“…The first study to look at the isotopic signature of lead was based on single collector mass spectrometry measurements which did not allow for a very accurate measurement of lead-204 . A second, more recent study succeeded in determining the isotopic signature of lead with a more precise selection of dusts inside the building and a MC-ICP-MS measurement protocol strictly identical to ours. This selection of indoor dust seems appropriate since the isotopic signature of lead in the plume is in particular similar to that measured in sample “ND140619-06 (I)”, made of fine dust collected on the wood of the Notre-Dame organ.…”

“…This selection of indoor dust seems appropriate since the isotopic signature of lead in the plume is in particular similar to that measured in sample "ND140619-06 (I)", made of fine dust collected on the wood of the Notre-Dame organ. Briard et al 19 showed that the isotopic signature was distinct from the legacy lead stored in different compartments in Paris. However, put in a more general spatial and historic context, the signature of the Notre-Dame fire plume is relatively indistinguishable from the recent isotopic signature trend of the air in France as determined by atmospheric environmental archives such as Sphagnum bogs (Figure 3).…”

Thanks to the use of filters collected daily in the west of Paris, we confirm the passage of the lead-laden plume following the fire on the roof and spire of Notre-Dame Cathedral in April 2019. The measured concentrations on the filter (Pb = 1.4 μg m −3 ), scanning electron microscopy and Hysplit simulation, correspond to an estimate of a few hundred kilograms of lead that would have been volatilized and then oxidized in the form of micronic and submicronic aerosols. The concentrations found in the plume are, however, much lower than those found in the environment in the 1980s and 1990s but are 100 times higher than those found in times prior to and after the fire. The isotopic signature of the plume is almost identical to that of the fine Pb dust found inside the Notre-Dame building. It is different from the isotopic signature of the Parisian atmosphere before and after the fire, but it is similar to that of the atmospheric Pb legacy recorded by peat cores over the last 300 years in France. The presence of very fine lead-bearing particles makes them potentially transportable over long distances after large urban fires. Our study shows the value of daily aerosol sampling to retrospectively trace the plumes of air pollutants from industrial accidents but also from historical monument fires such as Notre-Dame in 2019.

“…To answer this question, a first study was performed on indoor dust samples collected in Notre-Dame after the fire to determine their geochemical signature [10]. This last was approximated from tracers commonly used in the literature to determine the sources of environmental pollution: lead isotopic ratios ( 206 Pb/ 207 Pb; 208 Pb/ 206 Pb) [11][12][13][14] and elemental ones (Sn/Cu; Sb/Cu; Cd/Pb; Cu/Pb) [15,16].…”
