ABSTRACT Tea is one of the most popular beverages in world. In tea plant ( Camellia sinensis ) cultivation, application pesticides and herbicides constitutes a common agricultural practice for integrated pest management weed control. Researchers usually focus on pesticide residues itself rarely study soup. This presents rapid quantitative analysis method detecting 36 green The involves using effervescent‐assisted extraction combined with dispersive liquid–liquid microextraction. Pesticides soup are extracted nonanoic acid, during process, sodium carbonate solution (Na 2 CO 3 solution) sulfuric acid (H SO 4 added to produce carbon dioxide auxiliary extraction. solidified substances then dissolved methanol analyzed LC–MS/MS. revealed that target exhibited strong linear responses across concentration range 1–50 ng mL −1 , correlation coefficients R exceeding 0.99. developed demonstrated limit quantification (LOQ) 0.1 µg L accompanied by recovery rates ranging from 76.3% 101.4% relative standard deviations (RSDs) below 6.7% all validation parameters. approach cost‐effective, minimizes use organic reagents, reduces environmental pollution. Overall, combination microextraction efficient soup, making it suitable routine commonly used
