The average annual concentration of super fine dust particles in Busan is the worst among seven major cities in the country according to recent data.
Busan’s average annual exposure to fine-dust was 27µg/m³, which is higher than Seoul and Incheon which both recorded 26µg/m³.
Busan’s air quality is 2.7 times worse than the World Health Organization recommendation of 10µg/m³.
The city has not been able to identify the reason for the high levels and has faced criticism from citizens for not tackling the problem.
Busan currently has 21 tracking stations for fine-dust.
Korea has the second worst fine-dust levels in the OECD, with only Turkey having worse.
