Dear Pradeep,

I apologize for the delay, I attach an excel table with the number of deaths for each city across the study period. it also includes the number of days with PM2.5 and PM coarse. Please let me know if this is what you needed

thank you Antonella

>>> 08/31/10 4:31 PM >>> Dear. Zanobetti,

We are planning to release the Final Policy Assessment document for the current PM NAAQS review at the end of September. Therefore, to include an analysis of this data in the Policy Assessment we need this data

as soon as possible.

My apologies for the late notice for this request, but please try

...provide us with this information (i.e. county specific number of study participants for each county across the entire study period of 1999-2005) earlier in the month if at all possible.

Thanks!

Dear Dr. Zanobetti,

In our continuing review of the US PM standards, we were asked by

our CASAC to consider how the findings of epidemiological studies might be used in considering a range of levels for a NAAQS. As part of this effort they have encouraged us to consider information on the concentrations that were most influential in generating the health effect estimates reported in individual studies.

Consequently, we are interested in examining the distribution of PM2.5 concentrations in conjunction with the number of study participants included in your published study “The effect of fine and coarse particulate air pollution on mortality: A national analysis”.

Specifically, if available, we interested in receiving from you the county-specific number of study participants for each of the counties included in your analysis across the entire study time period (1999-2005). Page 3 of 4

...We anticipate that this information would provide us with an understanding of the distribution of PM2.5 concentrations linked with your study population and therefore an indication of which PM2.5 concentrations are likely to be most influential in generating the reported health effect estimates.

Thanks in advance for your help!
