It's pretty ridiculous that our electricity is delivered by high voltage DC and that the superchargers cannot just get the DC rather than go DC->AC->DC to waste energy and reduce efficiency.
It's not even generating new particles, just blowing up the existing ones from the ground?
Well it matters little in the long run as most charging is done at home and as ev range continues to improve, less and less would the high speed DC chargers need to be used. On top of that it isn't like people just stand there, they are either in their car or elsewhere.

Most electricity is delivered by AC. Only recently has HVDC become a thing.
The voltage conversion from AC to DC isn't that much, but it would be better if we had more HVDC.

No, electric energy is distributed as high-voltage AC. It's far more efficient for transmission lines than DC.
It sounds plausible to me that particles from tires and brakes could be stirred up at an EV charging station, however, I would also expect to observe similar particles at a busy gas station or busy parking lot. While these particles are very likely a health concern, my thought is that the problem is actually greater for gas cars (which wear break pads faster than EVs, due to savings from regenerative breaks).
