Abstract

This study was conducted to assessment organic compound and bioassay (density of inhabited animal, fluctuation of predominant fungi, and survival ratio of earthworm) for finding damage on red pepper by heavily amount application of sludges in soil, which was treated with 3 pharmaceutical byproducts and a cosmetic industry wastewater sludge as raw materials of compost, and for establishing estimation method. HEM contents in the soil treated with pharmaceutical byproducts sludge2 (PS2) and cosmetic sludge (CS) were 0.51, 1.10 mg/kg respectively. PAHs content of PS2 treatment in the soil was 3406.8 ug/kg on July 8. In abundance of soil faunas, the pharmaceutical byproducts sludge2 treatment was the most highest. The next was decreased in the order of pig manure (PM) and the cosmetic sludge treatment. However the other pharmaceutical sludge treatments were remarkably reduced populations of soil inhabited animals. In upland soil treated with organic sludges, the numbers of bacteria and fungi of the pharmaceutical sludge treatment were 736, 909 cfu/g and those of the cosmetic sludge treatment were 440, 236 cfu/g, respectively. The pharmaceutical sludge treatments and the cosmetic sludge treatment in identification of predominant bacteria were not any tendency to compare with non fertilizer and pig manure treatments, but they had diverse bacteria than NPK treatment. In microcosm tests, the survival of the tiger earthworm in five soil samples was hardly affected against the soil of PSI (20%) after three months treated in the upland But after six months, survival of PS1 was 80%. At present, raw material of compost was authorized by contents of organic matter, heavy metal (8 elements), and product processing according to 'The specified gist on possible materials of using after analysis and investigation among raw materials of compost', however, for preparing to change regulation of raw material of compost and for considering to possibility of application, this study was conducted to investigate toxic organic compound and bioassay methods using inhabited animal, fungi, and earthworm without current regulation.

본 연구는 퇴비원료로 지정된 제약업종 부산물(공정오니) 및 화장품 제조업 폐수처리오니를 퇴비로서 활용 가능성을 판단하기 위하여 기존의 일반성분이나 중금속 성분 분석 이외 유기성. 화합물과 기타 여러 생물검정법 등을 활용하여 시용한 오니에 의한 토양 내 비료의 피해를 밝혀내고 이들의 평가방법을 확립하고자 포장시험을 수행하였다. 오니의 처리에 따른 HEM의 함량은 제약업종 오니2(PS2)와 화장품 오니(CS)처리가 각각 0.51, 1.10 mg/kg로 가장 높았고, PAHs의 함량은 제약업종 오니2(PS2) 처리에서 $3,406.8\;{\mu}g/kg$로 가장 높았다. 토양에 서식하는 미소동물의 밀도변화는 생육 중기(7월 23일) 및 수확기(10월 1일) 모두 제약오니2 및 돈분 처리구에서 가장 높았으며, 기타 처리구는 차이가 없이 아주 낮았다. 오니의 처리에 따른 세균 및 사상균의 균수는 제약업종오니2처리에서 각각 136, 909 cfu/g로 가장 많았고, 화장품오니도 각각 440, 236 cfu/g으로 다른 처리에 비해 많은 경향을 보였다. 제약오니 및 화장품오니 처리시 우점세균은 무비, 돈분처리에 비해 일정한 경향이 없었으나 3요소 처리보다 다양한 세균이 검출되었다. 오니의 처리에 따른 우점사상균은 무처리에 비해 제약업종 오니2와 화장품 오리처리에서 형태적 특징이 다른 콜로니가 검출되었으나 다른 처리는 비슷한 경향으로 종류간에 큰 차이는 보이지 않았다. Microcosm test를 통하여 오니 처리 후 3개월이 경과한 토양의 오염정도를 평가한 결과는 제약업종 오니3과 화장품 오니처리는 약간 영향을 받아서 $80{\sim}90%$ 생존하였으나, 제약업종 오니1처리는 처리 2주(14일) 이후에는 급격히 생존율이 떨어져서 4주 이후에는 10%만 생존하였다. 그러나 6개월이 경과한 토양에서는 지렁이의 생존율은 제약업종 오니1처리만 약간 영향을 받은 것으로 보였으며 다른 처리들은 전혀 영향을 받지 않았던 것으로 조사되었다. 유기성 오니의 퇴비원료로 활용은 비료관리법의 비료공정규격 중 퇴비의 비고란에 "퇴비의 원료로 사용 가능한 물질과 사용 불가능한 물질"(별표1)에서 "퇴비의 원료 중 사전 분석검토 후 사용 가능한 원료에 대한 지정요령"에는 유기물과 중금속(8성분) 함량(건물중)과 제조공정 등을 검토하여 지정하고 있으나, 지정된 원료가 과연 퇴비원료로 적합한지 잘 알 수 없으며 또한 앞으로 현재의 퇴비원료 규정을 변경할 필요가 있을 경우를 대비하여 퇴비원료의 적합성 여부를 판별할 수 있는 방법의 개발이 필요하다. 따라서 퇴비원료로 이미 지정('02. 12. 31)된 제약오니 및 화장품 오니를 과량으로 토양에 시용한 후 유해 유기화합물, 미소동물, 미생물 및 생물학적(지렁이) 유해성 검정방법의 도입 가능성을 평가하기 거하여 고추를 재배한 포장에서 비료의 피해시험을 실시한 과 유해 유기화합물과 생물학적(지렁이) 유해성 검정방법은 앞으로 연구를 통해서 보완할 경우 상당히 활용 가능성이 있는 좋은 평가방법인 것으로 생각된다.
