Pesticide residues in vegetables (watercress mustard green choy sum daikon okra and yam) from Mekong Delta Vietnam were analysed by liquid chromatography-tandem mass spectroscopy (LC-MS/MS). QuEChERS (Quick Easy Cheap Effective Rugged Safe) extraction matrix-matched calibration and dynamic multiple reaction monitoring methods were used. The linear range used was 5 - 200 ng/mL resulting in R 0.99. The recovery was satisfactory with values within 74.47 - 116.93 and the RSD was 15 for most compounds. The percentage of samples with residues above the maximum residue levels (MRLs) was 59. Pesticide residues were detected above their MRLs in samples of watercress (47) mustard green (80) choy sum (83) daikon (87) and yam (60). The results indicated the prevalence of pesticide residues in commonly consumed vegetables in Vietnam and emphasised the urgent need to develop comprehensive intervention measures to reduce the potential health risk to consumers.

Abstract

Pesticide residues in vegetables (watercress mustard green choy sum daikon okra and yam) from Mekong Delta Vietnam were analysed by liquid chromatography-tandem mass spectroscopy (LC-MS/MS). QuEChERS (Quick Easy Cheap Effective Rugged Safe) extraction matrix-matched calibration and dynamic multiple reaction monitoring methods were used. The linear range used was 5 - 200 ng/mL resulting in R 0.99. The recovery was satisfactory with values within 74.47 - 116.93 and the RSD was 15 for most compounds. The percentage of samples with residues above the maximum residue levels (MRLs) was 59. Pesticide residues were detected above their MRLs in samples of watercress (47) mustard green (80) choy sum (83) daikon (87) and yam (60). The results indicated the prevalence of pesticide residues in commonly consumed vegetables in Vietnam and emphasised the urgent need to develop comprehensive intervention measures to reduce the potential health risk to consumers.
