What is atmospheric pollution?

As we all know, the clean atmosphere is composed of 78%of nitrogen, 21%oxygen, 0.93%of rare gases, 0.04%carbon dioxide, and other substances of 0.03%.

The occurrence of pollution is mainly due to the entry of certain pollution substances in the process of human activities and the development of nature, especially energy combustion such as coal, industrial production, transportation, construction construction, straw open -air incineration, fireworks and firecrackers, etc. Sulfur dioxide, nitrogen oxide, volatile organic matter, ammonia, smoke, dust and other pollutants.

When the concentration and existence time of these substances in the atmosphere reaches harmfulness, causing damage to the ecosystem, which will affect the normal survival and development of human beings. These phenomena that cause harm to people or things are called atmospheric pollution.

How is air pollution formed?

The formation of pollution is actually a long -term and complex process. When the wind speed becomes smaller, the transmission of pollutants' horizontal transmission becomes slower, and the disadvantage of terrain blocking, pollutants often fail to spread in time, and air pollution is easily worse. When unfavorable meteorological conditions occur, if the pollutants generated by coal and living activities are as discharged into the atmosphere as ever, the pollution will continue to accumulate and spread it. Atmospheric pollution will be continuous Severe pollution of regional air will be formed.

How is the atmospheric environment resume prevention and control?

The atmospheric environment actually has self -cleaning and self -net ability. The self -purification capacity of the atmospheric environment can dilute and remove the atmospheric pollutants. The atmospheric self -purity ability is affected by the temperature layer, wind direction, wind speed, humidity, and landmark nature.

However, when temperature occurs, the vertical exchange of air will be hindered, and pollutants will be continuously diluted and mixed in the atmospheric environment below the inverse temperature layer. So the lower the temperature layer, the smaller the dilution of pollutants, the more serious the air pollution will be.

What do we do to prevent and control atmospheric pollution?

my country has long been formulated by legislation to prevent air pollution.

The country optimizes the industrial structure, rectify the "scattered pollution" enterprises, and forced industrial enterprises to meet the standards. At the same time, further optimize the energy structure, strictly control the use of coal, promote the elimination and transformation of coal -electricity coal -fired boilers, and focus on developing clean energy.

Not only that, the state and governments at all levels also specifically optimize the transportation structure and carry out special rectification of excessive discharge of diesel trucks. Simultaneously optimize the structure of land use and comprehensively govern the dust of the city. At the same time, inspection and inspection continuously strengthen inspections, and strictly supervise and manage according to law. Various methods and measures, they are working hard to achieve air quality and protect the public's health all the time.

What can our people do?

A good ecological environment is the most inclusive people's livelihood. Pay attention to air quality, and everyone is responsible for air pollution prevention and control. People should start with themselves, start small things around, advocate green travel, reduce pollutant emissions, practice simple life, develop electricity saving habits, pay attention to suspicious pollution discharge companies around them, report pollution behavior, and build beautiful China together.
