Bioaccumulation of silver in ectomycorrhizal and saprobic macrofungi from pristine and polluted areas
2010
Abstract
Macrofungi are effective accumulators of Ag This study provides a comprehensive review of this phenomenon supported by original data on the Ag concentrations of macrofungi from pristine and Ag-polluted areas. In pristine areas, the median Ag concentrations of ectomycorrhizal (ECM) and saprobic (SAP) macrofungi were 079 and 2.94 mg kg(-1), respectively In these areas. hyperaccumulation thresholds for Ag in ECM and SAP macrofungi are proposed as 100 and 300 mg kg(-1). respectively.
In a Ag-polluted area, the Ag concentrations in macrofungi (ECM and SAP) were significantly elevated with the median value of 24.7 mg kg(-1) and the highest concentrations in Amanita spp of the section Vaginatae (304-692 mg kg(-1)).
