雾霾会给人带来哪些伤害?如何做好自我防护?雾霾天呼吸系统最受伤雾霾天空气中的主要污染物为可吸入颗粒物和气态污染物,包括二氧化硫、二氧化氮、臭氧、一氧化碳等。可吸入颗粒物的主要组分为硫酸盐、硝酸盐、黑炭、有机碳和金属粒子(如镍、镉、铅)等。可吸入颗粒物的粒径在10μm及以下,直径越小进入呼吸系统位置越深。而2.5μm及以下的细颗粒物可深达肺泡,并沉积
Haze days What is the most harmful haze days? The main pollutants in the air are respirable particulate matter and gaseous pollutants, including sulfur dioxide, nitrogen dioxide, ozone, Carbon monoxide and so on. Respirable particulate matter is mainly composed of sulfate, nitrate, black carbon, organic carbon and metal particles (such as nickel, cadmium, lead) and so on. Respirable particulate matter particle size of 10μm and below, the smaller the diameter of the deeper into the respiratory system position. The 2.5μm and below the fine particles can reach the alveoli, and deposition
