Response of Mytilus galloprovincialis to cosmetic chemicals, under climate chan...
Cuccaro, AlessiaMarine-coastal zones, crucial for providing vital goods and services, face increasing stress from anthropogenic pollution by UV-filters and climate change (CC)-related environmental factors (temperature, pH, salinity). These stressors’ coexistence could create associated ecological and ecotoxicological risks at different biological levels. The cumulative impacts of multiple concurrent stressors can alter the ph...
Can temperature rise change the impacts induced by e-waste on adults and sperm ...
Leite, Carla; Russo, Tania; Cuccaro, Alessia; Pinto, João; Polese, Gianluca; Soares, Amadeu M. V. M.; Pretti, Carlo; Pereira, Eduarda; Freitas, RosaNowadays, it is of utmost importance to consider climate change factors, such as ocean warming, since the risk of negative impacts derived from increased surface water temperature is predicted to be high to the biodiversity. The need for renewable energy technologies, to reduce greenhouse gas emissions, has led to the increasing use of rare earth elements (REEs). Dysprosium (Dy) is widely used in magnets, motor...
Micro(nano)plastics and plastic additives effects in marine annelids: a literat...
Pires, Adília; Cuccaro, Alessia; Sole, Montserrat; Freitas, RosaPlastic debris are dispersed in the marine environment and are consequently available to many organisms of different trophic levels, including sediment-dwelling organisms such as polychaetae. Plastic degradation generates micro (MPs) and nanoplastics (NPs) and as well as releases bounded plastic additives, increasing the ecotoxicological risk for marine organisms. Therefore, this review summarizes current knowl...
Ecotoxicological screening of UV-filters using a battery of marine bioassays
Vieira Sanches, Matilde; Oliva, Matteo; De Marchi, Lucia; Cuccaro, Alessia; Puppi, Dario; Chiellini, Federica; Freitas, Rosa; Pretti, CarloThe present study aimed to assess the toxicity of seven UV-filters: zinc oxide nanoparticles (nZnO, particle size <100 nm), titanium dioxide nanoparticles (nTiO2, primary particle size 21 nm), 2-ethylhexyl-4-methoxycinnamate (EHMC), 4-methylbenzylidene camphor (4-MBC), avobenzone (AVO), octocrylene (OCTO) and benzophenone-3 (BP-3) on three species: Aliivibrio fischeri (inhibition of bioluminescence), Phaeodacty...
Relationship between wild-caught organisms for bioassays and sampling areas: Wi...
Sanches, Matilde Vieira; Oliva, Matteo; Pires, Adília; De Marchi, Lucia; Cuccaro, Alessia; Freitas, Rosa; Baratti, Mariella; Pretti, CarloPrevious studies suggested the suitability of the brackish-water serpulid (Ficopomatus enigmaticus) to be used as model organism for both marine and brackish waters monitoring, by the performance of sperm toxicity and larval development assays. The present study focused on larval development after the exposure of two F. enigmaticus populations (Mediterranean and Atlantic, collected in Italy and Portugal, respec...
Does salinity variation increase synergistic effects of triclosan and carbon na...
De Marchi, Lucia; Freitas, Rosa; Oliva, Matteo; Cuccaro, Alessia; Manzini, Chiara; Tardelli, Federica; Andrade, Madalena; Costa, Marcelo; Leite, CarlaThe use of carbon nanotubes (CNTs) is rapidly increasing and several scientific studies have addressed their toxicological properties. However, only a very small number of publications have deal with the interaction between CNTs and other molecules. Triclosan (TCS) is an antibacterial agent used in personal care and household products. Commonly detected in aquatic ecosystems, there is a strong evidence that aqu...
Soluble esterases as biomarkers of neurotoxic compounds in the widespread serpu...
Casu, Valentina; Tardelli, Federica; De Marchi, Lucia; Monni, Gianfranca; Cuccaro, Alessia; Oliva, Matteo; Freitas, Rosa; Pretti, CarloThe characterization of soluble cholinesterases (ChEs) together with carboxylesterases (CEs) in Ficopomatus enigmaticus as suitable biomarkers of neurotoxicity was the main aim of this study. ChEs of F. enigmaticus were characterized considering enzymatic activity, substrate affinity (acetyl-, butyryl-, propionylthiocholine), kinetic parameters (Km and Vmax) and in vitro response to model inhibitors (eserine he...
