| Abstract Pesticide residue in vegetables (tomatoes, cucumbers, and potato) from various markets in three areas at Minia Governorate were determined. Using modified (QuEChERS) method vegetable samples are extracted and determination by Gas Chromatography Mass Spectrometry (GCMSMS).The results showed a strong correlation coefficient (≥ 0.992 ) within the detected residues that in a range of 10 to 1000 ng / g-1, along with a recovery rate between 64.4 to 92.16 percent. While, the limit of quantification ranged from 10 to 50 ng / g-1, respectively. After analyzing 54 vegetable samples, the pesticides residues were detected in 66.66 % percent of the samples. The detection limits lies between 0.0019 and 0.028 ng/gm-1. Residues of various pesticides were chlorofenpyer, and chloropyrifos ( with frequency 18/54) followed by imidichlopride, azoxystrobin, (16/54) propagate (15/54), followed with lufenuron (11/54) and dimethemoroph (12/54); carbendazim, thiophinate methyl, metalaxyl, and cyhalothrin ( 9/54) while as difenconzole, omethoate and methomyl were frequented ( 6/54) respecively. The least frequent pesticides were indoxicarb, cymoxanyl, cyfalothrin and acetampride in vegetables from various markets in three different locations at winter 2021 and summer 2022. Chlofenpyer, propargite, chloropyrifos, Carbendazim – lufenoron, and cypermethrin) were found in 44.67% of the vegetable samples hand were more than MRLs., while the other pesticides detected not exceeded the MRLs. Risk ratios were computed and the findings indicate that residues of chlorpyrifos, propagrite, and methomyl from 48 pesticides tested are the most significant commodity contributing to the hazard index (HI) more than 100% and pose a severe public health risk. | ||||
