摘要
Analysis of volatile hydrocarbons in blood from fire-related deaths provides useful information such as whether the victim inhaled smoke from the fire before death or whether an accelerant was used in the fire. In this study, we used headspace gas chromatography-mass spectrometry to quantify volatile hydrocarbons in post-mortem heart blood from 121 fire victims. The cases were classified into the following four groups according to the detected volatile hydrocarbons: construction fires without accelerants, kerosene fires, gasoline fires, and a group with no fire-related hydrocarbons detected (other fires). We investigated the relationships between blood concentrations of carboxyhemoglobin (COHb) and volatile hydrocarbons, and between various volatile hydrocarbons. The mean COHb concentrations were higher in the construction fire group than in the kerosene and gasoline fire groups. In the construction fire group, there was a high correlation coefficient between the concentrations of benzene and COHb and relatively high coefficient correlations between the concentrations of benzene and toluene, benzene and xylene, toluene and styrene, and ethylbenzene and styrene. Our results indicate that the relationships between benzene, xylene, and toluene concentrations could be used to distinguish between deaths in construction fires, kerosene fires, and gasoline fires.
