 In this study , mass size distributions of ambient aerosol particles and their water - soluble organic and inorganic species were investigated under high pollution episode . To achieve the aim of this study , 24 - hr integrated size - segregated aerosol samples were collected at an ubran site of Gwangju between November 02 and 16 , 2018 , and analyzed for mass , water - soluble organic carbon ( WSOC ) , and ionic species . During study period , a high pollution episode of fine particulate matter ( PM ) occurred between November 02 and 07 , possibly due to high pressure developed around Korean peninsula , extremely stable air conditions , and long - range transportation of aerosol particles from North Korea and northeastern China region . On November 02 ~ 03 when influence of local pollution dominated , ambient aerosol particles , WSOC , NO 3 -, SO ₄2 -, and NH 4 + exhibited bi - modal size distributions with a condensation mode at a particle size of 0 . 32 μ m and a droplet mode at a particle size of 1 . 0 μ m in PM 1 . 8 . While , between November 05 and 07 when long - range transportation of PM was mixed with locally - produced pollution , they showed very pronounced droplet mode size distributions at 1 . 0 μ m , without a condensation mode . NO 3 - concentration in PM 1 . 8 during pollution episode increased significantly from 5 . 9 μ g / m ³ on November 02 to 21 . 5 μ g / m ³ on November 06 , while SO ₄2 - in PM 1 . 8 increased from 1 . 6 to 5 . 8 μ g / m ³, indicating the dominance of local pollution during pollution episode . Furthermore , for WSOC , NO 3 -, SO ₄2 -, and NH 4 +, fraction of droplet mode size ( PM 0 . 55 - 1 . 8 ) to PM 1 . 8 increased gradually as PM pollution got increased , while the condensation mode ( PM 0 . 17 - 0 . 32 ) contribution decreased . In addition , it was demonstrated that relative humidity could be an important factor promoting formation of droplet mode WSOC , NO 3 -, and SO ₄2 -.
