Abstract:
This research work was done in Punjab forensic science agency in 2013 and it was concluded that regular checking of vegetables should be done to maintain the hygienic level of vegetables. Concentration of six different pesticides Imidacloprid, Chlorpyrifos, Cypermethrin, Lambda cyhalothrin, Carbofuran and Bifenthrin belonging to different classes were determined in fifteen different local vegetable samples by using high performance thin layer chromatography. Diameter comparison was done between standard and sample spot to determine the concentration. Significant difference was detected in presence of pesticides in various vegetables (P<0.05).The highest concentration of pesticides was; Imidacloprid in Okra (0.131 mg/kg), Bifenthrin and Chlorpyrifos in Potato (0.109 mg/kg) and (0.124 mg/kg) respectively, Carbofuranin in Tomato (0.120 mg/kg), Lambda cyhalothrinin in Cucumber (0.114 mg/kg), Cypermethrin in Egg Plant (0.090 mg/kg). It was concluded that cypermethrin and carbofuran possess high rate of contamination of different vegetables samples
