2、果表明,吸烟及吸二手烟对居民尿液中OH—PAHs的浓度水平和组成特征均有影响,对萘和芴的代谢产物影响最为显著.OH—PAl-Is的浓度水平按照吸烟组>吸二手烟组>不吸烟组的顺序递减.吸烟组和吸二手烟组人群尿液中萘的代谢产物2一羟基萘和卜羟基萘所占的比例分别是不吸烟组人群的1.5、1.2倍和1.7、1.9倍;吸烟、吸二手烟和不吸烟人群体内各OH—PAHs之间的相关性分析表明,吸二手烟人群体内OHPAHs来源最为复杂,受环境空气和香烟烟雾的双重影响.与同类研究结果相比,本研究吸二手烟人群体内OH-PAH
3、s明显偏低,这可能与吸二手烟人群受到烟气的暴露时间和暴露量有关.关键词:吸烟;二手烟;多环芳烃羟基代谢物(OH—PAl-ls):内暴露中图分类号:X503.1文献标识码:A文章编号:1000—6923(2014)06—1586—06ImpactofsmokingandpassivesmokingOHpolycyclicaromatichydrocarbonsinternalexposurelevels.XIALing,ZHAOBo,WANGBo.guang,ZHANGSu.kun2,RENMing.
