<p>ISO 22959:2009 specifies a high performance liquid chromatographic (HPLC) procedure for the determination of polycyclic aromatic hydrocarbons (PAHs) in edible fats and oils.</p>
<p>The method has been validated for coconut, olive, sunflower, and soybean oil, and is possibly applicable to other oils, dependent on the determination of appropriate parameters.</p>
<p>The lowest level of quantification for the PAHs is 0,1 µg/kg. The lowest possible amount of each PAH which can be distinguished from the baseline noise has not been determined. The validated concentration range of the method is 0,1 µg/kg to 3,5 µg/kg for each individual PAH. For samples containing (light) PAH contents > 3,5 µg/kg, dilution to bring the contents into the validated range is possible. It is also possible to adjust the range of the calibration curves. However, ranges exceeding 3,5 µg/kg have not been validated.</p>
<p>PAHs which can be determined by this method are: anthracene, phenanthrene, fluoranthene, pyrene, chrysene, benzo[<i>a</i>]anthracene, benzo[<i>e</i>]pyrene, benzo[<i>a</i>]pyrene, perylene, benzo[<i>ghi</i>]perylene, anthanthrene, dibenzo[<i>a</i>,<i>h</i>]anthracene, coronene, indeno[1,2,3-<i>cd</i>]pyrene, benzo[<i>a</i>]fluoranthene, benzo[<i>b</i>]fluoranthene, benzo[<i>k</i>]fluoranthene.</p>
