目前空气污染已给全世界人群的健康带来极大威胁,常见的空气污染物包括颗粒物,臭氧,二氧化氮,二氧化硫等,其中化学组成最复杂、危害最严重的是细颗粒物PM2.5,指空气动力学直径小于或等于2.5微米的颗粒物。随着人们对PM2.5的关注逐渐增加,以及流行病学、毒理学方面资料的不断补充,PM2.5进入人体后引起的健康危害效应也逐渐明确。PM2.5随着呼吸进入体内后对人体健康的影响主要分为短期和
At present, air pollution has posed a great threat to the health of people all over the world. Common air pollutants include particulate matter, ozone, nitrogen dioxide, sulfur dioxide and so on. Among them, the chemical composition is the most complicated and the most serious is the PM2.5, Means aerodynamic diameter of less than or equal to 2.5 microns of particulate matter. As people pay more attention to PM2.5, as well as epidemiology and toxicology, PM2.5 gradually evolves its health hazard effect into the human body. PM2.5 With the breath into the body after the impact on human health can be divided into short-term and
