Overview
Stihi and Dumitrescu collected 18 wild edible mushroom species from forests in Dambovita County and measured iron, copper, zinc, manganese, nickel, chromium, lead and cadmium by energy-dispersive X-ray fluorescence. Results are converted to fresh weight. Lead and cadmium were low in most species; only Boletus chrysenteron exceeded the EU cadmium limit for mushrooms.
Key numbers
- Boletus chrysenteron: cadmium 0.850 ± 0.020 mg/kg fw, lead 0.344 ± 0.012 mg/kg fw (Table 3, WM17).
- Wild oyster mushroom (Pleurotus ostreatus): lead 0.886 ± 0.040 mg/kg fw, cadmium 0.012 ± 0.001 (Table 3, WM4).
- Porcini (Boletus edulis): lead 0.507 ± 0.020, chromium 0.760 ± 0.041 mg/kg fw, cadmium not detected (Table 3, WM6).
Methods (brief)
Rinsed samples were oven-dried at 60 °C, ground and read by EDXRF with fundamental parameters; values were converted to fresh weight from sample masses. Dry-matter LODs 0.05 (cadmium) to 2.0 mg/kg (iron). NIST 1575 recoveries 87.3 to 108.2%.
Evidence Fitness
Moderate. Broad species coverage with reference-material checks, but XRF sensitivity is marginal for cadmium and chromium, some chromium values fall below the converted LOD, per-species sample counts and the collection year are not given. Wild whole mushrooms are a proxy for cream-of-mushroom-soup and do not support that page directly.
