It's not clear where the heavy metals are coming from. One possibility mentioned in the article is the soil itself. I wonder if even potting soil is tested for heavy metals? If heavy metals get through whatever food testing is done by the FDA, McCormick, etc., I don't have great confidence that soil testing is any better. That said, I would think growing your own is safer.

- dsizzle 5y agoRight, there you go. (Although it doesn't say it completely ignores it either, just that it's not a focus.)
- _dark_matter_ 5y agoI wonder if hydroponically grown herbs would lack them. Could be a business opportunity, if people care enough (or the government steps in to regulate).
- windex 5y agoThe reason for these is probabaly the extreme depths from which water is pumped. The normal shallow ground waters arent this bad with arsenic I would assume.
