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

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! 

Pradeep

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).

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!
