Abstract
This study investigated seven pesticides in vegetables produced in rural South-western Uganda to
determine their suitability for human consumption. Pesticide residue concentrations (ppm) were
determined using QuEChERS method, LC–MS/MS, GC-MS/MS and UV-Vis. Cypermethrin,
dimethoate, metalaxyl, profenofos, malathion, dichlorvos and mancozeb concentrations detected in
sprayed samples ranged between 0.00403 to 0.05350, 0.17478 to 62.60874, 0.12890 to 3.55681,
0.00107 to 0.59722, 0.03144 to 0.63328, 0.00240 to 0.34102 and 0.00001 to 0.00244, respectively.
The residues exceeded MRLs in sprayed samples (59.52 %), unsprayed samples (18 %) and market
samples (8 %). The quality index of the market vegetables was found to be optimal (14.29 %), good
(75 %), adequate (3.57 %) and inadequate (14.29 %). Pesticide residues may lower food quality and
pose risk to human health. Therefore, regulation and monitoring pesticide residues in vegetables
produced in south-western Uganda in order to avoid harmful effects on human health would be
paramount.
