中文摘要：
研究了包括京、津、冀、晋、甘全部，鲁、陕、青大部及内蒙小部在内的100万平方公里区域内多环芳烃的排放、污染、来源、分布格局、气地交换、扩散及人群暴露等区域环境过程。主要创新成果包括开发了用于区域分布和近地面空气多环芳烃垂直分布的被动采样装置；在定量表达影响能源消耗主要因素的基础上，建立了高空间分辨排放清单，确定了排放的季节变化规律；阐释了近地面多环芳烃的垂直分布特征，揭示了影响土壤多环芳烃空间分布格局的沉降和土壤有机质因素；测定了农村固体燃料燃烧的多环芳烃排放因子，建立了表征这些排放因子的主导影响因素的定量模型，弥补了生物质燃烧多环芳烃排放因子的数据短缺；建立了预测不同国家和年代机动车多环芳烃排放因子模型，及全球多年机动车多环芳烃排放数据库；阐明了中国东部大气中多环芳烃的空间分布特征以及中部和西部（青藏）地区土壤中多环芳烃的污染程度及分异规律；改进了测定多环芳烃在消化道中生物可利用性的体外暴露模型，发现了锁定多环芳烃的释放现象；定量表征了人群呼吸暴露导致的肺癌风险。这些成果对认识大尺度多环芳烃的产生、迁移和健康危害具有科学价值，也可为制定适合我国国情的多环芳烃控制策略提供科学依据。
