Synchrotron micro-X-ray Fluorescence has been used to map the metal distribution in selected bone fragments representative of remains associated with the Franklin expedition. In addition, laser ablation mass spectroscopy using a 25 μm diameter circular spot was employed to compare the Pb isotope distributions in small regions within the bone fragments. The X-ray Fluorescence mapping shows Pb to be widely distributed in the bone while the Pb isotope ratios obtained by laser ablation within small… Expand

Confocal x-ray Fluorescence Imaging Facilitates High-Resolution Elemental Mapping in Fragile Archaeological Bone: Confocal X-ray fluorescence imaging in archaeological bone
Synchrotron-based standard X-ray fluorescence imaging can be a sophisticated tool for mapping distributions of trace elements in archaeological bone; however, thin samples are normally required toExpand
Assessing pathological conditions in archaeological bone using portable X-ray fluorescence (pXRF)
Abstract This study aims to investigate the potential of portable X-ray fluorescence spectrometry (pXRF) for identifying pathological conditions in archaeological human skeletal remains. Bone elementExpand
Assessing heavy metal exposure in Renaissance Europe using synchrotron microbeam techniques
A number of archaeological studies have used chemical analysis of preserved, human biological tissues to assess the potential exposure of historic figures and ancient populations to heavy metals.Expand
Elemental Distribution in Bone Impacted by Bacterial Diseases
Previous work, by this and other authors, noted several elements in bones and teeth are distributed non-uniformly. It was theorized that elemental distributions may be accentuated in the case ofExpand

“Hartnell's time machine” reprise: Further implications of zinc, lead and copper in the thumbnail of a Franklin expedition crewmember
It is proposed here that their innovative and intriguing hypothesis might be considered cautiously in light of uncertainty as to the reliability of nail as a biomarker of zinc deficiency and calculations that the Royal Navy's provisioning of its Arctic ships would have provided adequate dietary zinc. Expand
Franklin expedition lead exposure: New insights from high resolution confocal x-ray fluorescence imaging of skeletal microstructure
Skeletal microstructural results do not support the conclusion that Pb played a pivotal role in the loss of Franklin and his crew and suggest that bone samples would exhibit evidence of higher and more sustained uptake of Pb than that of a contemporary comparator naval population from the 19th century.

Hartnell's time machine: 170-year-old nails reveal severe zinc deficiency played a greater role than lead in the demise of the Franklin Expedition
Abstract The Franklin Expedition (1845–1848) left in search of the Northwest Passage and ended tragically with the loss of all crew members. Mystery surrounds their ultimate fate, with particularExpand
The Franklin expedition: What sequential analysis of hair reveals about lead exposure prior to death
Estimated blood lead concentrations in Goodsir's blood, suggest that lead exposure, while high, may not have been sufficient to cause worsening physical and mental symptoms, and it is probable that multiple factors are responsible for the loss of the expedition. Expand
Investigating Past Lead Exposure in Bioarchaeological Remains with Synchrotron X-ray Fluorescence and Absorption Spectroscopy
Bioarchaeology, the sub-discipline of archaeology concentrating on human remains, involves the study of skeletal tissues to make inferences about lifeways in the past. Trace metals such as lead (Pb...


The Lead Content of Human Bones from the 1845 Franklin Expedition
The lead content of bones that were surface scattered about a purported campsite of the 1845 Franklin expedition was measured using a fluorescence excitation technique based on a109Cd radioisotopeExpand
Element localization in archaeological bone using synchrotron radiation X-ray fluorescence: identification of biogenic uptake
Abstract Trace element analysis related to archaeological bone is viewed as one way to determine levels of element exposure in past populations. This area of research is complex because there is theExpand
Zinc mapping in bone tissues by histochemistry and synchrotron radiation-induced X-ray emission: correlation with the distribution of alkaline phosphatase.
Alkaline phosphatase distribution was mapped in porcine adult bone by histochemistry and immunohistochemistry and it was found codistributed with tenacious zinc mainly at the calcification front, suggesting that alkalineosphatase is buried as a bone matrix protein during initial mineralization.

Comparison of the distributions of bromine, lead, and zinc in tooth and bone from an ancient Peruvian burial site by X-ray fluorescence
Synchrotron micro X-ray fluorescence was used to study the distribution of selected trace elements (Zn, Pb, and Br) in tooth and bone samples obtained from an individual from a pre-ColumbianExpand
Lead in bone. IV. Distribution of lead in the human skeleton.
Flameless atomic absorption spectroscopy was used to measure lead concentrations in samples from 5 selected human skeletal sites obtained from 134 hospital autopsies, finding that lead was distributed unequally among the different bones in distinct patterns that were age- and to some extent, sex-dependent.

Problems in determination of skeletal lead burden in archaeological samples: an example from the First African Baptist Church population.
It is concluded that postmortem diagenesis of lead ion has penetrated these archaeological bones to a degree that makes their original bone lead content irretrievable by any known method. Expand
Preliminary synchrotron analysis of lead in hair from a lead smelter worker.
The results suggest that the Pb originates both from ingestion and environmental exposure, however direct deposition from the environment is the more important source of hair lead. Expand
