- Abstract
- BACKGROUND: Recent studies using various industrialwastes for heavy metal stabilization in soil were conductedin order to find out new alternative amendments. The acidmine drainage sludge(AMDS) contains lots of metaloxides(hydroxides) that may be useful for heavy metalstabilization not only waste water treatment but also soilremediation. The aim of this study was to investigate theapplicability of acid mine drainage sludge for heavy metalsstabilization in soilsMETHODS AND RESULTS: Alkali soil contaminatedwith heavy metals was collected from the agricultural soilsaffected by the abandoned mine sites nearby. Threedifferent amounts(1%, 3%, 5%) of AMDS were appliedinto control soil and contaminated soil. For determining thechanges in the extractable heavy metals, CaCl2 andMehlich-3 were applied as chemical assessments for metalstabilization. For biological assessments, lettuce(Lactucasativa L.) and chinese cabbage(Brassica rapa var. glabra)were cultivated and accumulation of heavy metals on eachplant were determined. It was revealed that AMDS reducedheavy metal mobility and bioavailability in soil, whichresulted in the decreases in the accumulation of As, Cd, Cu,Pb, and Zn in each plant.
CONCLUSION: Though the high level of heavy metalconcentrations in AMDS, any considerable increase in theheavy metal availability was not observed with control andcontaminated soil. In conclusion, these results indicatedthat AMDS could be applied to heavy metal contaminatedsoil as an alternative amendments for reducing heavy metalmobility and bioavailability.
