对北京地区母乳中多溴联苯醚(PBDEs)的含量进行了研究，结果表明，母乳中多溴联苯醚(PBDEs)含量较高。对北京地区205名母亲的23份混合母乳样品中的6种主要多溴联苯醚(BDE47、BDE99、BDE100、BDE153、BDE154和BDE183)进行了测定。邮件样品中Sigma PBDEs浓度的平均值和中位数分别为1.12 ng g(-1)脂和1.07 ng g(-1)脂。城市(1.22 ng g(-1)脂肪，n=14)和农村(0.97 ng g(-1)脂肪，n=9)的Sigma PBDEs浓度存在统计学差异，BDE47和BDE153之和占大多数样品中Sigma PBDEs的70%以上，且混合样品中的Sigma PBDEs与城市水塘动物性食物的平均消费量显著相关。然而，北京农村水池样品中的西格玛多溴二苯醚与动物源性食物的平均消费量之间并未发现相关关系。目前的研究表明，北京地区母乳中多溴二苯醚的含量低于中国南部地区和美国、瑞典等发达国家。(C)2008爱思唯尔有限公司。保留所有权利。
The levels of polybrominated diphenyl ethers (PBDEs) in breast milk from Beijing, China, were Studied. The 6 predominant PBDEs congeners (BDE47, BDE99, BDE100, BDE153, BDE154 and BDE183) in 23 pooled breast milk samples from 205 mothers living in Beijing were measured. Mean and median of Sigma PBDEs concentrations mail samples were 1.12 ng g(-1) lipidand 1.07 ng g(-1) lipid, respectively. The Statistical difference in Sigma PBDEs concentrations was found between urban areas (1.22 ng g(-1) lipid, n = 14) and rural areas (0.97 ng g(-1) lipid n=9),The sum of BDE47 and BDE153 accounted for more than 70% of Sigma PBDEs in most samples.The significant correlation was found between the Sigma PBDEs in pooled samples and average of consumption of food of animal origin in the pools in urban area. However, there was no correlation Was found between the Sigma PBDEs in pooled samples and average of consumption of food of animal origin in the pools in rural area of Beijing. The Current study showed that the level of PBDEs in breast milk from Beijing was lower than that from South China and some developed countries such as USA and Sweden. (c) 2008 Elsevier Ltd.
