Assessment of lipid, hepatic, and thyroid parameters with serum perfluorooctanoate (PFOA) concentrations in fluorochemical production workers

A negative association with HDL was explained by demographic differences across the three locations. Several explanations are offered for the inconsistent triglyceride associations with PFOA including both methodological as well as biological possibilities.
