Ranjbar et al. 2025 - mineral-water safety monitoring in Arak City
Ranjbar and coauthors assessed radioactive isotopes and heavy metals in mineral water consumed in Arak City, Iran. The heavy-metal result is primarily non-detect context: the abstract states that lead and chromium were not present in the tested mineral-water samples. The paper is routeable as bottled/mineral-water occurrence evidence but should be treated as a non-detect surveillance source rather than a concentration distribution until tables are extracted.
Key numbers
- The study used random sampling to assess radioactive isotopes and heavy metals in mineral water consumed at Arak City, Iran.
- The abstract states that Pb and Cr were not present in the samples.
- Specific activities for Ra-226 were not detected; Th-232, K-40, and Cs-137 were below WHO thresholds. Radionuclide results are context only for HMI metal routing.
Methods (brief)
The paper combines gamma spectrometry/radiological assessment with heavy-metal monitoring and machine-learning models. Heavy-metal method details require table/methods extraction before pooling.
Implications
Certification: mineral-water non-detect context for Pb and Cr in Iran. Courses: example of separating radiological and heavy-metal evidence. App: supports product-specific water context, not a global bottled-water claim.

Verification notes
The abstract explicitly states Pb and Cr absence. Because numerical metal concentrations are not present in the abstract, treat as routeable non-detect/source documentation pending method-table extraction.
