The objective of this study was the evaluation of the health risks of the pesticides use and their bioaccumulation by the vegetables grown in Lome gardens. Pesticide residues levels were assessed in vegetable samples collected in Lome areas by Gaz chromatography - mass spectrometry or liquid chromatography - mass spectrometry in order to know their concentrations. Data obtained were used for estimating the potential health risks associated with the exposures to these pesticides.The results showed that all of the samples contain pesticide residues with high levels of Dithiocarbamates (7.79 ppm) in carrots, Chlorpyriphos ethyl (0.445 ppm) in spinach, cucumbers (0.239 ppm), peppers (0.032 ppm), and turnips. Levels above the maximum residue limits (MRLs) of chlorothalonil, and carbendazime were found in peppers, prothioconazole and pendimethalin in turnips, cypermethrin in pepper (0.254 ppm) and in eggplant (0.037 ppm). The pepper has concentrated 5 residues, leek and turnip 4 residues each other, African eggplant 3, lettuce 2 residues and spinach 2 residues. The health risks indices show that the detected pesticides could not be considered as a serious public health problem in the studied conditions, but there is the need to increase their monitoring to reduce their misuse on the vegetables. Keywords : Pesticides residues, vegetables, consumers, health risks indices, Lome-togo.
