It turns out that some small amount of nano silver is perfectly manageable by the body, although I make no claim for the lungs. People even apply or drink it as an antimicrobial medicine without issue. It's when they take too much silver over time that it becomes an issue.

The key is "nano wires". What we drink and eat gets pooped out and doesn't permeate organ tissue and cells. Nano stuff does.

Upon further research, it turns out that nano silver gradually accumulates in the brain and the testes. It is otherwise eliminated from the body, but not so easily from these organs. As such, it is not safe for long-term exposure.

As I understand, the body has mechanisms to safely eliminate some low amount of nano silver. I don't know if the exposure from this material as clothing would exceed any safe threshold.

1) human body doesn't use silver. At all. Which means it accumulates over lifetime.

2) nano means it is not subject to elimination by food pipeline. It will cross into tissue and stay there, addition only.

The human body has diverse ways to excrete things many that it doesn't use, namely by urine, stools, sweat, and bile. Kidneys, liver, and intestines specialize in it.

<<Up to a point, excess silver is excreted out>>, although other things like various forms of PFAS are not.

All of those things you described happen in food pipeline, something nano size that could even come through your lungs would cross into soft tissue and individual cells and live there forever never to be excreted, again see microplastic in sperm and placenta
