Abstract

Following on from the earlier work of the Zweckverband Landeswasserversorgung (Regional Water Supply Association), a multi-method system for determination of pesticides based on solid phase extraction/HPLC (high pressure liquid chromatography) was developed and refined. This method makes possible the simultaneous proof of absence of almost 200 pesticides and metabolites, without derivatisation and with only 2 courses of analysis, in a practicable form which is well-suited to routine analytical procedures. At the same time any pesticides and metabolites present can also be identified and quantitatively detected in concentrations 0.1 {mu}g/l. Using the results of the investigations which were carried out in order to optimise solid phase extraction whilst taking into consideration the extraction ph value, it is now possible to calculate the amount of C18 material required for quantitative extraction of a substance. For optimum detection of extractable substances, extractions both at pH = 7 and 2.0 are necessary, although in some cases a single extraction at ph = 2.8 can also be employed. 224 substances were included in the investigations, of which 189 proved to be detectable by means of the multi-method procedure. Thus, in combination with the GC (gas chromatography) or the GC/MS (gas chromatography mass spectrometer), this procedure  More>>

Thus, in combination with the GC (gas chromatography) or the GC/MS (gas chromatography mass spectrometer), this procedure allows a significant simplification of the detection of substances listed under no 13, Appendix 2, of the Drinking Water Regulations (Trinkwasserverordnung). (orig.) With 14 refs., 19 tabs., 20 figs. [Deutsch] Ausgehend von Vorarbeiten des Zweckverbandes Landeswasserversorgung wurde auf der Basis der Festphasenextraktion/HPLC eine Multimethode entwickelt, mit der im Routineanalysenbetrieb ohne Derivatisierung mit nur 2 Analysenlaeufen der simultane Nachweis der Abwesenheit von fast 200 Pflanzenbehandlungs- und Schaedlingsbekaempfungsmitteln (PBSM) und entsprechender Metabolite erbracht werden kann. Gleichzeitig koennen vorhandene PBSM und -Metabolite auch in Konzentrationen {<=} 0.1 {mu}g/l identifiziert und quantitativ nachgewiesen werden. Anhand der Ergebnisse der zur Optimierung der Festphasenextraktion unter Beruecksichtigung des Extraktions-pH-Wertes durchgefuehrten Untersuchungen ist es nunmehr moeglich, die fuer eine quantitative Extraktion eines Stoffes benoetigte Menge an C 18-Material zu berechnen. Fuer die optimale Erfassung der extrahierbaren Stoffe sind je eine Extraktion bei pH = 7 und 2.0 erforderlich. Fallweise kann jedoch auch mit einer einzigen Extraktion bei pH = 2.8 gearbeitet werden. In die Untersuchungen wurden 224 PBSM und -Metabolite einbezogen; davon erwiesen sich 189 als mit der Multimethode nachweisbar. Diese ermoeglicht somit in Kombination mit der GC bzw. GC/MS eine deutliche Vereinfachung des Nachweises der unter Nr. 13 Anlage 2 der TrinkwV aufgefuehrten Stoffe. (orig.) With 14 refs., 19 tabs., 20 figs.}
