초록

This study attempted to clarify the characteristics of elemental components and PAHs in the particulate matter (PM) collected at nearby points in incinerator chimney by season. In addition, in order to estimate whether the air quality near the incinerator was affected by the incinerator emission pollutants, the fly ash was also collected in the incinerator chimney.
The elemental concentrations among the three points (Ansim, Samsan, Wansan) differed according to the elements, and there was no significant difference in concentration overall. The seasonal fluctuations of the integrated concentration of hazardous elements show that the concentration of harmful heavy metals was relatively higher in Samsan and Wansan located in the downwind of incinerator than in Ansim, which is the upwind of incinerator. The integrated concentration of the six heavy metals at the sites of this study was similar to that of nearby Samcheon but was significantly lower than those of Daejeon and Seosan. In the case of PAHs concentration of ambient TSP, phenanthrene, fluoranthene, pyrene, and chrysene were relatively high in Ansim and Samsan regions. Meanwhile, in the Wansan region, chrysene, benzo[j+k] fluoranthene, benzo[b] fluoranthene, benzo[a] anthracene were relatively high. The result of enrichment factor for PAHs showed that Samsan, in particular, was found to be affected by incinerator. It was also found that all three regions were more affected by the PAHs originated from incinerators in spring than in winter.
