Abstract

Coal combustion fly ash, which has a high available Si content and alkaline pH, was selected as a potential source of soil amendment in this study. Two field experiments were carried out to evaluate the possibility of heavy metal accumulation in silt loam (Pyeongtaeg series) and loamy sand (Nagdong series) of rice (Oryza sativa) paddy soils to which 0, 40, 80, and $120Mg\;ha^{-1}$ of fly ash were added. Rice yields increased significantly with fly ash application and the highest rice yields were achieved following the addition of around $90Mg\;ha^{-1}$ fly ash. Fly ash increased the soil pH but did not increase heavy metal uptakes of rice and heavy metal concentration in soils, due to very low concentration of heavy metals in the selected fly ash. Labile fraction of heavy metals (exchangeable + acidic fraction) was scarcely contained and most of them were stable and unavailable form (oxidizable and residual fraction). In conclusion fly ash could be a good supplement to an inorganic soil amendments without heavy metal contamination in paddy soils.

우리나라의 석탄회 발생량은 매년 증가되고 있으나 재활용율이 낮아 석탄회의 폐기처리가 심각한 문제가 되고 있어 토양개량제로서 재활용하고자, 석탄회에 포함되어있는 중금속이 벼의 수량 및 중금속 흡수특성과 토양 내 중금속의 이동성에 미치는 영향을 조사하였다. 석탄회의 시용에 따른 토양 내 중금속 총 함량과 0.1 N HCl 가용성 함량의 증가는 발견할 수 없었다. 이러한 결과는 석탄회 자체가 소량의 중금속을 함유하고 있고 토양 내 과량의 석탄회를 시용함으로 인한 토양의 희석효과에서 기인한 것으로 판단되다. 석탄회의 시용에 따라 토양 내 대부분의 중금속 성분은 생물체 흡수가 어려운 유기물 결합태(oxidizable phase)와 광물 내 고정된 중금속 형태(residual phase)로 존재하였다. 석탄회의 시용량 증가에 따른 벼 백미 내 중금속 흡수의 증가는 발견할 수 없었으며 생육기간 동안 생육장애는 나타나지 않았다. 이는 석탄회 시용에 따른 토양의 pH 증대와 유효인산의 증대에서 기인한 것으로 판단되었다. 결론적으로 석탄회 시용으로 인한 토양 및 벼 체내 중금속 축적 현상은 발견할 수 없었으며, 석탄회 시용량 증가에 따라 토양의 pH 개선 및 작물 수량증대에 효과가 있으므로 석탄회는 양질의 토양개량제로서 활용이 가능할 것으로 판단되었다.
