Abstract

The objectives of this study were to select optimal soil amendments through analysis of heavy metal availability in soil and uptake to Miscanthus sinensis Anderss. for phytostablization in heavy metal contaminated soil of abandoned metal mine. M. sinensis was cultivated for 6 months at contaminated soil with several soil treatments (bottom ash 1 and 2%, fly ash 1 and 2%, waste lime+oyster 1 and 2%, acid mine drainage sludge (AMDS) 10 and 20%, compost 3.4%, and control). The analysis results of heavy metal concentrations in the soil by Mehlich-3 mehthod, growth and heavy metal concentrations of M. sinensis showed that AMDS 20% was more effective than other amendments for phytostablization, and AMDS 10% showed second effectiveness. Waste lime+oyster, bottom ash and fly ash were also improved compared to control. Mobility of some heavy metal was increased by treatments. Therefore, it is necessary of preparatory investigation of soil condition to select soil amendment to apply on-site phytostablization.

본 연구는 폐금속광산의 중금속 오염 토양에서 억새를 이용한 식물안정화공법을 적용하기 위해 토양개량제 처리에 따른 토양내 중금속 이동성과 억새내 중금속 축적형태 등을 분석하여 적정 토양개량제를 선발하고자 수행하였다. 이 를 위해 중금속 오염토양을 바닥재 1, 2%, 비산재 1, 2%, 폐석회+굴패각 1, 2%, AMDS 10, 20%, 퇴비 3.4% 등 으로 처리하고, 비교를 위해 아무 처리를 하지 않은 대조구에 억새를 식재한 후 6개월을 재배하였다. Mehlich-3에 의 한 토양내 중금속 함량, 억새 체내 중금속 이동형태 등을 분석한 결과 AMDS 20%가 식물안정화공법에 가장 효과적 인 개량제로 선정되었으며, 2순위는 AMDS 10%가 선정되었다. 폐석회+굴패각, 바닥재와 비산재도 식물안정화공법 적용 효과가 대조구에 비해 개선된 것으로 나타났다. 개량제 처리에 따라 일부 중금속의 토양내 유동성이 증가하는 결과를 보여, 실제 사업 적용을 위해 사전에 대상지역의 토양오염 특성을 분석하여 현장특성에 적합하게 토양개량제 를 선정해야 할 것으로 사료된다.
