BACKGROUND

The California Air Resources Board (CARB) routinely reviews the health effects of air pollutants, revises state ambient air quality standards, and estimates the impacts of air pollutant exposures on public health. On October 24, 2008 the ARB released the staff report titled "Methodology for Estimating Premature Deaths Associated with Long-term Exposure to Fine Airborne Particulate Matter in California." This staff report presents an updated relative risk factor for the association between PM2.5 and premature death. It also provides an updated threshold level for this relationship. The 2008 staff report and other related documents can be found at this site.

At the December 9, 2009 meeting of the ARB, the Board directed staff to reassess the methodology developed to quantify the association between PM2.5 exposure and premature death. The Board also requested that staff convene a symposium to discuss the development of a new methodology for estimating premature deaths.
