Dear 8(e) Coordinator : Re: Perfluorooctanoate Anion (PFOA) - Updated Occupational Serum Sample Results
Villers Saint Paul, France - Telomers Production
This letter is a supplement to our letter of March 27, 2006 which included serum sampling results from the Villers Saint Paul, France facility among other facilities. The updated serum sampling results for workers at the above referenced DuPont site are for 2008. The levels ofPFOA reported with this submission are generally corroborative of previously reported levels in an occupational setting . This information is provided to the TSCA 8(e) office in view of the Agency's continued interest in perfluorinated substances and as precautionary measure . Sincerely,
A. Michael Kaplan, Ph.D. Director - Regulatory Affairs
