Fine dust cause-diesel car to have increased…This year to exceed 10 million

The number of diesel cars that are designated as the main cause of fine dust is increasing in the government`s policy to reduce air pollution emissions. Besides, as China`s superfine dust concentration, which affects the Korean peninsula, is rising, demand for coal heating in China is rising with the strongest wave. Even if countermeasures such as the second division of the public sector are carried out, it is an analysis that it is helpless to infiltrate the Korean Peninsula of super fine dust in China due to the increase of light vehicles and seasonal winds.
According to the Ministry of Land, Infrastructure and Transport on January 18, by the end of 2017, the number of petrols was 10.37 million units, 9.58 million units for gasoline, and 2.1 million units for LPG. As the environmentally friendly LPG car decreased 2.88% Year on Year and gasoline car increased 2.74%, light vehicles increased 4.42%. The growth rate of light trucks decreased from 6.42 percent in the previous year to 406,000 last year. Volkswagen stopped selling in Korea as a `diesel gate`, also resumed sales, so it is expected that the number of registered cars will exceed 10 million by the end of this year.
The share of gasoline in all registered vehicles fell from 49.7% in 2011 to 46.0% last year, down 3.7%, and LPG dropped 3.9% from 13.2% to 9.3%. On the other hand, the share of light vehicles increased from 36.4 percent in 2011 to 42.5 percent last year, up 6.1 percentage points.
The Ministry of Environment plans to increase the fine dust environment standard to the advanced countries such as the US and Japan in the first half of this year. The US ultra fine dust (PM2.5) standard is 35 ㎍ / ㎥ higher than Korea (50 ㎍ / ㎥). However, an industry official said, "The self-employed who are hit by the minimum wage are using a lot of light trucks such as life-style trucks, so the range of policy tricks is narrow," he said.
Meanwhile, some analysts point out that Korea`s environmental diplomacy with China is passive, even though the results of Chinese academics say that China`s pollutants account for an annual average of 44% of the fine dust pollution in the Seoul metropolitan area. Although the Chinese government has changed the heating fuel from coal to natural gas in order to switch to a clean energy source, the supply of natural gas has intensified due to the strongest wave since last December. As a result, China has recently allowed coal to be used for a limited period of time, and the high-concentration fine dust phenomenon is also deteriorating.
"It is clear that the concentration of ultrafine dust in the Korean metropolitan area is rising due to the influence of China, and a study showing that the concentration of ultrafine dust in Korea is significantly increased as seasonal winds in China`s westerly winds "However, after the retaliation of the Chinese sardine, the Korean government has not been able to strongly say to the Chinese environmental authorities` to take proper measures."
Environmental researchers mention that there is a need for modeling of fine-grained international migration and analysis of scientific ultrafine dust infiltration to the extent that China cannot refute it. Specifically, it is argued that atmospheric and environmental engineering studies should be followed to analyze the secondary reaction of air pollutants such as ultrafine dusts from China to Korea, and the migration and diffusion pathways in a one-year time series.
