pm-mort -- Release of final report on fine PM-related premature deaths
Posted: 24 Oct 2008 16:32:40
The staff report on fine PM-related premature deaths was released on October 24, 2008. 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 describing the association between PM2.5 and premature death. It also provides an updated threshold level for this relationship. This staff report includes revisions made in response to public comments received by July 11, 2008 on the draft staff report, which was released on May 22, 2008. A supplement to the final report contains all written public comments received. The revisions to the methodology were developed following staff’s review of all relevant scientific literature and two public workshops. The new methodology underwent peer review in January, 2008, by a panel appointed by the University of California, Berkeley. This panel was composed of experts in the fields of epidemiology, air quality measurement, risk management, health effects of air pollution, and biostatistics. Based on the new factor of 10% increase in the risk of premature death per 10 micrograms per cubic meter increase in PM2.5 exposure and an updated threshold value of 5 microgram per cubic meter, staff estimates that exposure to PM2.5 contributes to about 18,000 premature deaths statewide annually (95% confidence interval: 5,600 to 32,000). For pdf copies of the staff report and the supplement, as well as additional information on the public workshops, comments received, and other activities related to updating the health impacts analysis methodology, please see the Web page at: http://www.arb.ca.gov/research/health/pm-mort/pm-mort.htm. References cited in this report are available for public inspection. Paper copies of the staff report and supplement are also available; please contact Dr. Alvaro Alvarado by email at aalvarad@arb.ca.gov or by phone at 916-445-4843 if you would like a copy mailed to you. Questions regarding the effort to update this methodology may be directed to Dr. Hien Tran by email at htran@arb.ca.gov or by phone at 916-445-1324.
