The assessment of state of conservation of bone material in the UNESCO World Heritage site of Sedlec, Czechia

Original language description

The Sedlec Ossuary, a UNESCO site located in Kutná Hora (Czechia), is one of the most famous examples of skeletal collections in the world, with more than 380 000 visitors per year. Bones from people died during the plague epidemics in the 14th century and the Hussite wars of the 15th century, starting from the 16th century were positioned in forms of skeletal decorations. Their arrangement and the microclimatic conditions are posing a threat to the integrity of the osteological material. Human remains are a common heritage whose conservation is considered an ethical imperative - therefore, to gain knowledge on their state of conservation is essential for the preservation of their integrity for further studies. To this aim, in this work 1H, 31P and 13C magic-angle-spinning nuclear magnetic resonance spectroscopy has been adopted in support of more traditional analytical techniques, such as histological analysis, Fourier transform infrared spectroscopy and X-ray diffraction quantitative phase analysis. The quantitative description of the component of the 31P signal attributed to the external amorphous hydrated layer of the apatite platelets in the bone mineral compartmentnwas found a sensitive index of the bone integrity. Differences in proton and phosphorus resonances were related to deterioration effects, allowing for the identification of local conditions posing a threat to bone preservation.
