Henan launched early warning response to heavy pollution weather. Where does the main pollution come from?

Every early winter, we will encounter a very headache, that is, smog. Sometimes smog will seriously affect our daily life and bring inconvenience to our health. Henan has started the early warning of heavy pollution weather. The primary pollutant is PM2.5, which has small particle size, large area, strong activity, easy attachment of toxic and harmful substances (such as heavy metals and microorganisms), long residence time in the atmosphere and long transportation distance.

So what is the main source of such pollutants? The Henan Provincial Pollution Prevention Office issued an urgent notice saying that the air quality will be seriously polluted due to the high humidity, static stability and repeated transmission in the north and east.

This is also caused by the current climatic conditions. The high humidity and quietness in early winter are not conducive to the rapid dispersion of smog. Coupled with less rain and snow, smog hovers in the air for a long time, affecting people's travel and health.

At this time, a large number of leaves fell, and the crops harvested by farmers were already very dry and easy to ignite. Coupled with the solar terms of the Cold Clothes Festival, many people burn paper to worship and smoke in the kitchen, but because of the weather, it is not easy to spread, so this tiny particle will remain in the air in large quantities, which is easy to cause serious smog. Coupled with the humid weather, gouache in the air was atomized, and the weather was not very good, and there was no sunshine.

If farmers ignite vegetation in rural areas, it will cause smog and affect everyone's travel, and many factories also emit gas in the air, which has a great impact on people's health. In addition, people like driving now, so automobile exhaust emissions are also one of the important reasons for smog.

There are still some construction sites under construction. If you don't cooperate with the sprinkler operation, a lot of dust will be formed, which will also cause sound pollution and affect people's daily life.

Therefore, it is extremely important to reduce air emissions and smog in this season. In daily life, we should also pay attention to our health and take preventive measures to avoid respiratory diseases.

Try to minimize going out at ordinary times. When going out, people who like morning exercises should also pay attention to not exercising outdoors in the case of serious smog. Wearing a mask is a must for serious weather pollution, which can filter harmful pollutants to a certain extent.

Wash your hands and face, rinse your mouth, clean your nose, pay attention to hygiene, and try not to go to crowded places. Air pollution is serious, air mobility is poor, and cross infection is easy to form.

For heavy pollution, smog may be more serious in rural areas, and it is mostly moisture. When the sun came out, the smog dispersed. However, in cities, the dust is flying, cars are constantly emitting exhaust gas, and some factories are emitting some gases in the air. These gaseous substances have an impact on people's health. Reducing smog depends on everyone, starting from bit by bit.
