Parameter detection of pesticide and veterinary drug residues

The scope of gas chromatography-mass spectrometry for the determination of 519 pesticide and related chemical residues in tea This standard specifies the gas chromatography-mass spectrometry method for the determination of 490 pesticide and related chemical residues (see Appendix A and Appendix F) in green tea, black tea, Pu'er tea, and oolong tea, as well as the gas chromatography-mass spectrometry method for the determination of 29 acidic herbicide residues in green tea, black tea, Pu'er tea, and oolong tea. This standard is applicable to the qualitative identification of 490 pesticide and related chemical residues in green tea, black tea, Pu'er tea, and oolong tea. Among them, 453 types of pesticides and related chemicals can be quantitatively determined, as well as dichloro picolinic acid, benzoic acid, p-chlorophenoxyacetic acid, Dicamba, 2-methyl-4-chloro, 2,4-dichloropropionic acid, bromobenzonitrile, 2,4-dichloropropionic acid, 1-naphthylacetic acid, 5-chlorophenol, 2,4,5-dichloropropionic acid in green tea, black tea, Pu'er tea, and oolong tea Determination of residue levels of 29 acidic herbicides, including chloramphenicol, 2-methyl-4-chlorobutyric acid, 2,4,5-thiol, fluconazole, 2,4-dichlorobutyric acid, bentazone, iodobenzonitrile, chlorpyrifos, dichloroquinolinac acid, pyrflufop-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-p-. The method limit for quantitative determination of 453 pesticides and related chemicals in this standard is 0.001 mg/kg to 0.500 mg/kg (see Appendix A). The detection limit for the method of 29 acidic herbicides is 0.01 mg/kg
