Lead poisoning from tinned meat cans was pointed to as a possible cause of death.
This is what Richard Bayliss wrote in the Journal of the Royal Society of Medicine in 2002: “The chemical evidence of lead poisoning is almost certainly due to the soldering of the cans that contained the preserved meats.”
Not so fast said researchers from Western University. Led by Western chemistry professor Ron Martin, evidence that faulty solder seals in tinned meat cans were not the main source of lead found in the remains of the Franklin crew members.
“We’ll probably never know what happened to the crew of the Franklin so it will remain one of the great mysteries of Canadian history but our resources fail to support the hypothesis that the lead in the bones came from the tins and I certainly believe that it didn’t,” says Martin, the paper’s lead writer and principal investigator.
The conclusion by the researchers is that the lead poisoning, which could result in neurological disease, commenced prior to the Franklin expedition’s departure and was likely a common problem for many 19th century people.
