The method describes the qualitative and quantitative analysis of six polycyclic aromatic hydrocarbons (PAH) in unfiltered water samples such as surface water, rainwater, wastewater and groundwater. Explanation Some PAH are potentially carcinogenic or are suspected of having carcinogenic properties. They appear on the lARC lis [12]. They occur in a dis olved state or adsorbed to solid materials (suspended matter, sediment) in almost all waters. The PAHs lis ed in Table 1 are used as indicators of a much larger group of PAHs that occur in natural waters. The method is aimed at the analysis of these six PAH. The PAH mentioned here do not have to be representative of the PAH that occur in wastewater. The choice of these six PAHs is based on the guidelines of the Council of the European Communities ([1] and [2]). The method is suitable for a PAH content from 5ng/l for each individual component. The detection limit depends on the equipment and the compounds to be determined. The thin layer chromatographic method can be applied for a qualitative and semi-quantitative analysis of the six PAHs (see NEN 6525).
