Combating smog meets the requirements of what kind of society we are building

To control smog, the whole people must participate.

Each of us hates smog, but everyone is also a producer of smog. Chen Shiqiang, a member of the National Committee of the Chinese People's Political Consultative Conference, vice chairman of the Provincial Federation of Industry and Commerce, and chairman of Henan Hongchang Group Company, said.

Controlling smog is not only a matter for enterprises and enterprises, but must be participated in by the whole people. Chen Shiqiang believes that the control of haze and energy conservation and emission reduction are closely related, reflected in personal life, to develop a saving living habits, try to buy energy-saving household appliances, reduce the use of household appliances; Reflected in the production of enterprises, it is necessary to upgrade and improve production technology, consume less energy, and use more clean energy; In terms of transportation, it is necessary to drive less, promote the use of clean fuels such as natural gas, and improve automobile emission standards and fuel standards.

Strictly control the growth rate of cars.

Di Yingqi, a member of the National Committee of the Chinese People's Political Consultative Conference and dean of the Law School of Henan University of Economics and Law, said that statistics show that construction dust, soil dust and road dust account for 28% of Zhengzhou, and motor vehicle exhaust emissions account for 36%; The source carbon and biomass combustion sources and secondary air pollutants are about 21%; About 15% from regional transmissions.

It can be seen that the large-scale growth of cars is one of the main reasons for the aggravation of smog weather. Formulate an emergency plan in the case of heavily polluted weather, and clarify the conditions, procedures and division of responsibilities of the first department for emergency response. For example, establish a forecasting model for air quality pollution, and release the current pollution status to the public in a timely manner; During the haze weather, enterprises with heavy air pollution will take measures to stop production and limit production according to the specific situation.

The need to build stability in a harmonious society!

Haze is a mixture of "fog" and "haze", the former is formed by the condensation of water vapor in the air and then suspended in the air; The latter is formed by the suspension of a large number of particles, such as smoke and dust.

The particulate matter released from factory chimneys and car exhaust pipes varies in size, but all pose a deadly threat to human health. For example, larger particles can enter the lungs with breathing and attach to the lining of our lungs. This kind of small particulate matter has strong activity and is easy to adsorb toxic and harmful heavy metals or microorganisms; The smallest particles can also flow into the bloodstream through the alveoli and even into the brain, causing various changes in brain function.

Normally, the temperature of the atmosphere decreases with altitude, which is often referred to as "high altitude is not cold". When the climate is abnormal, the temperature of the upper air will be higher than or equal to the temperature of the lower air, forming a temperature inversion. At this time, the air at a higher temperature at a high altitude will inhibit the rise of soot and cause it to accumulate, resulting in haze.

In addition to man-made smoke and dust, the formation of haze is also inseparable from weather factors. Once an inversion layer appears in the atmosphere, it is like an extra cover in the sky, so that the smoke and dust that are continuously released have nowhere to flow.

In order to improve the haze weather, fog cannon trucks known as "smog removal artifact" have appeared on the streets of many cities in China. It uses high pressure to break up water droplets into smaller droplets, which are then ejected into the air by a fan to form a water mist. The soot particles then come into contact with the water droplets, gradually adsorb other soot particles, and finally settle under the action of their own gravity.

Environmental protection authorities have tested that the use of fog cannon trucks reduces the concentration of air in the area by 15 to 20 percent.

Nowadays, everyone is racking their brains to find a way to control the smog. However, the fog goes and returns, and there is no one-time solution to completely get rid of the smog, and it takes the joint efforts of several generations of us to see the results.

reducing the use of coal for residential heating; restricting private cars and developing public transport; Various measures such as building energy-efficient office buildings and using new energy sources are very effective in controlling smog, so let's all take active action to defeat smog together!

Haze is a state of air pollution, which is a general statement of the excessive content of various suspended particulate matter in the atmosphere. When the emission of fine particulate matter from human activities exceeds the capacity and carrying capacity of the atmosphere, the concentration of fine particulate matter will continue to accumulate, and if the weather conditions are relatively stable, it is prone to large-scale haze weather.

Haze is a weather phenomenon, fog is the condensation of water molecules in the air, and haze is due to the combination of various particles and gases in the air and water molecules, haze is a disaster for people, so we should pay attention to environmental problems.

Smog is a mixture of fog and haze, fog is formed by fog particles in the air suspended in the air, and haze is caused by a large amount of smoke and dust suspended in the air. Smog can be formed because of air pollution, exhaust emissions, industrial exhaust gases, etc.

It is true that smog is a state of air pollution, which is mainly composed of sulfur dioxide, nitrogen oxides and inhalable particulate matter, the first two of which are gaseous pollutants, and the last particulate matter is the main cause of aggravated haze weather pollution, which is combined with fog to make the sky instantly gloomy and gray. Readers who want to continue to understand whether smog is a state of air pollution can read on.

1. Haze is a combination of fog and haze, haze is common in cities, and many areas in China merge fog into haze together to hail for early warning and forecasting of disastrous weather phenomena, collectively known as "haze weather".

2. However, 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 called haze, and fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the ground.

3. In haze weather, some tiny particles in the air can lead to poor air circulation, and bacteria and viruses are more likely to gather and breed, when people are often in haze, the risk of inhaling bacteria and viruses will be greatly increased.

4. Haze entering the human body will damage endothelial cells for a long time, constrict blood vessels and increase blood pressure, and can activate platelets, increase the probability of thrombosis, and increase the risk of some diseases.

