arbcombo -- Public Workshop on June 25, 2008 to Discuss the Draft Revised Methodology of Estimating PM2.5-Related Premature Deaths

Posted: 06 Jun 2008 16:07:02
At the May 22, 2008 Air Resources Board meeting, staff released a
draft report on the revised methodology for estimating premature
death associated with long-term exposure to fine airborne
particulate matter (Fine PM) in California.  This new
methodology and results will be discussed in detail at a public
workshop on:

June 25, 2008
10:00 am to 12:00 noon
Sierra Hearing Room (2^nd  floor), Cal/EPA Headquarters
1001 I Street, Sacramento, CA

In the draft methodology, staff has incorporated new health
information that relates changes in PM2.5 exposures to premature
death and developed a new relative risk of a 10% increase in
premature death per 10 mg/m3  increase in exposure. Staff also
recommended that a range of 7 mg/m3  to 2.5 mg/m3  be used as
the lowest level of PM2.5 that can be associated with the
increased risk. In the report, staff also updated the ambient
air quality database to years 2004-2006. The draft methodology
has undergone peer review by a panel formed by the University of
California, Berkeley. Details regarding the new methodology can
be found in the staff report titled “Methodology for Estimating
Premature Deaths Associated with Long-Term Exposures to Fine
Airborne Particulate Matter in California, Draft Staff Report,
May 22, 2008”, which can be downloaded from this website:
