Environmental conditions and bodily decomposition: Implications for long term management of war fatalities and the identification of the dead during the ongoing Ukrainian conflict

On 24 February 2022, Russia invaded Ukraine in what they referred to as a ‘special military operation’. Since then, both Russia and Ukraine have incurred heavy losses, though there remains great discrepancy between the deaths reported by both nations. In recent joint international interventions following mass casualty incidents, the majority of operations have been situated within countries in the global south; particularly within nations which do not have the appropriate medico-legal surviving infrastructures to provide the relief required in an emergency situation where high levels of deaths have been incurred. Two examples of this are the Asian Tsunami of 2004 and Haitian earthquake of 2010. The Asian Tsunami of 2004 had an epicentre 200 km west of Sumatra, with the resulting Tsunami impacting on coastal areas of Sri Lanka, Maldives, Indonesia, Malaysia, Thailand and India. It is estimated 227,000 deaths. The Haitian Earthquake 2010 of 7.0 magnitude resulted in death toll of 220,00, while the larger magnitude (7.2) earthquake of 2021 resulted in fewer fatalities of 2000. Both mass fatalities of 2004 and 2010 had considerable, multinational responses, which were challenged by scale, extent, and conditions, and resulted in operational protocols being reviewed. In Ukraine, there are robust forensic infrastructures at local and national levels, with well educated, trained and experienced staff. These infrastructures are connected to international structures such as the International Committee of the Red Cross (ICRC) and International Commission on Missing Persons (ICMP). Despite strong facilities and established procedures in Ukraine at the outset of the conflict, the intensity and nature of the fighting within densely populated areas has resulted in considerable civilian and military fatalities, inevitably this has led to temporary burials conducted during or during a lull in fighting. In areas retaken by Ukraine forces there has been considerable local effort to exhume bodies from temporary graves and to identify the remains using primarily DNA. However, the scale of this activity is disproportionate to the scale of the casualties. In this paper, the authors provide an overview of the deaths incurred during the early weeks of the war and will attempt to illustrate the range of variables which will inform the practical response to recover and identify those killed, before they receive their final burial. It will introduce some of the organisations which have provided forensic support and will also identify emerging ethical considerations which should be monitored for the remainder of the conflict

Effects of hydrated lime and quicklime on the decay of buried human remains using pig cadavers as human body analogues

Recent casework in Belgium involving the search for human remains buried with lime, demonstrated the need for more detailed understanding of the effect of different types of lime on cadaver decomposition and its micro-environment. Six pigs (Sus scrofa) were used as body analogues in field experiments. They were buried without lime, with hydrated lime (Ca(OH)(2)) and with quicklime (CaO) in shallow graves in sandy loam soil in Belgium and recovered after 6 months of burial. Observations from these field recoveries informed additional laboratory experiments that were undertaken at the University of Bradford, UK. The combined results of these studies demonstrate that despite conflicting evidence in the literature, hydrated lime and quicklime both delay the decay of the carcass during the first 6 months. This study has implications for the investigation of clandestine burials and for a better understanding of archaeological plaster burials. Knowledge of the effects of lime on decomposition processes also has bearing on practices involving burial of animal carcasses and potentially the management of mass graves and mass disasters by humanitarian organisations and DVI teams.N
