What's the weather like smog?

Haze is the weather with high humidity and low visibility.

Haze, also known as haze, refers to the turbidity caused by the suspension of a large number of particles such as smoke and dust. The core substance of smog is dust particles suspended in the air, which are called aerosol particles in meteorology. In recent years, the occurrence frequency of "smog" weather phenomenon is getting higher and higher, which leads to the gradual deterioration of air quality. Haze contains hundreds of atmospheric chemical particles, which intrude into human respiratory tract and lung lobes unsuspecting, thus causing respiratory diseases, cardiovascular diseases, blood system, reproductive system and other diseases, such as pharyngitis, emphysema, asthma, rhinitis, bronchitis and other inflammation. Long-term exposure to this environment will also induce lung cancer, myocardial ischemia and injury. Smog also often causes traffic accidents.
