<p>ISO 7981-1:2005 specifies the determination of six selected polycyclic aromatic hydrocarbons (PAH) in drinking water. The 6 PAH are: fluoranthene, benzo[<i>b</i>]fluoranthene, benzo[<i>a</i>]pyrene, benzo[<i>k</i>]fluoranthene, indeno[1,2,3-<i>cd</i>]pyrene, and benzo[<i>ghi</i>]perylene</p>
<p>The screening method (method A) described excludes those samples containing less than 20 % of the referenced limit values.</p>
<p>The quantitative method (method B) described has a working range of 40 ng/l to 240 ng/l (sum of 6 PAH). Higher concentrations may be determined by using a smaller aliquot of the sample.</p>
<p>With some modifications, this method is also applicable for the analysis of ground waters and moderately polluted surface waters.</p>
