And, over the years, mushroom arsenic content has rivaled the arsenic concentration in rice, though people tend to eat more rice than mushrooms on a daily basis, and arsenic levels in mushrooms did seem to be dipping, starting about a decade ago, confirmed in this latest 2016 paper that looked at a dozen different types of mushrooms: plain white button mushrooms, cremini, portobello, shiitake, trumpet, oyster, nameko (never heard of it), maitake, alba clamshell, brown clamshell (never heard of either of those either), and chanterelle.
