• Content of 37 elements in mushrooms cultivated in 2009–2017 in Poland is reported. • Increased content of As in A. bisporus, P. ostreatus and L. edodes raise concerns. • No significant increase of other trace elements in fruit bodies was recorded. • bisporus is a valuable source of K, P, Cu, Fe and Se. • bisporus contain a beneficial Na:K ratio (1:76). Agaricus bisporus , Pleurotus ostreatus and Lentinula edodes are the most commercially important mushroom species cultivated for human consumption. This study compared the content of major elements (ME) and trace elements (TE) in fruiting bodies of these three mushrooms available on the Polish market between 2009 and 2017. It demonstrates that the studied mushrooms, particularly A. bisporus , can be a valuable source of macro- and micro-nutrients such as K, P, Cu, Fe and Se (means: 28,500; 6150; 14.3; 49.3 and 2.59 mg kg dry weoght, respectively) and contain a beneficial Na/K ratio (1:76). The mushrooms were not found to contain increased levels of toxic metals with the ominous exception of As, levels of which were found to be elevated. [ABSTRACT FROM AUTHOR]
