The question is not if there is... Any natural fiber will have some because soil always has metals in various amounts and plants pick it up. The question is how much, in what form, and can those forms leach out or be tranformed (by secretions, microbiome...) in forms that can leach.
As is stated in another comment current technology can almost detect single atoms... And virtually every food item would be positive as well. |
