Current status and dietary risk assessment of 11 common pesticide residues in commercial tea in Xi'an City

Abstract

Abstract:

Objective To understand the quality and safety of tea sold in Xi'an City and provide a reference for safe tea drinking among citizens，57 samples of tea were collected from the market，and 11 kinds of common pesticide residues were detected and analyzed，and the risk of pesticide detection in tea was evaluated according to the dietary exposure assessment system. Methods A total of 57 tea samples were collected from February to June 2024. Gas chromatography-mass spectrometry was used to determine the pesticide residues in the samples，and dietary risk assessment was conducted. Results Among the 11 pesticides tested，5 pesticides found in the samples，including chlorantraniliprole，beta-cypermethrin，chlorpyrifos-methyl，methomyl，and flufpyr-methyl，with the detection rates of 40.00%，40.00% and 100.00% for Pu'er tea，jasmine tea，and black tea，respectively，and the detection rates were 80.00% and 77.78% for green and black tea，respectively. The lowest detection rate was 12.50% for green tea. Among the 57 samples，20 samples were not detected any pesticides，and the rest of the samples showed a widespread use of mixed pesticides. Although pesticide residues were detected，the chronic intake risk ranged from 0.000 2 to 0.291 2，all within the acceptable range，indicating no significant impact on human health. Conclusion The detected pesticide residues in the tea sold in Xi'an City were generally at a safe level，but mixed pesticides is common and requires strengthened supervision.
