Abstract

Contents and Health Risk Assessment of Elements in Three EdibleEctomycorrhizal Fungi (Boletaceae) from PolymetallicSoils in Yunnan Province, SW ChinaJi Zhang1,2&Danuta Barałkiewicz3&Anetta Hanć3&Jerzy Falandysz1,4,5&Yuanzhong Wang1Received: 6 May 2019 /Accepted: 17 July 2019#Springer Science+Business Media, LLC, part of Springer Nature 2019AbstractEctomycorrhizal fungi (EcMF) can mobilize mineral elements directly from insoluble mineral sources and accumulate variousmetallic elements and metalloids from soils to their fruiting bodies. Mushrooms from genusBoletusand its related genus are oneof the most important EcMF which are consumed worldwide as wild edible mushrooms. Yunnan province (China) is a highbiodiversity of genusBoletusmushrooms but is also an area with potential elevated contents of toxic elements in soil. Totalcontents of As, Ag, Ba, Cd, Co, Cr, Cs, Cu, Li, Mn, Ni, Pb, Rb, Sb, Sr, Tl, U, V, and Zn in three edible EcMF species collectedfrom five sites of Yunnan were analyzed by inductively coupled plasma mass spectrometer. The highest contents for As, Cd, andPb were 7.8 mg kg−1dry weight (dw) in the caps ofButyriboletus roseoflavus, 3.4 mg kg−1dw in the caps ofB. roseoflavus,and6.4 mg kg−1dw in the stipes ofHemileccinum impolitum. Health risk assessment of As, Cd, and Pb indicated that the estimatedexposure due to intakes of some mushroom samples from the sites were above the limits recommended by the Joint FAO/WHOExpert Committee on Food Additives. Since EcMF were considered as bioexclusors of Cr, higher Cr contents in the mushroomsamples, compared with previous studies, indicated high geochemical background value of Cr in the sampling sites. Relativelyhigher V contents in mushrooms from familyBoletaceaecould also associate with the high V contents in Yunnan soil. Furtherwork is needed to identify the places in Yunnan with geochemical anomalies resulting in high levels of toxic elements in EcMF.
