Background
Haze is an atmospheric pollution state, is a general expression for exceeding the content of various suspended particulate matters in the atmosphere, and particularly PM2.5 is considered as an 'allegory' causing haze weather. In recent years, with the deterioration of air quality, the occurrence frequency of the haze weather phenomenon is increasing, and the harm is increasing. In many areas, haze weather phenomena are combined into fog to be used as early warning and forecast of disastrous weather. Collectively referred to as "haze weather".
The haze contains various fine particles harmful to human bodies, and more than 20 toxic substances comprise acid, alkali, salt, amine, phenol and the like, as well as dust, pollen, mites, influenza viruses, tubercle bacillus, pneumococcus and the like. The sulfur dioxide, the nitrogen oxide and the inhalable particles are main components of haze, and the sulfur dioxide, the nitrogen oxide and the inhalable particles are combined with the fog to enable the sky to become grey and frosty instantly. The particles are not only pollutants, but also carriers of toxic substances such as heavy metals, polycyclic aromatic hydrocarbons and the like, and can bring great influence on human health.
The large outdoor billboard is mostly arranged on two sides of a road, and has a tall and big structure and is firm. As is known, dust flying and tail gas emission of automobiles on roads are one of the main reasons for causing haze, the dust flying on the roads is serious, particularly in the case of long-term dry and rainy weather, the wheels roll, dust flies, and the existing advertising board only has the function of showing local commodity information to passing drivers and passengers, and has a single function.
