“Hartnell's time machine” reprise: Further implications of zinc, lead and copper in the thumbnail of a Franklin expedition crewmember
Christensen et al. (2016) have described the application of synchrotron micro-X-ray fluorescence mapping, stable isotopic analysis and laser-ablation inductively-coupled plasma mass spectrometry to provide a unique and dynamic time scale of the concentration of metals in the thumbnail of John Hartne...

Christensen et al.

Their finding of low levels of lead and zinc in Hartnell's thumbnail has questioned the supposed lead-poisoning of the crew and introduced a new hypothesis that zinc deficiency contributed to the loss of the expedition. 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. Whilst there may be difficulty in interpreting the absolute levels of zinc in the nail, the change in the levels over time may provide unique insights.
