摘要
随着汽车的普及,由内饰件引起的车内污染问题也日益引起人们的关注.利用环境舱法探究了方向盘套、座垫、脚垫、座椅头枕等12 款产品在夏季高温条件下的挥发性有机物(volatile organic compounds,VOC)释放量,并建立了相应的车内"五苯三醛"吸入风险评估模型.结果表明:这些内饰件中释放的重点VOC以烷烯烃、苯系物、醛酮和醇醚类物质为主,且座垫和脚垫释放的丙烯醛对司乘人员有较大的非致癌风险.该研究为内饰件中VOC释放到车内的暴露风险评估提供新思路.
Abstract
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.
