本文研究了当地气候条件下甲基敌百虫在桃上的消解动态。甲基异丙磷是一种广泛使用的强效抗胆碱能化合物，在几种植物保护产品中作为活性成分被发现。根据规定的方案进行田间研究。采用多残留分析法测定水果样品中的甲基双硫磷。在改进的Varian 3700仪器上，用NPD检测器，在270 ℃离心下，用气相色谱法进行甲基异硫氰酸根的分析测定。结果表明，太阳辐射和高温是导致其降解的主要原因。两个连续样品之间的残留量差异较大发生在第2和第4天之间。
The article presents assessment of dissipation of methyl parathion on peaches under local climatic conditions. Methyl parathion is a widely used potent anticholinergic compound found as active ingredient in several plant protection products. The field study was done according a defined protocol. For the determination of methyl parathion in the fruit samples, a multi-residue method was applied. The analytical determination of methyl parathion was performed by gas chromatography in a modified Varian 3700 instrument with an NPD detector at 270 degrees centrigrade. The results showed that the main reasons for the degradation are solar radiation and heat. The greater difference of residues between two sequential samples occurred between the 2nd and 4th day.
