A comprehensive survey of the epidemiology of common environmental exposures, this volume covers diet, water, particulates in outdoor air, nitrogen dioxide, ozone, environmental tobacco smoke, radon in homes, electromagnetic fields, and lead. Design and analysis issues, risk assessment and meta-analysis, and future directions in environmental epidemiology are also discussed. All chapters provide a review of the relevant literature as well as an overview of important methodologic issues, particularly exposure assessment and statistical methods. Most of these exposures are widespread and low-level, and are thought to increase the risk of chronic diseases that have many causes. Even though the disease risks due to these exposures may be low, the public health burden may be significant because large numbers of people are exposed. Such exposures are inherently difficult to detect via observational epidemiology. This book clarifies the problems and suggests ways to move forward. It will be useful to students and practitioners of public health, environmental health, and epidemiology.
