摘要
This research work was designed to estimate the gradually increasing use of insecticides on vegetables to create awareness among the consumers regarding their insecticide residues. The main aim of this study is to highlight the harmful effects of insecticides in comparison with dietary intake assessment of vegetables. In this regard, total 180 (n = 60x3) samples of okra (Abelmoschus esculentus) and eggplant (Solanum melongena) comprising of 30 samples vegetable were collected from the peri-urban farming system of Multan, Faisalabad and Gujranwala to assess insecticide residues along with their dietary intake assessment. The selected samples were quantified for the insecticide residues by using High Performance Liquid Chromatography (HPLC) technique equipped with UV/Visible detector. Results revealed that imidacloprid residues found in eggplant (0.226 mg Kg(-1)) and okra (0.176 mg Kg(-1)) from Multan region were greater than the residues reported from Gujranwala and Faisalabad. Out of all analyzed samples for imidacloprid and acetamaprid residues, 58% and 65% samples contained detectable residues respectively. Whereas 10% and 15% samples exceeded their maximum residue limits (MRLs) established by European Commission. Dietary intake assessment for imidacloprid and acetamiprid was calculated as per their maximum permissible intake (MPI) values i.e. 3.84 and 4.48 mg person(-1)day(-1), respectively, which revealed that although a reasonable proportion of samples exceeded MRLs but their consumption was found within safe limit.
