In homicide investigations, it is critically important that post-mortem (PMI) and post-burial interval (PBI) of buried victims are determined accurately. However, clandestine graves can be difficult to locate; and the detection rates for a variety of search methods can be very low. This paper presents elemental analysis results of 18 months of decomposition fluids from an in situ buried animal cadaver used as a human clandestine burial proxy. Study results showed potassium, sulphate and sodium are key detectable elements which mirror observed conductivity temporal changes from this and other studies. Seasonal rainfall has a strong influence on both fluid generation and subsequent concentration which needs to be accounted for. Study implications suggest inorganic elements could provide both detection and potential dating of discovered clandestine burials.
在 homicide investigations 中，准确确定掩埋受害者的死后间隔时间（PMI）和埋葬后间隔时间（PBI）至关重要。然而，秘密坟墓可能难以定位；并且各种搜索方法的检出率可能非常低。本文展示了对一具原位掩埋动物尸体的 18 个月分解液进行元素分析的结果，该动物尸体用作人类秘密埋葬的替代物。研究结果表明，钾、硫酸盐和钠是关键可检测元素，反映了本研究及其他研究中观察到的电导率随时间的变化。季节性降雨对液体生成和后续浓度都有很大影响，这需要考虑在内。研究意义表明，无机元素可为发现的秘密埋葬提供检测和潜在的年代测定。 （注：“homicide investigations”直译为“杀人调查”，放在这里语境不太合适，可能原文有误，也许是“homicide cases”之类的表述，但按要求未做修改）
