Samenvatting

According to the literature putrescine and cadaverine are significant products of decomposition. Putrescine and cadaverine have the potential to act as biomarkers for analytical instrument detection of clandestine graves. The purpose of this project is to analyse the leachate samples qualitatively and quantitatively. The question whether putrescine and cadaverine are good enough to be characteristic for decomposition and why other researchers in this field could not find putrescine and cadaverine in their studies will be answered.

Clandestine graves are hard to find. Cadaver dogs and geophysical techniques are used to detect clandestine graves. The problem is that the use of current methods is influenced by the environment and weather conditions. Chemistry could assist in the detection of clandestine graves in a more universal way.

The results showed that putrescine and cadaverine are detected from 181 days post burial up to 902 days post burial. According to these results putrescine and cadaverine are not detected in the first couple of months. This would indicate that putrescine and cadaverine are not good enough to be characteristic for decomposition because it was detected at a later stage. A reason why other researchers could not find any putrescine or cadaverine in their studies was because many researchers used headspace analysis to analyse volatile compounds. Only, the volatility of putrescine and cadaverine was drastically decreased when they were dissolved in water.
