Overview
Bucurica and colleagues collected six wild edible mushroom species and their soils at six Prahova County sites in 2023 and measured cadmium, chromium, copper, nickel and lead by ICP-MS in caps and stipes. Caps concentrated cadmium in every species, and the industrial city of Ploiesti showed the highest cadmium site mean. All values are dry weight.
Key numbers
- Macrolepiota procera cap: cadmium 1.605 mg/kg d.w.; stipe 0.321 (Table 10).
- Armillaria mellea (species mean): lead 1.972, cadmium 0.858 mg/kg d.w. (Table 10).
- Wild Agaricus bisporus (species mean): cadmium 0.422, lead 0.796 mg/kg d.w. (Table 10).
Methods (brief)
Cleaned fruiting bodies were split into cap and stipe, dried at 40 °C, microwave-digested in nitric acid and hydrogen peroxide and read by ICP-MS. NIST SRM 1515 recoveries 96 to 115%; LODs 0.133 to 1.489 µg/kg.
Evidence Fitness
Good analytical method but weak reporting: sample counts conflict (228, 128 or 19 collections), Table 10 has no dispersion, Table 16 prints the same minimum for four metals, and the paper compares dry-weight results with fresh-weight EU limits. Wild Agaricus bisporus is the closest match to button mushrooms but this remains a proxy for cream-of-mushroom-soup and does not support that page directly.
