摘要: 提出了一种检测水中叶青双及其降解物2-氨基-5-巯基-1,3,4-噻二唑的反相高效液相色谱分析法,进行了叶青双的水解、光解以及池塘水中自然降解的模拟试验。研究表明:叶青双在水中降解非常快,光解是其降解的主要方式,同时水解也对叶青双的降解有很大贡献。从叶青双的主要降解产物在水中的光解以及叶青双在自然池塘中模拟试验来看,叶青双的降解产物在水中也不稳定。由此得出叶青双在稻区正常使用情况下,不会对水环境及鱼类构成威胁的结论。

Abstract: A reversed phase HPLC method was proposed for measuring fungicide MBAMT and its degradation product 2 Amino 5 Mercaptoe 1,3,4 Thidiazole in water. With this experiments were conducted on hydrolysis and photo degradation of the fungicide and a simulated test on degradation of the fungicide in natural ponds. Studies indicated that MBAMT degraded rapidly in water with photo degradation being its leading factor and hydrolysis being a great contributor, and that the degradation product of MBAMT was unstable in water under natural conditions. Hence, it can be concluded that application of the fungicide of normal dosage in paddy fields would not result in hazard to the aquatic environment and fish. 

Key words: fungicide, hydrolysis, MBAMT, N, N-methylene-bi-(2-amino-5-mercapto-1, 3, 4-thidiazole), photo degradation
