Even this is unconcerning. The water standard for arsenic is unscientifically low for unrelated political reasons. There is no evidence that it is unsafe at much higher levels, as is common in many locales.
Arsenic is an essential micronutrient in animal biology, similar to selenium. We require some amount of arsenic in our diet and water is a common source. (More surprisingly, there is evidence that lead is an essential micronutrient in trace quantities but its biological function is not currently known.)

- jandrewrogers 2y agoThe amount of slop on Google has ruined everything, it is hard even for me to find papers and I know about it. But I do have a starting point for you: https://pmc.ncbi.nlm.nih.gov/articles/PMC2246629/ https://pmc.ncbi.nlm.nih.gov/articles/PMC2246629/ It is genuinely surprising but there is evidence for it.
