**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.**

Villeneuve/HC-SC/ GC/CA To Li Chen/HC-SC/GC /CA@HWC 2009-10-29 10:23 cc AM Yang.Rebecca@epa mail.epa.gov Subject Request for PM A ir Quality Data

Dear Li

The US EPA would like some additional data related to the particulate pollution measures used in our Edmonton stroke stud y that we published a few years ago.

Can you please forward to Rebecca Yang, and CC me t he 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 mea sures and provided them the related output, they could easily extract the v alues that they need.

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

Thanks

Paul
