Abstract

At the end of November 2010, livestock infected with foot and mouth disease (FMD) were buried, increasing concern about secondary pollution of drinking water and groundwater with odor. Hence, measures to reduce pollution of drinking water and groundwater are needed. In this study, based on livestock type and soil texture, five pilot-scale burial sites were monitored for the past three years from Feb 2012 to 2015. Leachate from the site was analyzed for 90 compounds. A detailed investigation has been completed, looking into organic matter decomposition characteristics of the buried bodies, relevant trace elements thereof, and in particular metabolite concentration changes such as the degree of decomposition of a carcass. From the results, no detectable heavy metals, including cadmium and arsenic, were measured. Among animal types, the rate of cattle decomposition is faster than swine decomposition, and the decomposition of the bodies were performed in sequence from sand, clay loam, sandy loam.

2010년 11월말 5번째 구제역이 발생하여 가축 매몰지로 인한 악취물질, 지하수, 음용수 등에 2차 환경오염 발생 가능성에 대한 문제제기 등 환경영향 저감 방안 마련이 필요하다. 본 연구의 목적은 축종별, 토성별 파일럿 규모 가축매몰지 5기를 설치하여 2012년 2월부터 2015년 2월까지 약 3년 동안 침출수를 채취하여 90 항목을 분석하였으며, 매몰사체의 유기물 분해특성, 사체관련 미량원소 특히 대사체 물질 농도변화, 사체분해정도 등을 정밀 조사하였다. 그 결과 비소, 카드뮴 등 대부분의 중금속은 검출되지 않았으며 토성에 따른 축종별 분해정도를 파악한 결과 돼지보다는 소가 더 빨리 분해되고 사질 > 식양질 > 사양질 토양 순으로 사체분해가 이루어지는 것으로 판단된다.
