Content of handwritten newspaper on smoke control

1, the difference between fog and haze

Haze, fog, haze. But fog is fog, haze is haze, and the difference between fog and haze is very big. Fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the near-surface air, which mostly appears in autumn and winter and is the product of water vapor condensation (or condensation) in the near-surface air. The existence of fog will reduce air transparency and worsen visibility. If the' horizontal visibility' of the target is reduced to less than 1000 meters, the weather phenomenon of water vapor condensation (or condensation) suspended in the air near the ground is called fog. The phenomenon that the horizontal visibility of the target is 1000- 10000 meters is called light fog or haze. When fog forms, the atmospheric humidity should be saturated. If there are a lot of condensation nuclei, the relative humidity may not reach 100%. Because the light scattered by fog composed of liquid water or ice crystals has a great relationship with wavelength, the fog looks milky white or bluish white and gray.

Haze is composed of particles such as dust, sulfuric acid, nitric acid and organic hydrocarbons in the air. It will also make the atmosphere turbid, blur the vision and worsen the visibility. If the horizontal visibility is less than 10000 meters, the visual distance obstacle caused by this non-aqueous aerosol system is called haze or haze.

2. Smoke-related diseases

(1) upper respiratory tract infection

The persistent smog weather has enveloped more than 65,438+00 provinces in China. In foggy weather, a large number of harmful substances such as dust particles and smoke particles float in the air, which will cause harm to human respiratory tract. There are a lot of particles, dust, pollutants and viruses floating in the air. Once inhaled by the human body, it will stimulate and destroy the respiratory mucosa, dry the nasal cavity, destroy the defense ability of the respiratory mucosa, and bacteria will enter the respiratory tract, which is easy to cause upper respiratory tract infection.

(2) Bronchial asthma

The air pollution in foggy days is heavier than usual, and bacteria and viruses often exist in the air, which is easy to lead to the spread of infectious diseases and the occurrence of various diseases. In particular, air pollutants in cities are not easy to spread, which aggravates the toxicity of sulfur dioxide, carbon monoxide, nitrogen oxides and other substances and will seriously threaten people's lives and health. In foggy days, dust and smoke are floating in the air, and dust mites may also be suspended in the fog. Inhalation of these allergens by patients with bronchial asthma will stimulate the respiratory tract and cause asthma symptoms such as cough, sulking and poor breathing.

(3) Lung cancer

Professor Kan Haidong from the School of Public Health of Fudan University said that the incubation period of lung cancer ranges from several years to decades, and children's childhood lung cancer may be related to genetic factors and gene mutations. However, compared with adults, children's height determines that they are indeed more susceptible to automobile exhaust and road dust, which is recognized by the medical community. Because children's breathing zone is just close to the height of waste gas, at the same time, children's exposure per unit weight is higher than that of adults, which leads to their higher susceptibility, so they are more susceptible to pollution gases such as waste gas and smog. In addition, children's body organs are not fully developed, and the invasion of polluted gas causes more harm.

(4) Conjunctivitis

According to experts, particulate matter attached to the cornea in foggy days may cause keratitis and conjunctivitis, or aggravate the condition of patients with keratitis and conjunctivitis. Patients with keratitis and conjunctivitis

There is a significant increase, including the elderly and children, as well as office workers who are facing the computer all day. Everyone has the same situation: dry eyes, soreness, tingling, redness and allergies.

(5) Children's rickets

The preliminary study found that the smog weather not only led to an increase in the incidence/hospitalization rate of respiratory diseases, but also had some indirect effects on human health. The appearance of haze will weaken ultraviolet radiation. If smog often occurs, it will affect the synthesis of vitamin D in the human body, leading to

Children have a high incidence of rickets, and the activity of infectious bacteria in the air is enhanced.

3. Self-protection in haze weather

(1), open the window less in foggy days.

It is not recommended to open the window for ventilation in the morning and evening in foggy weather. It's best to wait until the sun comes out before opening the window for ventilation.

(2) Wear a mask when going out

You can wear your mouth when you go out.

The cover can effectively prevent dust particles from entering the body. Cotton masks are the best because some people are allergic to non-woven fabrics, while cotton masks are generally not allergic and easy to clean. When you come back from going out, you should wash your face and expose your skin immediately.

(3) Drink more Tung Platycodon grandiflorum tea, Tung Ginseng tea, Tung Platycodon grandiflorum granules and orange stem soup.

"Qingfei Dusting" tea with platycodon grandiflorum tea has the functions of clearing fire and filtering lung dust, which can significantly enhance the ability of alveolar cells to discharge toxic fine particles and effectively assist the human body to discharge harmful substances such as PM2.5 particles accumulated in the body. For details, please refer to Tongplatycodon grandiflorum tea and orange stem soup of Baidu Encyclopedia.

(4) Appropriate vitamin D supplementation.

In winter, there is more fog and less sunshine. Due to insufficient ultraviolet radiation and insufficient vitamin D in the human body, some people will experience mental laziness and depression. If necessary, you can add some vitamin D.

(5) Have a light diet and drink plenty of water

The diet in foggy days should choose light and digestible foods rich in vitamins, drink plenty of water and eat more fresh vegetables and fruits, which can not only supplement various vitamins and inorganic salts, but also play a role in moistening the lungs, resolving phlegm, relieving cough, strengthening the spleen and tonifying the kidney. Eat less irritating food and eat more pears, loquats, oranges, oranges and other foods.

(6) It is best not to go out and do morning exercises.

Smog weather is a "health killer" for patients with cardiovascular diseases, especially the elderly with respiratory diseases and cardiovascular diseases. It is best not to go out in foggy days, and it is not suitable for morning exercise, otherwise it may induce diseases and even heart attacks, which may be life-threatening. Experts pointed out that foggy days are "dangerous days" for patients with cardiovascular diseases because foggy days are depressed and the oxygen content in the air drops, so people tend to feel chest tightness and feel wet and cold in the morning.

Fog can also cause cold stimulation, which easily leads to vasospasm, blood pressure fluctuation and increased heart load. At the same time, some pathogens in fog can cause headaches and even induce diseases such as hypertension and cerebral hemorrhage. Therefore, people with cardiovascular diseases, especially the elderly and infirm, should not go out in foggy days, let alone do morning exercises in foggy days to avoid danger.
