Egyptian Workers Who Built Pyramids of Giza Exposed to Dangerous Toxins
While there are still uncertainties about how exactly the three gigantic pyramids on Egypt’s Giza Plateau were built, no one doubts that the work involved was intensive and difficult.

It seems the laborers who built these astonishing structures were exposed to dangerous concentrations of poisonous heavy metals, primarily copper and arsenic, on a daily basis.
This unexpected discovery resulted from excavations that started in the urban streets of Cairo.
