“…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.

“…This corrosion process then leads to the formation of dissolved species, e.g., Zn 2+ , In 3+ , and Al 3+ , and solid phases, e.g., Al(OH) 3 , which are released in the seaport water. The need to assess the environmental impact of galvanic anodes was then expressed and a few studies were devoted to this problem [ 5 , 6 , 7 , 8 , 9 ]. Very recently, a study was set up over two years (2020 and 2021) to observe whether Al-Zn-In-sacrificial anodes had an impact on the health status of the black scallop Mimachlamys varia in a port environment (commercial port and marina of La Rochelle, France), using a multi-biomarker approach [ 7 , 10 ].…”

Cathodic protection is widely used to protect metal structures from corrosion in marine environments using sacrificial galvanic anodes. These anodes, either in Zinc, or preferentially nowadays in Al-Zn-In alloys, are expected to corrode instead of the metal structures. This leads to the release of dissolved species, Zn2+, Al3+, and In3+, and solid phases such as Al(OH)3. Few studies have been conducted on their effects on marine organisms, and they concluded that further investigations are needed. We therefore evaluated the effects of Zn and Al-Zn-In anodes on oysters stabulated in tanks, under controlled conditions defined through a comparison with those prevailing in a given commercial seaport used as reference. We analyzed the entire metabolome of gills with a non-targeted metabolomic approach HRMS. A modelling study of the chemical species, corresponding to the degradation products of the anodes, likely to be present near the exposed oysters, was also included. We identified 16 and two metabolites modulated by Zn- and Al-Zn-In-anodes, respectively, that were involved in energy metabolism, osmoregulation, oxidative stress, lipid, nucleotide nucleoside and amino acid metabolisms, defense and signaling pathways. The combination of chemical modelling and metabolomic approach, used here for the first time, enlightened the influence of Zn present in the Al-Zn-In anodes.

Al-Bi-Ga alloy is a good sacrificial anode material, but research on its electrochemical performance in seawater, freshwater, and soil is limited. This article focuses on Al-Bi-Ga-Pb-In and Al-Bi-Ga-Sn-In alloys. The working potential, current efficiency, and corrosion morphology of aluminum alloys under constant current conditions were studied through electrochemical performance testing, microstructure observation, and composition detection. The influence of alloy elements (Bi, Ga, Pb) on the electrochemical performance of aluminum alloys was analyzed. The results indicate that the dissolution morphology of Al-Bi-Ga-Sn-In is better than that of Al-Bi-Ga-Pb-In, and the distribution of Bi element in Al-Bi-Ga-Sn-In is more extensive. The destruction of the oxide film on the surface of aluminum alloy is more uniform, exhibiting better dissolution morphology; As the Bi content increases, the corrosion rate shows a trend of first increasing, then decreasing, and then increasing. The current efficiency first decreases and then increases, usually stopping and rebounding around 4.5%; Ga can increase the corrosion rate and reduce the surface impedance value; When the Ga content is greater than 0.10%, the corrosion rate significantly increases; As the Ga content increases, the current efficiency first decreases and then increases, then stops decreasing and rebounds around 0.2%.
