Ambient Air: A Complex Mixture from Diverse Sources
Find out about research on diesel exhaust, ozone, particulate matter, and mixtures
HEI supports methods development, including statistical and biological methods
Progress on funded projects is highlighted at the Annual Conference
HEI brings together scientists, policy makers, non-governmental and industry people to exchange ideas and promote high quality science
Since the early 1980s, the core mission of HEI is to study the health effects of air pollution with a focus on vehicular emissions. More recently, the scope has broadened to air pollution in general, because ultimately people are exposed to a mixture of pollutants from different sources. This page provides a gateway to HEI's research on diesel exhaust, mixtures, ozone, statistical methods, and other important topics. The program covers a wide area of research approaches, including epidemiology, toxicology, exposure science, and statistics.
