摘要

The present study determined fourteen PBDE congeners in human breast milk collected during 2004 from primiparous mothers living at two locations in China including an urban city(Nanjing)and a coastal area(Zhoushan).PBDEs were detected in all human milk samples of the present study,indicating general population in these two locations were widely exposed to these pollutants.Spatial distribution showed that concentrations of PBDEs are relatively higher in Nanjing than Zhoushan,indicating significant sources in urbanized area.Levels of PBDEs in the present study was quite similar with those in European countries,but still one or two orders of magnitude lower than North America,the region which consume the largest quantities of penta commercial mixtures of PBDE.Except BDE-3,all congeners from di-to deca-BDE were detected in human milk samples of the present study.BDE-209,a congener which is considered as having less bioavailability,was also detected in around 50% of the samples with concentrations higher than other congeners.Interestingly,higher brominated congeners,such as BDE-153,BDE-197 and BDE-207 were the predominant congeners,which was not the pattern generally found in various studies on human milk as well as other biota samples.This result may indicate specific sources of BFRs and exposure of the people in Nanjing and Zhoushan of the present study.
