Community exposure to perfluorooctanoate: relationships between serum levels and certain health parameters

J Occup Environ Med. 2006 Aug;48(8):771-9. doi: 10.1097/01.jom.0000233380.13087.37.

Abstract

Objective: The objective of this study was to determine whether certain biomarkers of toxicity and/or a past diagnosis of liver or thyroid disease were associated with serum perfluorooctanoate concentrations (PFOA) in a community with longstanding environmental exposure to PFOA.

Methods: Serum (PFOA), hematologic and biochemical biomarkers, and a questionnaire were administered to 371 residents selected by stratified random sampling and a lottery among volunteers. Median PFOA was 354 ng/mL (interquartile range, 181-571 ng/mL).

Results: No significant positive relationships between serum (PFOA) and liver or renal function tests, cholesterol, thyroid-stimulating hormone, or with red cell indices, white cell, or platelet counts. Mean serum (PFOA) was not increased in those with a history of liver or thyroid disease.

Conclusions: No toxicity from PFOA was demonstrated using the measured end points; other end points need to be addressed.
