The dangers of smog and the views on preventing and controlling smog

The dangers of smog and the views on preventing and controlling smog. With the over-exploitation and construction of the natural environment by humans, our lives have become There is haze in the environment. Smog is more common in some big cities, especially. Let’s take a look at the dangers of smog and how to prevent and control it. The dangers of smog and opinions on preventing and controlling smog 1

The dangers of smog

1. Impact on the respiratory tract

The harmful fine particles and toxic substances contained in smog The substance is easily inhaled into the human body and enters the throat and bronchi directly from the nostrils, interfering with gas exchange in the human lungs. When it enters the throat, it can easily cause inflammation in the human body. When it affects the bronchi, it will affect the normal gas exchange in the lungs, and can easily cause respiratory diseases such as acute rhinitis, bronchitis, bronchial asthma, etc. If you suffer from Patients with respiratory diseases are prone to relapse and aggravation of their condition during hazy days.

2. Affects the cardiovascular and cerebrovascular systems

There are many pollutants in the air during haze weather, especially low-pressure weather, which can easily affect the normal blood circulation of the human body and easily induce heart disease. , hypertension, coronary heart disease and other diseases. Especially when going out, the cold outdoors can easily cause blood vessels to expand and contract with heat, leading to increased blood pressure.

3. Carcinogenic

There are as many as 20 types of harmful fine particles and toxic substances in the fog during haze weather, among which many aromatic hydrocarbons and other substances with carcinogenic effects may cause The risk of developing cancers such as lung cancer in the body is higher, especially in places with severe industrial pollution.

4. Affects mental health

In haze weather, the light is poor and the low air pressure presses on people’s heads, which can easily cause mental fatigue and emotional distress. Depression and pessimism are easy to appear, which can easily lead to mild depression.

5. Impact on traffic

In haze weather, the fog in the atmosphere is heavy, the visibility of the field of vision is low, and the air quality is poor. The human body's vision is easily blurred, which can easily cause traffic congestion. , and even cause traffic accidents.

Preventive measures for smog

1. Ensure indoor air quality. People stay indoors for a long time, and the indoor air quality will seriously affect people's health. You can choose a negative ion air purification device. Negative ions can combine with particulate pollutants in the air to condense and settle. Ecological negative ion generation chip technology can improve purification. efficiency, achieving ultra-fine purification. The pollutants that enter the room are mainly ultrafine particles such as PM2, 5, and PM1, which are difficult to filter out with ordinary air purifiers.

2. Wear a mask when going out. It is best to avoid staying outdoors for a long time in hazy weather. It is best to wear a mask if you need to go out. Masks can prevent poisonous smog from invading the human body through the mouth and nose to a certain extent and reduce the harm of smog to the human body. When choosing a mask, try to choose a cotton mask. You can rinse your nasal cavity with clean water after returning from going out.

3. Reduce ventilation through doors and windows. To prevent damage caused by haze, we should pay attention to reducing the time of opening windows for ventilation. Doors and windows should be closed tightly if possible. This is because a large amount of pollutants in the air are difficult to disperse in haze weather. If you open doors and windows, it is easy for pollutants to enter the room and cause physical discomfort. The harm of smog and the views on preventing and controlling smog 2

The harm of smog

1. Injury to the lungs

Haze days have the greatest impact on the respiratory system. It has become common knowledge for most people. The respiratory system has the most frequent contact with the external environment, and the contact area is large. Hundreds of atmospheric particles can directly enter and adhere to the upper and lower respiratory tract and lung lobes of the human body, and most of them will be inhaled by the human body.

2. Injury to the heart

The Harvard School of Public Health has proven that particulate pollutants in hazy days can not only cause myocardial infarction, but also cause myocardial ischemia or damage. The United States surveyed 25,000 people with heart disease or poor heart conditions and found that when PM2 and 5 increase by 10 micrograms cubic meters, the patient's mortality rate will increase by 10% to 27%.

3. Injury to blood vessels

There are many pollutants in the air and low air pressure in haze days, which can easily induce acute attacks of cardiovascular diseases. When there is heavy fog, the water vapor content is very high. When people do outdoor activities and exercise, sweat is not easily discharged, causing chest tightness and increased blood pressure.

4. Damage to the skin

The skin also has a breathing function. In clean air, the skin will be very comfortable and moisturized, but if it is in a very dirty environment, the skin will be very uncomfortable. Comfortable.

