BS ISO 7981-2:2005

This standard BS ISO 7981-2:2005 Water quality. Determination of polycyclic aromatic hydrocarbons (PAH) is classified in these ICS categories:

• 13.060.50 Examination of water for chemical substances

This part of ISO 7981 specifies the determination of six selected PAH in drinking, mineral and table waters and ground and surface waters in mass concentrations above 0,005 µg/l, by high-performance liquid chromatography with fluorescence detection after liquid-liquid extraction. The six PAH are: fluoranthene, benzo[b]fluoranthene, benzo[a]pyrene, benzo[k]fluoranthene, indeno[1,2,3-cd]pyrene, and benzo[ghi]perylene (see Table 1).

With some modification, this method is also applicable for the analysis of moderately polluted waste waters.
