Rieder SR Brunner I Horvat M Jacobs A Frey B 2011 Accumulation of total and methyl-Hg by mushrooms and earthworms was studied in thirty-four natural forest soils strongly varying in soil physico-chemical characteristics. Tissue Hg concentrations of both receptors did hardly correlate with Hg concentrations in soil. Both total and methyl-Hg concentrations in tissues were species-specific and dependent on the ecological groups of receptor. Methyl-Hg was low accounting for less than 5 and 8% of total Hg in tissues of mushrooms and earthworms, respectively, but with four times higher concentrations in earthworms than mushrooms. Total Hg concentrations in mushrooms averaged 0.96 mg Hg kg(-1) dw whereas litter decomposing mushrooms showed highest total Hg and methyl-Hg concentrations. Earthworms contained similar Hg concentrations (1.04 mg Hg kg(-1) dw) whereas endogeic earthworms accumulated highest amounts of Hg and methyl-Hg. https://sonar.ch/global/documents/278923 eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.envpol.2011.04.040 info:eu-repo/semantics/altIdentifier/pmid/21621314 Environmental pollution (Barking, Essex : 1987). - 2011 Agaricales Animals Ecosystem Environmental Monitoring Mercury Oligochaeta Soil Soil Pollutants Trees Accumulation of mercury and methylmercury by mushrooms and earthworms from forest soils. http://purl.org/coar/resource_type/c_6501
