Exposure to toxic chemicalsin the workplace and at homeis 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.
