Online published on 1 November, 2023. Abstract Background Many studies have reported the contamination by pesticides in a variety of matrices, such as food, water and soil, which despite their use, health risk of pesticides residues on food and in drinking water for the general population has been raised. The aim of this study is to quantify the pesticides residues of Abamectin and Imidacloprid in some vegetable samples; to study the in vitro effects of the both pesticides on the lipid peroxidation and hemolytic activity and finally, based on the mathematical models we estimate the values equivalent to the concentrations of pesticide residues detected in the vegetable samples. Methods The extraction of pesticide residues from vegetable samples we use the FaPEx kits. Agilent Technologies 1260 infinity high performance liquid chromatography having UV/visible detector was used for the identification and quantification of pesticides residues. The results of this study proved the presence of pesticide residues in vegetable tested with higher values comparing with their corresponding MRLs. Result The mean of the quantity of Abamectin detected in the vegetables samples ranged from 1.93 to 4.11 mg/kg for the green pepper (Capsicum annuum spp) and courgette (Cucurbita pepo), respectively. In addition, the Imidacloprid is just detected in the cucumber (Cucumis sativus) samples and the mean value of quantity is 24.09 mg/kg and corresponding MRL is 0.05 mg/kg. The in vitro study of the effects of the both pesticides on lipid peroxidation and hemolytic activity demonstrate significant effects of the different concentrations of the both pesticides on the both activities. The estimation by mathematical models of malondialdehyde quantity and hemolytic activity equivalent to the concentrations of the pesticides residues detected in vegetables samples proved the non-toxicity effects of these residues.
