Subject: RE: Request for PM AQ data

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

Lyndsey, thank you once again for providing the PM2.5 data for the 3 studies identified in your earlier 

email. 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
