Hourly measurements of PM2.5 mass, organic and elemental carbon (OC and EC), and water-soluble ionic species were made at the air quality intensive monitoring stations in Baengryeongdo (BR) and Seoul (SL) during the winter (December 01~31, 2013) and summer (July 10~23, 2014) periods, to investigate the increase of PM<SUB>2.5</SUB> and secondary ionic species and the reasons leading to their increase during the two seasons.
During winter, PM<SUB>2.5</SUB> and its major chemical species concentrations were higher at SL than at BR. Contribution of organic mass to PM<SUB>2.5</SUB> was approximately 1.7 times higher at BR than at SL, but the NO₃<SUP>-</SUP> contribution was two times higher at SL. Total concentration of secondary ionic species (SO₄<SUP>2-</SUP>, NO₃<SUP>-</SUP>, and NH₄<SUP>+</SUP>) at BR and SL sites accounted for 29.1 and 40.1% of PM<SUP>2.5</SUP>, respectively. However, during summer, no significant difference in chemical composition of PM<SUP>2.5</SUP> was found between the two sites with the exception of SO₄<SUP>2-</SUP>. Total concentration of the secondary ionic species constituted on average 43.9% of PM<SUP>2.5</SUP> at BR and 53.0% at SL. A noticeable difference in chemical composition between the two sites during summer was attributed to SO₄<SUP>2-</SUP>, with approximately twofold concentration and 10% higher contribution in SL.
Low wind speed and high relative humidity were important factors in secondary formation of water-soluble ionic species during winter at SL, resulting in PM<SUB>2.5</SUB> increase. While the secondary formation during summer was attributed to strong photochemical processes in daytime and high relative humidity in nighttime hours. The increase of PM<SUB>2.5</SUB> and its secondary ionic species during the winter haze pollution period at SL was mainly caused either by long-range transport (LTP) from the eastern Chinese regions, or by local pollution. However, the increased SO₄<SUP>2-</SUP> and NO₃<SUP>-</SUP> during summer at SL were mainly caused by LTP, photochemical processes in daytime hours, and heterogeneous processes in nighttime hours.
