Influences of Long-Range Transported Air Pollutants on Atmospheric TSP Aerosol Compositions at Jeju Island of Korea during 2011-2013

摘要

Atmospheric total suspended particulate aerosols were collected at the Gosan site of Jeju Island during 2011-2013, and their major water-soluble ionic and elemental species were analyzed in order to examine the chemical composition change and pollution characteristics change between Asian dust (AD) and non-Asian dust (NAD) periods. The comparison of the aerosol compositions showed that the concentrations of soil-originated species such as nss-Ca2+, Al, Fe, Ti, Mn, Ba, and Sr increased by as much as 4.5-18.6 times during the AD periods. Meanwhile, the concentrations of nss-SO4 (2)
