Aqueous submersion can impede decay and produce decomposition stages not seen in terrestrial burials. To further understand the variances, fifty-four mice were submerged in freshwater, marine water, and a control environment at 20°C. The mice displayed sequential stages at differing rates over 6 weeks. Regression plots and comparative t-tests demonstrated that internal putrefaction, weight difference, and abdominal circumference of the aqueous environments varied significantly from the control group. The aqueous subjects did not vary significantly from each other quantitatively. The postmortem intervals were not consistent regardless of temperature or environment although a clear variance was noted between the control and the submerged groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
