Research of Polychlorinated Biphenyls (PCBs) in Vegetables by GC-MS/MS
Polychlorinated biphenyls (PCBs), one of the most famous "dirtydozen" persistent organic pollutants (POPs) with carcinogenicity, teratogenicity and mutagenicity, are used to be produced and commercially used as mixtures. Even PCBs were banned by most countries as early as 1970s, they can still be detected in air, soil, water, sediment and biota at a global scale, even in remote areas such as the polar regions, deep seas and high mountains. In this study, we established a rapid detection method of 7 kinds of Polychlorinated biphenyls (PCBs) in vegetables, the analysis method of using QuEChERS pretreatment method, combining with MRM mode of gas chromatography triple quadrupole tandem mass spectrometry which has characteristics of strong anti-interference ability, high sensitivity and high throughput of ion transport efficiency, so that it can complete the accurate identification of target compounds under complex matrix. According to the results, the proposed method is ideally suited for the routine monitoring and rapid screening of the 7 kinds of Polychlorinated biphenyls (PCBs) in vegetables.
