“…Results of this study show different responses between abalone and the Pacific oyster Crassostrea gigas exposed to the same anode in a previous study (Levallois et al 2022). First, basal Al concentrations in oysters (20 mg kg −1 ) were lower than in abalones (33.7 mg kg −1 ) while basal Zn levels in oysters were 3 times higher (672 mg kg −1 ) than in abalones (195 mg kg −1 ).…”

“…Oysters were exposed for about three months to different Al concentrations obtained with an electrochemical experimental device simulating the dissolution of a galvanic anode. Total Al nominal concentrations were equal at the maximum to 300 µg/L, i.e., at concentrations approximately four times higher than in the present study and for a longer period [8]. After 84 days, phagocytic efficiency decreased by 40% and changes in the number or size of lysosomes were observed at this Al concentration, which may indicate a weakened immune system.…”

“…For that purpose, we chose a non-targeted metabolomic approach using ultra-high performance liquid chromatography coupled to high resolution mass spectrometry (UHPLC-HRMS). In accordance with the results of most recent works [7][8][9], the experimental study was carried out in a controlled environment to evaluate the comparative effects of Zn-and Al-Zn-Inanodes on oysters stabulated in tanks. The Pacific oyster, M. gigas, is commonly used for biomonitoring metal contamination because of its great economic interest.…”

Cathodic protection is widely used to protect metal structures from corrosion and is commonly applied on marine structures in seaports using sacrificial galvanic anodes. These anodes, either in Zinc, or preferen-tially nowadays in Al-Zn-In alloys, are expected to corrode instead of the metal to be protected. This leads to the release of specific dissolved species, Zn2+, Al3+, In3+ and solid phases like Al(OH)3. Few studies were conducted on the effects of anodes on marine organisms and concluded that further detailed investiga-tions are needed in controlled environments. We therefore propose an experimental approach to evaluate the effects of Zn and Al-Zn-In anodes on oysters stabulated in tanks, under conditions approaching those used in the ports. We chose a non-targeted metabolomic approach, using UHPLC coupled to HRMS, to study the effects on the entire metabolome, without any a priori. A modelling study of the chemical species, corresponding to the deg-radation products of the anodes, likely to be present near the exposed oysters, was also included. We identified 16 and 2 metabolites modulated by Zn- and Al-Zn-In-anodes respectively, involved in bi-ological functions, such as energy metabolism, osmoregulation, oxidative stress, lipid, nucleotide nucle-oside and amino acid metabolisms, defense and signaling pathways.

“…In addition, the anodes also contain incidental impurities, such as the eco-toxic elements cadmium and lead. Even though no acute toxicity of dissolved galvanic anodes was observed for bacteria (Bell et al, 2020), biological effects were observed for amphipods and oysters (Levallois et al, 2022). The interaction of multiple stressors, such as cadmium exposure and noise, has been shown to have an effect on lobsters (Stenton et al, 2022), making it even more challenging to predict the effects of small changes in concentrations of a contaminant in the marine environment.…”

There is a complex interaction between pollution, climate change, the environment and people. This complex interplay of actions and impacts is particularly relevant in coastal regions, where the land meets the sea. To achieve sustainable development in coastal systems, a better understanding is necessary of the role and impact of pollution and the connectedness of the elements, namely: pollution, climate and the people, as well as associated impacts unfolding in an integrated social-ecological system. In this context, the enabling capacity of tools connecting scientific efforts to societal demands is much debated. This paper establishes the basis for climate-smart socially innovative tools and approaches for marine pollution science. The goal of developing a set of innovative tools is twofold: first, to build on, integrate, and further improve the well-founded strengths in diagnosis and process understanding of systemic environmental problems; and, second, to provide decision-making with usable information to create actionable knowledge for managing the impact of marine pollution on the social-ecological system under a changing climate. The paper concludes by establishing the scope for a 'last mile' approach incorporating scientific evidence of pollution under climate change conditions into decision-making in a social-ecological system on the coast. The paper uses case studies to demonstrate the need for collaborative tools to connect the science of coastal pollution and climate with decision-making on managing human activities in a social-ecological system. Impact StatementCoastal regions are relevant because of the physical complexity of land meeting the ocean. At the same time, coastal development is an important element of the ocean economy. In recognition of this aspect, the 2030 Agenda for Sustainable Development and its SDG #14 call for the following priority actions: reducing marine pollution, particularly from land-based sources, litter, hazardous substances, and nutrients. To achieve sustainable development in coastal systems, a better understanding of the role and impact of pollution and the connectedness of the elements, namely pollution, climate and the people, as well as associated impacts unfolding in integrated social-ecological systems is necessary.
