To understand the distribution characteristics of PM2.5 concentration in the Saemangeum Reclamation Area and nearby areas, three points of thebackground area, the occurrence area, and the affected area were selected and samples were collected for each season. The chemical composition wasdetermined. As a result of analyzing the chemical composition contained in PM2.5, NO3-(7.2 μg/m3), SO42- (4.3 μg/m3), NH4+ (4.3 μg/m3), OC (2.5μg/m3), Si (1.3 μg/m3) m3) and EC (0.5 μg/m3) seemed to be the main components, and NO3-, SO42-, NH4+, which are components that form secondaryparticles, occupied a large proportion. The composition ratio of PM2.5 was investigated in the order of ion component (56.8%) > Unknown (27.4%)> carbon component (11.8%) > heavy metal component (4.0%). During the PM2.5 high concentration case days, the ionic component accounted for90.7% during atmospheric stagnation cases, whereas the chemical composition ratio was in the order of ionic component (51.7%) > heavy metalcomponent (41.5%) > carbon component (6.8%) during yellow dust cases. It was found that the characteristic of PM2.5 in the Saemangeum reclaimedland and surrounding areas is mainly influenced by outside (domestic and overseas) throughout the year. Ion components accounted for the largestportion of PM2.5 components in this area, but there were few sources of SOx and NOx emission in the Seamangeum area, which are precursors forsecondary particle formation. Therefore, it is judged that most of these are generated and influenced as a secondary reaction in the atmosphere fromthe outside.
Abstract
To understand the distribution characteristics of PM2.5 concentration in the Saemangeum Reclamation Area and nearby areas, three points of thebackground area, the occurrence area, and the affected area were selected and samples were collected for each season. The chemical composition wasdetermined. As a result of analyzing the chemical composition contained in PM2.5, NO3-(7.2 μg/m3), SO42- (4.3 μg/m3), NH4+ (4.3 μg/m3), OC (2.5μg/m3), Si (1.3 μg/m3) m3) and EC (0.5 μg/m3) seemed to be the main components, and NO3-, SO42-, NH4+, which are components that form secondaryparticles, occupied a large proportion. The composition ratio of PM2.5 was investigated in the order of ion component (56.8%) > Unknown (27.4%)> carbon component (11.8%) > heavy metal component (4.0%).
