| Abstract: | Glyphosate is a commonly used herbicide in tea gardens.In recent years,glyphosate residue in tea has attracted much attention.This article introduced the residue status,detection methods of glyphosate pesticide in tea and its absorption,transport and metabolism behavior in tea plants.The toxicity and risk status of glyphosate metabolite(aminomethylphosphonic acid)were analyzed.In view of the existing problems and potential dangers of glyphosate in tea,corresponding suggestions were put forward to provide early warning for the safety of tea pesticide residues. |
