“…REEs concentrations in organs of Solea solea from the WGMP have been compared to those reported in the existing literature (Figure 6). The observed REEs concentrations in organs of Solea solea were overall similar in magnitude to those reported in the existing literature (MacMillan et al, 2017;Lortholarie et al, 2021;Squadrone et al, 2022).…”

“…Despite large differences in concentration, the organotropism found by these authors is close to that we observed in Solea solea. Similarly, Squadrone et al (2022) reported ΣREEs concentrations in spotted dogfish (Scyliorhinus stellaris), a chondrichthyes benthic species, obtained from an aquatic park, as follows: liver (30 μg kg -1 WW) > muscle (15 μg kg -1 WW) > kidney (13 μg kg -1 WW). If the concentrations in liver and kidneys are in good agreement with our data, ΣREEs in muscle of spotted dogfish were clearly higher.…”

“…Although some recent studies have addressed the natural bioaccumulation of REEs in marine fishes (Li et al, 2016;Squadrone et al, 2019;Squadrone et al, 2020;Lortholarie et al, 2020), only few studies have investigated REEs distribution in different tissues (organotropism), and the age or sex effects on their bioaccumulation (Squadrone et al, 2020;Lortholarie et al, 2021;Squadrone et al, 2022). This constitutes a major gap, since organotropism provides key information for (i) the identification of transfer pathways, (ii) the understanding of detoxification at the individual scale, and (iii) the evaluation of potential health risks related to the consumption of specific tissues.…”

“…more HREEs are accumulated than LREEs, which is also influenced by the large amount of Y detected. Squadrone et al ( 2022 ) also found a greater presence of HREEs. In their study, the ∑HREEs/∑LREEs were of 7.20 and 36.3 in spotted dogfish blood and liver samples, respectively.…”

“…In another sense, the differences between tissues could be explained in terms of the function of each organ (excretion and detoxification), and the different metabolic functions of the trace elements, for which higher concentrations in the liver and kidney than in the muscle are generally reported (Squadrone et al, 2022 ). Although the presence of REEs in fish is little studied, our results indicated that they are indeed accumulated in very small amounts in the muscle, the same as metals like As, Cd, Hg and Pb.…”

Rare earth elements are essential for modern life, although they are also classified as emerging pollutants. Currently, fish studies on these elements are very limited in general, but, with regard to the Caspian Sea, there is no reference to them at all. For this reason, our objective was to determine the concentrations of these elements in the golden grey mullet (Chelon auratus) and to contrast its bioaccumulation patterns with those of arsenic, cadmium, mercury and lead. For that purpose, 20 fish were caught in the southern part of the Caspian Sea. Heavy rare earth element concentrations were higher than light ones and the terbium levels were very high, probably due to anthropogenic contamination. The intestine tissue gave the highest concentrations, which could be indicative of a very low gastrointestinal absorption. For both rare earth and trace elements, muscle was the tissue that accumulated the least, despite which, cadmium and lead levels in muscle were of concern.

Levels of Rare Earth Elements in Food and Human Dietary Exposure: A Review

Rare earth elements (REEs) are a group consisting of the following 17 metals: Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Pm, Sc, Sm, Tb, Tm, Y and Yb. In the current century, the number of applications of REEs has significantly increased. They are being used as components in high technology devices of great importance industrial/economic. However, information on the risk of human exposure to REEs, as well as the potential toxic effects of these elements is still limited. In general terms, dietary intake is the main route of exposure to metals for non-occupationally exposed individuals, which should be also expected for REEs. The current paper aimed at reviewing the studies -conducted over the world- that focused on determining the levels of REEs in foods, as well as the dietary intake of these elements. Most studies do not suggest potential health risk for consumers of freshwater and marine species of higher consumption, or derived from the intake of a number of vegetables, fruits, mushrooms, as well as other various foodstuffs (honey, tea, rice, etc.). The current estimated daily intake (EDI) of REEs does not seem to be of concern. However, considering the expected wide use of these elements in the next years, it seems to be clearly recommendable to assess periodically the potential health risk of the dietary exposure to REEs. This is already being done with well-known toxic elements such as As, Cd, Pb and Hg, among other potentially toxic metals.
