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 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
