Scope

This standard specifies the determination of residues of 14 pesticides and their metabolites in tea and its products and substitute teas by liquid chromatography-mass spectrometry. It is applicable to the determination of residues of toxaphene, pentachlorophenol, permethrin, phorate, phosmet, heptamaloxyl, metsulfuron-methyl, chloridazon, sethoxydim, amitrole, tolylfluanid, indoxacarb, neem oil, and fenbutatin oxide in fresh tea leaves, tea, tea-containing products, and substitute teas. Other matrices can be referenced for implementation. The quantitative limit of the standard is 0.01mg/kg. The standard stipulates the requirements for reagents, consumables, equipment, and data processing, as well as the main technical contents such as sample pretreatment processes and instrument analysis conditions, ensuring the scientificity, standardization, and operability of the method.
