Average annual concentration of fine dust in Busan area

Average annual concentration of fine dust in Busan area

(Busan = Larose.VIP) Reporter Jo Jung-ho = The Busan City Health and Environment Research Institute announced the results of the 2023 air pollution survey on the 20th to protect citizens’ health and improve air quality.

The researcher is monitoring fine dust, ultrafine dust, ozone, sulfur dioxide, carbon monoxide, and nitrogen dioxide through an air quality monitoring network at 32 locations in the city.

As a result of the investigation, ultrafine dust was 16㎍ per ㎥, exceeding the standard (15㎍ or less).

The annual average air environment according to the Enforcement Decree of the Framework Act on Environmental Policy, including ozone 0.0327ppm (0.06 or less in 8 hours), sulfur dioxide 0.0027ppm (0.02 or less in standard), carbon monoxide 0.32 ppm (9 or less in 8 hours), and nitrogen dioxide 0.0141ppm (0.03 or less in standard). The criteria were met.

The concentration trend over the past 10 years showed a decrease in fine dust, sulfur dioxide, carbon monoxide, and nitrogen dioxide, while ozone increased or showed a similar trend.

The Busan City Health and Environment Research Institute said, “The concentration of ultrafine dust was found to be the lowest among the seven major metropolitan cities. This is the result of the city’s continuous efforts to reduce fine dust, such as measures to reduce sulfur emissions from ships and road dust reduction projects.” “I see it,” he said.
