Some death scene investigations commence without knowledge of the location of the body and/or decomposition site. In these cases, it is necessary to locate the remains or the site where the body decomposed prior to movement. We hypothesized that the burial of a mammalian cadaver will result in the release of ninhydrin reactive nitrogen (NRN) into associated soil and that this reaction might have potential as a tool for the identification of clandestine graves. Juvenile rat (Rattus rattus) cadavers were buried in three contrasting soil types in Australian tropical savanna ecosystems and allowed to decompose over a period of 28 days. Soils were sequentially harvested and analyzed for NRN. Cadaver burial resulted in an approximate doubling (mean = 1.7 +/- 0.1) in the concentration of soil NRN. This reaction has great potential to be used as a presumptive test for gravesoil and this use might be greatly enhanced following more detailed research.
一些死亡现场调查在不知道尸体位置和/或尸体分解地点的情况下就开始了。在这些情况下,有必要在移动尸体之前找到遗体或尸体分解的地点。我们推测,哺乳动物尸体的埋葬会导致茚三酮反应性氮(NRN)释放到相关土壤中,并且这种反应可能有潜力作为识别秘密坟墓的一种工具。幼年大鼠(褐家鼠)尸体被埋在澳大利亚热带稀树草原生态系统的三种不同土壤类型中,并放置28天使其分解。土壤被依次采集并分析NRN。尸体埋葬导致土壤NRN浓度大约翻倍(平均值 = 1.7 +/- 0.1)。这种反应很有潜力用作墓土的初步检测,并且在进行更详细的研究后,其用途可能会大大增强。
