The combination of solid phase extraction and gas chromatography - mas s spectrometry enables fast and reliable analysis of pesticides residues in drin king water. The evaluation of analysis techniques is a priority for laboratories dealing with quality control. The ordinance 89-3 of the 1/3/89 fixes the maximu m acceptable concentrations of micro-pollutants in drinking water including pest icides and chemically related substances belonging to highly diversified chemica l families. This paper described a multiresidue analysis method of triazines, or ganochlorine pesticides and polyaromatic hydrocarbons, adapted from the method E .P.A. 525.2. This multiresidue method and especially the solid phase extraction process employing laminar C18 disks, is evaluated together with relevant statist ical tests as outlined in the NF XP T 90-210 procedure.
Key words: Pesticide analysis -- water analysis -- solid phase extraction -- gas chromatography -- mass spectrometry -- quality control.
