With the popularization of automobiles,the problem of interior pollution caused by interior parts has increasingly at-tracted people's attention.This article uses the environmental chamber method to explore the volatile organic compound(VOC)emissions of 12 products,including steering wheel covers,seat cushions,floor mats and seat headrests,under high-temperature conditions in summer,and establishes a corresponding risk assessment model for inhalation of air pollution in car.The results in-dicate that the key VOCs released from these interior parts are mainly alkylenes,benzenes,aldehydes,ketones,alcohols and es-ters,and the acrolein released from seat cushions and floor mats poses a significant non-carcinogenic risk to drivers and passen-gers.This study provides a new approach for assessing the exposure risk of VOC emissions from interior parts.
