Lalotra et al. 2016 - Heavy metals in wild mushroom sporocarps from Jammu Province

This study measured Zn, Cu, Mn, Fe, Cd, and Pb in three wild macrofungi and their associated soils from Jammu Province, India. The edible species Macrolepiota procera had the lowest reported Pb value, while the poisonous Boletus subvelutipes had the highest Pb value among the three species. Because two of the three species are not edible, this source is most useful as wild-mushroom bioaccumulation context, with the edible M. procera values separated from non-edible/toxic species in interpretation.

Key numbers

All concentrations are reported as mg/kg dry matter.

• Cd range across the investigated mushrooms: 0.23 +/- 0.01 to 0.71 +/- 0.21 mg/kg.
• Pb range across the investigated mushrooms: 0.046 +/- 0.05 mg/kg in edible Macrolepiota procera to 0.46 +/- 0.05 mg/kg in poisonous Boletus subvelutipes.
• Zn range: 87.2 +/- 1.18 to 299.0 +/- 0.86 mg/kg.
• Cu range: 83.6 +/- 0.20 to 290.0 +/- 1.08 mg/kg.
• Mn range: 25.50 +/- 1.20 to 118.2 +/- 0.11 mg/kg.
• Fe range: 118.6 +/- 5.01 to 1411.6 +/- 18.60 mg/kg.

The paper reports element distribution differences between cap and stipe, including higher metal accumulation in some cap fractions, but the extracted text does not preserve the full table layout clearly enough for every cap/stipe cell to be transcribed without rechecking the PDF table image.

Methods (brief)

The study collected three wild mushroom species and associated soil samples from different forest areas in Jammu Province. Metals were measured using atomic absorption spectrophotometry and inductively coupled plasma atomic emission spectrometry. Results are reported as mg metal per kg dry matter.

Implications

Certification: Only the edible Macrolepiota procera values are directly food-occurrence relevant. The Amanita augusta and Boletus subvelutipes values are context for fungal bioaccumulation and should not enter an edible-mushroom benchmark pool unless governance explicitly admits non-edible wild species as context only.

Courses: Useful example for separating edible, non-edible, and poisonous species when interpreting wild-mushroom metal data.

App: Supports a general caution that wild mushrooms can accumulate Pb and Cd, but does not support species-agnostic consumer values without species and edible-status separation.

Verification notes

• The DOI, title, authors, publication, and year are printed in the PDF.
• The page does not treat total chromium as Cr(VI); chromium is not one of the primary routed metals for this source page because the candidate file was Cd/Pb-focused and the key extractable toxic values are Pb and Cd.
