Foods of plant origin - Multiresidue methods for the determination of pesticide residues by GC or LC-MS/MS - Part 1: General considerations

Scope

This European Standard gives general considerations for the determination of pesticide residues in foods of plant origin.
Each method specified in this European Standard is suitable for identifying and quantifying a definite range of those organohalogen, and/or organophosphorus and/or organonitrogen pesticides which occur as residues in foodstuffs of plant origin.
This European Standard contains the following methods that have been subjected to interlaboratory studies and/or are adopted throughout Europe:
- method M: Extraction with acetone and liquid liquid partition with dichloromethane/light petroleum, if necessary clean-up on Florisil® 1) [1], [2], [3];
- method N: Extraction with acetone, liquid liquid partition with dichloromethane or cyclohexane/ethyl acetate and clean-up with gel permeation and silica gel chromatography [4], [5];
- method P: Extraction with ethyl acetate and, if necessary, clean-up with gel permeation chromatography [6].
The applicability of the three methods M, N and P for residue analysis of organohalogen, organophosphorus and organonitrogen pesticides, respectively, is given for each method.
