How to deal with the frequent problems of smog days?

The frequent problems of smog days may be caused by the exhaust gases produced during the combustion of fossil fuels being emitted into the atmosphere, and the country is now developing new energy sources to ban the energy provided by fossil fuels.

It is easy to block people's sight in haze days, so that people cannot see the road ahead, it is easy to cause safety accidents, endanger people's personal safety, and it is urgent to control haze.

I think it is a concentrated reflection of the imperfect laws and regulations, and the state may not have promulgated appropriate laws in time to restrict people's activities in hazy weather.

This can easily pose a threat to people's health, because there is inhalable dust in these hazes, and once inhaled by the human body, the consequences will be serious.

The cause of smog has not yet been discovered, and it will never be as simple as more cars and more factories. Twenty years ago, factories were all over the country, and the smog was serious? The earth is alive, and if there is life, there will be various forms that express health and discomfort.

Sandstorms were frequent in the early years, but now they are rare. Is it the tree species that are in the way? Apparently not.

Frequent smog, factory starts, construction site operations, car walking? Apparently it's not that simple. In fact, one day, the temperature dropped, the wind rose, and the sky was immediately high and cloudy.

Science is still to be studied**.

It is easy to block the driver's vision on a hazy day, and even if the lights are turned on, it is difficult to see the road clearly, which can easily cause traffic accidents and endanger people's lives.

People should not complain in the face of smog weather, but should think about preventing smog, and everyone should contribute to the prevention and control of haze, rather than choosing to sit idly by.

The formation of haze is caused by poor ventilation and random construction to block the air duct.

The frequent occurrence of haze days also gives people a certain warning, warning people to face the haze rationally and join the team to prevent and control the haze.

The Three-North Shelterbelt blocked the wind. In the seventies and eighties, there was a north wind blowing at both ends for three days in winter, and there was almost no haze at that time. The topography of our country is high in the west and low in the east, and because the shelterbelts are in the northwest, the cold winds from Siberia in winter are blocked, and the strong winds become small winds, and the small winds are no longer windy to us.

Another reason is that in recent years, the buildings in the city have become higher and denser, because this is not a city, but a whole country, blocking the wind that should come, causing today's smog to become more and more serious.

This is also a fluke mentality, people think that their ability to defeat the haze is at work, and underestimate the harm of the haze.

I think it may be that some people are still taking advantage of the loopholes in the law, the state explicitly prohibits the burning of straw, but there are still many people who secretly burn straw and turn a blind eye to the environmental problems caused.

This is the reason for the fireworks, which is because fireworks are set off for a few days during the Chinese New Year, which causes smog to appear from time to time throughout the year (manual funny.

This is also a reflection of people's quality, some drivers still drive fast in hazy weather, do not consider the consequences, and overly believe in their own skills.

In order of power reduction is - industrial boiler. Ten thousand cooking smoke. Heating in winter. Car exhaust. Road dust. Stubble burning. Outdoor barbecue, etc.

Whether it is China or the world, the haze is decreasing year by year!

But it is still necessary to be highly vigilant. We will continue to explore and improve the gas emissions that pollute the environment by particulate emissions, actively participate in the world governance system, and be an advocate and pioneer. Never sabotage the fight.

The haze weather has a direct cause for the dump truck pulling the earthwork on the construction site, and the dump truck runs up near the construction site and even the dump site is dusty, and the relevant departments should control it.

The main culprits of the smog are:

Fog, there is no haze without fog, and fog is the carrier of haze.

Diesel vehicles emit more than ordinary small factories, and the number of diesel vehicles is equivalent to how many factories are running on the road.

Construction sites. Flying dust caused by substandard roads.

Warm in winter.

Smog is traffic. Five rings, six rings, seven rings, eight rings. The denser the transportation network in the basin, the more severe the smog and dust.

In the words of **, the weather is not easy to cause the spread of pollutants, but there is haze everywhere in the country, and there are places to disperse!

I am a post-70s generation, and I remember that the haze appeared within a few years after the successful afforestation in the Great Northwest! Humans have changed the direction of the air flow and broken the rules of nature, so the haze has appeared! Analyze each individual.

Smog should not be a reason to limit people's income from economic development! Only when the quality of life of the people is guaranteed, the moral character of the people will also be improved. It is still a problem for the masses to eat and heat, who cares if you are environmentally friendly or not.

After all, China is still a developing country, and there is still a big gap between it and developed countries!

Smog is a product of the process of weather change. Now that the burning of straw has been banned for several years, why is there still a haze phenomenon, there is such a phenomenon everywhere in the earth, how can experts explain it?

Thirty years ago, I used to go outside for breakfast in winter to find a sunny place, and it felt very warm, but now it is difficult to see the sun in the morning, and there were not so many cars at that time

I think we should reduce the number of trips by car and develop public transport vigorously.

Pollution from small and micro enterprises, coal burning for heating, firewood for cooking, open burning of straw, barbecue restaurants, and farms in the north are caused.

Buildings are still being developed and built all over the country, and there are fewer and fewer green spaces! Polluting enterprises from all walks of life, more and more exhaust emissions from vehicles!

I wonder if there was no fog 30 years ago? It's all smog right now...

The people of Guanzhong, Shaanxi Province said that they couldn't breathe anymore!

The haze is good, you don't have to work... Hahahaha.

It has little to do with diesel cars.

