摘　　要：城市化进展促进了地铁系统的快速发展,地铁系统的细颗粒物(PM_(2.5))已经成为人们关注的焦点。测量了成都市典型地铁站及其对应隧道中的PM_(2.5)浓度,评估了不同人群暴露在地铁站中对PM_(2.5)的吸入剂量,给出了降低细颗粒物浓度和减少吸入量的建议。结果表明,地铁站台PM_(2.5)的平均浓度范围为22.23~31.22μg/m^(3)。在相同站台和相同性别的条件下,儿童PM_(2.5)的平均吸入剂量最低,其次是老年人。为地铁系统空气品质的提升提供了基础数据。The rapid development of the subway system has been promoted by the ongoing process of urbanization,and the fine particulate matter(PM_(2.5))in the subway system has become a primary focus of research.This study measured PM_(2.5) concentration in typical subway platforms and their corresponding tunnels in Chengdu,evaluated the inhalation dose of PM_(2.5) in different populations exposed to subway platforms,and provided suggestions to reduce the the inhalation dose of PM_(2.5).The results indicate that the mean concentration of PM_(2.5) in subway platforms ranged from 22.23 to 31.22μg/m^(3).Under the same station and same gender conditions,children exhibited the lowest mean inhaled dose of PM_(2.5),followed by the elderly.This study offers a foundational dataset for the enhancement of air quality within the subway system.
