Abstract：A listof31 VOCs with risk limits for human health isobtained bysorting out thecompounds in the in vehicle/indoorairqualityguidelinesof11countries.M1typenewvehiclesarechosenasobjects，aquantitativeanalysis of104volatile organic compounds in cabin of vehicle isconductedbased onthesumma canistergas chromatography-mass spectrometry method.The testresultsare compared with the listguidelines to screen forrisk volatileorganiccompoundsincabinofvehicle.Exceptforthe8itemsintheinternational standard，thescrening result showsrisk volatile organic compounds in the cabin ofvehicle include dichloromethane （2.45～706μg/m3. L vinyl acetate （0.91～440μg/m3） ，4-methyl-2-pentanone ，naphthalene ），butadiene ，carbontetrachloride （0～7.15μg/m3， ），trichloroethylene （O ），1，2-dibromoethane ） Suggestionsforthesubsequentrevisionof thenational standardforvehicleairqualityinclude expanding the management listofVOCsintheindoorair，reevaluating thelimitvaluesof8substancesinthecurrentnational standard，and setting2 limit values forpreventiveand hazardous concentrations.
