In this paper the efficiency of a method for the separation and identification of pesticides in lanolin is presented. Theses pesticides belong to the organophosphorous and synthetic pyrethroids families. After the gel permeation chromatography, pesticides are separated from lanolin into two fractions corresponding to the two families, which simplify subsequent analysis by gas chromatography.

Key words: Gas Chromatography with Electron Capture Detector (GC-ECD) -- Gel Permeation Chromatography (GPC) - lanolin -- organophosphorous pesticides -- synthetic pyrethroids pesticides.
