Korea is suffering from fine dust
As soon as I wake up in the morning, I check the weather today and it will be a lot colder today. I'll be hot. I think again how to wear. One more thing to check nowadays. It is to confirm fine dust immediately. I did not think that the world's atmosphere was polluted, I paid the clean air, and the world I was buying was coming. But now in Korea, it is more difficult to find a day out without worrying about fine dust. Dust is limited to seasons, but it always gets worse when the wind blows toward Korea.
As media reports about fine dust, people seem to be a little aware. You may call it a safety insult, but if you still wear a mask, you might hear this sound. "How much longer do you want to live?", "I do not do it if others do not.", "Do not go overboard," "Are you dying to drink some dust?"
Fine dust can be classified by size.
Various epidemiological studies have been carried out on the effects of fine dust on the human body, and it has been found that particulate matter (PM10) of 10 μm or less is highly likely to have harmful effects on the human body, such as increasing disease incidence and mortality in vulnerable populations . Since the results of these studies, governments have begun to prepare air pollution measures, and air pollution standards have been set up to reduce the harmful effects of fine dust on human body and environment.
PM-10 (Particulate Matter Less than 10 μm)
Refers to dust having a particle size of 10 ㎛ or less. It is based on an annual average of 50 ㎍ / ㎥ in environmental standards and 100 ㎍ / ㎥ in 24 hours a year. It penetrates into the alveoli of the human body and becomes a direct cause of various respiratory diseases and deteriorates the immune function of the human body. The World Health Organization (WHO) guidelines set an average annual dose of 20 μg / ㎥ and an average of 50 μg / ㎥ for 24 hours, with an average annual dose of 70 μg / ㎥ for developing countries.
PM-2.5 (Particulate Matter Less than 2.5 μm)
Refers to dust having a particle size of 2.5 ㎛ or less. This is called ultrafine dust. As a result of the fact that the particle size is smaller, the effect on the health is big, and in the developed countries, the criteria for the fine particles started to be introduced in the late 90s.
The Republic of Korea announced the annual average of 25 ㎍ / ㎥, which is scheduled to be implemented in January 2015, and the average of 50 ㎍ / ㎥ for 24 hours. The United States set an annual average of 15 ㎍ / ㎥ and an average of 35 ㎍ / ㎥ for 24 hours. It is called ultrafine dust. The World Health Organization (WHO) guidelines set an annual average of 10 μg / ㎥ and an average of 24 μg / ㎥ for 24 hours.

China, rather than the more domestic issues. Conversely, China is a problem. The cause is divided largely into two.
Air pollutants from fossil fuels such as petroleum and coal, or emissions from automobile soot are known to be the main causes of fine dust.
Korea and China have a tendency to spread toxic fine dust in the season with little or no precipitation because the climate is concentrated 60 ~ 90% of the precipitation only in the summer season. Especially in the winter, it is peaking because of the huge amount of smoke from the heating, but there is little rain or snow.
The influence of China on fine dust is very large. Even if the hypothesis proposed by the pro-Chinese group (Greenpeace et al.) (Adopting 30% of the fine dust from China in Korea) is taken as 100, It is the fare. In fact, when the operation of the old old thermal power plant was stopped in 2017, the fine dust decreased by only 1.1%, indicating that fine dust is not a problem that can be done only in Korea but a diplomatic problem to be solved with China.
Particularly problematic is that the northeast China region close to the Korean peninsula has the highest air pollutant emissions in China. In 2006, NASA, together with China's atmospheric environmental experts, According to the result of the investigation of the material discharge situation, it is revealed that Shandong (Shandong, 1.70 million tons) Hebei (Hebei ㆍ 137.1 thousand tons) Jiangsu (Jiangsu ㆍ 1.2 million tons) Lee Seung-min, a researcher at the KEI, said, "These areas are China's representative densely populated areas, and there are many car movements and industrial parks, which are considered to be serious air pollution areas."
According to the SBS report in January, 2018, Seoul Air Pollution and Dr Lee joonbok (usually) reported that the external influx was 55%, but at high concentration it increased to 72%.

It is a fact that Korea is becoming a super aged society, and it is natural that micro dust should be taken as a material to increase the disease incidence and mortality rate of vulnerable groups. You have to protect yourself. No one will help you. Fine dust will continue to flow in the future. If you have to live with fine dust for a lifetime, not a day or two, then the accumulation is not comparable. You need to watch it with interest.
