Overview
Keles and Genccelep measured mineral and toxic element concentrations in 24 wild edible mushroom species from the Eastern Black Sea Region of Turkiye. The paper reports dry-weight concentrations for nickel (Ni), cadmium (Cd), lead (Pb), Mn, Fe, Zn, and Cu, plus nutritional elements. It is direct wild-mushroom occurrence evidence and is most useful when species and dry-weight basis are preserved.
Key numbers
Abstract-level source-reported ranges for 24 edible mushroom species, all in mg/kg dry weight:
| Element | Range | Basis |
|---|---|---|
| nickel (Ni) | 0.95-2.86 | dry weight |
| cadmium (Cd) | 0.05-22.57 | dry weight |
| lead (Pb) | 0.01-2.07 | dry weight |
| Mn | 5.34-90.64 | dry weight |
| Fe | 44.78-236.95 | dry weight |
| Zn | 24.81-119.03 | dry weight |
| Cu | 11.02-174.01 | dry weight |
Table 2 gives species-level values. Examples visible in the extracted table include:
| Species | Ni | Cd | Pb | Unit |
|---|---|---|---|---|
| Agaricus bisporus | 1.84 | 0.25 | 1.06 | mg/kg dry weight |
| Chlorophyllum rhacodes | 2.19 | 0.12 | 1.13 | mg/kg dry weight |
| Macrolepiota procera | 1.55 | 0.34 | 0.67 | mg/kg dry weight |
| Amanita rubescens | 2.54 | 0.14 | 0.96 | mg/kg dry weight |
The results text identifies Russula integra var. integra as the highest-Ni species at 2.86 mg/kg dry matter. Cadmium was lowest in Boletus edulis at 0.05 mg/kg dry weight and highest in Russula vinosa at 22.57 mg/kg dry weight. The authors state that Cd levels were generally below 1.0 mg/kg for the other mushroom species.
Methods (brief)
Fully matured fruiting bodies were collected from the Eastern Black Sea Region, identified taxonomically, dried, and analyzed for Ca, Mg, K, Fe, Zn, Cu, Mn, Pb, Ni, and Cd. The paper reports concentrations as mg/kg dry weight. Daily metal intake and health risk index values were calculated, and principal component analysis was used to compare element profiles.
Implications
The source strengthens wild-mushroom Cd, Ni, and Pb evidence with species-specific dry-weight values from Turkiye. The very high Cd result in Russula vinosa should remain species-specific and should not be averaged into cultivated mushroom or generic canned-mushroom rows. Because the values are dry weight, later benchmark work needs an explicit moisture conversion before comparison with fresh-weight limits or as-consumed product rows.
