The Concept of Fine Dust, Causes of Occurrence, Problems and Solutions of Damage caused by Fine Dust There are many essential factors for human life support, but the most deadly thing would be air. Water and food can be tolerated without eating for several days, but breathing can cause brain damage even if you stop for a few minutes. In addition, harmful substances such as toxic gases can enter the body, leading to death. With industrial development and urban concentration, air quality is deteriorating every year. Not only does this cause health damage to the human body, but it also causes economic damage to all industries. According to a recent survey by the Ministry of Environment, more than 90 percent of the 400 harmful chemicals distributed in Korea are released into the air. In addition, there have been many discussions about the seriousness of air pollution as social problems with fine dust have grown recently. Unlike yellow dust, which usually occurs in spring, fine dust has been affecting our lives all year long. Below, we will look at the concept and the source of fine dust and discuss the current state of damage in Korea and measures to prevent it. 1. The concept of fine dust and the cause of generation 1) Concept of fine dust Before discussing the concept of fine dust, it is necessary to first look at the definition of dust. Dust is a particulate matter that floats or flutters down in the atmosphere, usually generated by burning fossil fuels and automobile exhaust. Depending on the size of the particles, dust is divided into total dust of 50 이하인 or less and fine dust of very small particle sizes. Fine dust is divided into fine dust (PM10) that is smaller than 10 보다 and fine dust (PM2.5) that is smaller than 2.5 보다 (Ministry of Environment, 2016). Because fine dust is so small that it is invisible, it is easy to move through the respiratory tract along the blood vessels into the body. The components that make up fine dust vary depending on the area of occurrence, season, and weather conditions. The ratio of fine dust measured in major regions of the country was the highest at 58.3%, followed by carbon, soot, 16.8% and minerals.
