Health studies indicate important associations between air pollutants and human health effects. However, there is scientific uncertainty about which individual components of pollutants are related to adverse health effects or how these components interact with other air pollutants. Particulate Matter, for example, is composed of hundreds of individual components and there is growing scientific consensus that not all of these components are equally toxic.
EPRI addresses key scientific uncertainties to determine which components are associated with health effects, and our efforts generate information to support health risk estimates of these components. Our research also seeks to identify the true causative agents, and the sources of those agents, affecting human health and the environment.
