Sorry, but this is not possible.

I think you'll have to make do with what I provided you already.

Dear Dr. Villeneuve,

Thank you for your responsiveness despite your busy schedule . It would be great if the 2003 data could 

be provided to us by Nov 13th, but we understand if this request is difficult and/or time-consuming to fulfill. 

Again, I apologize for the inconvenience but thank you for your help thus far. Thank you for your time and 

have a good day!

It will be some time before we can provide the other data. This was data I worked on many years ago 

while at the University of Ottawa.

To re-generate the data will take some time, and my analysts have other pressing things to take care of 
over the next few weeks.

Paul

Dear Dr. Villeneuve, 

Thank you so much for providing the exposure metrics for your 2006 study! I look forward to receiving the 

air quality data for your 2003 study as well. Thank you again!

 Request for PM Air Quality Data 

 

Dear Li

The US EPA would like some additional data related to the particulate

pollution measures used in our Edmonton stroke study that we published a

few years ago.

Can you please forward to Rebecca Yang, and CC me the exposure metrics

listed below (for PM2.5 and PM10).

- 95th percentile

- 96th percentile

- 97th percentile

- 98th percentile

- 99th percentile

- maximum concentration value

I think if you simply ran a PROC FREQ on the PM measures and provided them

the related output, they could easily extract the values that they need.

If you have any questions you can call me at home (613) 729-5447.

Thanks

Paul
