Hi Beth,
Paige Tolbert forwarded me the email below. I am re-sending the requested data from the following studies:

Tolbert et al., 2007 Metzger et al., 2004 Peel et al., 2005
However, you should already have these. After receiving the PM2.5 statistics you followed up with a request for the PM2.5-10 statistics from Tolbert et al., 2007 which I sent also sent previously and is again attached.
Let me know if we are missing something...

Thanks, Lyndsey**To :**  **Cc: Bcc:**  **Subject: Darrow Tolbert**  **- Response to Coarse PM Data Request July 23**

Lyndsey, thank you once again for providing the PM2.5 data for the 3 studies identified in your earlier
em ail. We are also interested in obtaining additional air quality data for PM10-2.5. Would it be possible for you to send additional information on the PM10-2.5 measurements used in the Tolbert et al 2007 study?

Thanks in advance for your assistance. Please feel free to call me if you have any questions.

Regards,

Beth
