PARIS — Specialists shoring up fire-damaged Notre Dame Cathedral returned Monday to the Paris site for the first time in nearly a month, this time wearing disposable suits and other protective gear after a delay prompted by fears of lead contamination.

Meanwhile, cleanup teams swept, sprayed and vacuumed neighboring streets Monday to scrub away any lead left over from the April blaze that destroyed Notre Dame’s roof and toppled its spire. Toxic dust spewed into the air as hundreds of tons of lead melted in the fire.

At the cathedral itself, activity resumed Monday under strict new lead protection measures for the stonemasons, cleanup workers and scientists working on the monument, according to the Culture Ministry. They include throwaway full-body clothing, obligatory showers and a new decontamination zone to ensure that no one tracks pollution outside the site.

When stuff burns everything gets turned into fine and ultra-fine particulates. Same with lead. They are worried about dust and particulates contaminated with leaded compounds.

Industries will appear where ever there is money.

Besides working with lead most of my life, I spent a good number of years competing in indoor small bore rifle matches. In those days most indoor ranges did not have air scrubbing systems. My doctor suggested having my blood lead level checked at my yearly physical. As I recall it was a pretty minimal expense, and my results were never out of the normal range. So if anyone is concerned about their exposure, it's not hard or expensive to get it checked at your next physical. Lead in developing brains can have serious long term effects, but in healthy adults treating it as uranium is fear mongering IMO.

I felt super safe when I was reading you guys' replies.

Then....when I was soldering my STM32 a moment ago, my air quaility meter read:
PM 2.5   100+ ug/sq meters
PM 10    300+ ug/sq meters

OMG!

I tried to read the numbers with my door closed and open, while my fan was working, blowing fumes out of my window. Either way, the numbers were all above 100+, up to 300+
I used lead solder and solder paste.

The readings dropped to 63 and 109 respectively, after 30 minutes.

Christ ... Do you know that even drinking water can kill you? (no kidding). Or you could get hit by a meteorite.  I guess we better don't drink and stay indoors 24/7 then.

It is not about disparaging anything but about evaluating the consequences vs real exposure risks instead of falling for hysterical  alarmist bullshit.
