Atmospheric samples were collected from March to June in 2014. Major ionic constituent (Na+ , NH4+ , K+ , Mg2+ , Ca2+, F- , Cl- , NO3- ,SO42-) , PM2.5 and PMc were observed. Asian Dust storm event were observed from May 28 to June 1 during this sampling period. The concentrations of F-, NO3- , K+, NH4+, Mg2+, Ca2+ in coarse fraction were increased during Asian Dust storm event. The concentrations of SO42- , NH4+, K+ were increased during Asian Dust storm event. The high correlation was recognized between Na+ and Cl- in the coarse fraction. The high correlations were recognized between SO42-, NH4+, K+, Ca2+ and PM2.5.
