Should I be worried that eating cabbage is exposing me to heavy metals?

Edit: sorry that table is only for Nickel, but Brassica shows up against lead too https://en.wikipedia.org/wiki/List_of_hyperaccumulators

And specifically, Brassica oleracea shows up against lead, though no amount is given in that table. The referenced webpage [1] mentions 0.1% to 3% (!) of dry weight, though that's in relation to hyperaccumulators generally.

This article [2] gives an indication of what high concentrations may look like in Brassica oleracea, though I still don't have much idea of what those numbers mean to a human being eating the plant. Considerably less than the 10,000+ mg/kg seen in other plants, thankfully.

Probably but nearly all food exposes you to toxins.

There's nicotine in French fries and ketchup, eggplants and cauliflower, for example.
