Translated title of the contribution: The analysis of thermal decomposition products generated from porcine tissues exposed to outdoor burning conditions

Abstract

Volatile products commonly known as pyrolytic products, are thermal decomposition products generated from the various fuels that are present at a fire scene due to heat exposure. When a fire scene involves human remains, the volatile species generated from the remains can be mistaken with others residues due to the presence of interfering products or ignitable liquid residues from the fire scene. Knowledge of the type of products generated from human remains in real life fire scenarios is crucial under these circumstances. Thus, this study was executed to test the robustness and validity of the pyrolytic data generated from porcine tissue under indoor laboratory burning conditions to those generated under outdoor burning conditions. Porcine bone samples were burnt under outdoor conditions until the ignition of fat occurred (temperatures exceeding 250 °C). The pyrolytic products generated were absorbed onto activated carbon tablets that were incubated in an oven for 16 hours at 80 °C and then desorbed with pentane and injected into the Gas Chromatography-Mass Spectrometry (GC-MS). The 60 pyrolytic profiles obtained were in the range of n-alkanes, n-alkenes, n-aldehydes, aromatics and nitriles, similar to those obtained from the indoor laboratory burning data but with the additional presence of n-aldehydes. Results from this study has indicated that the human pyrolytic data model generated indoors is a good representative of outdoor burning conditions and has also successfully clarified the inconsistencies in terms of the presence and absence of n-aldehydes from porcine and human pyrolytic data.
