Monitoring of Some Pesticides Residue in Oranges Collected From Tehran´s Market by GC/MS and Evaluation of Safety by Estimation of Daily Intake

In this study, we investigated the presence of 65 pesticides from different chemical groups in 51 different types of orange samples collected from Tehran market in Iran. To determine multiple pesticide residues in orange we used QuEChERS (Quick, Easy, Cheap, Effective, Rugged and safe) sample preparation method followed by concurrent analysis with gas chromatography/mass spectrometry (GC/MS).
