Question 3: "The smog is too serious". The smog is very serious.

Haze is smoke.

1. What is smog?

Haze, as its name implies, is fog and haze. But there is a big difference between fog and haze. The aerosol system composed of dust, sulfuric acid, nitric acid and other particles in the air causes visual impairment, which is called smog. Haze is haze.

Fog is an aerosol system consisting of a large number of tiny water droplets or ice crystals suspended in the air near the ground. It mostly occurs in autumn and winter (which is also one of the reasons for the large-scale haze weather in China in June 20 13), and it is the product of water vapor condensation (or condensation) in the near-surface air. The existence of fog will reduce air transparency and worsen visibility. If the horizontal visibility of the target drops below 1000 meters, the weather phenomenon of water vapor condensation (or condensation) suspended in the air near the ground is called fog.

Haze (mái), also known as haze (smog), dust, sulfuric acid, nitric acid, organic hydrocarbons and other particles in the air can also make the atmosphere turbid. The phenomenon that the horizontal visibility of the target is 1000 ~ 10000 meters is called light fog or mist. When fog is formed, the atmospheric humidity should be saturated (if there are a large number of condensation nuclei, the relative humidity may not reach 100%, and saturation may occur). Because the light scattered by fog composed of liquid water or ice crystals has little to do with wavelength, the fog looks milky white or bluish white and gray.

Fine particles, also known as fine particles, fine particles and PM2.5 fine particles, refer to particles with aerodynamic equivalent diameter less than or equal to 2.5 microns in ambient air. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small part of the composition of the earth's atmosphere, it has an important impact on air quality and visibility. Compared with atmospheric coarse particles, PM2.5 has the advantages of small particle size, large area, strong activity and easy attachment of toxic and harmful substances (such as heavy metals and microorganisms). ), it stays in the atmosphere for a long time and has a long transportation distance, so it has a great impact on human health and atmospheric environmental quality.

Haze weather is a state of air pollution, and smog is a general term for all kinds of suspended particles in the atmosphere, especially PM2.5 (particles with aerodynamic equivalent diameter less than or equal to 2.5 microns) is considered as the "culprit" causing haze weather. 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".

Second, the air quality index.

Air quality index (AQI) is a dimensionless index that quantitatively describes air quality.

Air quality sub-indices are also specified for individual pollutants. The main pollutants involved in air quality assessment are fine particles, inhalable particles, sulfur dioxide, nitrogen dioxide, ozone and carbon monoxide.

The air quality is divided into six levels according to the size of the air quality index, which corresponds to the six categories of air quality. The greater the index and the higher the level, the more serious the pollution situation, and the greater the harm to human health, ranging from first-class excellent, second-class good, third-class light pollution, fourth-class moderate pollution, fifth-class heavy pollution to sixth-class serious pollution.

When the daily average concentration of PM2.5 reaches 150 μ g/m3, the AQI reaches 200; When the daily average concentration of PM2.5 reaches 250μ g/m3, the AQI reaches 300; When the daily average concentration of PM2.5 reaches 500 μ g/m3, the corresponding AQI index reaches 500.

According to the Technical Specification for Ambient Air Quality Index (HJ633-2012), the air pollution index is divided into 0-50, 5 1- 100,1-65438+.

The air pollution index is 0-50, the air quality level is Grade I, and the air quality status is excellent. At this time, the air quality is satisfactory, there is basically no air pollution, and all kinds of people can move normally.

The air pollution index is 5 1- 100, and the air quality grade is Grade II, so the air quality is in good condition. At this time, the air quality is acceptable, but some pollutants may have a weak impact on the health of a very small number of abnormally sensitive people. It is suggested that a very small number of extremely sensitive people reduce outdoor activities.

The air pollution index is 10 1- 150, and the air quality grade is ... >; & gt

Question 4: How to say ← _ ← smog (wù mái, expressed in English as *** og/haze) is a combination of fog and haze. Smog is very common in cities. In many areas of China, fog and haze are combined as disastrous weather phenomena for early warning and forecasting, which are collectively called "haze weather". In recent years, due to the deterioration of air quality, the smog phenomenon has increased and the harm has increased. When encountering foggy weather, try to take preventive measures, such as wearing a mask, and try to avoid outdoor activities.

Question 5: 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 extremely * * dust particles, ** oke, * * Li Yan and other particles are uniformly suspended in the air, resulting in mixed corrosion of air with effective horizontal visibility less than 10 km.

Question 6: How do you say "smog" under the dome in English? Haze is usually translated into haze, and it can also be translated into * * * OG (a combination * * * og(* * * * ooke and fog).

Question 7: Stay away from the smog and start with me. How to say stay away from the haze in English, starting with me?
