# Hi Rebecca,

I sent the results for the 2008 study in June. I've re-attached the tables, and added 'Franklin 2008

study' to the filename. Perhaps these tables got mi xed up with the 2007 paper results that I sent a

week or two before these ones (according to my reco rds).

Please let me know if you are looking for something else.

Thanks,

Meredith

**Dear Dr. Meredith Franklin,**

**My name is Rebecca Yang and I am writing to you on behalf of Dr. Lindsay Stanek and Ms. Beth**

**Hassett-Sipple of the EPA. On May 2, 2009, an email was sent or forwarded to you requesting**

**descriptive statistics on the air quality distribution data for PM 2.5 and/or PM10-2.5 for your 2007**

**study titled, "Association between PM2.5 and all-cause and specific-cause mortality in 27 US**

**communities." Unfortunately, your 2008 study titled, "PM25 composition & daily mortality in 25**

**US communities," was missing from the May 2nd email request.**

**With your schedule permitting, I would like to speak with you on Friday, October 30th in order to**

**obtain the descriptive statistics for your 2008 study listed below. The statistics of most interest for**

**the 24-hour concentrations of PM2.5 are the following:**

**- 95th percentile**

**- 96th percentile**

**- 97th percentile**

**- 98th percentile**

**- 99th percentile**

**- maximum concentration value**

**In respect for your time, if there is another researcher/co-author who may be able to handle this**

**air quality data request (i.e., has easier access to the data), I would greatly appreciate his/her**

**name and contact information. Please also note that your responses, in addition to any data you**

**provide, will be placed in the EPA's public docket.**

**Thank you so much for your understanding and support! I apologize for the inconvenience but**

**the data you provide is critical for inclusion in the EPA 's Integrated Science Assessment and**

**Policy Assessment Document for Particulate Matter. Please feel free to email me the descriptive**

**statistics at yang** 

**. rebecca**  **@ epa** 

**. gov**  **. Unless I hear from you otherwise, I look forward to speaking**

**with you on Friday, October 30th! Thank you for your time!**
