The claim that the fine dust in China has a huge influence on Korea has become a matter of fact, but will Korean fine dust pass on the wind to China?

In response to this question, Foreign Minister Kang Kyung-hwa emphasized on the Korea-China cooperation regarding air pollution at the National Assembly on February 21, saying, "It is triggered by what happens in our country due to the season.

Experts say that Mr. Kang's remarks are theoretically possible, but in reality they are at a very minimal level.

Park Rok-jin, a professor at Seoul National University's Department of Earth and Environmental Sciences, said, "The influence of a wind blowing in a westerlly wind can be a little influential, but" the impact is very small. "

In the East Sea or the North Pacific, winds of the east wind are blowing on the Korean Peninsula.

In the summer when there is a clean wind in the sea without pollution, the concentration of fine dust in our country is very low.

In the end, even if the atmosphere of the peninsula goes to China with the Dongfeng, the clean atmosphere of the Korean peninsula is shifting in the summer.

Kim Chul-hee, professor at Pusan ​​National University, said, "The effect of Korea on annual average fine dust concentration in Beijing is estimated to be 0.03-0.05%, within 0.1%."

This is similar to the controversy about whether this material will affect Korea when the radioactivity of the Northeast Japan Earthquake and Tsunami Fukushima Nuclear Power Plant leaked in March 2011.

It was the conclusion of the experts at the time that it was possible to do the same on a similar principle, but not to worry.

"It is not that there is a boundary line in the atmosphere, but it can be mixed with the circulation, but because it is a westerly area, Japan (East) Japan (South Korea) It is difficult for South Korea to have a big influence on (the west) China. "

"The concentration of fine dust in China is two to three times higher than that in Korea. Even if the east wind blows, the impact of Korean fine dust on China is minimal," said Zhang Ji-seok, director of the National Institute of Environmental Research.
