This International Standard describes a method for the determination of organic plant treatment agents in drinking and ground water using high performance liquid chromatography (HPLC) with UV detection after
solid-liquid extraction. The method described in this International Standard is applicable to the determination of selected plant
treatment agents and some of their main degradation products (metabolites) in drinking water with a validated reporting limit of about 0,1 ug/l. Limited additional data indicate that it can be extended to 0,05 pg/l. The method may be extended to include additional substances and ground water, provided the method is validated for each individual case. The selection of the plant treatment agents and main degradation products in table 1 has been made according to the knowledge at the time of the interlaboratory trial (1992). Data for some other substances are given in annex A.
Diese ÖNORM beschreibt ein Verfahren zur Bestimmung ausgewählter Pestizide sowie einiger ihrer Haupt-Abbauprodukte und Metaboliten in Trinkwasser in einer Massenkonzentration > 0,05 mg/l. Die Methode kann erweitert werden, um zusätzliche Substanzen und Grundwasser einzuschließen, muss dann jedoch für jeden einzelnen Fall als geeignet erklärt werden.
