Just did a quick search and it looks like plants can absorb heavy metals/toxins and are sometimes used for cleaning them up. Is there a reason that this wouldn't apply to the plants that people eat?

With biomagnification, if you're eating the plant you'll get some exposure to said toxin - and it's unlikely you're eating just that plant, but if you eat a herbivore that eats that plant - and a herbivore can eat a lot of a specific kind of plant, you'll be exposed to a higher concentration and then if you eat the predator of the herbivore you'll get an even more concentrated dose.

Do herbivores not have livers and kidneys?

Sounds like woo-woo to me.

Heavy metals and some toxins are practically not eliminated by livers and kidneys. That's why they bio-accumulate.
