认识雾霾雾霾,是雾和霾的统称。雾和霾的区别十分大。空气中的灰尘、硫酸、硝酸等颗粒物组成的气溶胶系统造成视觉障碍的叫霾。当水汽凝结加剧、空气湿度增大时,霾就会转化为雾。雾霾是对大气中各种悬浮颗粒物含量超标的笼统表述。空气颗粒物对人体健康具有明确意义上的相关性,颗粒物的粒径决定其最终进入呼吸道的部位及沉积量。
Understanding smog Haze is a general term for fog and haze. The difference between fog and haze is very large. Airborne dust, sulfuric acid, nitric acid and other particulate matter composed of aerosol system caused by visual disturbance haze. When the water vapor condensation intensified, the air humidity increases, the haze will be converted to fog. Smog is a general expression of the excess of various suspended particulate matter in the atmosphere. Airborne particulate matter has a clear, meaningful correlation with human health, and the particle size of the particulate matter determines where it eventually enters the respiratory tract and the amount deposited.
