Abstract

This study was conducted to find suitable methods for screening organic resources useful for compost. Twenty-seven industrial and domestic sludges were collected from various cities and industrial areas. Contents of organic matters in the sludges were in the range of 79.3-98.0%, and the contents were much higher than the regulation level (60%) for raw materials of compost. Contents of total nitrogen were in the range of 0.8-2.6%. Contents of Fe and Al were very high. Content of HEM was highest in textile sludge ($257mg\;kg^{-1}$) and the contents in the others were in the range of $12.6-90.3mg\;kg^{-1}$. Content of PAHs was lowest in food sludge ($739.1{\mu}g\;kg^{-1}$ and pulp-mill sludge had the highest PAHs content ($3461.8{\mu}g\;kg^{-1}$). $Microtox^{(R)}$ $EC_{50}$ values were higher in the sludges which were classified as a possible material in composting after analysis and investigation. Lettuce root elongation and $EC_{50}$ values were relatively lower in pulp-mill sludge, sewage sludge 3 (Large city), food sludge and leather sludge. Therefore, mineral nutrients, heavy metals, organic compounds (HEM, PAHs, PCBs), and bioassay ($Microtox^{(R)}$ $EC_{50}$, Relative root elongation test) are recommended to be included in the screening system of raw material of compost in addition to the current regulation with organic matter and 8 heavy metals.

본 연구는 퇴비원료로 활용할 수 있는 유기성 자원을 선발할 수 있는 선별체계를 확립하고자 여러 지역 및 산업체를 임의로 선정하여 현재의 규정상 퇴비의 원료로 사용 가능한 물질과 사용 불가능한 물질에 해당되는 유기성 오니를 7종 27점 채취하여 일반성분 함량, 중금속 함량, 유기화합물 함량 등을 조사하였고, 오니 추출물을 이용하여 $Microtox^{(R)}$ 분석 및 상추종자 유근신장에 미치는 영향을 조사하였다. 유기물 함량은 모든 오니에서 79.3-98.0%로 퇴비원료에 규정된 60%를 크게 상회하였고, 전질소 함량은 0.8-2.6% 범위이었다. 철과 알루미늄 함량은 상당히 높았으며, 퇴비원료의 규제기준인 중금속 8종의 경우 아연과 구리함량은 섬유오니에서, 크롬함량은 섬유 및 피혁오니에서, 니켈함량은 섬유, 피혁, 식품, 하수오니 4 (공단지역)에서 그리고 수은함량은 하수오니 3 및 4 (대도시, 공단지역)에서 규제기준치 이상으로 조사되었다. 납, 비소, 카드뮴의 함량은 모든 시료에서 규제 기준치보다 낮았다. HEM 함량은 섬유오니에서 다른 재료보다 월등히 높았으며, PAHs 함량은 제지 오니에서 가장 높았고 그 다음은 피혁오니>하수오니 2 (중소도시)>하수오니 4 (공단지역) 순으로 낮았다. PAHs 함량은 anthracene, phenanthrene, naphthalene, acenaphthene 및 fluorene가 다른 화합물 함량보다 상당히 높았으며, 이들 화합물 함량에서는 제지오니, 피혁오니, 하수오니 2 4 1 (중소도시, 공단지역, 읍 면단위 농어촌지역)에서 다른 오니보다 높았다. $Microtox^{(R)}$ 분석에서 가축분뇨 (돈분뇨), 음식물류 폐기물, 하수오니 1 (읍 면단위 농어촌지역), 식품오니에서 $EC_{50}$ 값이 비교적 높게 나타났으나, 피혁오니, 섬유오니, 하수오니 4 (공단지역)에서 가장 낮은 수치를 보였다. 제지오니, 하수오니 3 (대도시), 식품오니, 피혁오니의 추출물은 상추종자의 유근 신장율을 크게 저해하였다. 따라서 현재 퇴비원료 규제기준인 유기물과 중금속 함량 (8성분) 이외 추가로 일반성분, 미량 중금속, 유해 유기화합물, 생물검정법 및 포장비효시험 등을 이용하여 유망한 유기성 오니의 퇴비원료로 활용 가능성을 검토할 수 있는 방법으로 선별체계를 구축한다면 현재 퇴비원료의 규제기준을 보완할 수 있으며 최종적으로 가장 효과적이고 확실한 검정방법인 작물재배시험을 실시하기 이전에 유용한 유기성 자원의 활용여부를 판별해 낼 수 있으리라 생각된다.
