Fine Dust Levels Hit All-Time Low in Seoul

      March 22, 2018 12:19

      The average density of ultrafine or PM2.5 dust particles in Seoul was the lowest in March this year since dust monitoring began in 2014.

      In previous years, fine dust levels would surge to 70 to 80 ㎍/㎥ in March often due to toxic haze from China, but that rarely happened so far this March.

      According to the National Institute of Environmental Research on Wednesday, the average concentration of fine dust in Seoul between March 1 and 20 was 25.6 ㎍/㎥, the lowest in five years.

      Experts said the country has strong easterly winds to thank. They replaced the northwesterly winds that normally carry toxic haze from China.
