摘要：

A gas chromatograph/electron capture detector-ion trap mass spectrometer (GC/ECD-ITMS) was used for the determination of polybrominated diphenyl ethers (PBDEs) in euryhaline fish and crabs. GC/ECD-ITMS results showed that average recoveries from the spiked fish samples are in a range of 58-123% with relative standard deviations (RSDs) of 5-19%. PBDE concentrations obtained from GC/ECD-ITMS ranged from 28 ng/g to 1845 ng/g lipid weight (1w) in all aquatic species collected from Hawaiian brackish waters. The general BIDE congener concentration profile observed in this study is BDE-47 > BDE-100>BDE-154>BDE-99>BDE-153>BDE-28>BDE-183. The ELISA results expressed 2 as BDE-47 equivalents correlated well with those of GC/ECD-ITMS, with a correlation coefficient (R-2=0.68) and regression coefficient (slope=0.82). Comparison of ELISA with GC/ECD-ITMS results demonstrated that ELISA provides a timely and cost-effective method to screen PBDEs in fish and crab samples. (C) 2008 Elsevier Ltd. All rights reserved.
