标准范围

ISO 7981-1:20 05规定了饮用水中六种选定多环芳烃(PAH)的测定。这6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]苝所描述的筛选方法（方法A）排除了那些含有低于20%参考限值的样品。所述定量方法(方法B)的工作范围为40ng/l至240ng/l(6PAH之和)。可以通过使用较小的样品等分试样来测定较高浓度。经过一些修改，该方法也适用于地下水和中度污染地表水的分析。

ISO 7981-1:2005 specifies the determination of six selected polycyclic aromatic hydrocarbons (PAH) in drinking water. The 6 PAH are: fluoranthene, benzo[b]fluoranthene, benzo[a]pyrene, benzo[k]fluoranthene, indeno[1,2,3-cd]pyrene, and benzo[ghi]peryleneThe screening method (method A) described excludes those samples containing less than 20 % of the referenced limit values.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.With some modifications, this method is also applicable for the analysis of ground waters and moderately polluted surface waters.
