农药代谢试验放射性同位素示踪样品处理技术

本文根据相关文件和标准内容,综述了农药登记代谢试验核素选择原则、供试作物要求、示踪剂引入方法以及样品的提取、纯化技术要点。合理的预处理方法可以降低液闪测试的淬灭效应,提高登记代谢试验结果准确性,减少样品和试剂用量,减少放射性废物处理成本和不必要的污染。

Radioisotope Tracer Sample Processing Technology for Pesticide Metabolism Test

According to the contents of "Pesticide Registration Information Requirements" and "Pesticide Metabolism Test Guidelines in Crops", the principles of selection of nuclides for pesticide registration metabolism test, requirements for test crops, tracer introduction methods, and sample extraction and purification techniques are reviewed. The conclusion is that a reasonable pretreatment method can reduce the quenching effect of the liquid scintillation test and improve the accuracy of the registered metabolic test. At the same time, a reasonable pretreatment can reduce the amount of samples and reagents, and reduce the cost of radioactive waste treatment and unnecessary pollution.
