AR 226_ 0646 PFOS Medical Surveillance/Epi - oL 000023 Internal Correspondence 3am -- EE--------g--------eee-- ree-- -------- August 2000 MemotoFilere: ~~ OUS pooled samples Pursuant to a reviewofmy file, there are raw data for several other pooled human sera sample results for PFOS dating from 1999. This data were assembled in our own 3M. laboratory from European blood banks subsequent to the preparationofthe January 21, 1999 3M document entitled "Perfluorooctane Sufonate: Current Summary of Human Sera, Healthand Toxicology Data." The data are very consistent with that presented in that paper. No formal report was made relative to these data. Itis my understanding that each pool is comprised of 15-20 donors in eachofthree European countries. The results which have been measured in ppb are: 1. Belgium -six pooled samples analyzed; range = (4.9 to 22.2); average = 17 ppb 2. Netherlands - five pooled samples analyzed; range = (39-61); average = 53 ppb. 3. Germany six pooled samples analyzed; range = (3245.6); average = 37 ppb JeffMandel 000U24
