摘要
甲氧基多溴联苯醚(methoxypolybrominated diphenyl ethers,MeO-PBDEs)广泛存在于生物体和海洋环境。以象山海域的生物体和沉积物为样本,采用固相萃取净化-气相色谱-负化学源质谱法,检测了6种MeO-PBDEs,结果显示,当目标分析物浓度为0.1~20.0μg·L^(−1)时,线性关系良好(R^(2)>0.999),检出限为0.13~0.22μg·kg^(−1),定量限为0.42~0.72μg·kg^(−1),实际样品的平均回收率为71.2%~116.2%。MeO-PBDEs的分布状况调查结果显示,藻类样品中仅检出6-MeO-BDE-47,且浓度较低,其他生物体中检出3种MeO-PBDEs,检出率为31.3%,浓度为0.21~2.72μg·kg^(−1)。沉积物中无MeO-PBDEs被检出。
Methoxypolybrominated diphenyl ethers(MeO-PBDEs)were widely present in marine organisms and the marine environment.An analytical method of six methoxypolybrominated diphenyl ethers for biological samples and sediment samples from Xiangshan Sea area using solid-phase extraction and gas chromatography coupled with negative chemical ionization mass spectrometry was developed and optimized.The developed method exhibited satisfying linearity in the range of 0.1-20.0μg·L^(−1)(R^(2)>0.999).The detection limit(LOD)and limit of quantitation(LOQ)for MeO-PBDEs were 0.13-0.22μg·kg^(−1) and 0.42-0.72μg·kg^(−1) respectively.The spiked recovery was 71.2%-116.2%.The method was applied to the analysis of marine organisms and sediments collected from Xiangshan sea area.All kinds of MeO-PBDEs were not detected in sediment samples.Only 6-MeO-BDE-47 was detected in algae samples with low concentration.Three MeO-PBDEs were detected in other biological samples,and the ratio of detection was 31.3%with a concentration range of 0.21-2.72μg·kg^(−1) MeO-PBDEs were not detected in sediment samples.
