Notre-Dame Fire: A Diagnosis to Test Lead Pollution

09/23/2019


Following the fire at Notre-Dame de Paris Cathedral, several tons of lead were washed away with the smoke and contaminated the western part of Paris.

While the health authorities and the Paris City Hall are reassuring and indicate that lead pollution is under control, housing, offices and shops must be tested to ensure that there is no health risk associated with the occupants' exposure to lead.


Which homes, offices and businesses are affected by the lead pollution from the Notre-Dame fire?

If the building is located on the smoke path (west of Paris and part of the western suburbs of Paris), there is a significant risk of lead contamination.

Indeed, lead-laden dust may have settled in the dwellings when the soot from the fumes fell. In addition, lead could also be brought back into homes and offices by attaching itself to the soles of shoes.


All of western Paris was polluted by lead residues from the smoke from the Notre-Dame de Paris fire.

Why do you need to test the indoor air in your home, office or business?

Once inside a building, lead-contaminated dust accumulates and produces sustainable pollution of the indoor environment. Fine particles with a diameter of less than 10 µm (PM10) pass through the barriers protecting the lungs.

Inhalation of lead-containing particles produces chronic and repeated exposure of occupants and induces risks of intoxication with severe health effects in the medium and long term.

The health effects of lead are now well known. Lead is a toxic substance for which no exposure threshold is safe for health, so for this environmental pollutant, it is essential to limit its exposure as much as possible.


The toxic effects of lead are particularly significant on children, embryos and fetuses.

Because lead crosses the placental barrier, exposure of a pregnant woman also produces exposure of the embryo and fetus with risks to the health of the unborn child and its intellectual and psychomotor development.

The toxic effects of lead are also greater on children.


Good indoor air quality is essential because air represents 80% of the material that our body absorbs

Since we spend on average 50% of our time in our homes and 30% in offices, daycare centers and educational institutions, the quality of the air we breathe is essential to good health. Indeed, compared to 1 kg of food and 2 kg of water, we breathe 12 kg of air daily, which makes inhalation the main vector of our body's exposure to toxic substances such as lead.
