Abstract
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.
