Zusammenfassung

Beschrieben werden zwei Arbeitsweisen zur Analyse von Rückständen des Methylcarbamat-Insecticids Carbofuran, die sich gut für routinemäßige Untersuchungen von Tomaten eignen. Die Wiederfin-dungsrate liegt über 90% und die Nachweisgrenze deutlich unter der Höchstmenge des Codex Alimentarius von 0,1 mg/kg.

Summary

Two analytical methods, using GLC/NPD and HPLC to analyse carbofuran residues in tomatoes, are described. Both methods have shown a high recovery rate, up to 90%, and their detection limits are below the maximum residue limit set by Codex Alimentarius Mundi for carbofuran in tomatoes. Therefore, both methods may be of use in routine analysis of this pesticide in those fruits.
