“…Recent research has been testing the use of nanomaterials for water remediation, including GO–PEI, with few studies showing the impacts of these materials on marine wildlife [ 1 , 33 , 34 , 35 , 102 , 103 ]. Previous studies [ 1 , 33 ] have already demonstrated that at the control temperature (17 °C), GO–PEI (10 mg/L) induced biochemical impacts (metabolism and oxidative status alterations) in mussels and clams, with greater impacts in mussels.…”

“…In the last decade, different methodologies, such as ultrafiltration, reverse osmosis and electrochemical methods, have been developed to remediate polluted waters before being discharged into coastal systems [ 1 , 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. Nevertheless, these methodologies are frequently low-cost but inefficient, or efficient but expensive [ 36 , 37 , 38 , 39 ].…”

The Influence of Temperature Increase on the Toxicity of Mercury Remediated Seawater Using the Nanomaterial Graphene Oxide on the Mussel Mytilus galloprovincialis

Mercury (Hg) has been increasing in waters, sediments, soils and air, as a result of natural events and anthropogenic activities. In aquatic environments, especially marine systems (estuaries and lagoons), Hg is easily bioavailable and accumulated by aquatic wildlife, namely bivalves, due to their lifestyle characteristics (sedentary and filter-feeding behavior). In recent years, different approaches have been developed with the objective of removing metal(loid)s from the water, including the employment of nanomaterials. However, coastal systems and marine organisms are not exclusively challenged by pollutants but also by climate changes such as progressive temperature increment. Therefore, the present study aimed to (i) evaluate the toxicity of remediated seawater, previously contaminated by Hg (50 mg/L) and decontaminated by the use of graphene-based nanomaterials (graphene oxide (GO) functionalized with polyethyleneimine, 10 mg/L), towards the mussel Mytilus galloprovincialis; (ii) assess the influence of temperature on the toxicity of decontaminated seawater. For this, alterations observed in mussels’ metabolic capacity, oxidative and neurotoxic status, as well as histopathological injuries in gills and digestive tubules were measured. This study demonstrated that mussels exposed to Hg contaminated seawater presented higher impacts than organisms under remediated seawater. When comparing the impacts at 21 °C (present study) and 17 °C (previously published data), organisms exposed to remediated seawater at a higher temperature presented higher injuries than organisms at 17 °C. These results indicate that predicted warming conditions may negatively affect effective remediation processes, with the increasing of temperature being responsible for changes in organisms’ sensitivity to pollutants or increasing pollutants toxicity.

“…Adsorption is a mechanism broadly used both in traditional remediation approaches and nanoremediation for treating contaminated seawater. For instance, since 2013, the adsorbent capacity of functionalized ferrite NPs has been investigated for Pb and Hg removal from seawater [72,95]. Nowadays, the latest advancement in the application of ferrite oxides for marine nanoremediation is focused on manganese-ferrite NP as a good adsorbent material [96].…”

“…Nowadays, the latest advancement in the application of ferrite oxides for marine nanoremediation is focused on manganese-ferrite NP as a good adsorbent material [96]. Recently, Coppola and co-workers explored the use of manganese-ferrite NP (MnFe 2 O 4 -NPs, produced by the oxidative hydrolysis of ferrous sulfate heptahydrate and manganese sulfate in alkaline conditions) to remediate seawater from As and Pb [72,73]. Despite their efficiency for metal remediation in seawater, these ENMs have been demonstrated to negatively affect marine bivalve species (Mytilus galloprovincialis, Ruditapes philippinarum) causing a reduction of the metabolic activity and a gain of antioxidant defenses, neurotoxicity, and oxidative stress [71][72][73].…”

The Era of Nanomaterials: A Safe Solution or a Risk for Marine Environmental Pollution?

In recent years, the application of engineered nanomaterials (ENMs) in environmental remediation gained increasing attention. Due to their large surface area and high reactivity, ENMs offer the potential for the efficient removal of pollutants from environmental matrices with better performances compared to conventional techniques. However, their fate and safety upon environmental application, which can be associated with their release into the environment, are largely unknown. It is essential to develop systems that can predict ENM interactions with biological systems, their overall environmental and human health impact. Until now, Life-Cycle Assessment (LCA) tools have been employed to investigate ENMs potential environmental impact, from raw material production, design and to their final disposal. However, LCA studies focused on the environmental impact of the production phase lacking information on their environmental impact deriving from in situ employment. A recently developed eco-design framework aimed to fill this knowledge gap by using ecotoxicological tools that allow the assessment of potential hazards posed by ENMs to natural ecosystems and wildlife. In the present review, we illustrate the development of the eco-design framework and review the application of ecotoxicology as a valuable strategy to develop ecosafe ENMs for environmental remediation. Furthermore, we critically describe the currently available ENMs for marine environment remediation and discuss their pros and cons in safe environmental applications together with the need to balance benefits and risks promoting an environmentally safe nanoremediation (ecosafe) for the future.
