About Book: This book present the work that the study of investigate pesticide residues in market fruit and vegetables. Pesticide residues were determined by Gas Chromatography- Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry. A Multi-residue and PGR methods were described for simultaneous determination of pesticides commonly used in crop protection. This methods used to determine pesticide residues with a broad range of physicochemical properties in fresh fruits and vegetables related to Organophosphorus (OPP), Organochlorines (OCP), Pyrethroids, and Carbamates mainly used in agriculture. Sample extract was cleaned up by using SOP. Pesticide residues above the Maximum Residue Limits (MRLs) were detected in some of the samples, but most of sample has no residues or contained pesticide residues at or below MRLs. The detected and most frequently found pesticide residues were 4-bromo-2-chlorophenol, Abamectin, Buprofezin, Hexaconazole and Acepahate.
