폐지와 폐목재에서의 잔류성 유기오염물질의 농도 및 배출원 추정

We investigated the concentration and the sources of ubiquitous persistent organic pollutants [i.e., 17 toxic polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), 12 coplanar polychlorinated biphenyls (Co-PCBs), and 16 priority polycyclic aromatic hydrocarbons (PAHs)] in waste papers and l...

Description
Summary:We investigated the concentration and the sources of ubiquitous persistent organic pollutants [i.e., 17 toxic polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), 12 coplanar polychlorinated biphenyls (Co-PCBs), and 16 priority polycyclic aromatic hydrocarbons (PAHs)] in waste papers and lumbers from industrial complexes. The total concentrations in waste papers and lumbers ranged from 9.69~176.77 pg/g-dry and 0.14~0.25 pg/g-dry for 17 PCDD/Fs, 109.95~4097.25 pg/g-dry and 28.23~59.88 pg/g-dry for 12 Co-PCBs and 9.30~52.18 ng/g-dry and 0.82~1.82 ng/g-dry for 16 PAHs respectively. Generally, the concentration of these pollutants in waste papers was higher than those in waste lumbers. OCDD was dominant in waste papers and lumbers and the PCDD/F patterns of these samples were similar with that of stack gas. The distribution patterns of Co-PCBs in wastes were related with commercial PCB products, indicating the effect of commercial PCB products on ubiquitous environment. The diagnostic ratios of several PAH compounds in waste paper showed that they were related with pyrogenic sources. 본 연구는 산업 현장에서 나오는 폐지, 폐목재에 함유되어 있는 17종 PCDD/Fs, 12종 Co-PCBs, 16종 PAHs 농도 수준과 이들의 발생원 추적을 위해 수행되었다. 농도 수준은 폐지와 폐목재 순으로 PCDD/Fs는 9.69~176.77 pg/g-dry, 0.14~0.25 pg/g-dry, Co-PCBs는 109.95~4097.25 pg/g-dry, 28.23~59.88 pg/g-dry, PAHs는 9.30~52.18 ng/g-dry, 0.82~1.82 ng/g-dry로 조사되었으며, 모든 대상물질은 폐목재보다 폐지에서 더 높은 농도로 검출되었다. PCDD/Fs 중 OCDD가 가장 높은 농도로 검출되었으며, 소각로 배출가스 중 다이옥신과 유사한 패턴을 보였다. Co-PCBs 이성질체 분포 패턴은 상용 PCB 제품의 이성질체 분포패턴과 유사하게 나타나 이로 인한 오염으로 판단되었고, PAHs의 경우 특정 화합물의 농도비를 이용하여 추정한 결과 폐기물 소각과 같은 연소와 관련이 있음을 알 수 있었다.
