Experimental Investigation on the Reaction Characteristics between Ozone and Vehicle Cabin/Furniture Materials

Volatile organic compounds (VOCs) emitted from building and vehicle cabin materials seriously affect indoor in-cabin air quality, as well human health. Previous studies revealed that some VOCs could react with ozone to the concentration levels of environment, but seldom refers materials. In this study, we performed experimental investigation for two kinds (car carpet, sealing strip) one furniture material (medium-density fiberboard) by conducting small-scale chamber tests under different conditions, (about 110 μg/m3) without 10 μg/m3), explore effect chemistry on VOC emissions. We observed changes in scenarios found had a significant impact concentrations aldehydes ketones while having little benzene series. introduced gain ratio quantitatively reflect presence ozone. The is greater than one, series basically around small fluctuation range. This study demonstrates can containing unsaturated carbon–carbon bonds or carbon–oxygen varied produce ketones, which will further reduce quality.
