What are the hazards of smog?

What are the hazards of smog? With the deterioration of air quality, smog weather began to appear, and smog weather began to appear in many places in China. This weather is very bad. What are the hazards of smog to share with you?

What are the hazards of smog 1 1 and its harm 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 change with 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. The risk of cancer will increase.

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.

What are the hazards of smog? 2. Ways to prevent smog

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.

What are the hazards of smog? 3 Suggestions for controlling smog.

First, reduce nitrogen oxides. The "gun ban order" was fully implemented in urban and rural areas throughout the country, and electronic firecrackers were used instead of firecrackers. As we all know, the inhalable particulate pollutants produced by fireworks and firecrackers. Xiamen, a national civilized city, should completely ban the discharge of fireworks and firecrackers within its jurisdiction (including Tong 'an, Xiang 'an, Jimei, Xinglin and Haicang), especially the Tzu Chi Cultural Festival held in Haicang every year, and should implement normal management to set a model of "no gun order" for urban and rural areas throughout the country.

Second, reduce automobile exhaust emissions and road dust pollution. Establish a more perfect public transportation system, innovate the development mode of urban transportation, improve the proportion and comprehensive efficiency of public transportation, and further reduce bus fares to reduce the use of private cars; Advocate and encourage the general public and government workers to take public transport and government shuttle buses, drive as few cars as possible and reduce exhaust emissions; Organs, enterprises and institutions should minimize the use of buses and reduce the pollution of smog weather without affecting their work. Specific measures: First, half of the existing urban roads are dedicated to public transportation, so that the bus road resources are sufficient, the traffic speed is accelerated, public transportation is convenient, cars are difficult to drive and parking is expensive; The second is to put in a large number of buses and scientifically lay out the sites. For example, stop at every stop, point-to-point, long-line segmentation, less turning and more straight lines. Combined with scientific dispatching measures, the riding peak can be stabilized and the maximum convenience can be realized. Third, it is necessary to reduce or cancel intersections in traffic-restricted sections such as no left and no right, reduce the amount of bus detours, and save time and energy consumption. Only such convenient public transportation can curb the rapid growth of cars, delay the investment in Xiamen's access to the island bridge and tunnel, and reduce the traffic pressure;

Three, take more stringent measures to control the pollution of the construction site and muck transportation. All construction projects with dust will be stopped first and then started after treatment. Dregs transportation must be watered before loading and unloading.

Four, strengthen the management of catering enterprises and barbecue stalls. Urban law enforcement departments should speed up the ban on roadside barbecue stalls and reduce the pollution of oil smoke to the surrounding environment and atmosphere.

Five, leading the emission reduction of nitrogen oxides with scientific and technological innovation. Domestic automobile factories and oil companies should pay more attention to technology updating, product upgrading and new technology research, so that cars emit less tail gas; At the same time, it is necessary to speed up the research on the development and utilization of new energy and renewable energy such as bioenergy and green energy, and accelerate the development of clean energy such as hydropower, wind power and solar energy; Accelerate the development of domestic natural gas, increase the scale of natural gas utilization, implement "replacing coal with gas" and "replacing oil with gas", promote the upgrading of energy consumption structure, and increase the structural proportion of non-fossil energy; Implement the development mode of combining centralization and decentralization, develop renewable energy, and ensure that wind power and solar power are given priority to the Internet.

Six, based on the west, west to east power transmission. Thermal power plants will be built in Shanxi, Shaanxi, Mongolia, Ningxia and Xinjiang, and then electric energy will be transported to the central and eastern regions ravaged by smog on a large scale through advanced transmission technologies such as UHV and smart grid. Of course, the western region should also control the pollutant emissions and environmental capacity of thermal power plants. This is not only a way to reduce the pressure of coal railway transportation, but also an effective way to solve China's energy problems and control smog.

Seven, speed up the revision of China's "Environmental Protection Law" and "Air Pollution Prevention Law" and other laws and regulations. Effectively solve practical problems such as compound air pollution brought about by the acceleration of industrialization, and minimize the pollutant emissions of large enterprises. All levels should strengthen leadership and implement responsibilities, and environmental law enforcement should always maintain a high-pressure situation. We will improve the accountability system for ecological environmental protection and the compensation system for environmental damage, and focus on solving problems such as inadequate responsibility, insufficient protection of public environmental rights and interests, and inadequate punishment for environmental violations. In addition to laws to follow, it is more important to abide by them, enforce them strictly, and punish those who violate the law, and seriously deal with acts of inaction and chaos, so that polluters dare not play with environmental protection. Ensure that the haze weather is effectively curbed.

Eight, pay close attention to improve the economic policy and price tax system. Take measures to improve economic policies such as environment, finance and taxation as soon as possible, make full use of economic leverage, and guide enterprises to accelerate the pace of transformation and upgrading. Strictly restrict loans and listing financing of environmentally illegal enterprises, and guide banks to increase credit support for air pollution prevention and control projects.

Nine, strengthen the propaganda of smog science knowledge and scientific prevention and control. Let the masses treat smog rationally and treat it rationally. Change the way of production and life, and truly take the road of green and low-carbon sustainable development.
