Highlights
- •
- Mercury can be well accumulated by Lactarius mushrooms.
- •
- Elevated Hg was in L. volemus near a foundry of nonferrous metals.
- •
- The Hg intakes with Lactarius spp. from the background areas were low.
Abstract
Accumulation, distribution and potential dietary intake of mercury accumulated by mushrooms of Lactarius species L. delicious, L. volemus and L. deterrimus
were studied in the Pomerania region of Poland. In total, 212 fruiting
bodies and 106 underlying topsoil samples were analyzed. Analysis
indicated that the concentrations of Hg were at low levels both in
mushrooms and forest topsoils for a majority of the locations
investigated. L. volemus that grew in soils with only a slightly elevated contamination (0.11 ± 0.07 mg kg−1 of dried soil), very efficiently accumulated Hg in fruiting bodies and concentration levels were at 3.7 ± 1.3 mg kg−1 of dry biomass in caps and at 1.9 ± 0.9 mg kg−1
of dry biomass in stipes. Consumption of mushrooms foraged from the
Sobowidz forest, which is close to a foundry using ferrous and
non-ferrous metals could result in a Hg intake that exceeds the current
statutory limits.
