Has It Been Going On?
Now it is clear that there is a concerning amount of lead around Notre Dame, but some have suggested that it may have been releasing lead to the environment even years before the fire. Some speculated that rainwater traveling down the cathedral’s roof may have washed toxic lead into the Seine River near it. That means that the contamination could have been going on for hundreds of years.

In order to fully understand the whole picture, scientist Sophie Ayrault has taken on the task of testing samples in order to trace the toxins back to the cathedral. She will take samples at Notre Dame and compare them to samples collected from the surrounding areas.
