New Vehicles Cabin Indoor Air Quality

New motor vehicles cabins may be critical when considering the indoor air quality, because concentrations of volatile organic compounds are at levels higher than the outdoors. Certain substances present in the cabin air can be harmful to humans according to their toxicity. Assessment of the cabin air becomes necessary. In this study, cabin air quality was assessed and 7 standard popular new vehicles containing same interior trim materials were evaluated. A total of 46 volatile organic compounds were identified, with 14 carbonylic compounds and 32 with aliphatic and aromatic hydrocarbons, halogenated compounds and a nitrogenated compound. The carbonylic compounds were identified and quantified by the liquid chromatography and other VOCs only identified by gas chromatography coupled with mass spectrometry.
