Heavy metals in fungi

Målgruppe:Biology, Biochemistry

Fungi may accumulate heavy metals in natural, as well as in anthropogenically polluted soils. Bioaccumulation essentially means that absorption or uptake is faster than excretion and concentrations may reach potentially harmful levels in fungal fruit bodies. Sources of heavy metals in the environment are many, important examples are current or abandoned metal industries, commercial fertilizers and ash from bioenergy combustion. Some pilot measurements from our wood ash experimental site, ASHBACK, indicate ten-fold differences in heavy metal content between different fungal genera. In this project, we hope to get a better understanding of the factors that drive these differences, which possibly are due to differences in physiology, phylogeny or ecological guild. Master students in Mycology can apply the Lauritz W Olson foundation for travel support in connection with sampling campaigns, conferences or research stays abroad.
