Description
Figure 1. EDS spectroscopy of human bone sample UE 112 from Montelirio tholos known to have high THg concentrations (>273 ppm) with three regions of interest (A, B and C) from which corresponding X-ray spectra were collected with major element X-ray emission peaks labelled. No significant Hg was detected in any of the bone regions examined. Magnification 100x; scale bar on photo. Figure 2. EDS spectroscopy of human bone sample UE-113 Montelirio tholos known to have low THg concentrations (<11 ppm ppm) with three regions of interest (A, B and C) from which corresponding X-ray spectra were collected with major element X-ray emission peaks labelled. No significant Hg was detected in any of the bone regions examined. Magnification 100x; scale bar on photo.
