This part of ISO 7981 specifies the determination of six selected PAH in drinking water by high-performance thin-layer 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). A screening method (method A) is described to exclude those samples containing less than 20 % of the limit values given in References [1], [2], [3] and [4]. A quantitative method (method B) is also described, with a working range of 40 ng/l to 240 ng/l (sum of 6 PAH). Higher concentrations can be determined by using a smaller aliquot of the sample. With some modifications, this method is also applicable for the analysis of ground waters and moderately polluted surface waters.
