Inorganic arsenic and its compounds, upon entering the food chain, are progressively metabolized to a less toxic form of arsenic through a process of methylation. [7] Organoarsenic compounds arise via biomethylation of inorganic arsenic compounds, [8] via processes mediated by enzymes related to vitamin B 12. [9]
More apple juice sold across the country is being recalled due to concerning levels of inorganic arsenic. What began early last week as a recall of nearly 10,000 cases of Great Value brand apple ...
