Abstract
The purpose of this study is to consider the recycling management of hazardous substances through the confirmation of the concentration characteristics of the unregulated heavy metals total content in construction waste stones generated at new construction sites. The total content of Mn, Ba, Sb, Se, Be and V was analyzed in accordance with the current soil contamination test standards in 25 construction earth waste sample. As a result of the analysis, the Mn concentration of the construction waste earth was (174.24~1109.4) mg/kg and Ba concentration was (29.08~609.05) mg/kg, and these detection values were higher than concentration of domestic natural background soil and reference soil. In addition, the Ba concentration was confirmed as closed or exceeded to concentration of the content regulatory standard of overseas waste(500 mg/kg). It is judged that if the analysis evaluation of the environmental impact that may occurred during recycling process is conducted based on chemical and physical characteristics evaluation, it will contribute to improving the quality and utilization of waste earth.
