Abstract

More than 80% of the pollution present in ocean comes from land and human activities carried out there. Coastal waters, containing a large part of marine biodiversity, are directly impacted by these anthropogenic pressures. More especially, port areas, which constitute living place to numerous marine species, are subject to additional risks of pollution specific to port activities (maritime traffic, chronic pollution by hydrocarbons or antifouling paints, etc.). Monitoring contamination in these port areas is an important issue, especially in Corsica where the coastal population can double in summer season, considerably increasing the risks of pollution. The QUAMPO project, set up in the context of achieving of maintaining the good ecological status proposed by the Marine Strategy Framework Directive (MSFD), aims to assess the quality of water in the North Corsica ports. To do so, the use of a multibiomarker approach was carried out on two different marine mollusks: the Mediterranean mussel Mytilus galloprovincialis and the limpet Patella sp. As part of the QUAMPO project, the present master thesis aims at providing the last data, of January 2022. Organisms were sampled in three ports areas (Calvi, Île Rousse and St-Florent) and a battery of biomarkers of exposure (traces elements, organic pollutants) and biomarkers of effect focusing oxidative stress, energetic metabolism, immunity, neurotoxicity, and energy stock was analyzed to evaluate the induced-effect of chronic pollution in those ports, to confirm or no the potential of limpet as a reliable bioindicators, but also used an integrative index: the integrative biomarker response (IBR) to communicate results to ports managers in a simpler way. As results, some limpet biomarkers well respond to the different pollutant present in ports. Even if trace of pollution could be observed in all port, from different nature or concentration, North Corsica ports present globally good quality waters. Finally, the IBR index appears to be a useful tool to summarise all biomarkers responses.

Abstract

Lipids represent the major players in marine organisms as the major constituents of biological membranes, with key roles in biological processes and acclimation to environmental changes. New research trends aim to contribute to improving knowledge on the role lipids in the biological matrix, understanding the impact of climate change in marine organisms, and developing new tools for chemophenotyping, traceability, and biomarkers of trophic chains in marine ecosystems, such that the nutritional value or prospective bioactive compounds can be disclosed for health applications. “Lipids in the Ocean 2021” (http://lipids2021.web.ua.pt) was originally planned to be held at the University of Aveiro and ran from 5 to 7 July 2021 (and was ultimately an online conference due to uncertainties regarding the COVID-19 situation). The aim was to go in deep into research interests covering topics related to lipids from marine organisms, such as marine lipidomics, lipids as biomarkers in trophic webs, green lipids from the ocean (seaweeds, microalgae, and macrophytes), marine lipid biotechnology, and seafood traceability using lipids—from basic research to sustainable production and applications in the food, nutraceutics, feed, cosmetics, and pharma industries. This Special Issue welcomed not only attendees of “Lipids in the Ocean 2021” to publish their latest research outcomes but also all researchers in relevant fields to share their exciting works with the community.
