摘要：Polybrominated diphenyl ethers (PBDEs) are potential persistent organic pollutants which have raised many concerns in recent years. Research focusing on children exposure to PBDEs is important but insufficient. The levels and patterns of PBDEs in children's plasma from Dalian, China were studied for the first time. Seventeen PBDE congeners (BDE-30, 28, 35, 37, 75, 47, 66,100, 99,116, 155,154,153, 183, 181, 190 and 209) in 29 plasma samples were measured. Median PBDE concentration was 31.61 ng g(-1) lipid. BDE-153 was the dominant congener, followed by BDE-99, 47, and 183. High abundance of BDE-183 suggested a higher Octa-BDE use in China. No significant differences were observed between males and females or among different age groups. The levels of PBDEs in children's plasma in the present study were 9-30 times higher than those in non-occupational exposure people from Guangzhou, South China and those in human milk of general adults from other cities of China, but were at the moderate levels of those in children around the world. These results indicate that children in Dalian are at a high risk of exposure to PBDEs. (c) 2009 Elsevier Ltd. All rights reserved.
