DUST PREVENTING AGENT AND DUST PREVENTION METHOD
PROBLEM TO BE SOLVED: To provide a dust preventing agent containing no chloride ion, exhibiting effects in short time and hardly being remaining in environment for long time and a dust prevention method using the dust preventing agent.SOLUTION: There is provided a dust preventing agent consisting of nitrate or mainly containing nitrate. There is provided a dust prevention method of soil by applying a calcium nitrate aqueous solution having a calcium nitrate concentration of 10 to 25 wt.% with the application amount per 1 mof the soil of calcium nitrate of 50 to 1,500 g.SELECTED DRAWING: None
【課題】塩化物イオンを含まず、効果が短時間で発現し、長期間、環境に残留することがない発塵防止剤と、この発塵防止剤を用いた発塵防止方法を提供する。【解決手段】硝酸よりなるか又は硝酸を主成分とする発塵防止剤。硝酸カルシウム濃度１０〜２５ｗｔ％の硝酸カルシウム水溶液を、硝酸カルシウムの土壌１ｍ２に対する散布量が５０〜１，５００ｇとなるように散液する土壌の発塵防止方法。【選択図】なし
