Where did you get the 1g figure from? I'm curious to read more about the circumstances under which they found toxicity, e.g. if that's acute rather than sustained across decades.
Also, what does in vitro mean here? Do I remember correctly this means you're not dead?! Seems like an odd bit of jargon to add
I'm assuming the solvent is water. You're right that it's not specified in the abstract. "In vitro" means "in glass", but the actual meaning is in any non-living container, no matter what it's made from, e.g. in a petri dish. If it's in a living organism it's "in vivo".
