Yellow Sand

also known as HwangSa in Korean

Q. What is Yellow Sand/Dust?
Known more commonly as yellow dust by most of the foreign community, it is basically inhalable particles that originate from the dry desert regions of China and Mongolia. There has been yellow dust coming from these regions to Korea for many generations. However, due to the deforestation that has occurred in Mongolia and China, along with the increased industrialization and resulting pollution in China, the yellow dust storms have been occurring with increasing frequency and with greater and greater negative effects.

Q. What does the yellow dust do?
In sufficient concentration, the fine particles can obscure visibility, irritate soft tissues in the eyes, nose, mouth and throat. Because of the high concentration of minerals and other pollutants, it can cause or exacerbate respiratory and cardiovascular problems. Pinkeye is a common side effect in both adults and children. The dust can also damage sensitive equipment, such as computers, etc.

Q. When do yellow dust storms occur?
Although they have general occurred in the Spring (March, April, May), winter yellow sand events have also been reported in Winter in recent years. There were reports of yellow dust in February 20007.
