global w430×h280 The identification of the specific aromatic compounds, present in the MOAH “cloud”, was outside the scope of the investigation; however, even if desired, the identification of such constituents could not have been performed with satisfactory reliability, because of the low amounts of such constituents. However, it was possible to determine the MOAH quantities (FID trace) and patterns, which are highly important to define the contamination A series of peaks, present in the MOAH fraction, were identified as esterified fatty acids. However, their presence did not affect reliable quantification because these compounds were subtracted from the total MOAH area. The esterified fatty acids derived from t
