title: Exploratory assessment of sportfish consumption and polybrominated diphenyl ether exposure in New York State anglers.
abstract: A cross-sectional study was conducted to examine the influence of sportfish consumption on body burden of nine polybrominated diphenyl ether (PBDE) congeners in 36 New York State (NYS) anglers. Participating anglers who had previously reported consuming sportfish from Lake Ontario and its tributaries were found to have significantly higher blood plasma levels of BDE-28, BDE-47, BDE-99, BDE-100, and the sum of measured PBDE congeners (SigmaPBDE), than anglers who had previously reported no consumption of sportfish from these waters. Bivariate analysis was used to evaluate potential dietary predictors of PBDE plasma levels, including indicators of consumption of sportfish, as well as commercial fish, wild waterfowl, dairy products, and beef. The number of years of reported consumption of Lake Ontario sportfish between 1980 and 1990 was found to be correlated with plasma levels of BDE-47, BDE-85, BDE-99, BDE-100, BDE-153, BDE-154, and SigmaPBDE. The number of meals, eaten in the year prior to study participation, of Lake Ontario sportfish species known to have high levels of other persistent organic pollutants (POPs) was correlated with plasma levels of BDE-28, BDE-47, BDE-85, BDE-99, BDE-100, BDE-154, and SigmaPBDE. Multiple linear regression revealed that the number of years consuming Lake Ontario sportfish between 1980 and 1990, after adjusting for plasma lipids, was a weak, but statistically significant, predictor of SigmaPBDE plasma levels (beta=0.130, 95% CI: 0.007-0.254). These results suggest that sportfish consumption can contribute measurably to PBDE body burden in NYS anglers, although there are likely to be additional, more significant, sources of exposure.
