摘    要:通过模拟方法,研究了呋喃丹与土壤中3种重要水解酶类—土壤脲酶、转化酶和碱性磷酸酶的关系及其影响因素.结果表明:呋喃丹加入土壤后,土壤脲酶活性最初受到抑制,随培养时间的延长,呋喃丹的生态毒性逐渐降低,并最终激活脲酶;在0.3%呋喃丹浓度范围内,土壤脲酶、碱性磷酸酶和转化酶均被激活,且部分样品的转化酶活性与呋喃丹浓度呈显著或极显著正相关,说明转化酶活性可在一定程度上表征土壤受呋喃丹污染的程度,且0.3%浓度呋喃丹的生态毒性较弱,对土壤质量及生态环境比较安全.

关 键 词:呋喃丹  土壤脲酶  转化酶  碱性磷酸酶

Abstract:By using simulation method, this paper studied the effects of furadan on the activities of soil urease, invertase and alkaline phosphatase, with the affecting factors investigated. The results showed that after adding furadan into soil, soil urease activity was decreased first but increased then, indicating that the ecotoxicity of furadan was reduced gradually. When the concentration of furadan was less than 0.3%, soil urease, invertase and alkaline phosophatase were all activated, and in some soil samples, a significant positive correlation was observed between soil invertase activity and furadan concentration, suggesting that soil invertase activity could be used as an indicator for the soil pollution caused by furadan. It was concluded that the quality of soil and ecological environment would be kept safe under low concentrations of furadan (< or = 0.3%).
Keywords:furadan  soil urease  invertase  alkaline phosphatase
