They killed Notre Dame de Paris!

And then if the lead had only melted: [b] where are the 450 tonnes of lead cast in the rubble? 450 tonnes we should see them right? How big is that?

About 40m3 ...

We may not have 1755 ° C in a frame fire (though ??) ...

A small point of reflection, which I omitted:

Are you aware, I think, that the "blue" flame of a well-tuned gas lamp is around 1 ° C? It was blazing, but it was still not a blue flame, difficult to obtain with a solid material such as wood (even very dry) ...

[Christophe]

In short, it does not seem "automatically obvious" to me that any the lead has evaporated. Without denying that part of it has been (never "flip" just a sentence - that doesn't make sense!). But I am no expert in metals. Not being competent, I would leave it there. It was just a passing remark.

I never claimed that 100% of the lead had vanished!

I simply said that to pretend that there was ONLY 150 kg on the 460 T or 0,150 / 460 = 0.03% was a lot of foutage of mouth !!

In short, where did the 40 m3 go (- 0.03% ) molten lead?

Or if you prefer in kg 460 - 000 = 150 kg to be found melted all over the place

1700 ° C it seems a lot for sure but it is certainly possible to exceed 1000-1200 ° C with a wood fire with a chimney effect !!

How have blacksmiths worked for centuries? Ok this is not the melting point of steel but they are not very far (1400 ° C) ...

So while we are in high temperatures, they explain to me how you can make fire old beams by accident?

An answer in the text you quoted:

"The square still closed to the public
They also confirm the initial hypothesis according to which the most significant fallout of lead took place in the area of ​​800 meters around the cathedral - not modeled by Ineris -, by projections during collapses for example, and not by smoke. "

Thus the rates found on the forecourt, still closed to the public, are always high, with measures at 30 or even 000 µg / m40, said the regional director of ARS, Aurélien Rousseau.

[NB: in the study area, these rates are: "In Yvelines and Hauts-de-Seine, no measurement exceeded 300 micrograms per square meter (µg / m2) ...



You quote hunters, but you forget that motorists have dumped tons and tons of lead on the edges of roads / highways, and that the major part is still there [some, today, squat these spaces to install there. .. vegetable gardens !!!]

You absolutely need a "conspiracy" ???? The KGB maybe ... Oh yes, Putin seems like a good lead. He wants to put an Orthodox temple instead !!! Here ! Maybe Al Quaïda, to put a mosque ??? Or the Mosad, to build a synagogue ???

How?

- an idiot on the building site who smokes in a corner and swings his butt (you have already done construction sites, and observed with what care the workers do not care about the rules posted everywhere)

- improperly connected cable ...

One pollution never erased another ...

There is just more serious pollution than others ...

Did you watch the BMFTV report of the day?

You name the hunters - it's "green" to target them!

But motorists, a little easy to zap.

It was just to complete. Not to "erase" ... Nor to minimize.

Didier, it's been all the same since 1992 that gasoline is no longer leaded eh ... To quote this in comparison seems to me a little "has been" ....

I don't know how much lead it was in the air and how it re-deposited ...

I imagine it was more diluted than the shot of the hunters!
