First, the reasons for the formation of haze weather
1. Industrial emission: In the production process of heavy industries such as steel, chemical industry and electric power, a lot of waste gas and dust will be generated, which contains a lot of tiny particles.
2. Automobile exhaust: Automobile exhaust is one of the main sources of urban air pollution, especially the particulate matter emitted by diesel vehicle exhaust is more serious.
3. Agricultural activities: Agricultural activities such as straw burning will also produce a large number of tiny particles, which will affect air quality.
4. Natural factors: Climatic conditions such as humidity and wind direction will also affect the formation and spread of smog.
Second, the harm of smog weather
1. Impact on human health: tiny particles in smog can enter human lungs, causing irritation and damage to the respiratory system and increasing the risk of respiratory diseases.
2. Impact on the environment: Smog weather will reduce the air quality, affect the photosynthesis of plants and have a negative impact on the ecosystem.
3. Impact on traffic: The smog weather has low visibility, which easily leads to traffic accidents and brings inconvenience to traffic.
Three. Suggestions on haze weather
1. Strengthen the supervision of industrial emissions: The government should strengthen the supervision of industrial enterprises and reduce the emission of waste gas and dust.
2. Promote clean energy: encourage the use of clean energy, reduce fossil fuel consumption and reduce automobile exhaust emissions.
3. Advocate green travel: encourage the public to use public transport, ride or walk, reduce the use of private cars and reduce exhaust emissions.
4. Raise environmental awareness: strengthen environmental education, raise public awareness of environmental protection, and jointly protect our environment.
Types of smoke
1, slightly foggy
Mild smog refers to the low concentration of particulate matter and pollutants in the air, which has a certain impact on air quality and visibility, but has not yet reached a serious pollution level. This weather phenomenon usually occurs in densely populated areas such as cities and industrial areas, especially in winter and spring. Due to the influence of meteorological conditions and pollution sources, mild smog is prone to occur.
2. Mild haze
Mild smog is a relatively light air pollution phenomenon, which usually appears in densely populated areas such as cities or industrial areas. Due to the low concentration of particulate matter and pollutants in the air, mild smog has a certain impact on air quality and visibility, but it has not reached the level of serious pollution.
3. Moderate haze
Moderate smog is a moderately polluted weather phenomenon, which usually appears in densely populated areas such as cities or industrial areas. Due to the high concentration of particulate matter and pollutants in the air, moderate smog has a great impact on air quality and visibility, which may lead to cough, sore throat, chest tightness and other symptoms.
