title: Respiratory effects of outdoor air pollution.
abstract: Outdoor air pollution adversely affects human health and the quality of the environment. However, epidemiologic studies of these effects are difficult to control because of confounding variables such as age and cigarette smoking and the difficulty in estimating doses of pollutants. Drs Griffith and Levin discuss the relationship between major types of pollutants and increased morbidity and mortality from respiratory disease.
