Oktariani et al. 2023 - Heavy metals content in fresh tuna and swordfish caught from Hindian and Pacific Oceans: Health risk assessment of dietary exposure
This study measured Cd, Pb, and Hg in fresh yellowfin tuna and swordfish caught from Indian/Hindian and Pacific Ocean fishing zones and collected in Indonesia.
Key numbers
- The abstract reports that none of the sampled yellowfin tuna or swordfish exceeded Indonesian National Standard or European Commission Regulation No. 1881/2006 threshold levels for Cd, Pb, or Hg.
- The adult PTWI value for Pb in yellowfin tuna from the Indian Ocean was 0.0038 mg/kg, higher than the recommended standard cited by the authors.
- Target hazard quotient and total target hazard quotient values were within the acceptable range according to the authors.
Methods
Fish were obtained from fishermen’s catches in FAO Fishing Zone 57 and Zone 71, collected at Benoa Harbor and Bitung, and analyzed for Pb, Cd, and Hg by atomic absorption spectroscopy. The study also calculated EDI and THQ/TTHQ.
Implications
This source supports seafood context for Indonesian tuna and swordfish export/consumption safety, but the abstract-level extraction gives compliance/risk summaries more clearly than individual concentration means. Use the full tables before pooling numeric occurrence distributions.

Verification notes
- Source identity checked against DOI 10.14202/vetworld.2023.858-868 and the downloaded PDF.
- The title uses “Hindian” in the source; this appears to mean Indian Ocean, but the source title is preserved as published.
