|
The carbon component of the suspended particulates was analyzed and the DRI model was applied to evaluate the contribution of PCC on visibility and smog phenomena in Seoul area. The results of this study are as follows: It was analyzed that the light absorption in PCC was mainly conducted by EC and the light scattering by OC. Also in the calculation on the contribution of PCC to visibility reduction. the annual average contribution rates of EC and OC were 11.4% and 20.4% respectively and it was confirmed that the visibility reduction was mainly contributed by OC. The annual average contribution rate of TC, the sum of EC and OC, was 31.7%. So it was found out that PCC was the main source for visibility aggravation in Seoul area.
