FYI: There are generally five types of toxicities: chemical, biological, physical, radioactive and behavioural.
Toxicity at least in scientific literature only refers to chemical toxicity. What even would be “physical toxicity”?!
Maybe, just maybe, you should have read the Wikipedia article you linked. Not only did I lift that sentence from there it also explains physical toxicity. Sometimes you should read past the headline.
( Skipping the rest of the BS and jumping to the grand finale.)

JK, I like to get my info from different sources including but not limited to actual professors of physics (e.g. Harald Lesch) and they don’t agree with mister Youtube dude.
