What is yellow dust?


Yellow dust is a phenomenon in which fine sand dust is blown high into the sky by strong winds from the dry loess areas of China and Mongolia, mainly in the spring, and floats in the atmosphere and gradually falls. When severe, the sky appears yellow-brown, sunlight becomes cloudy, and dust may accumulate on the ground or objects.


Causes of yellow dust


Yellow dust mainly occurs in the following areas:




  • Gobi Desert and Inner Mongolia Plateau: The main sources of yellow dust affecting our country, often moving directly or via the desert regions of northeastern China.

  • Northeastern China desert region: Yellow dust originating from the Gobi Desert and the Inner Mongolia Plateau sometimes passes through this region and comes to our country, and sometimes originates directly from this region.

  • Loess Plateau: Yellow dust originating in this region often travels through other regions.


When a low pressure area passes through this region, strong winds blow, sending a large amount of yellow dust into the air. This dust is carried by the westerly winds to East Asia, including Korea.


The impact of yellow dust


Yellow dust has various effects on our lives.




  • Health: The biggest problem is the negative impact on health.

    • Respiratory disease: Fine yellow dust particles can penetrate the respiratory tract, including the nose, bronchi, and lungs, causing symptoms such as coughing, sneezing, runny nose, and phlegm, and in severe cases, can worsen bronchitis, pneumonia, and asthma. The elderly, children, and those with respiratory diseases are particularly vulnerable.

    • Eye disease: If yellow dust gets into your eyes, it can cause itching, redness, tears, and a foreign body sensation, and in severe cases, it can cause conjunctivitis and keratitis.

    • Skin conditions: Yellow dust can irritate the skin, causing allergic dermatitis or itching.

    • Cardiovascular disease: Some studies have also reported that increased concentrations of fine dust may increase the risk of developing cardiovascular disease.



  • environment:

    • Crop damage: Yellow dust can cover the leaves of crops, hindering photosynthesis and hindering growth.

    • Livestock damage: Yellow dust can cause respiratory diseases in livestock.

    • Causes acid rain: When pollutants are mixed with yellow dust and fall, it can cause acid rain.

    • Soil Alkalinization: On the other hand, the alkaline components of yellow dust also have a positive aspect in that they neutralize acidified soil.



  • industry:

    • Precision equipment failure: In precision equipment manufacturing facilities such as semiconductor factories, yellow dust can increase product defect rates and cause equipment failure.

    • Flight disruption: Heavy dust storms can obscure visibility and make it difficult for aircraft to take off and land.



  • Daily life:

    • Restrictions on outdoor activities: On days with heavy yellow dust, it is difficult to do outdoor activities and drying laundry is also inconvenient.

    • Causes discomfort: Overcast skies and accumulated dust can cause discomfort.




How to prepare for and prevent yellow dust


It is difficult to prevent the occurrence of yellow dust itself, but efforts to minimize damage are important.




  • Check the yellow dust forecast: It is recommended to regularly check the yellow dust forecast from the Korea Meteorological Administration and refrain from going outside when a yellow dust warning is issued.

  • Wear protective gear when going out: If you must go out, wear a yellow dust mask (KF80 or higher), protective glasses, and long-sleeved clothes to minimize exposure.

  • Personal hygiene: After going out, be sure to wash your hands and feet and brush your teeth.

  • Indoor Environment Management:

    • Close windows and doors to prevent yellow dust from entering the room.

    • Use an indoor air purifier or humidifier to keep the indoor air pleasant.

    • Remove dust by frequently cleaning the interior with a wet cloth or similar.



  • Hydration and nutrition: Drink plenty of water and eat fruits and vegetables rich in vitamin C to protect your respiratory tract mucosa and boost your immunity.

  • Food hygiene management: Wash exposed vegetables, fruits, etc. thoroughly before eating, and practice thorough hand hygiene when preparing food.

