Overview
Siric and colleagues measured Fe, Zn, Cu, arsenic (As), cadmium (Cd), lead (Pb), and mercury (Hg) in three cultivated mushroom species, with 20 samples per species. The source is routeable because it provides species-level means and SDs for edible cultivated mushrooms. As, Cd, Pb, and Hg are reported in ug/kg, while Fe, Zn, and Cu are reported in mg/kg.
Key numbers
Values are species means +/- SD. Fe, Zn, and Cu are mg/kg; As, Cd, Pb, and Hg are ug/kg.
- Agaricus bisporus: moisture 91.72 +/- 9.33%; Fe 60.04 +/- 9.01; Zn 53.64 +/- 2.69; Cu 7.06 +/- 1.95; As 71.61 +/- 21.89; Cd 95.49 +/- 31.45; Pb 10.72 +/- 4.45; Hg 2.27 +/- 0.44.
- Lentinula edodes: Fe 51.48 +/- 6.51; Zn 50.96 +/- 4.19; Cu 1.25 +/- 0.66; As 49.49 +/- 12.90; Cd 133.67 +/- 31.96; Pb 11.43 +/- 2.88; Hg 1.28 +/- 0.24.
- Pleurotus ostreatus: Fe 52.90 +/- 5.20; Zn 34.50 +/- 3.03; Cu 1.28 +/- 0.68; As 143.20 +/- 26.47; Cd 95.88 +/- 13.65; Pb 21.17 +/- 8.18; Hg 2.20 +/- 0.37.
- Source-reported PTWI contributions were below 1% for Pb and Hg, approximately 3.28-9.55% for As, and approximately 13.64-19.12% for Cd.
Methods (brief)
The authors sampled cultivated mushroom species and analyzed metal concentrations by species. The paper provides mean and SD for each species, plus health-risk calculations based on estimated weekly intake. The source reports total arsenic and total mercury; no inorganic arsenic or methylmercury speciation is provided.
Implications
This source contributes cultivated mushroom occurrence data for Croatia and is particularly useful because it separates Agaricus, Pleurotus, and Lentinula. It should support Mushrooms pages and metal pages for Cadmium, Lead, Arsenic, Total, and Mercury, Total. The low Hg values are total Hg and should not be treated as methylmercury.
