摘要：通过室内培养和盆栽试验,研究了Se对黄棕壤过氧化氢酶、脱氢酶、脲酶、碱性磷酸酶、转化酶的生态毒理效应.结果表明,土壤Se对脱氢酶、碱性磷酸酶、转化酶有“抗性酶活性”现象.土壤Se对土壤过氧化氢酶和脲酶活性有抑制作用,脲酶受Se的抑制作用最强.土壤Se含量与脲酶抑制率之间具有显著相关性,脲酶抑制率可作为Se生态风险评价的一项生物指示物.
The eco-toxicology effects of selenium (Se) on catalase, dehydrogenase, urease, phosphatase and invertase in brown-yellow soil were studied through room culture and pot culture experiments. Soil Se had “resistive enzyme activity” phenomenon on soil dehydrogenase, phosphatase, invertase. Soil Se had inhibitory action on the activities of soil catalase and urease, with strongest inhibitory action on urease. There was marked correlation between inhibition rate of urease and content of soil Se, so it is feasible to use inhibition rate of urease as a biomarker of Se ecological risk assessment.
