Assessing the impact of organic contaminants of emerging concern on key marine organisms, examines the effects of organic contaminants of emerging concern (CECs)—including pharmaceuticals, microplastics, and other pollutants—on marine organisms and ecosystems, with a particular focus on their interactions under climate change (CC). Originating from industrial, agricultural, and urban sources, CECs disrupt marine life and ecosystems, threaten biodiversity, and pose risks to food safety and human health through the consumption of fish and shellfish. These challenges posed by CECs may be intensified by CC-driven stressors, such as rising water temperatures, acidification, and increased organic matter runoff, particularly in vulnerable regions like the heavily populated Mediterranean. MED-BIO focuses on key organisms across marine trophic levels, from microorganisms and zooplankton to bivalves and fish. These sentinels are studied to evaluate bioaccumulation, toxicity, and ecosystem impacts. Special emphasis is placed on biochemical biomarkers as early warning indicators of physiological and environmental disruptions. This predictive value, using generalist and cost-effective methodologies, will be complemented by advanced analytical approaches, including metagenomics, metatranscriptomics, and single-cell metabolomics. Additionally, particular attention is given to microbial communities, their gene expression linked to pollution, and the dynamics of harmful algal blooms and biotoxins, as these are critical elements at the base of the marine trophic chain.

To achieve its goals, MED-BIO will complement field studies with controlled microcosm experiments to investigate how CC stressors may amplify the effects of selected CEC mixtures on marine biota. Human health impacts will be addressed by studying the bioaccumulation of CECs in commercially relevant marine species, such as shrimp and fish, and analyzing how cooking and digestion affect human exposure. The MED-BIO proposal aligns seamlessly with the One Health framework. This multidisciplinary initiative integrates chemistry, microbiology, ecotoxicology, and environmental modeling to provide a comprehensive understanding of the impacts of CECs and CC on marine ecosystems. The consequences affect both wildlife and humans, as they are closely interconnected in heavily populated regions with significant contributions from coastal industries.

MED-BIO will generate valuable data to guide policies aimed at mitigating contamination, preserving marine biodiversity, and improving the safety and sustainability of seafood. This research will ultimately contribute to achieving several Sustainable Development Goals outlined by the United Nations.

In line with the European Green Deal’s zero pollution ambition, ONE-BLUE addresses the challenges by developing innovative effect-based monitoring systems together with an integrated assessment by chemical analysis to assess the profiles, concentrations, fate, behaviour, distribution, bioaccumulation, and adverse effects, including impacts on biodiversity by the presence of contaminants of emerging concern (CECs) and the climate change on different marine some of the specific objectives are defined. To improve the current knowledge of the levels, profiles, fate, behaviour of CECs, including Antibiotic Resistance Genes ,in the different marine compartments and ecosystems through three case studies (Atlantic and Arctic oceans and the Mediterranean Sea), To provide an advanced understanding of possible interaction between climate change drivers and CECs in marine ecosystems with studies in controlled conditions in marine mesocosms with special attention on microbial biodiversity and biogeochemical implications. ONE-BLUE is organised in 6 work packages: WP1-Case studies & sampling campaigns; WP2-Mesocosm studies; WP3-New technologies for monitoring, modelling, and forecasting; WP4-Data collection, fusion; WP5-Policies implementation and dissemination; and WP6-Management.
