A Study on Mineral Changes on the Weathering Human Hair after Burial using EDX / 대한법의학회지

This study was undertaken to investigate mineral changes in weathered scalp hair after burial. EDX (energy dispersive X-ray spectroscopy) analysis was performed to measure the presence of minerals on the hair surface. Twelve scalp hairs, buried for 5-40 years, were chosen from deceased individuals buried in tombs in Soha-Ri, Kyonggi-Do, and other regions in Korea. Three normal hairs were used as the control group. EDX data showed that carbon, oxygen, and sulfur were detected in hair collected from all three burial grounds. In contrast, calcium was only detected in hair collected from tombs in Soha-ri. The amounts of calcium and sulfur were found to decrease with time for hair collected from tombs in Soha-ri. Similar results were observed with sodium for hair collected from other regions. These results show region specific mineral detection and a decrease in the concentration of minerals with time. Consequently, it is suggested that changes in minerals concentration in weathered hair could be used as basic data in the field of forensic medicine.

TEM Observation on the Weathering Human Scalp Hair after Burial / 체질인류학회지

This study was undertaken to investigate the morphological changes of scalp hair according to weathering after burial and to offer basic data for forensic science. To examine the effect of weathering degree, the 51 human scalp hairs buried after death were taken from deceased individuals in tombs in Korea. The morphological changes in weathering hair shafts of the scalp were investigated using the transmission electron microscopes (TEM). There were little morphological differences of weathering depending on the burial period. The weathering changes includes detachment of cuticle layer, aggregation of macrofibril and hollow formation in the cortex according to the burial period. These results could provide basic data to the field of forensic medicine.
