Haze's Harm to Nature

Haze is harmful to nature. A smog locked the good mood of the whole city. We should all know that fog or haze is a disastrous weather, and smog is very harmful to people's health. Understand the harm of smog to nature.

Haze's harm to nature 1 causes of haze weather

1, human reason

① Automobile exhaust. Automobile exhaust is the main component of smog particles.

(2) Waste gas generated by burning coal for heating in winter in the north.

(3) Waste gas discharged from industrial production. For example, metallurgy, kilns and boilers, electromechanical manufacturing, automobile repair and paint and building materials production produce a lot of waste gas from kiln combustion.

④ Dust from construction sites and road traffic.

⑤ Particles can grow. The particle size of bacteria and viruses is equivalent to PM0,1~ PM2,5. When the humidity and temperature in the air are appropriate, microorganisms will attach to particles, especially oil fume particles. After the microorganisms absorb the oil droplets, they will be transformed into more microorganisms, which will increase the number of biological toxic substances in the smog.

⑥ Dust "smog" will also be produced in home decoration. Indoor dust is pervasive, which is not only harmful to the health of staff and users, but also increases the cleaning burden. When the dust is serious, it also brings many hidden dangers to the decoration project.

2. Climatic reasons

① The phenomenon of static wind in the horizontal direction increases. The higher the buildings are built in the city, the obstruction and friction of airflow passing through the urban area will be obviously weakened. The increase of static wind phenomenon is not conducive to the diffusion and dilution of suspended particles in the atmosphere, and it is easy to accumulate around urban areas and suburbs.

② The inversion temperature appears in the vertical direction. The inversion layer is like a pot cover over a city. This inversion phenomenon that the upper air temperature is higher than the lower air temperature limits the vertical movement of the lower air, making it difficult for suspended particles in the air to drift to the upper air and be blocked at the lower air and near the ground.

③ The increase of suspended particles and organic pollutants in the air. With the growth of urban population and industrial development, the number of motor vehicles has surged, resulting in a large increase in pollutant emissions and suspended solids.

The influence of haze weather

1, harm to human body

Haze can affect people's respiratory system, causing acute rhinitis and acute bronchitis. For patients with chronic respiratory diseases such as bronchial asthma, chronic bronchitis, obstructive emphysema, and chronic obstructive pulmonary disease, smog weather will make the condition acute or acute.

② Haze days have a serious impact on cardiovascular and cerebrovascular diseases, which will hinder normal blood circulation and lead to cardiovascular diseases, hypertension and coronary heart disease.

(3) Hazy weather will also lead to the weakening of ultraviolet rays in the surface layer, which can enhance the activity of infectious bacteria in the air and increase infectious diseases.

4 smog is not conducive to children's growth. In foggy days, due to the decrease of sunshine, insufficient ultraviolet radiation for children, insufficient production of vitamin D in the body, and greatly reduced absorption of calcium, rickets in infants and young children will be seriously caused, which will slow down the growth and development of children.

2. Impact on ecological environment and traffic.

① In foggy days, traffic jams and traffic accidents are easily caused due to poor air quality and low visibility. In daily driving, you should observe the road conditions to avoid danger.

② In foggy weather, the light is seriously insufficient, and the ultraviolet rays near the bottom are obviously weakened, so it is difficult to kill the bacteria in the air, thus greatly increasing the probability of suffering from infectious diseases.

③ Haze weather has an important impact on roads, railways, aviation, shipping, power supply system and crop growth. Fog and haze will cause air quality decline, affect the ecological environment and bring great harm to human health.

Haze is harmful to nature 2 1, and it is harmful to respiratory system.

The composition of smog is very complex and small, which is invisible to the naked eye, but it is very lethal, mainly mineral particles, sea salt, sulfate, nitrate, organic aerosol particles, fuel and automobile exhaust. It will directly enter and adhere to the human respiratory tract and alveoli.

Once it enters the human body, it will attack the human body, especially parents with chronic respiratory diseases such as bronchial asthma, chronic bronchitis, obstructive emphysema and chronic obstructive pulmonary disease, which can cause acute attack or acute exacerbation. Long-term exposure to this environment will also induce lung cancer.

