폐기물 소각시설 배출가스 중 다환방향족탄화수소류(Polycyclic Aromatic Hydrocarbons)의 배출특성에 관한 연구

Abstract

An exposure to high levels of Polycyclic Aromatic Hydrocarbons (PAHs) compounds are known to be associated with cancer. Especially, Benzo[a]pyrene (BaP) is well known mutagen and carcinogen, which is considered as an Endocrine Disruptor(ED) in view of the environmental toxicology. In present study, the waste incinerator were categorized based an waste characteristic and the air pollution control devices. In order to examine a variation of PAHs concentration and the distribution in emission gas from the municipal, the industrial, the hospital waste incinerator and the sewage sludge incinerator discharged into an environment, 16 PAHs compounds were analyzed from 16 incinerator facilities. The result, shows a wide distribution in range of PAHs concentration. The concentration of PAHs in the emission gas from the waste incinerator ranged between 4.9 to 394.04 ㎍/S㎥. The amount of PAHs released from the waste incinerators were estimated by Top-down approach. The PAHs emission factors of municipal waste, industrial waste, hospital waste were 1,247.5 ㎎/ton, 5,607.3 ㎎/ton, 2,164 ㎎/ton, respectively. In 2012, emission of PAHs from municipal waste, industrial waste and hospital waste are 5.58 ton/year, 19.59 ton/year, 0.31 ton/year, respectively in korea.
