 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
