What is "haze"?

Haze is weather with high humidity and low visibility.

Haze, also known as haze (smoke), refers to the turbidity caused by the suspension of large amounts of smoke, dust and other particles for unknown reasons. The core substance of haze is dust particles suspended in the air, which are called aerosol particles in meteorology. In recent years, "haze" weather phenomena have occurred more and more frequently, leading to a gradual deterioration of air quality. Haze contains hundreds of atmospheric chemical particulate matter, which invade the human respiratory tract and lung lobes when people are unprepared, causing diseases of the respiratory system, cardiovascular system, blood system, reproductive system, etc., such as pharyngitis, lung disease, etc. Inflammations such as emphysema, asthma, rhinitis, and bronchitis. Long-term exposure to this environment can also induce lung cancer, myocardial ischemia, and damage. The haze often causes traffic accidents.
