Citations to information about the 30 morbidity cohort studies









Heidi, 

 

Please find attached a note from Susan Stone that identifies the Annex
to the criteria document which characterizes the 30 morbindity studies
and provides.  Her note also provides directions on how to access the
Annex. Please let me know if you need any further information.  Thanks.

Lydia:  The cohort studies are well-characterized in the Annex of the
Criteria Document, in Table AX7-6, Effects of Chronic O 3  Exposure on
Respiratory Health, which starts on Page AX 7-102.  This annex can be
found on the ozone NAAQS web page on the TTN.  Click on the link to the
CD, and follow those links until you get a choice of Volumes 1, 2 or 3. 
This annex is in Volume 2, and Table AX7-6 can be found in the Table of
Contents. Susan

RE: Response to 2 issues from teleconference with OMB on ozone NAAQS 









Lydia, 

Welcome to 2008!  I hope the folks of RTP enjoyed a satisfying holiday. 

I'm organizing interagency requests for follow up on both Lead and Ozone


and will get back to you/Margaret shortly to schedule a couple of 

meetings.  Fairly high on my priority list is resolving remaining 

concerns around the definition of "baseline" in the Ozone NAAQS RIA, but


I have requests from interagency on other issues as well (Pb NAAQS Risk 

Assessment, for example), and I'll try to narrow the topic areas to make


these meetings respectful and productive use of your team's time. 

In the meantime, I wonder whether characterization of the 30 morbidity 

cohort studies is feasible this week.  I really appreciate your team's 

help, I know you have a great deal on your desks as you prepare for 

option selection. 

Best - 

heidi

Heidi, 

I don't know that we have anyone in on Monday who can work on responding


to your question, but we'll try to answer it by mid-next week.  I hope 

that you and your famliy have a happy, healthy new year.

Thank you, Lydia. 

We understood on our call that the 250 new studies could be summarized 

as follows: 

65 panel studies 

75 Time series - morbidity 

75 Time series - mortality 

 5 Cohort studies - mortality 

30 Cohort studies - morbidity 

If this is correct, could your team provide further characterization of 

group of 30 morbidity cohort studies - which studies are you referring 

to here? 

Thank you; I hope you had a good holiday and a Happy New Year to you and


yours -- 

Heidi

Hi folks, 

Please find Harvey and John's response to two questions you raised in 

our last discussion about the ozone risk and exposure assessments.

Lydia, 

Below are responses to 2 issues/questions raised by OMB.  These can be 

forwarded to OMB. 

1.  Is there anything that the APEX exposure modeling output can tell 

us about the relationship between the distribution of ambient 

concentrations measured at the monitors and the distribution of personal


ozone exposures? 

Response: The exposure modeling performed (APEX) for ozone looked at 

population distributions of exposure for each urban area and did not 

provide information that can address the question raised about the 

ratios of ambient concentrations to personal exposures for individuals 

or populations living around each monitor in the urban area. 

2.  Can you explain the difference between the ratio of 1.33 given in 

the Rochester workgroup report relating 8-hr ozone and 24-hr ozone and 

the ratio of about 2 given in the OAQPS Staff Paper? 

Response:  The ratio discussed on p.35 of the Rochester report relates 

to converting the average of 24-hr averages across all monitors in an 

urban area to the average of 8-hr averages across all monitors in an 

urban area.  In contrast, the ratio of about 2 discussed in the OAQPS 

Staff Paper is relating the average of the 24-hr averages across all 

monitors in an urban area with the 8-hr average at the highest monitor 

within that same urban area.   Clearly, these are two very different 

comparisons which are being done for different purposes.
