It is stressed that as the number of patients with respiratory diseases increases with the polarization of micro-dust, it is necessary to immediately recognize the risk of fine dust for vulnerable patients and to promote the reduction policy through of international cooperation.
Professor Chung Sung-hwan of the Department of Respiratory Medicine at the Gil Medical Center of the Gachon University School of Medicine presented "The Influence of Fine Dust on the Respiratory System" at the 126th Meeting autumn of the Korean Society of Tuberculosis and Respiratory Disease, which held at the Lotte Hotel World.
Fine dust is clbadified as PM10 fine particles with a diameter of less than 10 μm and PM2.5 fine particles with a diameter of less than 2.5 μm.
About the effects of fine dust on human health ▲ Increased mortality ▲ Increased incidence of malignancies ▲ COPD, chronic respiratory diseases such as worsening of asthma ▲ Children's bone function decreased growth ▲ Respiratory tract inflammation etc.
Recent studies have shown a 0.51% increase in overall mortality from 10 μg / m³ of fine dust.
In particular, the long-term exposure to fine dust increased the incidence of lung cancer, with an increase of 10 μg / m³ PM2.5, the risk of lung cancer increased by 9% .
The 10 μg / m³ increase in PM10 resulted in a 2.7% increase in hospitalizations for chronic obstructive pulmonary disease and a 1.1% increase in mortality.
In addition, pulmonary function tests in children aged 10 to 18 years were the subject of a follow-up study, which showed that the risk of deterioration of lung function in groups exposed to air pollution was multiplied by 4.9.
The harmful effects of fine dust on the human body continue to be revealed, the fear of fine dust grows and the protective measures against fine dust are very small.
In fact, individuals wear masks and the government reacts to fine dust with two vehicles.
Professor Chung Sung-whan said, "It is important to reduce the production of fine dust, but it is not easy." The government advocates measures to prevent fine dust to quickly recognize the risk of dust fine around vulnerable clbades. "We move to damage reduction."
As a result, a real-time air pollution disclosure system is implemented and corrective actions, such as the suggestion of a point of action in the case of fine dust and the withholding of exit according to forecast level predicted for fine dust, are suggested.
Professor Jeong said: "There is a group of vulnerable people who are exposed to micro-dust, and even if they are exposed to fine dust under the same conditions, it is important to take it up," he said. .
In addition, he stressed the importance of choosing the right fine dust to wear a mask, which is almost the only personal measure.
Professor Jung said: "In the case of patients with respiratory and heart diseases and pregnant women, it is possible that this affects health." "It is necessary to wear a mask in consultation with a doctor."
In this way, the way to avoid fine dust is mainly addressed and, at the national level, it is necessary to take measures against fine dust.
Professor Jung said: "Damage to human health caused by fine dust has a wide variety of effects on the respiratory and cardiovascular system, and it is necessary to cooperate with the national emission reduction policy at the same time as international emission reduction policy ".
