“…However, interactions between stressors may be complex and difficult to predict, showing from additive, synergetic to antagonist effects. According to recent studies, oxidative stress was enhanced in bivalves exposed to Hg and As under warming conditions (Coppola et al, 2017;Coppola et al, 2018a;Freitas et al, 2017). On the other way, Nardi et al (2018) demonstrated that the effects induced by Cd in M. galloprovincialis were not altered by increased temperatures.…”

“…Such environmental changes, associated to climate modification, may contribute to alterations in seawater characteristics, namely in terms of salinity and temperature. This can further result into changes in organism s sensitivity towards pollutants but also into modification of pollutants properties and their associated toxicity (Attig et al, 2014;Byrne, 2012;Coppola et al, 2018a;Izagirre et al, 2014;Manciocco et al, 2014;Mazzoto et al, 2013). In fact, marine and in particular estuarine organisms are naturally and simultaneously exposed to multiple stressors, including the ones associated to water characteristics and pollutants presence, with growing evidences that combined stressors frequently interact and often amplify effects (Dijkstra et al, 2013).…”

Mussels, such as the marine bivalve Mytilus galloprovincialis are sentinels for marine pollution but they are also excellent bioindicators under laboratory conditions. For that, in this study we tested the modulation of biochemical responses under realistic concentrations of the toxic metal Lead (Pb) in water for 28 days under different conditions of salinity and temperature, including control condition (temperature 17±1.0 ºC and salinity 30±1.0) as well as those within the range expected to occur due to climate change predictions (±5 in salinity and +4ºC in temperature). A comprehensive set of biomarkers was applied to search on modulation of biochemical responses in terms of energy metabolism, energy reserves, oxidative stress and damage occurrence in lipids, proteins as well as neurotoxicity signs. The application of an integrative Principal Coordinates Ordination (PCO) tool was successful and demonstrated that Pb caused an increased in the detoxification activity mainly evidenced by glutathione Stransferases and that the salinities 25 and 35 were, even in un-exposed mussels, responsible for cell damage seen as increased levels of lipid peroxidation (at salinity 25) and oxidised proteins (at salinity 35).

“…In particular, transcriptomic and biochemical alterations have been observed in different bivalve species in response to temperature rise. M. galloprovincialis mussels showed an increase of antioxidant enzymes and metallothionein gene expression levels when exposed to heat stress (Banni et al, Coppola et al, 2017;2018a, 2018bFaggio et al, 2016;Freitas et al, 2018;Kristan et al, 2014;Sureda et al, 2011;Viarengo et al, 2007). Several studies have also demonstrated the ecological relevance of this species.…”

Intertidal mussel species are frequently exposed to changes of environmental parameters related to tidal regimes that include a multitude of stressors that they must avoid or tolerate by developing adaptive strategies. In particular, besides air exposure during low tides, intertidal mussels are also subjected to warming and, consequently, to higher risk of desiccation. However, scarce information is available regarding the responses of mussels to tidal regimes, particularly in the presence of other stressors such as increased temperature. Investigating the impacts of such combination of conditions will allow to understand the possible impacts that both factors interaction may generate to these intertidal organisms. To this end, the present study evaluated the impacts of different temperatures (18 °C and 21 °C) on Mytilus galloprovincialis when continuously submersed or exposed to a tidal regime for 14 days. Results showed that in mussels exposed to increased temperature under submersion conditions, the stress induced was enough to activate mussels' antioxidant defenses (namely glutathione peroxidase, GPx), preventing oxidative damage (lipid peroxidation, LPO; protein carbonylation, PC). In mussels exposed to tides at control temperature, metabolic capacity increased (electron transport system activity, ETS), and GPx was induced, despite resulting in increased LPO levels. Moreover, the combination of tides and temperature increase led to a significant decrease of lipid (LIP) content, activation of antioxidant defenses (superoxide dismutase, SOD; GPx) and increase of oxidized glutathione (GSSG), despite these mechanisms were not sufficient to prevent increased cellular damage. Therefore, the combination of increased temperature and air exposure induced higher oxidative stress in mussels. These findings indicate that increasing global warming could be more impacting to intertidal organisms compared to organisms continuously submersed. Furthermore, our results indicate that air exposure can act as a confounding factor when assessing the impacts of different stressors in organisms living in coastal systems.

“…after exposure of organisms to different concentrations of Gd. Due to their sedentary and filtration behavior, as well as their capacity to respond to environmental alterations, M. galloprovincialis mussels are widely used as bioindicators of a vast diversity of pollutants, including classical elements such as metals (among others, (Coppola et al, 2018;Maanan, 2007;Mejdoub et al, 2018;Regoli and Principato, 1995) and compounds considered of emerging concern including pharmaceuticals (Balbi et al, 2018;Maria et al, 2016), and nanoparticles (Andrade et al, 2018;Auguste et al, 2018;Taze et al, 2016).…”

Recently, anthropogenic enrichment of rare earth elements (REE) have been reported in natural environments, due to increasing use and discharges of hospital/industrial wastewaters. Gadolinium (Gd), which is mainly used as contrast agent for magnetic resonance imaging in medical exams, may reach concentrations in water up to two orders of magnitude larger than baseline levels. Nevertheless, in marine systems scarce information is available concerning the toxicity of REE towards inhabiting organisms. This study aimed to evaluate the biochemical impact of anthropogenic Gd in the Mediterranean mussel Mytilus galloprovincialis, which is a species of commercial interest and one of the most accepted pollution bioindicator. Organisms were exposed to different concentrations of Gd (0, 15, 30, 60, 120 µg/L) for 28 days. At the end of the experiments, biomarkers related to mussels' metabolic (electron transport system activity and energy reserves content), oxidative stress status (cellular damage and the activity of antioxidant and biotransformation enzymes) and neurotoxic effects (activity of the enzyme Acetylcholinesterase) were measured, as well as Gd bioconcentration in organisms. Results showed a high content of Gd (2.5±0.50 µg/g) in mussels exposed to the highest concentration, contrary to those at control condition and at 15 and 30 μg/L of Gd (levels below 0.38 µg/g). Although no mortality was observed during the experimental period, exposure to Gd strongly affected the biochemical performance of M. galloprovincialis, including the decrease on mussels' metabolism, induction of oxidative stress and neurotoxicity, particularly evidenced at intermediate concentrations. These results may indicate that up to certain stressful levels, although lowering their metabolism, organisms may be able to activate defense strategies to avoid cellular injuries which, on the other hand, may compromise mussels physiological performance such as growth and reproduction success. Nevertheless, our findings support that the widespread utilization of Gd may represent an environmental risk in the future.
