Multiresidue method for analysis of pesticides in pepper and tomato by gas chromatography with nitrogen–phosphorus detection
TL;DR: In this article, an analytical multiresidue method for the simultaneous determination of various classes of pesticides in vegetables (pepper and tomato) was developed, where vegetables are extracted with acetone and the pesticides are partitioned into ethyl acetate/cyclohexane.

Comparison of octadecylsilica and graphitized carbon black as materials for solid-phase extraction of fungicide and insecticide residues from fruit and vegetables
TL;DR: The data showed that the two extraction methods and both sorbents were able to isolate the pesticide residues from fruit and vegetables, and the best results were obtained using MSPD with C18 which gave recoveries ranging from 70 to 105% and practical detection limits between 5.0 and 50.0 micrograms/kg for all the compounds.
