Biochemical alterations caused by lanthanum and gadolinium in Mytilus galloprovincialis after exposure and recovery periods

An alien metabolite vs. a synthetic chemical hazard: An ecotoxicological comparison in the Mediterranean blue mussel

“…Accordingly, Teixeira et al (2017) proposed that increased J o u r n a l P r e -p r o o f protein content in mussels exposed to the antihistamine cetirizine was possibly associated with the induction of defensive mechanisms. Furthermore, increased GLY content was observed in FFB-treated mussels, suggesting that GLY was not the preferential energy reserve used to fuel up the defense mechanisms of mussels that probably stored energy to fight the stressors (Cunha et al, 2022). In addition, NMR metabolic profiles revealed high levels of homarine, a crucial osmolyte in marine bivalves (Jones et al, 2008), in FFBtreated mussels, as also occurred in M. galloprovincialis exposed to cadmium (Wu et al, 2017).…”

Removal of chromium(III) from contaminated waters using cobalt ferrite: how safe is remediated water to aquatic wildlife?

“…In what regards to detoxification capacity, the results obtained demonstrated that CbEs were not involved in Cr elimination, with similar activity in CTL and Cr-exposed mussels. CbEs are commonly involved in pesticides detoxification in bivalves (Antognelli et al 2006 ; Iummato et al 2018 ), butand the study conducted by Cunha et al ( 2022 ) also demonstrated the lack of activation in the presence of the rare earth element Lanthanum (La). Nevertheless, Chaâbane et al ( 2020 ) demonstrated the induction of phase II detoxification enzymes GSTs, in Venus verrucosa exposed to 10 and 100 μg/L of Cr(VI), which may indicate higher toxicity of Cr hexavalent form in comparison to trivalent one (Zhou et al 2017 ).…”

Determination of the distribution of rare earth elements La and Gd in Daphnia magna via micro and nano-SXRF imaging

“…Many studies on freshwater and marine organisms have demonstrated that Gd affects the antioxidant defences of cells and therefore causes oxidant stress. 40 Cunha et al 41 showed in experiments with Mytilus galloprovincialis a higher accumulation of La compared to Gd, but a stronger effect of Gd on biochemical pathways during short-term exposure.…”
