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...
Toxicity evaluation of carboxylated carbon nanotubes to the reef-forming tubewo...
De Marchi, Lucia; Oliva, Matteo; Freitas, Rosa; Neto, Victor; Figueira, Etelvina; Chiellini, Federica; Morelli, Andrea; Soares, Amadeu M. V. M.In recent years, oxidative stress has been recognized as one of the most common effects of nanoparticles in different organisms. Ficopomatus enigmaticus (Fauvel, 1923), a member of a large family of serpulidae polychates, is an important encrusting organism in a diverse set of marine habitats, from harbours to coral reefs. This species has been previously studied for ecotoxicological purposes, despite the lack ...
The impacts of warming on the toxicity of carbon nanoparticles in mussels
Andrade, Madalena; De Marchi, Lucia; Pretti, Carlo; Chiellini, Federica; Morelli, Andrea; Figueira, Etelvina; Rocha, Rui J. M.; Soares, Amadeu M. V. M.With the increased production and research on nanoparticles, the presence of carbon nanotubes (CNTs) in aquatic systems is very likely to increase. Although it has been shown that CNTs may cause toxicity in marine organisms, to our knowledge, the possible impacts under global temperature increase is still unknown. For this reason, biochemical and physiological impacts induced in Mytilus galloprovincialis due to...
The influence of simulated global ocean acidification on the toxic effects of c...
De Marchi, Lucia; Pretti, Carlo; Chiellini, Federica; Morelli, Andrea; Neto, Victor; Soares, Amadeu M. V. M.; Figueira, Etelvina; Freitas, RosaOcean acidification events are recognized as important drivers of change in biological systems. Particularly, the impacts of acidification are more severe in estuarine systems than in surface ocean due to their shallowness, low buffering capacity, low salinity and high organic matter from land drainage. Moreover, because they are transitional areas, estuaries can be seriously impacted by a vast number of anthro...
The influence of Climate Change on the fate and behavior of different carbon na...
De Marchi, Lucia; Neto, Victor; Pretti, Carlo; Chiellini, Federica; Morelli, Andrea; Soares, Amadeu M. V. M.; Figueira, Etelvina; Freitas, RosaThe widespread use of Carbon nanotubes (CNTs) has been increasing exponentially, leading to a significant potential release into the environment. Nevertheless, the toxic effects of CNTs in natural aquatic systems are related to their ability to interact with abiotic compounds. Considering that salinity variations are one of the main challenges in the environment and thus may influence the behavior and toxicity ...

De Marchi, Lucia; Pretti, Carlo; Chiellini, Federica; Morelli, Andrea; Neto, Victor; Soares, Amadeu M. V. M.; Figueira, Etelvina; Freitas, RosaAlthough the increased production of nanoparticles (NPs) has raised extensive concerns about the potential toxic effects on aquatic organisms, as well as the increasing evidences which documented the impact of ocean acidification (OA) on the physiology and fitness of marine invertebrates, limited number of studies reported their combined toxic effects. For these reasons, in the present study, we investigated th...

Toxic effects multi-walled carbon nanotubes on bivalves: comparison between of ...
De Marchi, Lucia; Neto, Victor; Pretti, Carlo; Figueira, Etelvina; Chiellini, Federica; Morelli, Andrea; Soares, Amadeu M. V. M.; Freitas, RosaDespite of the large array of available carbon nanotube (CNT) configurations that allow different industrial and scientific applications of these nanoparticles, their impacts on aquatic organisms, especially on invertebrate species, are still limited. To our knowledge, no information is available on how surface chemistry alteration (functionalization) of CNTs may impact the toxicity of these NPs to bivalve spec...
Effects of multi-walled carbon nanotube materials on Ruditapes philippinarum un...
De Marchi, Lucia; Neto, Victor; Pretti, Carlo; Figueira, Etelvina; Chiellini, Federica; Morelli, Andrea; Soares, Amadeu M. V. M.; Freitas, RosaThe toxicity of carbon nanotubes (CNTs) is closely related to their physico-chemical characteristics as well as the physico-chemical parameters of the media where CNTs are dispersed. In a climate change scenario, changes in seawater salinity are becoming a topic of concern particularly in estuarine and coastal areas. Nevertheless, to our knowledge no information is available on how salinity shifts may alter the...

De Marchi, Lucia; Neto, Victor; Pretti, Carlo; Figueira, Etelvina; Chiellini, Federica; Morelli, Andrea; Soares, Amadeu M. V. M.; Freitas, RosaSalinity shifts in estuarine and coastal areas are becoming a topic of concern and are one of the main factors influencing nanoparticles behaviour in the environment. For this reason, the impacts of multiwalled carbon nanotubes (MWCNTs) under different seawater salinity conditions were evaluated on the common ragworm Hediste diversicolor, a polychaete species widely used as bioindicator of estuarine environment...
