  • Curious about Air Quality? Just Look at the Color of N Seoul Tower

    SMG 5419
  • The Seoul Metropolitan Government announced that the average fine dust level throughout spring 2012 in Seoul was 52㎍/㎥, the lowest figure since 1995, when records began, partly because of a reduction in the quantity of yellow dust this spring.

    In fact, the air in Seoul has been getting cleaner by the day in recent years. The city government has arranged for the N Seoul Tower at Namsan (Mt.) to be illuminated in blue if the day’s air quality is 45㎍/㎥ or less (i.e., in terms of fine dust) to enable Seoul citizens to check the air quality quickly and easily. The lighting hours of the tower are from sunset to 11:00 p.m. (10:00 p.m. in winter). The threshold fine dust level of 45㎍/㎥ is about the maximum dust level usually experienced in Jeju, the cleanest island region of Korea.

    N Seoul Tower illuminated in “Sky” Blue

    In the spring of 2012, the N Seoul Tower was lit up in blue for 52 days, showing a four-day increase over 2011.

    The city government attributes the improvement to two major factors: first, there was a reduction in the number of days of yellow dust pollution compared to 2011; second, the efforts of the municipal government and the city’s district offices to reduce the amount of fine dust have paid off.

    With the aim of improving the air quality of Seoul to the level of a few truly clean global cities, the city of Seoul has endeavored to minimize the amount of fine dust in the atmosphere by introducing buses that run on compressed natural gas, enhancing dust control at the city’s various construction sites, and increasing street cleaning with water, as well as implementing measures to reduce the volume of pollution caused by diesel vehicles.
