Megjegyzések:	The reproducibility of extraction of residues from spiked soil samples and from soils containing incurredresidues was tested with 14C-labeled test compounds of different physical-chemical properties. Nearly100% of the compounds added to the sample before extraction could be recovered with an averagereproducibility relative standard deviation (CV) of 5.4%. The additional steps of the determination process(cleanup, evaporation, etc.) contributed to the major part of the variability of the results (CV D 10-20%).The incurred residues were most efficiently extracted with acetone for 30 min followed by the mixture ofacetone/ethyl acetate 1:1 for additional 30 min. However, they could only be recovered at various extent(64-90% of total residues), underlying the importance of testing the efficiency of extraction. The residueswere identified and quantified by gas chromatography applying thermionic detector. The performanceparameters of the method complied with the international method validation guidelines, and they provedto be robust and suitable for determination of pesticide residues in soils of widely different physical?chemical properties.