  • Creating green spaces in areas where yellow dust occurs: In order to reduce the frequency and intensity of yellow dust occurrence in the long term, efforts to prevent desertification by planting trees in areas where yellow dust originates, such as China and Mongolia, are needed.


Yellow dust is a natural phenomenon, but it has a great impact on our health and lives, so it is important to prepare in advance and respond wisely. If you have any questions, please feel free to ask again!









The reason why yellow dust blowing in from China is particularly dangerous is due to the following complex factors:


1. Possibility of combining with pollutants:




  • China has serious air pollution problems due to rapid industrialization. Yellow dust is likely to mix with harmful pollutants such as smoke, heavy metals, and chemicals as it passes through industrial areas along its route, as well as the areas where it originates.

  • There are also reports that the concentration of heavy metals such as lead, cadmium, nickel, and chromium in modern yellow dust has increased compared to the past. These pollutants can cause more serious health problems to the human body.


2. Accompanied by high concentration of fine dust:




  • Although yellow dust itself is a fine dust particle, yellow dust originating in China often travels together with high concentrations of fine dust.

  • Fine dust particles are so small that they can penetrate deep into the respiratory tract and cause or worsen various respiratory diseases as well as cardiovascular diseases and cerebrovascular diseases.

  • When yellow dust strikes, the concentration of fine dust often reaches 'very bad' levels, posing an even greater threat to health.


3. Seasonal factors:




  • Yellow dust mainly occurs in the spring, when the daily temperature range is large and the weather is dry, making the respiratory mucosa sensitive. In such a situation, exposure to polluted yellow dust can further increase the risk of respiratory disease.


4. Wide-ranging impact:




  • Yellow dust, carried by strong winds, affects not only our country but also a wide area of ​​East Asia, including Japan. Therefore, many people can be exposed to health threats at the same time.


Specific health risks:




  • Worsening of respiratory diseases: It can worsen existing respiratory diseases such as asthma, chronic bronchitis, and emphysema, causing coughing, phlegm, and shortness of breath. In severe cases, it can increase the risk of infectious diseases such as pneumonia.

  • Increased risk of cardiovascular disease: Fine dust can circulate throughout the body through the bloodstream, causing inflammation in the blood vessels and inducing blood clotting, which can increase the risk of cardiovascular diseases such as myocardial infarction and stroke.

  • Causes eye diseases: Yellow dust can enter the eyes and cause conjunctivitis, keratitis, and dry eye.

  • Worsening of skin conditions: May worsen skin conditions such as allergic dermatitis and itching.

  • Causes hair loss: Some studies have shown that fine dust can clog pores in the scalp and cause hair loss.

  • Negative mental health effects: Studies have shown that long-term exposure to high concentrations of fine dust can have negative effects on mental health, including stress and depression.


Therefore, on days when yellow dust from China is forecast, it is important to refrain from going out as much as possible, and if you must go out, wear a yellow dust mask (KF80 or higher), protective glasses, etc., and pay extra attention to personal hygiene.







Here are some ways you can actively deal with yellow dust and contribute to protecting the environment:


1. Reducing the causes of yellow dust (long-term efforts):




  • Support and participate in efforts to combat desertification: Take an interest in and support international efforts to combat desertification in 스포츠토토사이트 and Mongolia, the main sources of yellow dust, and participate in related campaigns or volunteer activities if possible. Activities such as planting trees help prevent soil erosion and reduce dust generation.

  • Practice sustainable consumption: Excessive resource consumption can be an indirect cause of environmental destruction and desertification. Reduce negative impacts on the environment by practicing sustainable consumption such as energy conservation, recycling, and using eco-friendly products.

  • Participate in climate change mitigation efforts: Climate change can worsen droughts and desertification, increasing the frequency and intensity of yellow dust storms. Actively participate in climate change mitigation efforts, such as using public transportation, conserving energy, and using eco-friendly energy.


2. Efforts to minimize damage from yellow dust:




  • Make public transportation a habit: Automobile exhaust fumes are one of the main causes of air pollution, and when combined with yellow dust, they can cause even more serious problems.
