“…Higher GSH/GSSG values observed in clams under control conditions (17 and 22 • C) evidence the maintenance of the redox balance under these conditions, regardless of the temperature of exposure. It is well known that under non-stressful conditions organisms tend to have higher reduced glutathione (GSH) in comparison to oxidized glutathione (GSSG) content, with higher GSH/GSSG values at non-stressful conditions [20,21,75,80]. The results obtained indicate that the concentrations of Hg in remediated water were not high enough to induce significant alterations in clams compared to organisms in control conditions.…”

“…For the aforementioned, the present study aimed to assess the possible toxicity of seawater, previously contaminated with Hg and remediated by GO-PEI, using the clam species R. philippinarum under different temperature scenarios, to assess the effects of temperature rise on the impacts induced by remediated water. Previous studies already demonstrated that this clam species is a good bioindicator, being commonly used in field and laboratory studies to evaluate the effects derived from the exposure to different pollutants, including metals [38,43,75], drugs [76][77][78], or nanoparticles [79,80]. R. philippinarum specimens were exposed for 28 days, at different treatments, including clean seawater (control-CTL); remediate seawater; and seawater containing Hg (50 µg/L), GO-PEI (10 mg/L) or the mixture of both.…”

Marine organisms are frequently exposed to pollutants, including trace metals, derived from natural and anthropogenic activities. In order to prevent environmental pollution, different approaches have been applied to remove pollutants from waste water and avoid their discharge into aquatic systems. However, organisms in their natural aquatic environments are also exposed to physico-chemical changes derived from climate change-related factors, including temperature increase. According to recent studies, warming has a negative impact on marine wildlife, with known effects on organisms physiological and biochemical performance. Recently, a material based on graphene oxide (GO) functionalized with polyethyleneimine (PEI) proved to be effective in the remediation of mercury (Hg) contaminated water. Nevertheless, no information is available on the toxic impacts of such remediated water towards aquatic systems, neither under actual nor predicted temperature conditions. For this, the present study assessed the toxicity of seawater, previously contaminated with Hg and remediated by GO-PEI, using the clam species Ruditapes philippinarum exposed to actual and a predicted temperature conditions. The results obtained demonstrated that seawater contaminated with Hg and/or Hg+GO-PEI induced higher toxicity in clams exposed to 17 and 22 °C compared to organisms exposed to remediated seawater at the same temperatures. Moreover, similar histological and biochemical results were observed between organisms exposed to control and remediated seawater, independently of the temperatures (17 and 21 °C), highlighting the potential use of GO-PEI to remediate Hg from seawater without significant toxicity issues to the selected marine species.

“…they have high concentration factors (CFs), the species are sedentary, ubiquitous and easily identifiable (Krishnakumar et al, 2018;Reguera et al, 2018). Bivalves and gastropod molluscs have the ability to accumulate high concentrations of organic and inorganic pollutants, and the chemical analysis of tissues of organisms gives evidence of the trace metals bioavailability in seawater and sediments over time (Hervé-Fernández et al, 2010;Duarte et al, 2011;Gupta et al, 2014;Marques et al, 2018;Buzzi and Marcovecchio, 2018;Krupnova et al, 2018;Joksimovic et al, 2018). Filter feeders permanently accumulate metals in their tissues filtering the surrounding water (i.e.…”

In this study, we have investigated Cd, Cr, Cu, Ni, Pb and Zn in the biomonitors Mytilus chilensis and Nacella (P) magellanica sampled along seven selected sampling sites along km of the coastal area of the Beagle Channel (Tierra del Fuego, Argentina) in four sampling campaigns: 2005, 2007, 2011 and 2012. The control charts were built by applying Johnson's (Biometrika 36: 149-175, 1949) probabilistic method for the first time in this marine area. We determined the metal concentration overlap ranges in the selected biomonitors (as well as medians and distribution), and the overlap bioaccumulation index (OBI) with respect to the lowest (OBI-L1) and the highest (OBI-L) extreme values of the overlap metal concentration ranges. The OBI can be used as an integrative tool in the management of prevailing unpolluted/polluted marine coastal ecosystems. It consents to identify the most suitable organisms for managing several environmental conditions where an ecosystem quality control is needed. The OBI-L1 index can be employed as a preventive signal of alarm when the contamination process is in its early stages. For Cd, Cr, Cu, and Ni, Nacella showed high OBI-L values that suggest its use as a biomonitor for mainly polluted marine ecosystems, in particular for Cd. Mytilus showed high Cd values for the OBI-L1 which means that this species is highly sensitive to a very low variation of the Cd levels in seawater. Good OBI-L1 values were instead obtained for Mytilus for Cr and Cu, showing the good aptitude of these organisms to detect minimum variations of trace metals concentrations in seawater. The OBI index and its related guidelines have both theoretical and practical implications in environmental management. They can be used, for instance, in environmental prevention from events such as oil spills or other marine disasters. Marine ecosystems are complex systems. According to the Ashby's Law (1957, 1958), the understanding of a complex system (requisite variety) depends on the information variety owned by the observer. The OBI index enhances the observer's information variety about the performance of the molluscs as metal biomonitors in marine ecosystems. Eventually, here we propose to conceptualize the wide set of biomonitoring knowledge endowment as an open and evolutionary endowment of information variety supporting the environmental management.

“…Under laboratory conditions, Lin et al [71] found a significant increase in the LPO levels under high exposure of metals (Cu, Pb, and Cd) in the leaves of the seagrass Zostera japonica. Similarly, the pro-oxidant levels accompanied the enhanced accumulation of metal(loid)'s As and Pb in the digestive gland of the Manila clam Ruditapes philippinarum collected in a contaminated site in Tagus estuary [Portugal] [72]. The mussels Mytilus galloprovincialis exposed to seawater enriched with trace metals (Cu, Hg, and Cd) caused oxidative damage that was milder in the cases of Cu and Hg and more pronounced for Cd [73].…”

Transitional water systems (TWSs) may be threatened by various metals originating from increased agricultural, industrial activities, or urban effluents. Macroalgae are one of the biological quality elements used to monitor and assess the health status of TWS due to their structural and functional key role in marine ecosystems. Here, metal accumulation from the macroalgae Ulva laetevirens Areschoug (1854) and oxidative stress by lipid peroxidation (LPO) biomarker were investigated during four sampling seasons from three sampling sites (SMM: Santa Maria del Mare; PM: Porto Marghera; SG: San Giuliano) of Venice Lagoon, affected by different anthropogenic stressors. The metal pollution index (MPI) scores for U. laetevirens increased in the order SMM < PM < SG (sea inlet < industrial area < Osellino River estuary), with average values per site of 2.99, 4.37, and 6.33, respectively. The level of LPO was statistically correlated with the concentration of toxic metal(loid)s (As, Pb, Hg) measured in macroalgae, and seasonality affected both levels of LPO and metal bioaccumulation, with peak values during spring and summer. These findings highlighted the efficiency and usefulness of the oxidative stress test (LPO) on the common macroalga U. laetevirens as an early warning signal for health assessment in aquatic ecosystems.
