What are the effects of fog and haze on human body?

Haze is a combination of fog and haze. Because of the deterioration of air quality, cloudy days have increased and the harm has increased. In many areas of our country, the smog weather phenomenon is combined with fog as an early warning and forecast of disastrous weather. Collectively referred to as "haze weather".

Sulfur dioxide, nitrogen oxides and inhalable particles are the main components of smog, the first two are gaseous pollutants, and the last is

A particulate matter is the chief culprit that aggravates smog weather pollution. They combine with fog and instantly turn the sky gray. The abbreviation of particulate matter is PM, and what Beijing monitors is PM 10, that is, pollutant particulate matter with a diameter less than 10 micron. This particle itself is not only a pollutant, but also a carrier of toxic substances such as heavy metals and polycyclic aromatic hydrocarbons.

Sources of toxic particulate matter in cities: firstly, automobile exhaust. Large vehicles that use diesel are "recidivists" who emit PM 10, including buses, shuttle buses of various units and large transport trucks. Small cars that use gasoline emit gaseous pollutants, such as nitrogen oxides, which are easily converted into secondary particulate pollutants in foggy days, aggravating smog.

Secondly, the waste gas produced by burning coal for heating in winter in the north.

The third is the waste gas emitted by industrial production. For example, industrial kilns and boilers in metallurgy and electromechanical manufacturing industries, as well as a large amount of waste gas generated by the combustion of automobile repair and painting and building materials production kilns.

The fourth is the dust generated by construction sites and road traffic.

Fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the ground, and it is the product of condensation (or sublimation) of water vapor in the air near the ground. The existence of fog will reduce air transparency and worsen visibility. If the horizontal visibility of the target drops below 1000m, 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 mist. When fog is formed, the atmospheric humidity should be saturated (if there are a large number of condensation nuclei, the relative humidity may not reach 100%, and saturation may occur). Because the light scattered by fog composed of liquid water or ice crystals has little to do with wavelength, the fog looks milky white or bluish white.

Haze (mái), also known as haze, can also make the atmosphere turbid by dust, sulfuric acid, nitric acid, organic hydrocarbons and other particles in the air, which will blur the vision and worsen the visibility. If the horizontal visibility is less than 65,438+00,000 meters, the visual field obstacle caused by this aerosol system composed of non-aqueous substances is called haze or dust haze.

The difference between haze and fog

It is because the relative humidity is not large when the smog occurs, but it is saturated in the fog (if there are a lot of condensation nuclei, the relative humidity may not reach 100%, which may lead to saturation). Generally speaking, the visibility deterioration caused by atmospheric haze blurred vision is caused by haze when the relative humidity is less than 80%, while the visibility deterioration caused by atmospheric haze blurred vision is caused by fog when the relative humidity is more than 90%. The visibility deterioration caused by atmospheric haze blurred vision is caused by a mixture of haze and fog when the relative humidity is between 80 and 90%, but its main component is haze. The thickness of haze is relatively thick, which can reach about 1-3 km. Haze is different from fog and clouds, and there is no obvious boundary between haze and clear sky. Smog particles are evenly distributed, and the particle size is relatively small, ranging from 0.00 1 micron to 10 micron, with an average diameter of about 1-2 micron. Floating particles are invisible to the naked eye. Because the smog is composed of dust, sulfuric acid, nitric acid and other particles, the longer the scattering wavelength, the more the light ratio, so the smog looks yellow or orange-gray.

The similarity between fog and haze is sight distance obstacle. However, the reasons and conditions for the formation of fog and haze are quite different. Fog is a large number of tiny water droplets or ice crystals floating in the air, and the formation conditions should have a high water vapor saturation coefficient. When fog appears, the relative humidity of air often reaches 100% or approaches 100%. With the daily change of air humidity, fog is more common or thicker in the morning and evening, and it becomes lighter or even disappears during the day. The effective horizontal visibility is less than 1KM in fog. When the effective horizontal visibility is 1- 10km, it is called light fog.

"There is actually a difference between fog and haze." Sun Leng, a senior engineer in the Climate System Monitoring Office of the National Climate Center, pointed out that fog refers to the weather phenomenon when the visibility is lower than 1 km due to the condensation of suspended water vapor in the atmosphere. The formation of smog is mainly the result of a large number of suspended particles in the air and meteorological conditions. There are three reasons:

-The phenomenon of static wind in the horizontal direction has increased. 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;

-There is an inversion 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.

The increase of suspended particles in the air. With the growth of urban population and industrial development, the number of motor vehicles has soared, and the emissions of pollutants and suspended solids have increased greatly, which directly leads to the decline of visibility.