1. The relative humidity of the air near the ground is relatively large, the dust on the ground is large, and the people and vehicles on the ground stir up the dust;

2. There is no obvious cold air activity, the wind is small, and the atmosphere is relatively stable, due to the non-flow of air, the tiny particles in the air accumulate and float in the air;

3. The sky is clear and cloudless, which is conducive to radiation cooling at night, so that the air with relatively high humidity near the ground is saturated and condensed to form fog;

4. Automobile exhaust is the main pollutant emission, in recent years, there are more and more cars in the city, and the emission of automobile exhaust is a factor of haze;

5. Secondary pollution produced by the factory;

6. CO2 and other pollutants emitted from heating in winter.

Introduction to haze weather.

Haze weather is a state of air pollution, haze is a general expression of the excessive content of various suspended particulate matter in the atmosphere, especially the aerodynamic equivalent diameter of particles less than or equal to microns) is considered to be the "culprit" of haze weather. With the deterioration of air quality, the phenomenon of haze weather has increased, and the harm has increased. In many parts of China, haze weather phenomena are combined with fog as early warning and forecasting of severe weather.

Collectively referred to as "haze weather".

The formation of haze is caused by both meteorological factors and other reasons such as pollution emissions. Unfavorable meteorological conditions are a direct inducement to the formation of haze.

Cause. North China is affected by the convergence of cold and warm air, and it is very prone to heavy weather.

As a result, air pollutants accumulate and air quality deteriorates, resulting in haze. Large pollutant emissions are the root cause of haze formation, according to environmental protection.

According to bureau statistics, half of the PM2 in the country .5 are from vehicle exhaust and construction emissions.

In fact, China's environmental protection laws are one of the most in the world, but there are long-term laws and regulations that are incomplete and the process is not complete.

The perfect situation has led to the further deterioration of China's air environment.

There are three main reasons for the formation of haze:

1. The physical base source for the generation of particulate field dust. China has the largest Loess Plateau in the world, and its soil texture is the most prone to the formation of particulate dust particles.

2. Dust caused by poor movement. For example, if mud flows onto the road after rain or splashing water on the soil in the middle of the road and on the corner of the street, after an hour of dry bucket ignition, it will cause a lot of dust to be spun by the wheels, and even if these particulate matter dissolve back to the ground, it will be thrown over the empty city again due to the continuous driving of cars.

3. The dust-based source and the motion difference process are concentrated in a certain spatial range, and the particles eventually accumulate with the nodules of water molecules to form haze. At present, among the more than 350 cities in the Loess Plateau region of China, the stock of haze structure is quite abundant.

In general, smog is usually caused by a combination of multiple pollution sources, mainly composed of sulphur dioxide, nitrogen oxides and respirable particulate matter, which combine with the fog and make the sky instantly gloomy and gray. Its sources include automobile exhaust, industrial emissions, construction dust, garbage incineration, volcanic eruptions, etc.

There are several reasons for the formation of haze weather:1The main factor is when the atmospheric air pressure is low and the air is not flowing. Due to the non-flow of air, tiny particles in the air accumulate and float in the air.

2.The ground is dusty, the air humidity is low, and the people and traffic on the ground stir up the dust.

3.Automobile exhaust is the main pollutant emission, and in recent years, there are more and more cars in the city, and the emission of automobile exhaust is a factor of smog.

4.Secondary pollution produced by the factory.

5.Pollutants such as CO2 emitted from heating in winter.

Answer: Haze weather mostly occurs in basins or places with relatively low terrain. The biggest reason is that the air pressure in the atmosphere is low, and the air does not flow. And the non-flow of air causes tiny particles in the air to accumulate and float in the air.

2. In some places where the ground is dusty and the air humidity is low, the people and traffic on the ground stir up the dust. 3. Due to the development of the economy, people have more and more private cars. Vehicle exhaust has become a major pollutant emitted, so the emission of vehicle exhaust is a factor of smog.

4. Another important reason is that the emissions produced by the factory are not properly handled, resulting in secondary environmental pollution. 5. In some areas in the north, it is necessary to rely on coal to rely on coal for heating in winter, and the combustion of coal emits a large amount of CO2 and other pollutants.

So what harm does smog do to people's bodies? According to doctors, the effects of air pollution on lung cancer are continuous and chronic. At the same time, foreign studies have also shown that toxic particulate matter in the air on hazy days is one of the important causes of cardiovascular diseases.

In addition to cancer, smog days are harmful to the heart. Particulate pollutants on hazy days can not only cause myocardial infarction, but also cause myocardial ischemia or injury. At the same time, hazy days may also trigger common respiratory diseases such as acute chronic arteronism, emphysema, asthma, bronchitis, rhinitis, and upper and lower respiratory tract infections.

Scientists have shown that for every 10ug per cubic meter of inhalable particulate matter in humans, the risk of respiratory diseases increases, cardiovascular disease rises, and the mortality rate due to smog increases by 1% every day. Therefore, haze weather is the health enemy of all patients with cardiovascular diseases, for the elderly with respiratory diseases and cardiovascular diseases, it is best not to go out in the haze day, nor can you exercise in the morning, otherwise it may induce illness, or even heart attack, endangering their own life safety.

In hazy weather, to do a good job of self-protection, first of all, be sure not to be outdoors, reduce the time outdoors, reduce the intensity of outdoor activities. In particular, people with chronic diseases such as cardiovascular and cerebrovascular diseases should reduce outdoor activities on smog days. Second, pay attention to improving indoor air quality.

In hazy weather, the air quality indoors and outdoors is not too good. Therefore, it is also necessary to pay attention to the improvement of indoor air quality. Finally, in the case of having to go out, you should also pay attention to strengthening self-protection and choosing the right dustproof.

The causes include car exhaust, factory emissions, and gases emitted when people build stoves in winter.
