South Korea's air pollution is caused by international sources, with some studies suggesting that 60% of it comes from China
South Korea's air pollution is a growing concern for the country and its people. The country's rapid industrialization and economic growth have led to an increase in air pollution, particularly in large cities like Seoul, which is considered one of the world's cities with the worst air quality. South Korea's reliance on fossil fuels, vehicle emissions, and power plants has significantly contributed to the air pollution issue.
While South Korea has taken steps to address the problem, including regulating hazardous air pollutants and planning to close some coal power plants, a significant portion of the country's air pollution is believed to originate from international sources, particularly China. Dust storms from China and Inner Mongolia, as well as emissions from Chinese factories and power plants, are major contributors to South Korea's air pollution. It is estimated that on days with good air quality, 30% to 50% of the PM2.5 pollutant in South Korea comes from China, but on days with poor air quality, this percentage can reach as high as 60% to 80%.
The impact of these international sources of pollution is exacerbated during the colder winter months when air currents are slower and unable to disperse the pollutants drifting across from China. The dust storms, known as Asian Dust Storms, have been linked to various health issues in South Korea, including respiratory and cardiovascular diseases, increased mortality rates, and economic damages amounting to billions of dollars.
While China's rapidly developing economy has led to increased pollution in the region, it is important to note that South Korea also shoulders some responsibility for its domestic sources of pollution, including vehicle emissions, industrial sites, and power plants. The country's heavy reliance on coal-fired power stations and diesel fumes contributes significantly to the overall air pollution levels.
Addressing transboundary air pollution is a complex issue that requires international cooperation and the implementation of stricter emissions regulations. South Korea has expressed concerns about China's lack of restrictions on industrial air pollutants, highlighting the need for collaborative efforts to mitigate the impact of international pollution sources.
