TL;DR: It is indicated that free glyphosate in the soil can be continuously absorbed by, metabolized in, and transported from the roots of the tea tree into edible leaves, and therefore, free glyphosate residues inThe soil should be controlled to produce teas free of glyphosate.

TL;DR: In situ SERS and LC-MS methods were used to detect dimethoate residue on spinach leaves picked on different days after treatment and facilitated a better understanding of the behavior and biological fate of pesticides in a complex biological system.

TL;DR: The results demonstrate that Raman imaging can serve as an in-situ, non-destructive and ultra-rapid technology for determining the tenderness of fresh tea leaves and be used in quality control for tea processing.

TL;DR: Rinsing dried tea leaves before brewing is a traditional way of preparing rolled oolong tea in China and can be used to develop an effective method of rinsing tea before brewing that reduces pesticide exposure risks.

TL;DR: In this article, the levels of glufosinate-ammonium (GLU), glyphosate [N-(phosphonomethyl) glycine; PMG], and its metabolite aminomethemyl phosphoric acid (AMPA) were determined in tea samples by HPLC-MS/MS using several current purification methods and a new method that was developed herein.
