PM2.5 的暴露评估是开展大气污染健康影响研究的必需环节.目前,中国人群 PM2.5污染暴露评估数据主要依靠固定站点获得,但由于环境监测站点的浓度水平和实际个体暴露水平存在差异,直接利用站点污染值进行个体暴露评估将不够准确.本研究采用模型技术,在 PM2.5 个体暴露估算模型的基础上构建一套 PM2.5 暴露实时采集技术,通过使用个体暴露行为模式定位数据对室外固定站点与室内在线监测数据进行匹配与加权,来模拟 PM2.5 个体暴露水平,搭建PM2.5 个体暴露科研集成平台.

目前我国主要的空气污染物是细颗粒物(PM2.5)、臭氧和可吸入颗粒物(PM10),以它们为首要污染物而导致空气质量超标的天数分别占 66.8％、16.9％和 15.0％[1].其中,PM2.5 被吸入后,可到达肺泡,即到达呼吸系统的终端,并能被吸收入血.所以,研究者们格外重视对 PM2.5 的研究.
纳米颗粒进入生物环境时,因其较高的表面自由能,会迅速吸咐周围的生物分子,形成生物分子冕,其核心层吸附紧密难以脱落,被认为是纳米颗粒物在人体内新的身份标识[1].迄今为止,有关生物分子冕的研究集中在颗粒与血浆的交互作用上,而作为颗粒物进入人体的最主要途径,肺部环境中纳米颗粒与肺表面活性剂交互作用形成分子冕的研究极为缺乏.
