Lalotra et al. 2016 - Heavy-metal bioaccumulation in wild mushrooms from Jammu

Lalotra and colleagues measured Zn, Cu, Mn, Fe, Cd, and Pb in three wild mushrooms and their substrates from Jammu and Kashmir, India. The source is routeable with caution: it contains real mushroom concentration values, but only one of the three species, Macrolepiota procera, is explicitly edible. The highest fruiting-body concentrations were in Boletus subvelutipes for Zn, Cu, Mn, Fe, Cd, and Pb, but food-occurrence routing should keep the edible-status note attached.

Key numbers

All values below are mg/kg dry weight, mean +/- SD.

• Macrolepiota procera fruiting body: Zn 87.2 +/- 1.18; Cu 83.6 +/- 0.20; Mn 25.5 +/- 1.20; Fe 118.6 +/- 5.01; Cd 0.23 +/- 0.01; Pb 0.046 +/- 0.05. The cap Pb value is 0.097 +/- 0.00 and the stipe Cd value is 0.65 +/- 0.29.
• Amanita augusta fruiting body: Zn 211.1 +/- 0.86; Cu 218.6 +/- 1.65; Mn 108 +/- 0.11; Fe 171.1 +/- 11.21; Cd 0.61 +/- 0.11; Pb 0.41 +/- 0.03.
• Boletus subvelutipes fruiting body: Zn 299 +/- 0.86; Cu 290 +/- 1.08; Mn 118.2 +/- 0.11; Fe 1411.1 +/- 18.6; Cd 0.71 +/- 0.21; Pb 0.46 +/- 0.05.
• For B. subvelutipes, the cap and stipe values were Cd 0.76 +/- 0.02 and 0.98 +/- 0.02, with Pb 0.36 +/- 0.05 and 0.48 +/- 0.05, respectively.

Methods (brief)

The study collected wild mushroom sporocarps and substrate samples, separated cap, stipe, and whole fruiting-body portions, and analyzed heavy metals on a dry-weight basis. The article is designed around bioaccumulation and partitioning rather than a market survey. It reports triplicate analytical means and SDs.

Implications

This source contributes dry-basis wild mushroom occurrence context for cadmium and lead, and broader trace-metal context for zinc, copper, manganese, and iron. Because two species are not ordinary edible mushrooms, only the Macrolepiota procera row is a clean food-occurrence candidate. The other species should stay as context or be routed only where wild-mushroom bioaccumulation evidence is allowed.

Verification notes

• DOI, title, authors, journal, and year were taken from the PDF.
• Macrolepiota procera is the edible food-relevant row. Amanita augusta and Boletus subvelutipes values are retained for source completeness but should not be silently treated as retail edible mushroom occurrence.
• Values are dry weight and must not be pooled with fresh mushrooms without conversion.
