Subject: Request for additional information on Chiodo et al. (2004)

Dear Dr. Chiodo,

As you may be aware, EPA is currently in the process of reviewing the

U.S. National Ambient Air Quality Standard for Lead and will be

announcing the proposed rule in April/May 2008. The Air Quality Criteria

Document for Lead discusses your 2004 paper as one that showed

statistically significant associations in children at blood lead levels

below 10 ug/dL.  In addition, you also observed statistically

significant associations at blood lead levels below 3 ug/dL.  Would you

be able to provide us with some information regarding the distribution

(e.g., mean, SD, range) of the blood lead levels and number of children

in each of the subgroups  (i.e., less than 10 ug/dL, less than 7.5

ug/dL, less than 5 ug/dL, and less than 3 ug/dL)?

The Pb NAAQS review is on a very tight court-ordered deadline.  We would

greatly appreciate your prompt response.

Sincerely yours,

Jee Young Kim, Sc.D.
