East Metro PFC Biomonitoring Pilot Project
Information on this page:
The 2008 East Metro Perfluorochemical (PFC) Biomonitoring Pilot Project was conducted to measure perfluorochemicals (PFCs) in the blood of East Metro residents known to have been exposed to PFCs through drinking water. Past disposal of PFC-containing waste was discovered to have contaminated ground water in these communities.
Participants included 196 adults who lived in Oakdale, Lake Elmo, and Cottage Grove, Minnesota. The MDH Public Health Laboratory tested participants' blood for seven PFCs: perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), perfluorohexane sulfonate (PFHxS), perfluorobutanoic acid (PFBA), perfluorobutane sulfonate (PFBS), perfluorohexanoic acid (PFHxA), and perfluoropentanoic acid (PFPeA).
Three PFCs (PFOA, PFOS, and PFHxS) were found in the blood of all participants. Levels of each were somewhat higher than those found in the U.S. population, but comparable or lower than levels found in other studies of communities exposed to PFCs in drinking water. Two PFCs (PFBA and PFBS) were found in a smaller proportion of participants, and two (PFHxA and PFPeA) were not found in any participants. For people using private wells, PFOA and PFOS levels in drinking water were related to levels in blood.
