| Abstract | ||
| The objective of this research was to monitor the presence of pesticide residues in grapes, oranges, and apples in the Minia Markets. 84 pesticides were investigated. The QuEChERS method was used for the extraction and purification, Residues were analyzed using GCMS/MS and LCMS/MS. The expected daily intake (EOI) and a hazard index were determined. The standard deviations were ( 1% to 7.5%, while the LOD varied from 0.0004 to 0.0231 ng/gm. The LOQ (0.0012 to 0.0693 ng/gm-1.) Furthermore, an R2 value greater than 0.99 was obtained. The results revealed that all samples were contaminated with residues of 35 different pesticides, out of which 31.48% exceeded the maximum residual limits (MRLs), while 64.8% contained concentrations below the MRLs. The most frequently detected pesticides were cypermethrin (found in 27 out of 54 samples), followed by carbendazim (20/54), profenofos (10/54), orthophenylphenol (OPP) (9/54), and Pascalid (9/54). Chloropyrifos, thiabendazole, and myclobutanil were detected in 6 out of 54 samples. On the other hand, lambda-cyhalothrin, thiophanate methylchlorobrofam, methoxybenzene, thiamethoxam, clothianidin, methoxyphenoside, hexethizox, malathion, and maloxone were the least frequently observed pesticides in the collected fruit samples. | ||
