Actions to Update Methodology to Estimate Premature Death
Associated with Fine Airborne Particulate (PM2.5) Exposures


August 21, 2006

The ARB staff held a public workshop which discussed an approach for revising the methodology for estimating premature death associated with fine airborne particulate (PM2.5) exposures. Staff focused on assessing the results of health studies that relate changes in PM2.5 exposures to premature death, and how that information may change the concentration-response factor that ARB staff applies in our health impacts analyses. Staff discussed a timeline for completing this work and provided time to respond to questions and comments. The presentations given at the workshop are listed below. Follow this link to view the summary of the public comments.

We expect a draft revised methodology will be available to the public in fall 2006. The draft revised methodology will also undergo a formal peer review by experts in the field. Based on the results of the peer review and public comments, staff will revise the methodology report before updating the Board.
