A Novel Method Verification of Determination of Polychlorinated Biphenyls in Ambient Air by Gas Chromatography-Mass Spectrometry
Polychlorinated biphenyls(PCBs)exist widely in the environment for a long time and caused great threat to human health,animals and plants.In order to meet the monitoring requirements of PCBs in ambient air,this manuscript provides a new method verification by gas-chromatoc-mass spectrometry for a broad spectrum PCBs measurements.According to the"Determination of PCBs in ambient air gas-chromatoc-mass spectrometry"(HJ 902-2017)standard,as a result,we obtained an excellent result.The experimental results showed that this new method verification have a good linear relationship for 27 PCBs and their derivatives in the concentration range of 25.0～500 μg/L,all correlation coefficients had exceed 0.997.Both of detection limit,precision and accuracy of the method verification are verified to conform to the HJ 902-2017 standard.The results show that this method verification can determine the ability of 27 kinds of PCBs and their derivatives in ambient air.
