Abstract

In this study, ambient particulate matter pollution was investigated using monthly PM₁₀ concentration data collected from seven major cities in Korea from 1996 to 2010. The highest mean value for the whole study period is seen from the capital city, Seoul (63.2±17.9 μg m^-3), while the lowest is from Ulsan (46.7±14.8 μg m^-3). The concentrations of PM₁₀ in all cities exhibited seasonal variations with the peak values occurring consistently in spring (March or April). The PM₁₀ data in each city consistently exhibited strong correlations (p<0.01) with gaseous pollutants (SO₂, NO₂, and CO), except for O₃ (p>0.05). The analysis of long term trends of PM₁₀ levels indicates a weak but consistent decline in concentrations in most cities with the relative average annual reductions of between 0.4 and 2.8% y^-1.
