Abstract:
A rapid analytical method has been developed for the determination of polybrominated diphenyl ethers (PBDEs) in vegetables. PBDEs were determined by gas chromatography with negative chemical ionization mass spectrometric detection in the selected ion monitoring mode (GC-NCI-MS-SIM). The method detection limits (MDLs) were evaluated as 5 times the signal/noise (S/N) ratio in the GC/MS peaks by analyzing spiked vegetable samples at 2 - 50 ng/g. The minimum limits of instrument detection for this method were 0.28 - 0.78 pg for tri- to hepta-BDEs and 3.60 pg for deca-BDEs respectively. The minimum limit of method detection for tri to hepta-BDEs was 28 pg/g dry weight and 360 pg/g dry weight for deca-BDEs. In the examined vegetable samples, BDE-209 was the prominent congener detected in most cases, followed by BDE-47, BDE-71. The total concentration of PBDEs was in the range of 53.38 - 2884.02ng/g dry weight.
