This Technical Specification specifies a method for the determination by gas chromatography with mass
spectrometric detection (GC-MS) of polycyclic hydrocarbons and pesticide residues in drinking water and ground
water at mass concentrations above 0,005 μg/l and surface water and waste water at mass concentrations
above 0,01 μg/l (for each single compound).
This method can apply to non-polar substances other than polycylic aromatic hydrocarbons (PAH) and pesticide
residues. However, it is necessary to verify the applicability of this method for these compounds.
NOTE 1 A potentially suitable method for this verification is specified in ISO/TS 13530.
This Technical Specification can be used for samples containing up to 150 mg/l of suspended matter.
NOTE 2 Determination of PAH using GC-MS lies within the scope of ISO 28540.
