对人类血液和母乳的横断面调查显示,多溴二苯醚的浓度在不断增加,这与消费品中多溴二苯醚的使用范围扩大相平行,但缺乏纵向研究。我们比较了1994-1995年从一组经常和不经常食用五大湖鱼类的人群中采集的存档血液样本中主要溴化二苯醚同系物的水平,以及2001-2003年和2004-2005年从同一个体中采集的血液中的水平。在控制每个个体和协变量的多重测量值的混合线性回归模型中,从1994-1995年到2001-2003年,溴化多溴二苯醚和BDE-47、99和153的含量出现了统计学上的显著增加,从1994-1995年到2004-2005年,溴化多溴二苯醚和BDE-99、100和153的含量也出现了统计学上的显著增加。但2001-2003年和2004-2005年期间,多溴二苯醚和溴二苯醚同系物没有发生重大变化。男性体内多溴二苯醚和BDE-47、BDE-100和BDE-153的含量变化受体重指数的影响,体重指数越高的男性增加越多。女性中BDE-153的增加幅度大于男性,老年参与者中BDE-100的增加幅度更大。同源物的分布发生了变化,从2001-2003年到2004-2005年,BDE-153相对于BDE-47的比例显著增加。
Cross-sectional surveys of human blood and breast milk show increasing concentrations of polybrominated diphenyl ethers (PBDEs) that parallel the expanded use in consumer products, but longitudinal studies are lacking. We compared levels of major BDE congeners in archived 1994–1995 blood samples collected from a cohort of frequent and infrequent Great Lakes fish consumers with levels in the blood collected from the same individuals in 2001–2003 and 2004–2005. In mixed linear regression models controlling for multiple measurements per individual and covariates, statistically significant increases were seen from 1994–1995 to 2001–2003 for ΣPBDEs and BDE-47, 99, and 153 and from 1994–1995 to 2004–2005 for ΣPBDEs and BDE-99, 100, and 153, but ΣPBDEs and BDE congeners did not change significantly between 2001–2003 and 2004–2005. Changes in body burdens of ΣPBDEs and BDE-47, 100, and 153 in men were modified by BMI, with greater increases in men with higher BMI. Increases in BDE-153 were greater for women than men, and a greater increase in BDE-100 was found in older participants. There was a shift in the congener distribution with a significant increase in the proportion of BDE-153 relative to BDE-47 from 2001–2003 to 2004–2005.
