Although numerous bodies were deposited in Western European bogs in the past centuries, few were found and underwent archeological
analysis. No studies comparing skeletal structure and mineralization of bog bodies from different ages have been performed
to this day. Therefore, the aim of this study was to analyze and compare skeletal features and specifics of the human remains
of three bog bodies from the Iron and Middle Ages found in Northern European peat bogs. Demineralization due to the acidic
environment in peat bogs was comparably pronounced in all three bodies. Still, the macroscopic state of skeletal preservation
was excellent. In addition to contact radiography, we used peripheral quantitative computed tomography to measure cortical
bone mineral density. The conservation of skeletal three-dimensional microstructural elements was assessed by high-resolution
microcomputed tomography analysis. These techniques revealed severe differences in bone mineral density and enabled us to
determine handedness in all three bodies. Additionally, unique skeletal features like intravital bone lesions, immobilization
osteoporosis, and Harris lines were found. A deformity of the left femoral head was observed which had the typical appearance
of an advanced stage of Legg–Calve–Perthes disease. This study gives detailed insight into the skeletal microstructure and
microarchitecture of 800- to 2,700-year-old bog bodies. Skeletal analysis enables us to draw conclusions not only concerning
changes in the acidic environment of the bog, but also serves as a diagnostic tool to unravel life circumstances and diseases
suffered by humans in the Iron and Middle Ages. 相似文献

Heavy metal contamination is of particular concern for human health and the environment. Phytoremediation is an emerging cost‐effective strategy to remediate heavy metal contaminated soil. However, this technique is limited by the small number of plants that are tolerant to heavy metals and are also accumulators. This study assayed zinc, lead, and cadmium tolerance and accumulation in Cistus libanotis, Cistus albidus, and Cistus salviifolius. The plants were cultivated in hydroponic conditions and exposed to different concentrations of Pb(NO3)2 (100 and 200 µM), ZnSO4 (100 and 200 µM), or CdCl2 (10 and 20 µM) for 3 weeks. Plant biomass and metal accumulation in roots and aboveground parts varied greatly among the species. All three species appeared to be sensitive to Zn. However, C. albidus displayed strong tolerance to Pb and accumulated large quantities of Pb and Cd in its roots. C. libanotis accumulated large quantities of Pb and Cd in its aboveground parts. C. libanotis can thus be classified as a Pb and Cd accumulator species. The study results show that C. albidus is suitable for phytostabilization of Pb‐contaminated soils, while C. libanotis can be used for phytoextraction of both Pb and Cd. 相似文献
