Tkachuk et al. 2024 - ecological safety of sunflower seeds under agricultural intensification
Tkachuk and coauthors measured heavy metals and other toxicants in soil and sunflower seeds under intensive agricultural technology. The source is routeable to sunflower seeds because it reports direct seed testing for Pb, Cd, Cu, Zn, nitrates, and related soil contaminants. It is production-system context, not a consumer-market basket.
Key numbers
- The study measured Pb, Cd, Cu, and Zn in sunflower seeds and compared them with maximum permissible concentration values.
- The abstract states that no exceedance of permissible levels of heavy metals or nitrates was found in sunflower seeds.
- The authors calculated accumulation coefficients and report that Cu and Zn were absorbed/accumulated more intensely, while Pb was least absorbed.
- The paper also measured soil mobile forms of Pb, Cd, Cu, Zn, Hg, Co, Mo, B, and radioactive caesium.
Methods (brief)
Atomic absorption spectrophotometric methods were used to determine toxic substances in soil and sunflower seeds, according to the PDF methods summary.
Implications
Certification: Ukraine production-system context for sunflower seeds. Courses: example of seed-vs-byproduct accumulation caveat. App: routeable context with full table extraction needed for quantitative use.

Verification notes
The DOI and citation year are from the PDF citation line. Numeric seed values require table extraction; the abstract provides exceedance and accumulation-direction findings.
