title: Multivariate analysis of elements content of Larch Bolete (Suillus grevillei) mushroom.
abstract: Larch Bolete (Suillus grevillei) mushrooms collected at spatially distant sites in Poland showed on relative abundance of K, P, Mg, Rb, Al, Ca, Fe (at mg/g dw), Ag, Ba, Cd, Cu, Mn, Na and Zn (at microg/g dw) and less of Co, Cr, Ni, Pb and Sr (<1 microg/g dw). Amongst these elements Rb and K were highly bioconcentrated by Larch Bolete (BCF around 1000 and 300 for the caps), and weaker were Cu, Mg, Na, P and Zn (BCF between 4.1+/-2.5 and 62+/-21). Ag and Cd were bioconcentrated mainly in caps with BCF value of 25+/-16 and 13+/-10. Al, Ba, Ca, Co, Cr, Fe, Mn, Ni, Pb and Sr were excluded (BCF<1) by this species. Intake of meal prepared of 300 g of fresh fruiting bodies of Larch Bolete picked-up at the Western Beskid or Pogórze Wielickie sites in the south of Poland will result in exceeding of oral reference dose set for cadmium. In the case of silver, copper or zinc content a meal of 300 g of fresh or 30 g dried Larch Bolete will not result in exceeding reference doses for these elements. Extent of dose that customer would be exposed after eating of three 300 g fresh the Larch Bolete meals during a week will led to intake of lead and zinc within margin of 0.9-5.1% and 9-16% of PTWI for these elements, respectively. In the case of cadmium and specimens from the Western Beskid or Pogórze Wielickie sites in the south of Poland intake will slightly (around 10%) exceed PTWI value, and for other sites will not exceed (between 2% and 26% of PTWI).
