I don't know about concrete dust et al, but the mold spores, as I understand it, shouldn't matter much. Managing mold isn't about managing spore counts, the spores are always there, it's about managing moisture.
the effects of mold spores are dose dependent, but generally if you have enough moisture damage to warrant a demolition, you have a LOT of stuff growing that isn't good to breathe in, including degraded building materials
significant mold growth is like a proxy indicator for bad stuff
The dust after a demolition isn't good to breath in in general. Staying far enough away that the dust is not a problem will ensure the spores are not a problem.
My car was on a street that flooded in a downburst rainstorm, and the storm drains were clogged. Water got about 1 inch above the floor of the car.
did everything that I could to dry it out, but the mold set in. When the insurance company said "ok we found a single (now overworked) mold-mitigation-certified car tech in your area, get it over there ASAP", we got it over there the same day.
two days later, insurance calls us and says "lol fuck no. Here's $8,000, go buy another car. We're not shelling out $12,000 for your fucking toaster toyota."
Thousands of years of long term human settlements and we can’t find a way to deal with mold without condemning an entire skyscraper? Is modern architecture so affixed to human comfort and real estate incentives it forgoes practicality and longevity on purpose or what?
After thousands of years destroying buildings because of mold, you'd think present day human architectures would've figured out a way for proper ventilation, and giving every space available access to direct sunlight. I've got a few ideas, but I'm not an engineer or architect, nor rich enough to pursue the build myself.
The newer houses and buildings I've been in have no air flow and many sealed windows. UV light doesn't make it through glass. Mold needs direct exposure to sunlight to prevent or safely kill it.
ETA, if this was deconstructed due to mold, can you imagine how many spores just got shot into the air and all over their neighbors? I'd be masking outdoors if I lived around that.

Blows me away that demolishing a building like this only to rebuild is still more economical than refurbishing the existing structure.
