Abstract
A gas chromatography-mass spectrometry (GC-MS) was use. d for the determination of 18 kinds of polybrominated diphenyl ethers (PBDEs) and polybromominated biphenyls (PBBs) in soils.The sample was extracted by accelerated solvent extraction (ASE) and cleaned up by gel permeation chromatographic technique (GPC). 13C-labeled PCB and PBDE were added as internal standard and surrogate compound for quantitative determination. GC-EI/MS was used to analyze low-brominated PBDEs and PBBs, while GC-NCI/MS was applied for high-brominated PBDEs and PBBs, including BB-209, BB-206, BB-194 and BDE-209. Isotope dilution method was used for the analysis of BDE-209 to obtain accurate data. The average recoveries were 43.8％- 97.2％ (n= 22) and relative standard deviations were 18％-31％. The limit of detection (LOD) of all the compounds were 0. 15-0.43 ng/g, and LOD of BDE-209 was 4.0 ng/g. The method is highly sensitive, accurate, and specific for the quantitative determination for PBBs and PBDEs in soil. Furthermore it is practically satisfied for a general survey employing the analytical method.关键词
