ABSTRACT

According to the 2016 National Air Pollutant Emissions Statistics (CAPSS) released by the Ministry of Environment, Cheongju produced about 4,776.8 tons of fine dust and ultrafine dust in 2016, of which about 2,910 tons (60.9%), Secondary fine dust is about 1,866.4 tons (39.1%). The ratio of secondary fine dust in Cheongju is higher than that of nationwide average of 70:30, which is the ratio of primary fine dust to secondary fine dust. This may be due to the high percentage of pollutants causing secondary fine dust compared to other regions. Among the air pollutants emitted from Cheongju region, sulfur oxides are rapidly decreasing and nitrogen oxides are insignificant but overall tend to decrease, while the amount of volatile organic compounds increases. As a result of the chimney remote monitoring system (TMS), NOX also increases in the waste incineration plant. Estimates of volatile organic compounds have also been shown to be quite high in the processing of waste. Accordingly, the main sources of fine dust in Cheongju are estimated to be road transport pollutants (23.3%), non-road transport pollutants (9.4%), biomass combustion (8.7%), manufacturing combustion (6.3%), and waste treatment (4.9%) to be. The rate of fine dust discharged by waste disposal is more than seven times the national average of 0.67%. In particular, Cheongju seems to have a high proportion of incineration of industrial wastes from outside, and research on the movement of waste incinerators between regions and governmental regulation are essential. It seems necessary to establish a research infrastructure and foster human resources to enable accurate analytical research and policy research in the region.
