Fine Particulate Matter (PM(2.5)-particles with an aerodynamic diameter ≤2.5 μm) can penetrate deeply into the lung, deposit in the alveoli, and consequently impair lung function. Both short term and long term exposures to PM(2.5) are associated with the incidence of respiratory diseases (e.g. asthma, chronic obstructive pulmonary disease, lung cancer). This paper summarizes the effects of ambient air PM(2.5) exposure on human respiratory system revealed by epidemiological studies.
细颗粒物（PM2.5，空气动力学直径≤2.5μm的颗粒物）可深入肺部，沉积于肺泡，进而损害肺功能。短期和长期暴露于PM2.5均与呼吸系统疾病（如哮喘、慢性阻塞性肺疾病、肺癌）的发病率相关。本文总结了流行病学研究揭示的环境空气中PM2.5暴露对人体呼吸系统的影响。
