Determination of Selected Polyaromatic Hydrocarbons by Gas Chromatography-Mass Spectrometry for the Analysis of Wood to Establish the cause of Sinking of an Old Vessel (Scauri wreck) by Fire

The aimof this paper was to establish the cause of sinking of an old wooden vessel by polycyclic aromatic hydrocarbon(PAH) analyses because wood combustion is a source of PAHs. In particular, the molecular PAH patternsgenerated by each source are like fingerprints and it is possible to determine the processes that generate PAHs bystudying their distribution in wood samples. The relative abundance of high molecular weight PAHs, togetherwith the PAH compound ratios and with total index (proposed by us) has demonstrated that samples owetheir PAHs in wood archaeological material to a predominant single mode of origin, i.e. combustion processes,therefore we can say that the sinking of the vessel was caused by a fire.
