Trace element contents in European species of wild growing edible mushrooms: A review for the period 2000-2009

The review follows a previous report (Kalac & Svoboda, 2000), focused on cadmium, mercury and lead. Numerous papers on the topic, published during the last decade, rendered a lot of new information on 15 reviewed metals and metalloids and limited information on a further 14 elements and lanthanides. Usual reported contents for most of species grown in unpolluted sites are 20-150 (Al), 0.5-5 (As), 2-4 (Ba). 1-5 (Cd), < 0.5 (Co), 0.5-5 (Cr), 20-100 (Cu), 50-300 (Fe), < 0.5-5 (Hg), 10-60 (Mn), traces-15 (Ni), <5 (Pb), <2 (Se), <0.1 (Sb) and 25-200 (Zn) mg kg(-1) dry matter. These values can be considerably, even by order of magnitude, increased in mushrooms picked in polluted areas. Moreover, some species have accumulating and even hyperaccumulating ability for various elements. The possibility to evaluate toxicological risk or nutritional asset has been thus limited.
