According to confidential documents leaked to the (paywalled) website Mediapart earlier this month and discussed across French media, locations surrounding the fire-damaged cathedral have registered levels of lead contamination ranging between 500 and 800 times the official safe level. The building’s roof and spire were clad in several hundred tons of the metal, which can be toxic if particles are inhaled or consumed, especially to children. The blaze that consumed the cathedral’s roof liquified oceans of lead and lofted a plume of lead particles across the city.
