| Abstract: | A method for the determination of trace polybrominated diphenyl ethers (PBDEs) in ambient air by high volume sampling followed with gas chromatography-negative chemical ionization mass spectrometry (GC-NCI-MS) was developed. The air samples were collected by PS-1 high volume air sampler and then were extracted, cleaned up and analyzed by GC-NCI-MS. The linear ranges of the method were from 5 to 10000 pg/m3 and detection limits were from 1 to 50 pg/m3. The method was applied to determining trace PBDEs in the... |
