However, ignitable liquids in the samples are subject to evaporation as well as microbial degradation. The aim of this work is to investigate accelerators and their changes due to microbial degradation in fire debris. Gasoline changes in different soil types and different time intervals were compared. Based on several authors, mainly alkanes decompose and thus change the chromatogram, from which ignitable liquids are subsequently incorrectly identified. The results indicate the need for rapid and timely analysis of fire debris in laboratories or their storage under specified conditions, therefore freezing to the specified temperature. Keywords: Gas chromatography – mass spectrometry, gasoline, ignitable liquids, microbial degradation, soil 1 Introduction Detection of ignitable liquids is crucial in determining cases of arson. In many cases, an arson uses an ignitable liquid to accelerate a fire. Most ignitable liquids are hydrocarbon-based fuels. Gasoline is the most used ignitable liquid because it is easily accessible, inexpensive, and easily ignited. Gasoline and other ignitable liquids are classified according to the American Society for Testing and Materials (ASTM) guidelines according to their boiling point range and chemical composition. Other common consumer products, which are classified according to chemical composition and boiling point, may also be used. Other product classes include petroleum distillates (e.g., diesel), isoparaffins (e.g., paint thinner), aromatics (e.g., degreasers), naphthenic paraffinic substances (e.g., lamp oil), n-alkanes (e.g., candle oil), de-aromatized distillates (e.g., camping fuel), oxidized solvents (e.g., ketones) and various products such as turpentine. Identification of ignitable liquids is a challenging task that can be affected by several factors. Microbial degradation is one of the three main processes that can change the composition of ignitable liquid residues. Because biodegradation is a time-related aspect, it should be studied at different stages of its development. Although the debate on microbial degradation is relatively new to investigators of the causes of fires, it has long been of interest to environmental researchers and the oil industry. As early as 1946, Claude ZoBell documented that hydrocarbon could be used by microorganisms as their only source of energy (Atlas, 1981; Hybská et al., 2018, Stauffer et al., 2008; ASTM E1618-19; ASTM E1618-06). 7 Delta 2021, 15(1):7−14 The role of the investigator of the causes of the fire in these cases is twofold: to remove the remnants of ignitable liquid from the matrix and to determine the type of ignitable liquid present. While the analysis of volatile compounds in solid matrices is an active area of research, forensic scientists have adopted only a few selected methods for the analysis of fire samples. The use of standardized methods ensures consistency between laboratories and confidence in the results after they are brought to court. Methods
