Leaching test of solidified materials in the field indicated that after one week of the start of the experiment the leachate concentrations of Se and Cr meat the Environmental Quality Standards for Soil Contamination. The concentrations of T-N and NO3-N tended to increase with elapsed time, but that of NH4-N decrease. The leachate from the field suggested that cement addition rate should be excess of 15% to meat the Se concentration to the standard. Nitrogen load of this field was greater then that of agricultural field. It would be necessary to increase the cement addition or decrease the permeability of the mixture of solidified material, soil, and cement by compaction in order to reduce the nitrogen load.}, pages = {211--216}, title = {豚ふん素堀池汚泥固化物のフィールド試験に関する研究}, volume = {36}, year = {2007}, yomi = {ドテ, ユタカ and セキト, トモオ} }
