Alatise et al. 2025 - metals in edible fruit nuts from Nigerian markets
Alatise, Aluko, and Okoye measured natural radionuclides and heavy metals in six edible fruit-nut categories from Lagos and Ogun State markets. The source is routeable to nuts and seeds because it reports market-sourced edible nut matrices and includes Pb, Cd, Cr, Ni, As, and Hg in the analytical scope. The abstract emphasizes that Ni and Cr were the relatively higher metal findings while still within the authors’ acceptable-limit comparison.
Key numbers
- Matrices were peanuts, cashew nuts, walnuts, date nuts, tiger nuts, and kola nuts sourced from major Lagos and Ogun State markets.
- Heavy-metal analytes were Pb, Cd, Cr, Ni, Co, Cu, Zn, As, and Hg by atomic absorption spectrometry.
- The abstract reports Ni and Cr as relatively higher, especially in tiger nuts and kola nuts, while describing current contamination levels as not posing significant health risk.
- Radionuclide results are context only for HMI heavy-metal routing.
Methods (brief)
Gamma-ray spectrometry was used for radionuclides; atomic absorption spectrometry was used for heavy metals. The PDF describes market sampling in southwestern Nigeria.
Implications
Certification: broad nuts-and-seeds occurrence context, with cashew and peanut routeability. Courses: useful mixed radiological/heavy-metal monitoring example. App: supports Nigeria market context for nuts but needs table-level extraction before quantitative ranking.

Verification notes
The first-page abstract supplies the routeable matrices, analyte list, methods, and qualitative high-metal pattern. Full table extraction remains a follow-up for exact per-nut values.
