The degradation of residual insecticide in the vegetables is according to the first order of chemical dynamitic reaction. The half-life of insecticide on/in the vegetable can be calculated through a series sampling and analysis the residual amount to obtain a regression equation or by a simplified equation. Although the total amount of residual insecticide degraded according to the first order of chemical dynamitic reaction, the lost of the partial insecticide which absorbed in the leaves seems likely according to a more complicated exponent curve which has been described. The adsorbed residual insecticide (on the leaves) was easy washed away. The non-ionic detergent is more effect than water. But the absorbed insecticide (in the plant tissue) is hard to wash out.
蔬菜中残留杀虫剂的降解符合化学动力学反应的一级反应。蔬菜上/中的杀虫剂半衰期可通过一系列采样并分析残留量以获得回归方程来计算，也可通过简化方程计算。尽管残留杀虫剂的总量按照化学动力学反应的一级反应进行降解，但叶片中吸收的部分杀虫剂的损失似乎可能符合已描述的更复杂的指数曲线。吸附在叶片上的残留杀虫剂很容易被冲走。非离子洗涤剂比水更有效。但植物组织中吸收的杀虫剂很难洗去。
