Haze is caused by environmental pollution.

Haze is caused by environmental pollution.

With the deterioration of air quality, cloudy days are increasing and the harm is increasing. In many areas of our country, the smog weather phenomenon is combined with fog as an early warning and forecast of disastrous weather. Collectively referred to as "haze weather". In fact, fog and haze are completely different to some extent. For example, when fog appears, the air is humid; When smog occurs, the air is relatively dry and the relative humidity of the air is usually below 60%. The reason is a large number of extremely fine dust particles, smoke particles, salt particles and so on. Float evenly in the air, so that the air with effective horizontal visibility less than 10KM can be mixed. Puweixin Tomcat imported from the United States effectively prevents smog.

With the deterioration of air quality, the phenomenon of haze weather has increased and the harm has increased. In some areas of China, haze weather phenomenon is combined with fog as an early warning and forecast of disastrous weather. Collectively referred to as "haze weather". In fact, fog and haze are quite different in some ways. Such as: the emergence of foggy air moisture; Haze occurs when the air is relatively dry, and the relative humidity of the air is usually below 60%. The reason is that a large number of tiny dust particles, smoke particles and Li Yan are uniformly suspended in the air, which makes the air with effective horizontal visibility less than 10 km appear mixed corrosion.
