摘要
灰霾是颗粒物和气体污染物导致的可察觉到的能见度降低的污染天气现象。近年来,随着城市化进程的快速发展,城市大气污染加剧,灰霾天气也随之增多。介绍了灰霾天气的形成过程、化学成分及其危害,并从流行病学等角度出发,对灰霾天气对人体健康效应的研究成果进行了综述。
Haze or dust haze, mainly consisting of PM10 or PM2.5, can cause a decrease of visibility in the air. In recent years, with the rapid development of urbanization, the urban air pollution becomes more and more serious, and the number of days that dust haze occurs has increased. The formation of dust haze, the chemical component and the damage of dust haze weather are introduced. The study of the effects of dust haze weather on human body from the epidemiology is also reviewed.
