Abstract： In order to solvethe residue detection problemof7kinds of new pesticides hazard factors （pentachloronitrobenene， oxychlorure，fenpyroximate，phthalthion，spiromesifen，pyrimethanilandisopropoxamyl）stipulatedinGB2763—201but lacking detectionmethods，this studydevelopsthecorrsponding pretreatment extractionpurifcationmethodsand instrument detectionmethods withSolanaceae （tomato）andaquatic （waterchestnut）asmatrices，and investigatestheresiduedegradation behaviorof 4 kindsof pesticide hazard factors during the process.LC-MS is used to optimize the chromatographic-mass spectrometryconditions and pretreatment parameters，andthe residuedetection methods of 7hazard factors are established， whichhavehighrecoveryrate tomeettherequirementsofthe method，highsensitivityandgoodaccuracy.Theestablished detection methods areapplied to theresidue of tomatoand water chestnuttreated diferent concentrations of pesticides under 4 C storage condition，andtheresidue degradation curve isdrawnandthe degradationrule isanalyzed.The research results provide technicalsupport for theaccurate detectionpesticides residues in tropical vegetables，andalso provideabasisforheir scientific use and storage safety in tropical vegetables.
