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。总结了灰霾这一污染型天气的特征,介绍了灰霾的化学成分、污染机制等,并从影响机制和流行病学角度出发,对国内外灰霾对人体的健康效应研究成果进行了综合评述,提出目前急需解决的科学问题和今后的研究方向。
Haze or dust haze, mainly consisted of PM10 or PM2.5, can cause a decrease of visibility in the air and also exert adverse health to the human being. In this paper, the formation and behavior of haze were reviewed in terms of fundamental characteristics and definition, factors affecting the formation and properties, health effect on human being, chemical components, and epidemiology. It is found that the knowledge on haze is still quite limited and its effect on human health is not explored fully.
