Trace elements assessment in Cerastoderma glaucum from port areas in the Tunisi...
Ben Youssef-Dridi, Soumaya; Magalhães, Luísa; Soares, Amadeu M. V. M.; Pereira, Eduarda; Freitas, Rosa; Gargouri, LamiaIn the present study, the seasonal concentration of seven trace elements was investigated in sediment and the cockle Cerastoderma glaucum tissues from two port areas in the North-East and South of Tunisia comparing cockles non-parasitized (NP) and parasitized (P) with digenean parasites. Elements concentration in sediments analyzed in both sites revealed that Zinc (Zn), Chromium (Cr), and Lead (Pb) were the mos...
The influence of temperature on the impacts of caffeine in mussels: evaluating ...
Cunha, Marta; Petrillo, Vincenzo; Madeira, Madalena; He, Yide; Coppola, Francesca; Meucci, Valentina; De Marchi, Lucia; Soares, Amadeu M. V. M.In aquatic ecosystems, the presence of pharmaceuticals, particularly caffeine (CAF), has been linked to wastewater discharge, hospital waste, and the disposal of expired pharmaceutical products containing CAF. Additionally, rising temperatures due to climate change are anticipated in aquatic environments. This study aimed to assess the toxicity of various CAF concentrations under current (17 °C) and projected (...
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...
Ecotoxicological impacts of metals in single and co-exposure on mussels: compar...
Morais, Tiago; Moleiro, Pedro; Leite, Carla; Coppola, Francesca; Pinto, João; Henriques, Bruno; Soares, Amadeu M. V. M.; Pereira, Eduarda; Freitas, RosaUsed in high-tech and everyday products, mercury (Hg), cobalt (Co), and nickel (Ni) are known to be persistent and potentially toxic elements that pose a serious threat to the most vulnerable ecosystems. Despite being on the Priority Hazardous Substances List, existing studies have only assessed the individual toxicity of Co, Ni and Hg in aquatic organisms, with a focus on the latter, ignoring potential synergi...
Ecotoxicological effects of fluvial eroded bitumen sediments from the Alberta o...
Cardoso, Diogo N.; Gonçalves, Sandra F.; Silva, Ana Rita R.; Soares, Amadeu M. V. M.; Wrona, Frederick J.; Loureiro, SusanaTo fully understand the ecological and cumulative effects of mining activities on the surrounding aquatic systems of the Canadian oil sands region, it is essential to understand the consequences of exposure to bitumen-containing soils/sediment from natural geomorphological processes. Both physical and chemical stress on aquatic biota can potentially result from exposure to natural bitumen, resulting from hillsl...
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...
Impact of Sea Warming and 17-α-Ethinylestradiol Exposure on the Lipid Metabolis...
Rodrigues, João A.; Bispo, Daniela S. C.; Silva, Mónica G.; Araújo, Rita; Soares, Amadeu M. V. M.; Freitas, Rosa; Gil, Ana M.This paper reports on an NMR metabolomics study of lipophilic extracts of Ruditapes philippinarum clams exposed to the hormonal contaminant 17-α-ethinylestradiol (EE2), at 17 °C and 21 °C. The results reveal that exposure at 17 °C triggers a weak response at low EE2 concentrations, suggestive of a slight increase in membrane rigidity, followed by lipid metabolic stability at higher EE2 concentrations. On the ot...
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...
The use of muscle biomarkers for assessing physiological effects of heavy metal...
Quina, Ana Sofia; Rodrigues, Andreia C. M.; Soares, Amadeu M. V. M.; da Luz Mathias, Maria; Gravato, CarlosThe greater white-toothed shrew Crocidura russula has been used as a sentinel species for estimating environmental risks to human populations. Previous studies in mining areas have focused on the liver of shrews as the primary target of physiological and metabolic changes due to heavy metal pollution. However, populations persist even when detoxification by the liver seems to be compromised and damage is observ...
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...
