings, while contrasting the scientific method with the precautionary principle in developing risk-management practices. The book then goes on to describe the use of bio-indicators, chemical analyses and mathematical modelling for prediction, or to determine the adequacy of chemical safety legislation. The environmental risk assessment of priority chemicals is described and the impact of pesticides on sustainability in agriculture is discussed from the differing standpoints of agronomy and economics. Audience: All professionals concerned with the safe management of chemicals and their use, including teachers, practitioners, policy makers or legislators.

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.

Book Description
Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.
