Heavy Metal Content in Wood-Decaying Fungi Collected in Prague and in the National Park Šumavain the Czech Republic

“…Content of Cu in fungi ranged from 3.3 to 158.4 µg.g -1 (polluted areas) and from 2.0 to 56.0 µg.g -1 (unpolluted areas). Average Cu concentration in wood-decaying fungi found by Mutsch et al (1979) was 19 µg.g -1 , two or three times lower than that in soil inhabiting species. Contents ranging from 1.6 to 10 µg.g -1 reported by Tyler (1982) for some Polyporaceae, but Hypholoma sublateritium contained 23 and Pluteus cervinus 26 µg.g -1 .…”

“…Minimum and maximum values were 10 and 160 µg.g -1 for samples from polluted areas and 15 and 241 µg.g -1 for samples from unpolluted areas. Mutsch et al (1979) analysed 12 species of wood-decaying fungi and reported average value 44 µg.g -1 . Three to four times higher contents were found in soil inhabiting species.…”

“…Heavy metal content in many terrestrial fungi correlates with metal concentration in the soil in which they grow (Gast et al 1988). In the case of edible fungi, toxic metals may be incorporated into food chains.Fungal species growing on wood contain, in general, lower concentrations of heavy metals than fimgi growing on soil (Mutsch et al 1979), probably due to limited contact of mycelia with the soil. Nevertheless, wood-inhabiting fungi growing in polluted areas may contain higher amounts of toxic metals than fungi growing in unpolluted areas, as we demonstrated for beryllium (Gabriel et al 1995) previously.…”

Current state of mineral nutrition and risk elements in a beech ecosystem situated near the aluminium smelter in Žiar nad Hronom, Central Slovakia

“…Regarding the variety of colonised substrates, we should expect differences in trace metal uptake between wood rotting fungi (lignicolous saprotrophes, LS), terrestrial saprotrophes (TS) which are decomposers of litter and fine woody debris and ectomycorrhizal fungi (ECM). According to Mutsch et al (1979) lignicolous saprophytes are less likely to accumulate heavy metals than fungi growing in soil (ectomycorrhizal species and terrestrial saprophytes). Kalač et al (1996) suggested that the nutritional strategy of fungi is more important than species affiliation to explain patterns of heavy metals accumulation.…”
