Congrats to Mr. Jeric B. Gonzalez (College of Publication Affairs and Governance, RSU โ San Agustin Campus) on his collaborative research with international researchers!
Their study on rare earth elements (REE) in yellowfin tuna found the highest concentrations in the liver, followed by red muscle, and lowest in white muscle.
This scientific study offers a key baseline for monitoring marine pollution and supports better seafood safety guidelines for public health.
Thank you, Sir Jeric, for bringing honor to the university, the Marine Biology Department, and in advancing global marine science!

They investigated how rare earth elements (REE) build up inside yellowfin tuna and found that these elements donโt spread evenly, wherein its liver contains the highest level of REE concentration, followed by red muscle, and the white muscle contained the least.
This study provides a crucial baseline to monitor marine pollution and helps public health sector create better safety guidelines for seafood consumption.
Thank you, Sir Jeric, for bringing honor to the university and making a meaningful impact on global marine science and public health.

This study assessed rare earth element (REE) accumulation in 20 yellowfin tuna collected from southern Taiwan. Concentrations of 15 REEs (Sc, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) were quantified in white muscle, red muscle, and liver tissues and are reported on a dry-weight (dw) basis. Tissue concentrations showed a clear distribution pattern, with the liver containing the highest total REE concentration (26.56 ฮผg kgโ1 dw), followed by red muscle (20.97 ฮผg kgโ1 dw) and white muscle (13.41 ฮผg kgโ1 dw). Light REEs dominated the total burden, accounting for 94.5% of total REEs, and liver tissue showed a pronounced cerium enrichment with a Ce/La ratio of 10.69. Human exposure was evaluated using the Health Risk Index (HRI), defined as the ratio of estimated daily intake (EDI) to the corresponding reference dose (RfD); HRI values >1.0 were interpreted as indicating potential non-carcinogenic concern in the screening assessment. Under the modeled scenarios, occasional and average consumers remained below this threshold, whereas the cumulative HRI reached 1.39 for high-frequency consumers, and increased further when liver consumption was included. These findings provide baseline information on tissue-specific REE distribution in yellowfin tuna and indicate that exposure interpretation depends on both consumption frequency and the tissues consumed.
