Journal ArticleDOI
Cellular responses of Pacific oyster (Crassostrea gigas) gametes exposed in vitro to polystyrene nanoparticles
Carmen González-Fernández,Kevin Tallec,Nelly Le Goïc,Christophe Lambert,Philippe Soudant,Arnaud Huvet,Marc Suquet,Mathieu Berchel,Ika Paul-Pont +8 more
TL;DR: The results demonstrate that the effects of NPs occur rapidly, are complex and are possibly associated with the cellular eco-corona, which could modify NPs behaviour and toxicity.
Journal ArticleDOI
Influence of husbandry practices on OsHV-1 associated mortality of Pacific oysters Crassostrea gigas
TL;DR: Differences in mortality among sites and growing heights are discussed in relation to OsHV-1 infection intensity and prevalence in oysters, and the environmental data recorded during the outbreak are discussed.
Journal ArticleDOI
Surface functionalization determines behavior of nanoplastic solutions in model aquatic environments.
Kevin Tallec,Océane Blard,Carmen González-Fernández,Guillaume Brotons,Mathieu Berchel,Philippe Soudant,Arnaud Huvet,Ika Paul-Pont +7 more
TL;DR: Analysis performed over several days demonstrated that nanoplastics formed evolving dynamic structures detected mainly with an increase of the homo-aggregation level, indicating that surface properties of given polymers/particles are expected to influence their fate in complex and dynamic aquatic environments.
Journal ArticleDOI
Spatial distribution of mortality in Pacific oysters Crassostrea gigas: reflection on mechanisms of OsHV-1 transmission.
TL;DR: The distribution of OsHV-1-associated mortalities was spatially clustered, highly variable and clearly dependent on the age of oysters and their position in the water column, as well as factors known to influence mechanism of disease transmission in aquatic environments.
Journal ArticleDOI
Polystyrene microbeads modulate the energy metabolism of the marine diatom Chaetoceros neogracile
Marta Seoane,Carmen González-Fernández,Philippe Soudant,Arnaud Huvet,Marta Esperanza,Ángeles Cid,Ika Paul-Pont +6 more
TL;DR: To unravel the cytotoxicity of 2.5 μg mL-1 unlabelled amino-modified polystyrene beads on the marine diatom Chaetoceros neogracile, the strong aggregation and the negative charge of the beads assayed in the culture medium seemed to minimize particle interaction with cells and potentially associated impacts.
