This International Standard specifies a method using high performance liquid chromatography (HPLC) with fluorescence detection after liquid-liquid extraction for the determination of 15 selected PAH (see Table 1) in drinking and ground water in mass concentrations greater than 0,005 µg/l (for each single compound) and surface
waters in mass concentrations above 0,01 µg/l.
This method is, with some modification, also suitable for the analysis of wastewater. This method may be applicable to other PAH, provided the method is validated for each case.
