Intercomparison Study of Two Multi-Residue Methods for the Enforcement of EU MRLs for Pesticides in Fruit, Vegetables and Grain. Phase IV. Intercomparison Study of Test Materials Containing Incurred Residues

Funded under: FP5-GROWTH

Abstract

Phase IV of this intercomparison was designed to compliment Phase III in assessing the relative extraction efficiencies of three multi-residue methods based on gas chromatography. 'Blank' test materials, which were to be spiked in the laboratory, and test materials which had been prepared from agriculturally treated crops were distributed to participants. The three test materials were tomato, apple and wheat.

The 3 test materials containing incurred residues were tested for homogeneity. Statistical analysis demonstrated that there was no significant (P = 0.05) difference between the inter-and intra- bottle homogeneity for most of the pesticide/test material combinations. Exceptions were, bromopropylate, fenoxycarb and phosalone in apple. However, because the homogeneity analyses were performed on more than one day, this between day variance contributed to and affected the inter-bottle variance. .
