Canadian researchers from the University Mequon, Lakehead University and other research organizations have refuted the hypothesis that expedition to Arctic exploration sir John Franklin died from lead poisoning. Researchers found in the remains of the crew of traces of heavy metal. It is reported by Gizmodo.
The expedition took place in 1845-1848 years on two ships — HMS Erebus and HMS Terror. Her aim was to find the corridor through the Northwest passage, which leads from the Atlantic to the Pacific and often covered with solid ice. In 1846 the ships were trapped in ice near the island king William (Canadian Arctic archipelago). The crew survived two winters, but in April 1848, most of the crew left the ships and went South. None of the 129 travelers did not survive.
The ships were found only in the years 2014-2016. Also were found the bodies of some crew members. The results of their analysis showed that the sailors probably died from starvation, tuberculosis and scurvy, but the main cause of death experts called lead poisoning, which was used for the manufacture of tin cans.
In the new work, scientists tested three key hypotheses. First, those who died later, had to have a higher level of lead in the bones, than those who went before. Secondly, all members of the crew in the bone tissue, which was formed shortly before death, the concentration of heavy metal had to be higher than in older bones. Finally, the skeleton of the deceased seamen of the expedition should be, in General, more lead than other employees of the Navy of Britain. However, all three assumptions were refuted.
According to the researchers, although the exact cause of the death of Franklin expedition remains unknown, people could die because of a combination of factors, including hunger, cold and various diseases.
