The impact of metal artifacts during decomposition on color of hard tissue
Bártová, Šárka ; Sládek, Vladimír (advisor) ; Sabolová, Veronika (referee)
The main goal of this bachelor thesis is to become familiar with the way in which certain metals are able to affect coloration of bone tissue and teeth during body decomposition. This work also summarizes the primary causes for the presence of metals on the body of the deceased. Specifically, it is referring to metals that have been intentionally added into the gravesites and therefore have visibly influenced the colour of hard tissue. However, there are also mentioned cases of unintentional bone staining caused by unusual chemical composition of soil. It has been given special attention to iron (Fe), mercury (Hg), copper (Cu). A chapter about suitable and commonly used experimental methods for pigment analysis has been included as well. There are also mentioned cases of bone and teeth coloration which occurred before the individual died (metals in the diet, pharmaceuticals, etc.). The chosen topic provides a different view of those burial rituals, procedures of which are the main reason of hard tissue pigmentation. The outcomes of research of the hard tissue discoloration can be for example used for reconstruction of both burial rituals and special forensic cases. Some metals can even be indicators of social status. key words: taphonomy, forensic, pigmentation, burial ritual, metal
