This standard specifies the methods for the analysis and determination of the residues of methadone and methadone in food. Since methadide and methadene will be degraded into methide in the environment or in plants after application, so this standard also specifies the method for determination of methide. This standard applies to sugar beet and soybean samples after one-time spraying of chemical herbicides stabilized and refined stabilized in sugar beet and soybean fields.
