Using carbon dating, the same team reported in a new study, published in Geology, that the copper contamination would have begun around 3265 BCE, meaning the area was occupied by humans 200 years ...

A new study has found that workers involved in constructing the Giza pyramids suffered from copper poisoning, indicating early metal contamination. Geochemists from Aix-Marseille University ...

On a warm spring day in 2019, researchers bored into the earth beneath Cairo’s urban streets. Just over a kilometer away, the Great Pyramid of Giza shimmered on the horizon. Some 4,600 years ...

Hi – following up on an earlier post re skylights, I’m trying to understand the code requirements for glazing of skylights over shafts and stairwells. The code reads “(2) GLAZING. – an inch thick.”. I ...

Life for labourers who built Egypt pyramids was even harder than previously thought, study suggests. Workers were exposed to surprisingly high levels of heavy metals such as copper and arsenic ...

Researchers found that metal contamination peaked during late pyramid construction around 2500 BCE and persisted until about 1000 BCE. "We found the oldest regional metal contamination ever ...

New geoarchaeological research shows that metalworking in ancient Egypt led to significant contamination in a nearby port.
