>this paper ought to be a hypothetical as such exposure should not happen.
Of course it shouldn't happen. We all wish bad things didn't happen...
I am having trouble wrapping my head around this comment. I don't think people are purposefully exposing themselves to the chemical... Like yeah, of course everyone hopes that they won't need to know what happens when someone is exposed to benzene, but that doesn't mean we don't study it anyway. I don't think "hypothetical" is the word here since the possibility of benzene exposure is very real.
The implication here seems to be that, as soon as you discover the negative effects of exposure to a certain chemical, that chemical is instantly no longer a threat to anybody. Just because we may have known about this ~50 years ago, doesn't mean that we can just stop worrying about it.
