摘要
BDE-209是溴代阻燃剂十溴联苯醚的主要成分,本研究应用GC-NCI-MS(气相色谱-负化学源-质谱)方法同位素稀释技术,测定了从沿海五省采集的48份贝类样品中BDE-209含量.所有样品中均检出BDE-209,含量范围为16.24—445.35 ng.g-1湿重,平均含量(61.29 ng.g-1湿重)显著高于国内外相关报道.其中,采自辽宁省的海蛎子样品BDE-209含量最高.结果提示,我国有关海域存在较为严重的BDE-209污染,应引起有关部门的关注.
The full-brominated congener BDE-209 is main ingredient of Deca-BDE formulation which are being produced and used greatly in China.In the present study,forty-eight shellfish samples were collected from five coastal provinces of China and were analyzed for the levels of BDE-209 using GC-NCI-MS（gas chromatography-negative chemical ionization-mass spectrum） with isotope dilution technique.BDE-209 was detected in all the samples with a range from 16.24—445.35ng·g^-1 wet weight.The highest value for BDE-209 was found in an oyster sample from Liaoning province.The levels in this study were higher than those from the previous studies in both China and abroad significantly,which indicated that extensively pollution of BDE-209 in Chinese coastal areas.
