Abstract

An analysis method based on matrix solidphase dispersion MSPD and gas chromatography tandem mass spectrometry was developed and applied for the analysis for organochlorine pesticides OCPs and polychlorinated biphenyls PCBs in the marketed seafood such as fish shrimp and shellfish The parameters of the method including the type and amount of the absorbent as well as the type and volume of the elution solution were optimized The recoveries were between 70 and 120 with RSDs less than 20 and the LODs and LOQs were 0011–0046 and 0037–0153 ng g−1 under optimized conditions The results showed that most of the OCPs and PCBs were detectable in the marketed samples with the average concentration range of 0722–14206 and 0034–1184 ng g−1 respectively Among the 21 OCPs detected DDTs had a relatively higher concentration level And in the PCBs the concentration of PCB28 was over 45 of the total PCBs determined in all the samples The developed method was simple fast and effective and could successfully be applied for trace amount of OCPs and PCBs determination in seafood matrixesWeijia Li declares that she has no conflict of interest Donghui Liu declares that she has no conflict of interest Jindong Li declares that he has no conflict of interest Jing Gao declares that she has no conflict of interest Chuntao Zhang declares that she has no conflict of interest Peng Wang declares that he has no conflict of interest Zhiqiang Zhou declares that he has no conflict of interestThis article does not contain any studies with human participants performed by any of the authors All animal experiments in the present study were carried out in accordance with institutional and national guidelines for the care and use of laboratory animals
