ISO 7981-2:20 05规定，通过高效液相色谱法和液-液萃取后的荧光检测，测定饮用水、矿泉水和餐桌水以及地下水和地表水中质量浓度高于0,005微克/升的六种选定多环芳烃。这六种多环芳烃是:荧蒽、苯并[b]荧蒽、苯并[a]芘、苯并[k]荧蒽、茚并[1,2,3-cd]芘和苯并[ghi]苝。 经过一些修改，该方法也适用于中度污染废水的分析。

ISO 7981-2:2005 specifies the determination of six selected PAH in drinking, mineral and table waters and ground and surface waters in mass concentrations above 0,005 micrograms per litre, 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. With some modification, this method is also applicable for the analysis of moderately polluted waste waters.
