# Hey Beth: Here's the details on the FP concentrati ons for that study.

Not sure when the OEM coarse particle study is comi ng out. We just

wrote them to check and I'll let you know when we h ear something. b

Bart, thanks again for providing additional air qua lity data to our PM

NAAQS review team. We are also interested in recei ving information

for

one more study that you were the primary author on:

1: Environ Health Perspect. 2009 Mar;117(3):475-80. Epub 2008 Dec 16.

The effects of fine particle components on respirat ory hospital

admissions in children.

Would it be possible to provide additional informat ion on this study

as well?

Also, I haven't been able to find your new coarse P M study on-line.

Do you know if it has been posted yet?

Thanks in advance for your assistance!

Take care,
