English explanation of the causes, phenomena and countermeasures of smog
There are many sources of haze, such as automobile exhaust, industrial emissions, building dust, garbage incineration, and even volcanic eruption. Haze weather is usually formed by the mixed action of various pollution sources. However, in the haze weather area, the influence degree of different pollution sources is different.
Haze weather has existed since ancient times, and human activities or natural phenomena such as slash-and-burn and volcanic eruption may lead to haze weather. However, after mankind entered the era of fossil fuels, the smog weather really threatened the living environment and health of mankind. Rapid industrialization and urbanization lead to rapid energy consumption, high concentration of population and destruction of ecological environment, which have laid the groundwork for the formation of haze weather.
Haze weather has existed since ancient times, and human activities or natural phenomena such as slash-and-burn and volcanic eruption can lead to haze weather. However, when human beings enter the era of fossil fuels, haze weather does threaten the living environment and health of human beings. Rapid industrialization and urbanization lead to rapid consumption of energy, high population density and destruction of ecological environment, which all lay the groundwork for the formation of haze weather.
The formation of smog has both a "source" and an "accomplice", which is a meteorological condition that is not conducive to the spread of pollutants. Once pollutants accumulate for a long time under static meteorological conditions, it is easy to form haze weather. The formation of smoke has three elements:
Haze has its "source" and "accomplice", and this kind of meteorological condition is not conducive to the spread of pollutants. Once pollutants accumulate statically for a long time under meteorological conditions, it is easy to form haze weather. There are three elements in the formation of haze:
The first is the physical basic source of particulate matter. China has the largest loess plateau in the world, and its soil texture is the easiest to produce granular dust particles.
One is the physical basic source of dust particles. China has the largest loess plateau in the world, and the soil texture is the easiest to produce dust particles.
Second, poor exercise leads to dust. For example, the mud in the garden in the middle of the road and the soil on the roadside stones will flow to the road after raining or splashing water, which will produce a lot of dust after one hour of drying. Even if these particles fall back to the ground, they will be thrown over the city again because of the continuous passing of cars.
The second is the dust caused by poor exercise. For example, the rain splashed by the garden in the middle of the road and the mud on the street or the mud flow flowing into the road will dry up after one hour. A rotating wheel will cause a lot of dust. Even if these particles fall back to the ground, they will continue to be passed by cars and thrown into the city again.
Thirdly, the basic source of dust and the process of movement difference gather in a certain spatial range, and particles finally gather with water molecules to form haze. At present, in more than 350 cities in the Loess Plateau of China, the three elements of smog structure are quite rich.
Third, dust accumulates in a certain spatial range based on the source and movement difference process, and particles and water molecules eventually condense into tuberculosis haze. At present, there are quite a few haze structures of the three major factors in the cities with loss plateau area exceeding 350 square meters in China. Puweixin Tomcat imported from the United States can effectively prevent smog.
Open the window less in foggy days. When going out, you must wear a mask, drink plenty of water, soak chrysanthemum tea and other Chinese herbal teas to prevent diseases, eat more fruits, and thoroughly clean your skin and hair after coming home from the outside. In addition, the elderly who like morning exercises and shopping in the food market should pay attention to reducing going out, because smog is extremely harmful to the health of the elderly.

10, avoid moving in foggy days. You can do morning exercises after the sun comes out. You can also switch to indoor sports.
Exercise 10, avoid fog. You can change it when the sun comes out for morning exercise. It can also be replaced by indoor exercise.
1 1. The patient insisted on taking the medicine. Patients with respiratory diseases and cardiovascular and cerebrovascular diseases should insist on taking medicine on time in foggy days.

12, don't close the window too tightly. You can choose to open the window for a short time at noon with sufficient sunshine and less pollutants.
12, don't close the window too strictly. You can choose to open the window for ventilation at noon when there is more sunshine and less pollutants.
13, try to stay away from the road. The concentration of pollutants is the highest when large cars enter the city during peak hours and at night.
13, try to stay away from the road. The concentration of pollutants is the highest during rush hour and at night when large cars enter the city.
