Seoul Mayor Park Won-soo directly rebutted the Chinese government's claim that South Korean major media reported on the 7th that the mayor of Seoul said in a public interview that more than half of the local smog was affected by China and refuted the previous Chinese ecological environment. The position of the spokesperson of the Ministry. But he also admitted that the two countries should work together to study how to deal with smog. On the same day, the Ministry of Ecology and Environment informed the media that the average number of days in Beijing, Tianjin and Hebei and the surrounding areas rose to 50.5% last year, and the PM2.5 concentration fell by 11.8%.
Park Yuan-soo said in a telephone interview on the morning of the reception of the MBC radio program in South Korea, that many studies by the Seoul Research Institute or the research institutes of the Ministry of Environment of the Republic of Korea indicated that 50% to 60% of the fog in Seoul City 霾 is influenced by China. He said that it is meaningless to discuss who is right and who is wrong. South Korea and China and many cities should work together to reduce smog and jointly study countermeasures. Park Won-hyun also said that Seoul City has jointly conducted a number of studies with Beijing to explore how to build a Northeast Asian consortium and work to reduce smog. Liu Youbin, spokesman of the Ministry of Ecology and Environment of China, said at a regular press conference on the 28th of last month that Seoul pollutants mainly come from local emissions and are no wonder China. But at that time, a large number of Korean media expressed their disbelief. Yonhap said on the 7th that Park Yuan-soo's speech on the same day was a direct rebuttal of the Chinese official's statement.
Is Park Yuan-soo's remarks about 50% to 60% of smog coming from China true? Oy my news, a South Korean progressive media, said on the 7th that the cause of smog includes many complicated factors at home and abroad. The report believes that Park Yuan-soo's speech on the day is intended to refute China's claims, but he ignores the basic fact that the causes of smog are complicated. At the beginning of November last year, the National Academy of Environmental Sciences of the Ministry of the Environment of Korea used two air quality observation models developed by the United States to conduct research and analysis on domestic and foreign factors affecting South Korea (China, Mongolia, North Korea, Japan, etc.). The results showed that the smog caused by four days in early November last year, domestic factors accounted for 55% to 82%, foreign factors accounted for 18% to 45%, and foreign factors accounted for more than 50%. In addition, observations from the European Environmental Satellite also showed that nitrogen dioxide was observed in northeastern China and South Korea from November 3 to 6, last year. However, the National Academy of Environmental Sciences of Korea observed that no nitrogen dioxide was introduced into South Korea through the West Sea (ie, the Yellow Sea).
Before, the Korean media has repeatedly accused that South Korea's smog is mainly blaming China. In this regard, Wang Gengchen, a researcher at the Institute of Atmospheric Physics of the Chinese Academy of Sciences, said in an interview with the Global Times on the 7th that from a scientific point of view, the formation of haze is mainly affected by two factors: local emissions and foreign transportation. It is necessary to consider various factors such as local climatic conditions. He said that South Korea itself also has a lot of air pollution sources. Due to the seasonal changes, the transportation of pollutants is mutual. It is better to unite with each other to study how to solve problems.
