Water quality. Determination of 16 polycyclic aromatic hydrocarbons (PAH) in water. Method using gas chromatography with mass spectrometric detection (GC-MS)1 Scope This International Standard specifies a method for the determination of at least 16 selected PAH (see Table 1) in drinking water and ground water in mass concentrations above 0,005 g l and in surface water in mass concentrations above 0,01 g l (for each individual compound). This International Standard can be used for samples containing up to 150 mg l of suspended matter. This method is, with some modification, also suitable for the analysis
