Despite the drop in Beijing’s pollution levels, it is still far worse than Seoul’s:

Ultrafine dust in the capitals of Korea and China are composed of similar elements, though some of the elements’ ratios differ greatly, a joint research team of Korean and Chinese researchers announced Wednesday.

The Chinese government’s restrictions on fossil fuel emissions seem to be causing the difference, as Beijing’s air quality improves – and Seoul’s does not. 

At this point, however, further analysis is needed to pin down the exact reasons why. 

Korea’s joint research with China was the latest effort by the two neighboring countries to battle ultrafine dust, which Korea often blames China for, even as the latter adamantly denies responsibility for Korea’s air pollution.

Jeon Kwon-ho, a researcher from the National Institute of Environmental Research (NIER) in Incheon, said the fundamental purpose of the recent research was to find out the sources of ultrafine dust in Seoul and Beijing. 

So far, the research team can say that the pollutants causing ultrafine dust seem to be derived from industrial plants and vehicle exhaust emissions.
