Fast and easy multiresidue method employing acetonitrile extraction/partitioning and "dispersive solid-phase extraction" for the determination of pesticide residues in produce.
TLDR
A simple, fast, and inexpensive method for the determination of pesticide residues in fruits and vegetables is introduced and effectively removes many polar matrix components, such as organic acids, certain polar pigments, and sugars, to some extent from the food extracts.

Validation of a fast and easy method for the determination of residues from 229 pesticides in fruits and vegetables using gas and liquid chromatography and mass spectrometric detection.
TLDR
Validation experiments were conducted of a simple, fast, and inexpensive method for the determination of 229 pesticides fortified at 10-100 ng/g in lettuce and orange matrixes, and the results compared favorably with those from traditional methods.

Evaluation of two fast and easy methods for pesticide residue analysis in fatty food matrixes.
TLDR
The recoveries of semi-polar and polar pesticides were typically 100% in both methods (except that basic pesticides, such as thiabendazole and imazalil, were not recovered in the MSPD method), but recovery of nonpolar pesticides decreased as fat content of the sample increased.
