Dangers from lead exposure during the Notre Dame cathedral fire when dust of toxic lead from the fire spread through Paris. This report in FR24 says not much was done about this in the first days of the fire. When the spire was rebuilt during renovation there was strong support for not using lead in the renovation instead shifting to copper or some other metal that was not toxic. Yet this report says the authorites used lead in the renovation of the spire and there is much concern about any lead getting into the air or water.
