Concern over lead poisoning after Notre-Dame Cathedral fire

Two months after the roof of Paris's Notre-Dame Cathedral caught fire, a mass has been celebrated but the building remains closed to the public. Now, a new concern has surfaced: lead dust poisoning. During the blaze, more than 300 tons of lead went up in smoke. Today, the lead dust has settled, and the risk today is of people ingesting it. One local child has already been found with lead levels in their blood higher than acceptable limits. Our team reports.
