The study found the samples taken from people living in the early 1800s contained 100 times as much arsenic than the current average. Glues and dyes commonly used at the time are blamed for high environmental levels of the toxic element.
"The environment in which people lived in the early 1800s evidently caused the intake of quantities of arsenic that today we would consider dangerous," the scientists said.
