scope:

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.
