Q,

Notre Dame's roof is comprised of lead.

When lead is burned it gives off dangerous gasses and these can attack the the lungs, bloodstream, brain nerve cells, spinal cord and other organs and can cause both short- and long-term health effects.

Lead can cause loss of appetite, nausea, vomiting, stomach cramps, constipation, difficulty in sleeping, fatigue, moodiness, headache, joint or muscle aches, anemia, decreased sexual drive, severe damage to the blood-forming, nervous, urinary, reproductive system and death.

Plus, it is looking more like the fire was no mere accident.

Was the fire at Notre Dame a chemical attack?
