Overview
Mohiuddin and colleagues analyzed edible mushroom varieties collected from different areas of Bangladesh for nutritional composition and heavy metals. The source is routeable for mushroom occurrence because it reports dry-weight concentration ranges and an average row for Fe, Cu, Zn, Mn, Cr, Pb, As, and Cd. Arsenic and cadmium were below the paper’s detection limit, while Pb ranged up to 0.59 ug/g dry weight and Cr was reported around 0.20-0.30 ug/g dry weight.
Key numbers
The paper reports heavy metals and minerals in ug/g dry weight except potassium, which is percent.
- Abstract-reported ranges: K 0.54-2.25%; Na 12.6-81.6 ug/g; Fe 69.5-626.2 ug/g; Cu 39.2-163.4 ug/g; Zn 30.1-75.5 ug/g; Mn 52.9-104.5 ug/g; Cr 0.20-0.30 ug/g; Pb 0.13-0.59 ug/g.
- Arsenic and cadmium were reported below detection at a stated detection limit of 0.01 ug/g.
- The table-average row reports Fe 253.37 ug/g, Cu 85.88 ug/g, Zn 43.24 ug/g, Mn 75.70 ug/g, Cr 0.25 ug/g, Pb 0.19 ug/g, and As and Cd below detection.
- The highest source-reported Pb value in the abstract range, 0.59 ug/g, is 0.59 mg/kg dry weight.
Methods (brief)
The authors collected edible mushroom varieties from Bangladesh and analyzed proximate composition plus mineral and heavy-metal content. Heavy metals were measured by atomic absorption spectrophotometry after sample preparation. The PDF prints summary ranges and a table of sample/group values; the routeable basis is dry weight.
Implications
This source contributes Bangladesh edible mushroom dry-basis occurrence data for Lead, Chromium, Cadmium, and Arsenic, Total. The source is especially useful for censored Cd and total As, because both are reported below 0.01 ug/g across the sampled set. It should not be pooled with fresh-basis mushroom results without moisture or basis conversion.

Verification notes
- The filename contains 2016, but the PDF citation and publication line show volume 1 issue 3, pages 495-501, 2015, with online publication dated 30 December 2015. The source page uses the PDF publication year and cite key year 2015.
- Arsenic is total arsenic in the heavy-metal table. No inorganic arsenic speciation is provided.
- Cd and As are censored at the paper’s stated detection limit of 0.01 ug/g.
- The table appears to provide sample/group entries rather than a retail-market probability sample, so downstream use should preserve the source’s Bangladesh collection-frame context.
