The Determination of PCBs in Meat and Sea Food by GC-QqQ-MS/MS

A new method was developed for the determination of 12 polychlorinated biphenyls (PCBs) in meat and sea food by gas chromatography coupled to triple quadrupole mass spectrometry using selected reaction monitoring technique. The method was based on ultrasonic extraction and florisil column cleaning up. Recoveries of the 12 PCBs ranged from 70.4 % to 100.6 % and the relative standard deviations were from 0.5 % to 12.6 %. The limits of detection ranged from 0.006 to 0.009 μg/kg and the limits of quantitation ranged from 0.02 to 0.03 μg/kg. Eight meat and sea food samples were analyzed for the analysis of the polychlorinated biphenyls using the proposed method.
