利用半透膜被动采样装置，测定了荷兰海岸斯海尔德河口和沿着北海五个监测站中个别溴化二苯醚的水溶液浓度。观察到的值为0.1-5 pg l（-1）。最高浓度出现在斯海尔德河口。2月和10月之间，BDE-209的浓度差异为4-8倍，其他溴化二苯醚的浓度差异小于2倍。研究了本地贻贝和从未受污染地区移植到斯海尔德河口6周的贻贝的生物累积性。在本地贻贝中，溴化二苯醚和多氯联苯的浓度分别高出一倍和两倍。溴化二苯醚的实地生物累积系数比多氯联苯高10倍。净化实验表明，贻贝中的BDE-209含量大部分与摄入的颗粒有关，而其他BDE或多氯联苯则没有观察到这种影响。(C)2002爱思唯尔科技有限公司版权所有。
Aqueous concentrations of individual brominated diphenyl ethers (BDEs) were determined for five stations in the Scheldt estuary and the North Sea along the Dutch coast using passive sampling by semipermeable membrane devices (SPMDs). Values of 0.1-5 pg l(-1) were observed. The highest levels were found in the Scheldt estuary. Concentration differences between February and October were a factor of 4-8 for BDE209, and were smaller than a factor of 2 for the other BDEs. Bioaccumulation was studied for native mussels and for mussels that were transplanted from an uncontaminated area into the Scheldt estuary for 6 weeks. Concentrations in native mussels were higher by a factor of to and 2 for BDEs and PCBs, respectively. Field based bioaccumulation factors (BAFs) were higher for BDEs than for PCBs by a factor of 10. Depuration experiments showed that the larger part of the BDE209 content in mussels was associated with ingested particles, whereas no such effect was observed for the other BDEs or PCBs.
