These days, fine dust is one of the most serious problems in the world. Fine dust is a microscopic substance that is not visible to our eyes, and is a material that is less than 10 ㎛ in diameter, drifting in the atmosphere for a long 

time.

It is an air pollutant produced when fossil fuels ,such as 

coal and petroleum, are burned. And when many 

manufacturing plants and vehicles make air pollutants 

and they are absorbed into our lungs through the 

respiratory system and causes various lung diseases.

The reason why fine dust makes us worried is that it is very small. The usual dust drifting in the air is 

mostly excreted in the nasal cavity or mucous membrane of the bronchial tubes. However, the fine dust (PM10) is 10 μ m in diameter and is not screened out in oral or bronchial tubes.

Fine dust damages many parts of our body. When fine 

dust accumulates in the bronchial tubes, the germs of the bronchial tubes are easily penetrated and the person with chronic lung disease becomes susceptible to infectious 

diseases like pneumonia. Fine dust also affects the 

development of cancer. According to research, the risk of developing lung cancer increased by 22 % every time 

people inhale the fine dust as much as about 10 μ gm3. 

The possibility of premature death was increased by 7 % each time the concentration of the fine dust was increased by 5 μ gm3. Fine dust can also cause acne 

or pimples and irritate the skin and aggravate atopic dermatitis. Also, if the hair gets covered with snow polluted by fine dust, it can easily destroy the outer layer of the hair. It is recommended to drink water frequently to prevent the disease caused by fine dust. Fine dust is absorbed through the bronchial 

tubes, and when those are moistened, the trace of fine dust cannot enter the body.

Of course, it is best not to go out as long as possible on the day of the fine dust. However, it is recommended to wear long-sleeved clothing and to wear a yellow dust mask to minimize physical exposure if necessary. you had better use an umbrella or a hat when it snows.

In homes or indoors, the windows should be closed because the windows can be the passage of fine 

dust. Using air cleaner to remove particulates of the dust from outside may be helpful. It is recommended to drink more than 8 glasses of water a day because the moisture in the respiratory tract assists the respiratory tract to dry, making it easier to break the dust or yellow dust. Eating fruits and vegetables 

can also prevent yellow dust from having bad effects on the body. When consuming fruits and 

vegetables, sufficiently clean and remove the yellow dust that may be stained on the peel.