5. Harmful to the brain

Smog not only damages the organs, but also affects the nervous system invisibly. Zhong Nanshan once introduced that the 65th Annual Meeting of the American Geriatrics Society concluded that if PM2 and 5 in the air increase by 10 micrograms cubic meters, human brain function will decline by 3 years.

6. Damage to the reproductive and urinary system

The impact of haze on semen quality is mainly manifested in the later stages.

Inhalable substances in the haze enter the human blood circulation and gradually accumulate in various organs of the human body, including the scrotum in the semen factory.

Methods to prevent haze

1. Go out less: Going out less is the most effective way to protect yourself. If you must go out, don't ride a bicycle, avoid rush hour traffic and roads with lots of driving, to avoid inhaling more chemicals. It is also best not to drive a private car and take public transportation more often to contribute to reducing PM2 and 5.

2. Wear a mask when going out: If you go out, you can wear a mask, which can effectively prevent dust particles from entering the body. Cotton masks are best because some people are allergic to non-woven fabrics, while most people are not allergic to cotton masks and they are easy to clean.

3. Good personal hygiene: Wash your face, gargle, clean your nasal cavity in time when you go indoors, and remove pollutant residues on your body to prevent the harm of PM2 and 5 to the human body.

4. Open windows less often in hazy weather: Experts say that in hazy weather, try not to open windows. If you really need to open a window for ventilation, you should try to avoid the peak hours of morning and evening smog. You can open the window a little for ventilation, and the time is preferably half an hour to an hour at a time. The dangers of smog and views on smog prevention 3

10 suggestions to help you fight against smog

1. Try not to go out, especially outdoor morning exercises

When fogging occurs, the air pressure is low and the oxygen content in the air decreases, which can easily make people feel chest tightness and discomfort. Humid, cold fog in the morning can easily cause vasospasm, blood pressure fluctuations, increased heart load, etc. It is best not to go out in foggy weather, and it is not advisable to exercise to avoid angina pectoris, cerebral hemorrhage and other diseases.

2. Wear a professional dust mask when going out

Because the fine particles are too small, the cotton gauze masks on the market only have a dust-proof effect and cannot block PM2 and 5. KN90, KN95, and N95 level dust masks approved by the state can filter fine particles to a certain extent and have a good protective effect against most bacteria and germs.

3. Wash immediately after returning from going out

When returning from going out in hazy weather, you should immediately wash your face, nasal cavity and exposed skin, and put on clean clothes to avoid bringing fine particles indoors , aggravating indoor air pollution.

4. Eat a light diet and drink more water

During the haze season, patients with cardiovascular disease should eat a light diet, drink more water, eat more fresh vegetables and fruits, and eat less irritating foods. . You can eat more pear, orange, radish, loquat, lily, lotus seeds and other foods that can clear the lungs and reduce phlegm.

5. Drink appropriate tea that “clears and removes lung dust”

Tong Platycodon tea, Tong Shen tea, Tong Platycodon granules, Platycodon soup, etc. have the functions of clearing fire and filtering lung dust, and can enhance The ability of alveolar cells to expel toxic fine particles effectively assists the body in expelling PM2, 5 particles and other harmful substances accumulated in the body.

6. Take appropriate medications

Patients with cardiovascular disease can take some cardiovascular protective drugs under the guidance of a doctor to protect the vascular endothelium and inhibit vasospasm. Stabilize plaque, prevent plaque rupture, prevent myocardial infarction and stroke, and protect heart health from dense fog.

7. Open fewer windows in hazy weather

People spend 70% to 90% of their time indoors every day, so the harmful effects of indoor PM2 and 5 are greater. It is wrong to close the doors and windows in hazy weather because indoor air needs to be circulated. However, you should not open windows for ventilation in the morning and evening, because the pollution is heaviest at this time. It is better to open windows for ventilation after the sun comes out (around noon).

8. Smoking less or not smoking

Cigarette smoke contains a large amount of PM2 and 5, which have direct and indirect harm to the human body. You should smoke less or not smoke. If you can't stop people around you from smoking, you should try to stay away from the smoky environment.

9. Properly plant green plants

Green plants with relatively large leaf areas such as pothos, fishtail sunflower, dieffenbachia, and lucky bamboo can absorb harmful gases and adsorb PM2 and 5, which can reduce Concentration of respirable particulate matter in indoor environments.

10. Use equipment to remove dust

You can use an air purifier to filter PM2 and 5, or you can use an ultrasonic atomizer, indoor water curtain, pool, fish tank, etc. to absorb hydrophilic particles in the air PM2, 5, purify the air.
