Fish Consumption and Concentrations of Polybrominated Diphenyl Ethers (PBDEs) in the Serum of Older Residents of Upper Hudson River Communities

ABSTRACT

A study was conducted to evaluate exposure to polybrominated diphenyl ethers (PBDEs) among 144 men and women 55 to 74 years residing along the Hudson River. The results indicated a median serum PBDE concentration of 23.9 ng/g lipid wt. This value is similar to those of other New York State studies of populations that are younger and proportionately more likely to be male, suggesting that pathways do not differ by age or sex. Individual congeners were highly correlated, but they were not associated with concentrations of polychlorinated biphenyls (PCBs). Persons with a body mass index (BMI) > 30 had a geometric mean ΣPBDE concentration of 46.7 versus 25.2 ng/g lipid wt for persons with a BMI ≤ 30 (p = .006). Fresh water fish consumption was not associated with serum PBDE concentrations in this population.
