Polybrominated Diphenyl Ethers and Other Persistent Organic Pollutants in Serum Pools from the National Health and Nutrition Examination Survey: 2001-2002.

ABSTRACT: Polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyls (PCBs), and persistent pesticides have been measured in serum pools from participants 3-5, 6-11, 12-19, 20-39, 40-59, and ?60 years of age from the 2001-2002 National Health and Nutrition Examination Survey. For 2,2',4,4'-tetrabromodiphenyl ether (PBDE-47), the unweighted (not adjusted for sampling weights) arithmetic mean concentration (±95% confidence interval) was 3.4 times higher in 3-5-year-olds (216 ± 30 ng/g of lipid) than in 12-19-year-olds (64 ± 11 ng/g of lipid), with no apparent change with increasing age for adults ?20 years of age. By contrast, unweighted arithmetic mean concentrations of traditional persistent organic pollutants (POPs) such as hexachlorobenzene (HCB) and 2,2',3,3',4,4',5,5'-octachlorobiphenyl (PCB194) were 2- and 20-fold higher, respectively, in persons ?60 years than in 12-19-year-old adolescents. Findings suggest higher exposures to PBDEs but lower exposures to traditional POPs in 3-5-year-old children than in adults.

Project description:Eleven polybrominated diphenyl ether (tri- to deca-BDE) congeners and 2,2',4,4',5,5'-hexabromobiphenyl (BB153) have been measured in pooled serum samples from the National Health and Nutrition Examination Survey (NHANES) for one decade (from survey years 2005/06 through 2013/14). The pools, which are representative of the general noninstitutionalized population of the United States, encompassed thirty-two demographic groups defined by sex, race/ethnicity (Mexican American, non-Hispanic black, non-Hispanic white, and all other race/ethnicities), and age (12-19, >20-39, >40-59, and ?60 years). The adjusted geometric means were determined in a multiple linear regression model for the six congeners (BDE28, BDE47, BDE99, BDE100, BDE153, and BB153) with detectable concentrations in at least 60% of pools in each of the thirty-two demographic groups; the level of significance for all statistical comparisons thereof were determined. BDE154 and BDE209 were detected in 60% of the NHANES 2011/12 and 2013/14 pools; only these two survey periods were evaluated for these congeners. The percent change in concentration by a 2-year survey period was calculated. All examined PBDEs reported in five survey periods decreased in concentration, except BDE153, for which concentrations increased by 12.0% (95% CI 7.1-16.4) and 8.4% (95% CI 2.9-14.1) for the age groups 40-59 and ?60 years, respectively; no significant change was observed in younger age groups. Excluding BDE153, we observed larger percentage decreases by a 2-year survey period for the age groups 12-19, 20-39, and ?60 years compared with the age group 40-59 years. The percentage decrease by a two-year survey period ranged between -19.6% (BDE99, 20-39 years old) and -4.5% (BDE100, 40-59 years old). Although five polybrominated diphenyl ether (PDBE) congeners and BB153 are still frequently detected in the U.S. general population, PBDE concentrations have decreased since 2005-2006, likely, because of changes in manufacturing practices that started in the mid-2000s.
