| contents | Contrasting accumulation of light and heavy rare earth elements in yellowfin tuna (Thunnus albacares): Tissue distribution and human exposure assessment. Gonzalez, Jeric B Wang, Ming-Huang Chen, Chih-Feng Chen, Chiu-Wen Dong, Cheng-Di Animals Tuna Metals, Rare Earth Water Pollutants, Chemical Humans Taiwan Environmental Monitoring Tissue Distribution Liver 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 μg kg dw), followed by red muscle (20.97 μg kg dw) and white muscle (13.41 μg kg 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. |