2. Harm to cardiovascular system

Hazy days also have a serious impact on cardiovascular and cerebrovascular diseases, which will hinder normal blood circulation, lead to cardiovascular diseases, hypertension, coronary heart disease, cerebral hemorrhage, and may also induce angina pectoris, myocardial infarction and heart failure. In addition, the low air pressure in dense fog will also affect people's mood and make people feel irritable. With the fluctuation of mood, blood pressure will also rise, which may lead to stroke and myocardial infarction. Therefore, patients with cardiovascular and cerebrovascular diseases must take medicine on time and be careful to deal with this "environmental enemy".

3. Weakening ultraviolet rays leads to calcium deficiency.

Hazy weather will lead to layers of suspended matter in the air, which will weaken the intensity of ultraviolet rays reaching the ground. Some people are thinking, isn't this better? You can stop tanning. On the other hand, the weakening of ultraviolet rays, insufficient ultraviolet irradiation and insufficient vitamin D production in the body greatly reduce the absorption of calcium, which has the greatest impact on children. If it is serious, it may cause rickets in infants and slow down the growth and development of children. Do you still think this is a good thing?

4, causing bacterial diseases

Because of the smog, the sun can't shine on the earth, or the sunlight is very weak. We all know that the sun has a certain bactericidal effect. Once Grandpa Sun is away from our grandmother, bacteria, viruses and microorganisms on the surface of the earth will multiply rapidly, and their wanton behavior will cause some allergic diseases to the human body.

5, affect mental health

Ask yourself, will your mood follow the weather? I believe many people are no exception, because many things complement each other. If it is sunny that day, people's mood will suddenly get better. This is not speculation, but people's real thoughts and elegance! Experts point out that continuous foggy days have an impact on people's psychology and body. Psychologically speaking, foggy days will give people a feeling of depression, stimulate or aggravate the state of psychological depression, and lack vitality in doing things.

6. Cancer. The risk increases.

As we all know, the probability of smokers suffering from lung cancer is 60% higher than that of ordinary people, which is a very shocking figure; But today's smog is even more terrible. Expert data show that smog contains more harmful particles, and smog is more likely to cause cancer than smoking. You can imagine what kind of concept this is!

7, affecting traffic safety

It is believed that when haze weather occurs, the visual visibility is very low, which will lead to many traffic accidents. At the same time, it is easy to cause traffic jams.

Haze's Harm to Nature 3 Method 1: Wear a hat.

In smoggy weather, the ability of hair to absorb pollutants can not be underestimated, so wearing a hat can solve this small trouble before going out. If it is not well protected, it may damage your health.

Method 2: Wear a mask.

Although wearing a mask cannot guarantee that 100% pollutants will not enter the oral cavity or respiratory tract, wearing a mask is another protective barrier. Therefore, wearing a mask is a preventive measure. After all, good health is the capital of the revolution.

Method 3: Wear long clothes.

Don't think that long skirts are heavy and it is difficult to exercise muscles. However, it is worth noting that compared with short clothes, long clothes greatly reduce the contact area between polluted air and the body and have more protection.

Method 4: Reduce the time of outdoor activities.

In this foggy weather, due to the large coverage of harmful air, the frequency of going out is minimized. If you really want to go out, it's best to walk in small steps, breathe peacefully, and don't worry.

Method 5: Wash your hands and face indoors.

When you are outdoors, in this foggy day, even if you are fully armed, it is not pervasive, so more or less harmful substances may come into contact with your skin, so wash your hands and face before entering the house.

Method 6: Breathe through the nose

There are always some harmful substances in the air in foggy days. If you breathe through your mouth, what harmful substances will enter your body, but breathing through your nose is different. The nose hair and mucus in your nose will absorb some, if not all, harmful substances in the air, at least not all.

Method 7: enter the house and skillfully open the window.

In foggy days, there is some stale air everywhere outside, but there is no way. After the indoor oxygen is absorbed by people, there is only carbon dioxide, but it is not carbon dioxide. Therefore, you can open the window at noon, but you have no choice.

Method 8; go to bed early

Go to bed early in such bad weather, and don't stay up late to play mobile phone online, which is not good for your health. Moreover, going to bed early is an effective way to slow down breathing, and it is also the best way in this foggy weather.

Method 9: Drink plenty of water.

Water is an indispensable part of our life, so when we are free. Drinking hot water is still very good for your health, knowing that your body will not be short of water.
