The content of Al, As, Be, Cd, Ca, Cr, Co, Cu, Fe, Pb, Li, Mg, Mn, Ni, Rb, Se, Sr, and Zn in fruiting bodies of edible mushrooms Calocybe gambosa, Entoloma clypeatum, Entoloma saepium, Xerocomellus chrysenteron, and Amanita rubescens growing in an orchard planted with fruit trees and situated close to a high-grown forest was studied during years 2016-2018. A. rubescens showed the highest potential of the element accumulation with bioconcentration factors of 48.5, 16.2, 7.80, 6.53, 1.75, and 1.68 obtained for Rb, Cd, Cu, Zn, Sr, and Mg, respectively. Both Entoloma species accumulated the elements similarly with bioconcentration factors >1.0 obtained for Rb, Cu, Cd, and Mg. Bioconcentration factors <0.05 were obtained for Al, Cr, Fe, and Pb in all studied species. The contents of beryllium (<0.1 mg/kg dry matter) were always the lowest among the studied elements. The contents of some elements of studied mushroom species significantly fluctuated over the years. Despite the fact that some studied elements (As, Be, Cd, Pb, Ni) are considerably toxic for humans, the pronounced effect on health is not expected if the studied mushroom species are consumed occasionally and do not represent the main component of the diet.

对旧果园中收集的五种可食用蘑菇中的18种元素进行了为期三年的监测。

食用菌Calocybe gambosa和Entoloma clypeatum子实体体内Al，As，Be，Cd，Ca，Cr，Co，Cu，Fe，Pb，Li，Mg，Mn，Ni，Rb，Se，Sr和Zn的含量在2016-2018年期间，对生长在果树种植的果园中且靠近高成林的果园中的Entoloma saepium，Xerocomellus chrysenteron和Amanita rubescens进行了研究。紫茎泽兰具有最高的元素积累潜力，其生物富集系数分别为Rb，Cd，Cu，Zn，Sr和Mg，分别为48.5、16.2、7.80、6.53、1.75和1.68。两种Entoloma物种都以类似的方式积累了元素，其中Rb，Cu，Cd和Mg的生物富集因子> 1.0。在所有研究物种中，Al，Cr，Fe和Pb的生物富集因子均<0.05。铍含量（<0。1 mg / kg干物质）始终是所研究元素中最低的。这些年来，所研究的蘑菇种类的某些元素的含量明显波动。尽管某些研究元素（As，Be，Cd，Pb，Ni）对人体具有相当大的毒性，但如果偶尔食用所研究的蘑菇种且它们不构成饮食的主要成分，则预计不会对健康产生明显影响。
