성토재용 폐타이어의 용출특성에 관한 연구

초록

In this study, we tried to determine any detrimental effects on water quality when waste tire obtained from a motor vehicle intended to be used as a fill material in construction sites. Classification of waste tire as a waste material and soil contamination due to the use of waste tire were performed by Korea waste standard leaching test and soil toxicity test, respectively. Results of leaching tests were compared to the criteria for water quality and groundwater quality and no harmful effects on water quality were found. Most heavy metals in leachate were below detection limits but concentration of Cr6+exceeded the criteria. Column leaching tests indicated that concentrations of Zn were slightly higher than the criteria but below regulations within 1 PVE. Therefore, special attention is required for the mobility of Cr6+ and Zn when the waste tire is used as a fill material.