1. The air does not flow, so that tiny particles gather in the air, which is why the haze will dissipate as soon as the cold air comes.

3. Automobile exhaust emissions: There are more and more cars in the city, and it can be seen from the number of parking spaces that the more cars there are, the more exhaust emissions there are, and the air quality will naturally become worse and worse, resulting in haze weather.

4. The humidity in the air is too low, and people will bring up dust on the ground when they move.

Fog pollution.

It is a typical type of air pollution. Judging from China's existing legislation, many laws and regulations involve fog pollution.

These laws and regulations mainly include:

1) Air Pollution Prevention and Control Law. The legislative purpose of the Air Pollution Prevention and Control Law is to prevent and control air pollution, protect and improve the ecological environment and living environment, and promote sustainable social and economic development. The law takes note of the characteristics of China's energy structure, and in the second chapter of the law, it is specially titled "Prevention and Control of Air Pollution Caused by Coal Burning", which makes special provisions on the prevention and control of air pollution from coal combustion.

In addition, the law also makes many provisions on "prevention and control of pollution from motor vehicles and ships" and "prevention and control of waste, dust and foul odors". According to these provisions of the Air Pollution Prevention and Control Law, fog pollution is also the object of air pollution control, and the control of fog pollution is also one of the goals of the Air Pollution Prevention and Control Law;

2) 2013 Air Pollution Prevention and Control Action Plan. The plan is issued by the first country, is the new situation specifically for air pollution control and the overall plan formulated, the plan specifically put forward the need for comprehensive treatment, in order to reduce the emission of air pollutants, and specifically for industrial enterprises air pollution control, deepen non-point source pollution control, strengthen mobile source pollution prevention and control.

The plan also puts forward specific action plans for upgrading the industrial structure, improving technological innovation capabilities, accelerating the adjustment of energy structure, increasing clean energy, strict access to energy conservation and environmental protection, and optimizing the spatial layout of the industry. However, on the whole, the plan has an obvious "blueprint" color, and it is a national strategic air pollution prevention and control plan, rather than a normative document that sets rights and obligations.

The plan can set overall goals for air pollution control, straighten out ideas, and its enthusiasm should be affirmed;

3) Local regulations. In the face of the strong attack of fog pollution, some localities have also actively carried out legislation and formulated some local regulations. For example, the "Sichuan Province Gray Thunder Pollution Prevention and Control Implementation Plan", "Beijing Municipal Air Pollution Prevention and Control Regulations", "Lanzhou City Implementation of the Air Pollution Prevention and Control Law Measures", "Shanxi Province Implementation Plan for the Implementation of Air Pollution Prevention and Control Action Plan" and so on.

These local regulations combine local characteristics to make provisions on the control of fog pollution.

In addition, as a subordinate law of the "Air Pollution Prevention and Control Law", the relevant regulations formulated by the local government can also be regarded as an important part of the "Air Pollution Prevention and Control Law" or implementation rules, such as the "Nanjing Air Pollution Prevention and Control Regulations" and other provisions reflect the efforts of the local government to refine the superior law.

"Ambient Air Quality Standards", "Twelfth Five-Year Plan for Air Pollution Prevention and Control in Key Areas", etc., these policies are a series of policies issued by China's first government for haze, and you can also refer to the "Ministry of Environmental Protection Responds to Haze Prevention and Control (Hot Spot Interpretation and Dialogue)" in the policy encyclopedia, where there is a detailed interpretation of the haze policy. At present, China does not have a perfect legal system to deal with smog, and we still have a long way to go on the road to prevent and control smog, and we can adopt the methods of developed countries.

In 1956, the United Kingdom passed the world's first air pollution law: the Clean Air Act. The law stipulates that all power plants in the city of London will be relocated to the suburbs; Only smokeless fuels can be used in the prescribed urban areas; Large-scale renovation of residents' traditional stoves, and gradual introduction of central heating in winter to reduce the use of coal.

On this basis, a series of supporting local laws and regulations have been introduced across the UK. In 1968, the second edition of the Clean Air Act was enacted in the United Kingdom, which put forward higher requirements for factory emissions. In 1974, the Control of Pollution Act was enacted to address environmental issues in an all-round way by covering air, water, solid waste, and noise pollution.

There are many other laws in the UK regarding the control of air pollution, and these laws have been strictly enforced since they were enacted. Instead of engaging in a gust of wind, the control of smog in accordance with the law has become the foundation of permanent improvement of London's air quality.

The second is to adjust the industrial structure, London vigorously relocated and compressed traditional industries, especially manufacturing, from industrialization to "de-industrialization", and focused on the development of the service industry represented by the financial industry. By 1980, the share of total employment in the services sector as a whole had been reached.

The third is to improve public services, including the renovation of urban heating facilities, the development of public transportation, and the construction of large areas of green space. London attaches great importance to the construction of green spaces in urban planning, and in addition to large parks, all kinds of exquisite small and medium-sized green parks are scattered throughout the city. Although land is expensive in London, there are more green spaces than buildings and play an important role in purifying the air.

Through this series of measures, after nearly 30 years of efforts, London's air quality has improved significantly. By 1980, London had fog for only five days a year, and the haze had largely disappeared.

Before the haze is controlled, we have to be responsible for our own bodies and wear masks when we go out, Pu Weixin is a good choice, and professional anti-haze masks can be seen on Tmall.
