First metal and metalloid study assessment for the Black Triggerfish Melichthys niger (Bloch, 1786): Baseline data from a pristine South Atlantic oceanic island

First assessment of Rare Earth Element organotropism in Solea solea in a coastal area: The West Gironde Mud Patch (France)

“…Electronic copy available at: https://ssrn.com/abstract=4496278 P r e p r i n t n o t p e e r r e v i e w e d benthic species, attributed to the greater proximity of the latter to sediments containing relatively high REEs due to their mineral content (Mayfield and Fairbrother, 2015;Wang et al, 2019). Given that Solea solea is a benthic fish mainly feeding on benthic macrofauna (Lagardère, 1987), this may explain higher concentrations in organs of Solea solea from the WGMP than in those of black triggerfish (Melichthys niger; Hauser-Davis et al, 2023).…”

“…The general scarcity of published data on REEs in fish organs (e.g. liver, kidneys, gills) and the disparity of organs and elements targeted in these pioneer studies (MacMillan et al, 2017;Squadrone et al, 2020;Souza et al, 2021;Lortholarie et al, 2021;Squadrone et al, 2022;Hauser-Davis et al, 2023), limit the comparison of REEs in these organs between different species and geographical regions, clearly suggesting the need for more systematic monitoring of REEs in different fish species worldwide (Figure 6).…”

“…Ce anomaly in the gills of Solea solea, an organ that has been seldomly studied in fish (Hauser-Davis et al, 2023;Lortholarie et al, 2021;Souza et al, 2021). Hence, future work should aim to understand the mechanisms of REEs transfer and organ-specific accumulation through both, the transfer (i.e.…”

“…Pannetier et al, 2016). Given that liver is an organ responsible for the detoxification of metals (Hauser-Davis et al, 2023), this might explain higher concentrations of REEs in liver of Solea solea compared to the other target organs.…”
