| Abstract: | This study,with an emphasis on strict QA/QC performances,developed a method for polybrominated diphenyl ether(PBDEs) detection in fish tissue.It employed Soxhlet extraction,gel permeation chromatography column,multilayer silica and alumina column for clean-up/fractionation to process fish tissue samples.The final extracts were analyzed for 11 PBDE congeners with GC-NCI MS in the selective ion monitoring mode.The recoveries of surrogate standards(~(13)C-PCB-141 and PCB 209) ranged from 79% to 105% and from 76% to 108%,respectively,for a total of 29 samples.In 18 spiked samples(six blank spikes and six matrix spikes for fresh-water fish,and six for marine fish),the recoveries of the ten target analytes were between 94% and 120%,except that the recoveries of BDE209 were larger than 120% in a few samples.The instrumental detection limit for PBDEs from tri-to hepta-BDEs(i.e.,BDE-28,47,66,100,99,85,154,153,138,and 183) were in the range of 0.19 pg to 1.00 pg,and was 16.4 pg for deca-BDE(209).Low method detection limits for the target analytes except for BDE209,satisfactory recoveries,and good reproducibility were obtained,indicating that this method was suitable for determination of PBDEs in biota samples. |
