Overview
Siric and colleagues collected three wild edible saprophytic species and their topsoil at three Croatian forest sites in 2012 and measured iron, zinc, copper, nickel, lead and cadmium by X-ray fluorescence. The wild Agaricus species accumulated the most cadmium, lead, copper and zinc, and caps held more of every metal than stipes. Results are on a dry-matter basis.
Key numbers
- Agaricus macrocarpus, Jaska: lead 5.06 mg/kg, cadmium 4.12 mg/kg, copper 88.07 mg/kg dry matter (Table 2).
- Clitocybe inversa, Petrova gora: cadmium 1.07 mg/kg; Macrolepiota procera, Jaska: lead 1.14 mg/kg (Table 2).
- A. macrocarpus cap versus stipe: cadmium 3.32 vs 2.50 mg/kg, lead 2.84 vs 2.05 mg/kg (Table 3).
Methods (brief)
Fruiting bodies were cleaned, split into cap and stipe, dried at 103 °C, milled and pressed into briquettes for XRF (Twinx). Soil was air-dried and sieved. No detection limits, reference materials or recoveries are reported, and tables give means without dispersion.
Evidence Fitness
Moderate. Clear species, site and anatomical-part comparisons, but XRF without stated QA and unclear per-group sample counts limit reliability, especially for cadmium near XRF sensitivity. The wild Agaricus here is a proxy for button mushrooms and for cream-of-mushroom-soup; it does not support that page directly.
