정화토양의 토양질 평가

Since the use of the remediated soil is undetermined, the quality of the soil should be appropriately evaluated according to its future use. In this study, we developed a soil quality assessment method that can be applied to soils after the remediation process. Soil quality was assessed based on soils that require productivity for use in agricultural fields and landscaping in uncontaminated, contaminated, and remediated cases using soil washing, landfarming, and thermal desorption. The results showed that the quality of soil washing treated deteriorated the most compared to landfarming and thermal desorption-treated soil, assessed based on the case of use as field soil. In the case of thermal desorption, the range of reduction was smaller than that of soil washing, but soil quality decreased slightly after remediation. However, in the case of landfarming, there was no change in soil quality after remediation. The soil quality indices calculated for landscaping also decreased the most in the soil washing because organic matter and pH decreased during the process. In the case of thermal desorption and landfarming, all the soil quality decreased due to contamination, but it increased slightly after remediation. The two indices applied in this study, SQIT and SQIA, showed similar trends, suggesting that both can be used for soil quality evaluation. Further research is needed on how much the soil quality evaluation results presented in this study can reflect the various services the soil ecosystem provides, that is, the actual soil functions in these soils.
