title: Chromatographic methods for the determination of pyrethrin and pyrethroid pesticide residues in crops, foods and environmental samples.
abstract: An overview is given of current progress in the analysis of pyrethrin and pyrethroid pesticide residues in crops, foods and environmental matrices. Extraction and clean-up are considered as the sample pretreatment prior to the determination. The conventional procedures (liquid-liquid partition and column chromatography) as well as the newly developed methods (solid-phase extraction, supercritical fluid extraction) are reviewed. GLC, HPLC and TLC chromatographic methods as the final determination of individual pyrethrin and pyrethroid residues and multi-residue, the enantiomer and diastereomer separation as well as the GC-MS confirmation are discussed and summarized in tabular form.
