“…Some acid esters/acids were found, depending on the stage of decomposition (Cablk et al, 2012). Blood as a material for VOC analysis is also significant as its odors closely resemble those of human decomposition (Ruffell and Powell, 2021). In a study comparing the volatile profiles of fresh and degraded blood, researchers determined that each generates profoundly different volatile organic compounds, that change over time.…”

The decomposition of a body is inseparably associated with the release of several types of odors. This phenomenon has been used in the training of sniffer dogs for decades. The odor profile associated with decomposition consists of a range of volatile organic compounds (VOCs), chemical composition of which varies over time, temperature, environmental conditions, and the type of microorganisms, and insects colonizing the carcass. Mercaptans are responsible for the bad smell associated with corpses; however, there are no unified recommendations for conducting forensic analysis based on the detectable odor of revealed corpses and previous research on VOCs shows differing results. The aim of this review is to systematize the current knowledge on the type of volatile organic compounds related to the decomposition process, depending on a few variables. This knowledge will improve the methods of VOCs detection and analysis to be used in modern forensic diagnostics and improve the methods of training dogs for forensic applications.

Geoscientists are being increasingly asked by law enforcement, environmental agencies and even wildlife trusts to investigate suspected illegal activities in and around water bodies for criminal or civil investigations. Searches and surveys in aquatic environments can be challenging, depending on the item(s) of interest that is being looked for, the available search teams and equipment and the search area. This article will briefly detail the current work of geoscientists in assisting these aquatic investigations, provide some relevant case studies and discuss future developments.
