“…A similar range of chemical classes was also identified in the VOC profile of human remains recovered from the Mediterranean Sea, with over 80 VOCs detected using TD-GC-qMS [8]. Following these pioneering studies, other investigations of the VOC profile of human cadavers [9], human remains [5,[10][11][12], select human tissues [13,14] and animal remains [12,15,16], have reported varying numbers of decomposition compounds, ranging from 30 to 135 VOCs. All of these studies were carried out using GCqMS; however, sample collection techniques varied and included sorbent tubes [6-9, 11, 12, 16], diffusive samplers [10], and solid phase microextraction (SPME) [5,[13][14][15], which may account for some of the variation in the number of VOCs reported.…”

following data processing. Future GC-qMS results could be improved by implementing some of these softwareassociated procedures, potentially reducing the magnitude of variation observed between GC-qMS and GC×GC-TOFMS studies. One-dimensional GC analysis may also benefit substantially from coupling with TOFMS detection to provide an indirect increase in peak capacity using deconvolution. However, the wealth of information gained by using GC×GC-TOFMS in decomposition odour profiling is undoubtedly an asset in this field of research.

“…The animals were prepared in a local slaughterhouse in compliance with EU regulations. During euthanasia, efforts were made to reduce blood loss, as blood plasma is considered an additional fluid Table 1 An overview of the main factors affecting the decomposition rate [3,9,10,12,18,24,31,32,35]. The carcasses were placed amongst ruins for simulating the entrapment environment after the collapse of a building.…”

“…During microbiological decay under anaerobic conditions, gases are produced, such as ammonia and hydrogen sulphide, which give the carcass a characteristic putrid odour. The time elapsed since the death and environmental conditions at the site where the body is located have been shown to affect the composition of volatile substances released during the decomposition of mouse carcasses (3,8).…”

Determination of the exact time of death of a human being or animal is extremely important for investigations conducted by law enforcement agencies. The development of a single model of tests and analysis of the site of the incident would be a breakthrough for forensic and veterinary medicine in estimating the exact time of death. Microorganisms play a key role in the putrefaction process. Each stage of decomposition is characterized by the colonization of tissues by different microbial taxa. The objective of the study was to determine the suitability of microbiological tests for establishing the time of death, using the example of the gastrocnemius muscle in a dog (German Shepherd). The results of the study showed that sporulating aerobic bacteria of the species Bacillus cereus, as well as anaerobic bacteria, played a major role in the putrefaction process. No E. coli were found in the material. The first bacterial colonies belonging to the Bacillus cereus group were observed on the 7th day after the death of the animal, and their quantitative growth persisted throughout the study period, i.e. until the 21st day after death. The analysis carried out in this study shows that Bacillus cereus bacteria appear much sooner than anaerobic bacteria.
