Exploring toxicological interactions in a changing sea: the case of the alkaloi...
Russo, Tania; Coppola, Francesca; Paris, Debora; De Marchi, Lucia; Meucci, Valentina; Motta, Andrea; Carbone, Marianna; Di Cosmo, AnnaThe bisindolic alkaloid caulerpin (CAU) is a bioactive compound isolated from green algae of the genus Caulerpa that are highly invasive in the Mediterranean Sea. On the other side, the purine alkaloid caffeine (CAF) is one of the most globally consumed psychoactive substances and a widespread anthropogenic water pollutant. Both compounds display a large panel of biological properties and are well known to accu...
Can temperature influence the impacts induced in Mytilus galloprovincialis by n...
Leite, Carla; Coppola, Francesca; Queirós, Vanessa; Russo, Tania; Polese, Gianluca; Pretti, Carlo; Pereira, Eduarda; Freitas, RosaClimate change-associated factors and pollutants, such as rare earth elements (REEs), have been identified as contributors to environmental changes. However, the toxicity resulting from the combination of these stressors has received little attention. Neodymium (Nd) is a REE that has been widely used, and this study aimed to evaluate the responses of Mytilus galloprovincialis to Nd exposure (10 µg/L), under act...
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...
Sub-lethal effects induced in Mytilus galloprovincialis after short-term exposu...
Paciello, Sofia; Russo, Tania; De Marchi, Lucia; Soares, Amadeu M. V. M.; Meucci, Valentina; Pretti, Carlo; He, Yide; Della Torre, Camila; Freitas, RosaSurfactants are among the most common PPCPs that reach coastal systems, being often used in large quantities in cleaning products such as detergents and soap powders. Sodium lauryl sulfate (SLS) is listed in this group of emerging contaminants. Previous studies have already demonstrated the presence of SLS in aquatic environments and the negative effects on organisms living there. However, with ocean acidificat...
An alien metabolite vs. a synthetic chemical hazard: an ecotoxicological compar...
Russo, Tania; Coppola, Francesca; Leite, Carla; Carbone, Marianna; Paris, Debora; Motta, Andrea; Di Cosmo, Anna; Soares, Amadeu M. V. M.; Mollo, ErnestoBioactive natural products from marine invasive species may dramatically impact native communities, while many synthetic pharmaceutical drugs are released into the marine environment and have long-lasting harmful effects on aquatic life. Sometimes, metabolites from alien species and synthetic compounds share similar mechanisms of action, suggesting comparable ecotoxicological impacts. This applies to the alkalo...
The role of temperature on the impact of remediated water towards marine organisms
Coppola, Francesca; Bessa, Ana; Henriques, Bruno; Russo, Tania; Soares, Amadeu M. V. M.; Figueira, Etelvina; Pereira, Eduarda; Marques, PaulaMarine organisms are frequently exposed to pollutants, including trace metals, derived from natural and anthropogenic activities. In order to prevent environmental pollution, di erent approaches have been applied to remove pollutants from waste water and avoid their discharge into aquatic systems. However, organisms in their natural aquatic environments are also exposed to physico-chemical changes derived from ...
Oxidative stress, metabolic and histopathological alterations in mussels expose...
Coppola, Francesca; Bessa, Ana; Henriques, Bruno; Russo, Tania; Soares, Amadeu M. V. M.; Figueira, Etelvina; Marques, Paula A. A. P.; Polese, GianlucaThe modern technology brought new engineering materials (e.g. nanostructured materials) with advantageous characteristics such as a high capacity to decontaminate water from pollutants (for example metal(loid)s). Among those innovative materials the synthesis of nanostructured materials (NSMs) based on graphene as graphene oxide (GO) functionalized with polyethyleneimine (GO-PEI) had a great success due to thei...
Ecotoxicological effects of lanthanum in Mytilus galloprovincialis: biochemical...
Pinto, João; Costa, Marcelo; Leite, Carla; Borges, Cláudia; Coppola, Francesca; Henriques, Bruno; Monteiro, Rui; Russo, Tania; Di Cosmo AnnaInappropriate processing and disposal of electronic waste contributes to the contamination of aquatic systems by various types of pollutants such as the rare-earth elements (REE) in which lanthanum (La) is included. Knowledge on the toxicity of these elements in marine organisms is still scarce when compared to other metals such as mercury (Hg) and arsenic (As). Therefore, this study aims to assess the toxicity...
Biochemical and histopathological impacts of rutile and anatase (TiO2 forms) in...
Leite, Carla; Coppola, Francesca; Monteiro, Rui; Russo, Tania; Polese, Gianluca; Lourenço, Mirtha A. O.; Ferreira, Paula; Soares, Amadeu M. V. MTitanium dioxide (TiO2) particles have been widely used in various industrial applications and consumer products. Due to their large production and use, they will eventually enter into aquatic environments. Once in the aquatic environment TiO2 particles may interact with the organisms and induce toxic effects. Since the most common crystallographic forms of TiO2 are rutile and anatase, the present study evaluat...
