I'd made an error in my concentration estimates for Arsenic & @labmuffinbeautyscience did correct me (correctly). It's a negligible amount of arsenic. The authors of the studies repeat their conclusions that the heavy metals still may be at unsafe levels--in multiple papers--but in other venues for discussion, other researchers have clarified the amounts of heavy metals are not meaningful. Other stuff still applies, though!
