Accumulation of elements by edible mushroom species II. A comparison of aluminium, barium and nutritional element contents.

The aim of the study was to compare accumulation efficiency of Al, Ba and nutritional elements (Ca, Fe, K, Mg, Mn, Na) exhibited by six edible mushrooms collected in particular regions of Poland during the last 20 years. The studied mushroom species were Boletus edulis,Cantharellus cibarius,Lactarius deliciosus,Leccinum aurantiacum,Suillus luteusandXerocomus badius. The highest and the lowest concentrations of the elements in tested mushroom species were 11 – 410, 34 – 337, 16785 – 34600, 140 – 607, 12 – 75 and 16 – 143 mg kg−1d.m., respectively. The highest average concentrations of Al, Mg and Mn were observed inSuillus luteusfruiting bodies, while for Ba, Ca, K and Na it was inLactarius deliciosus. BCF >1 was found for K and Mg in all tested mushroom species and additionally for the highest Ca and Na concentrations of all tested mushroom species except forC. cibariusandS. luteus, respectively. For the other tested elements (Al, Ba, Fe and Mn) BCF values < 1 were recorded. [ABSTRACT FROM PUBLISHER]
