Shukla and Kumar 2020 - heavy metals in Prayagraj honey
Shukla and Kumar analyzed pollen origin, physicochemical parameters, minerals, and heavy metals in 14 honey samples from Prayagraj District, Uttar Pradesh. Most Cd, Pb, Cu, and As measurements were below 0.01 mg/kg, with a few detectable Cd and Pb values. The source is honey occurrence evidence and does not support the mineral-water row implied by the fetched filename.
Key numbers
The abstract reports heavy metals in mg/kg. Cd, Pb, Cu, and As were below the detection limit of <0.01 mg/kg in all samples except:
| Sample | Detectable values |
|---|---|
| H6 | Cd 0.01 mg/kg; Pb 0.27 mg/kg |
| H11 | Cd 0.02 mg/kg; Pb 0.05 mg/kg |
| H13 | Pb 0.02 mg/kg |
| H14 | Cd 0.01 mg/kg; Pb 0.04 mg/kg |
The abstract text uses “Pd” where the context and heavy-metal list indicate Pb; this page records the value as lead but flags the typographic issue for audit.
Methods (brief)
The study combined melissopalynology with physicochemical analysis. Heavy metals were reported alongside minerals and honey-quality parameters. The extracted text reports values and detection-limit language but does not expose the full instrumental-method detail for the heavy-metal assay.
Implications
Certification: Useful as India-specific honey occurrence evidence for Pb and Cd with mostly non-detect findings.
Courses: Demonstrates how honey-origin papers may carry usable contaminant data alongside pollen and quality measures.
App: Supports a regional honey evidence point after synthesis.

Verification notes
The PDF abstract appears to print “Pd” in the exception list despite introducing cadmium, lead, copper, and arsenic; because palladium is not otherwise part of the described heavy-metal panel, the values are treated as Pb with this discrepancy preserved for audit.
