Application PAH in Oil
Application Note
Determination of polycyclic aromatic hydrocarbons in oils, fatty
food and free fatty acids by means of GPC-cleanup and GC-MSdetection

Introduction
Polycyclic aromatic hydrocarbons (PAHs) denote a group of substances with several
hundred individual components mainly characterized by a basic structure of at least three
condensed benzene rings as their main characteristic. They are contained in petroleum but
they are also produced when burning organic substances without an adequate supply of
oxygen.
Since some representatives out of this group are carcinogenic, an exact control is therefore
indispensable. Out of the numerous possible compounds, usually only 16 selected PAHs are
analyzed. The valid maximum level for olive marc oil in Spain is currently 2 ppb for heavy
PAHs (incl. benz(a)anthracene) and 5 ppb for their sum.