Danger differentiation

With the deterioration of air quality, cloudy days are increasing and the harm is increasing. In many areas of our country, the smog weather phenomenon is combined with fog as an early warning and forecast of disastrous weather. Collectively referred to as "haze weather". In fact, fog and haze are completely different to some extent. For example, when fog appears, the air is humid; When smog occurs, the air is relatively dry and the relative humidity of the air is usually below 60%. The reason is that a large number of extremely fine dust particles, smoke particles and salt particles float in the air evenly, so that the air with effective horizontal visibility less than 10KM is mixed together. The symbol is "∞". The diurnal variation of haze is generally not obvious. When the air mass changes little and is stable, it lasts for a long time, sometimes exceeding 10 days. Due to weather phenomena such as haze, light fog, sandstorm, sand blowing, floating dust and smoke, the effective horizontal visibility is less than 10KM due to a large number of extremely fine dust particles or smoke particles floating in the air. Sometimes it is difficult for meteorological professionals to tell the difference. It is necessary to comprehensively analyze and judge the weather background, sky conditions, air humidity, color and smell, satellite monitoring and other factors in order to draw a correct conclusion. The weather phenomena of fog and haze can sometimes be converted to each other.

Smog is harmful to the human body after being inhaled into the human respiratory tract, and it can be fatal in serious cases.

Self - protection

1, open the window less in foggy days.

Smoky weather [2] does not advocate opening windows for ventilation in the morning and evening. Better wait until the sun comes out.

Step 2 wear a mask when you go out

You can wear a mask when you go out, which 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, the right amount of vitamin D.

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.

4. 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.

5, easy to cause cardiovascular disease.

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 the "dangerous period" for patients with cardiovascular diseases because foggy days are depressed and the oxygen content in the air drops, which makes people feel chest tightness easily. The wet and cold fog in the morning can also cause cold stimulation, which can easily lead 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. [3]

On June 5th, 20 13, China Association for Science and Technology organized a "face-to-face meeting between scientists and the media" activity, lasg researcher Wang said that the most fundamental reason for such a serious smog was the increase of pollution discharge. The second is the attenuation of atmospheric self-purification ability. After the original pollutants are discharged into the atmosphere, within a certain limit, the atmosphere can dilute and digest the pollutants through its own physical and chemical reactions, so that the air quality can reach the standard. "Beijing is surrounded by mountains on three sides, with 1/3 times a year. Meteorological conditions are very unfavorable to the diffusion of pollutants. In other words, under the meteorological conditions of 1/3, it is very easy for Beijing to form a serious pollution day. "

Ma Xuekuan, chief forecaster of the Central Meteorological Observatory, believes that it is "neither economical nor realistic" to eliminate pollution through artificial rainfall, fog elimination or strong wind. He said that according to the existing scientific and technological level, artificial rainfall can only be carried out in a small local area, with short time and no obvious effect. "Besides, tens of millions of expenses are unbearable."

"Reducing pollution sources and air pollutants is the fundamental way to solve smog." Wang said to him. Li Hong, deputy director of the Beijing Municipal Economic Information Commission, said that according to the emergency plan for Beijing's heavy air pollution day, 58 enterprises in Beijing have stopped production and completely cut off pollution sources; 465,438+0 enterprises have achieved more than 30% pollution reduction by reducing production load and pollution supply and demand; Qianglian Cement and Pinggu Cement No.2 Plant all stopped production, and the cement industry also achieved more than 30% emission reduction tasks.

How to protect skin in foggy days?

Make cream:

[5] Although the ultraviolet rays are weak when traveling, the cream will come in handy because of the smog. When traveling, you must apply the cream, and when you rest at noon, you should wash off the cream before applying it. This can not only reduce the burden on the skin, but also prevent the smog components from being absorbed by the skin.

Do more cleaning:

Because the pores on the skin surface are relatively small skin care windows, smog particles, sulfur dioxide, nitrogen dioxide and other substances are close to the inside of the skin, which will make the back of the skin react to generate different colors of substances, and may also harm the skin from the depths. So be sure to clean more. Here, I remind everyone to do isolation after each cleaning.

Increase resistance:

We can stop the solid particles on the skin surface, but sulfur dioxide and nitrogen dioxide exist in the form of gas, and our skin pores are also part of oxygen supply and breathing, so it is difficult to stop them, but we will find good nutrients for the skin, so that the skin can appropriately increase its resistance, so that whatever is inside the skin can be packed and discharged. So cleaning is very important now.

Replenishing water and resisting haze:

Be sure to replenish water. Only by hydrating the sebum film on the skin surface can we effectively deal with all kinds of harmful environments, so after each cleaning, hydrate the skin first and then isolate it (remember). 44| Comments (25)
