How do we control smog?

1, the best way to control smog is to reduce the use of fuel vehicles. "Reducing pollution sources and air pollutants is the fundamental way to solve smog.

2. Try to reduce the contact frequency and area between car wheels and road dust in urban areas, make flower beds and shoulders lower than the roads where cars pass, and make rainwater, mud and polluted water flow from the middle of the roads to the soil under the flower beds.

3. Minimize the dust caused by vehicles and construction vehicles outside the city. When vehicles with dust outside the city enter the city, a link of washing tires and chassis with water spray can be set at the toll gate in the city, and a link of covering and washing tires and chassis can be set when construction vehicles enter the road in the city. However, many cities often only have the terminal penalty mechanism after entering the city, but there is no cleaning and prevention mechanism when entering the city.

Measures taken by countries to deal with smog:

The British reflected on the bitter fruit of air pollution, which gave birth to the promulgation of the first air pollution prevention and control bill, the Clean Air Act.

The European Union requires its member states that the number of days of air failure in 20 12 should not exceed 35 days, or they will face a huge fine of 450 million US dollars. In order to meet the standards, as early as 2003, the city government of London began to levy a "congestion charge" on private cars entering the city center.

In the 1980s, the government decided to try to use calcium-based adhesives in the streets to control air pollution. This adhesive is similar to glue and can absorb dust in the air. Street cleaners have used this new product in urban areas with noisy population and serious pollution. The monitoring results of 20 13 showed that the particulate matter in these areas decreased by 14%.
