Contaminant Pathways in Marine Environment

The work of this research team is focused on contaminants, including the assessment of concentrations in various matrixes, fluxes, accumulation in marine organisms, partitioning at organs and tissues of key organisms, and responses at the biochemical level. The main research challenge of the group is to evaluate changes in the marine biogeochemical processes induced during the Anthropocene.

Focus on this vision we investigate the interaction of pollutants (classic and emergent) between water, sediments, and aquatic organisms coupled with the early-diagenetic processes. Within the emerging contaminants man-made molecules including pharmaceutics, new technologically relevant metals and plastics. A key question is understanding the combined effects of climate change stressors, ocean warming, acidification and marine heatwaves, on the bioaccumulation, elimination and ecotoxicological effects of contaminants. The impact of deep-sea mining, seen as an alternative source of metals to support green technologies, has an unknown impact on water chemistry and the organisms either by affecting the bioaccumulation or even changing the local biodiversity. The great concern about these issues is mirrored by the alert of international panels of experts. Our research is focused on contaminants measured in the field and on hyperbaric simulations performed in the laboratory.
From a different perspective, we investigate classical and emergent contaminants removal from contaminated water using graphene-based nanocomposites, natural bio-wastes, and algae-based biotechnologies. Better water quality, recovery of metabolic transformation, and effects of toxins naturally produced by marine phytoplankton species in harvest bivalves are currently being investigated. New tools for screening marine toxins as (bio)chemical sensors integrated into microfluidic systems are implemented. By multidisciplinary approach, cytotoxic assessment, genotoxic and epigenetic effects resulting from organisms’ exposure and cell lines to mixtures of classical and emergent contaminants are performed. The contaminant’s fate in estuarine and marine systems and the interactions with sediments are searched.
