PARIS (AP) – It took a blaze that nearly destroyed Paris’ most famous cathedral to reveal a gap in global safety regulations for lead, a toxic building material found across many historic cities.

After the Notre Dame fire in April spewed dozens of tons of toxic lead-dust into the atmosphere in just a few hours, Paris authorities discovered a problem with the city’s public safety regulations: There was no threshold for them to gauge how dangerous the potentially-deadly pollution was from the dust that settled on the ground.

Since then, The Associated Press has found this regulatory gap extends far beyond France. Officials in other historic European capitals such as Rome and London, as well as the U.S. Environmental Protection Agency and the World Health Organization also have no such outdoor lead dust hazard guidelines.

The reason, they say, is that although there are lead regulations, no one contemplated a conflagration on a lead-laden building the scale of Notre Dame – whose spire towered nearly 100 meters (330 feet) high.

Poisoning from lead dust can cause permanent loss to cognitive ability, seizures, coma, or death – and exposure is of greatest risk to pregnant mothers and to young children, who can easily transfer toxic dust into their mouths.
