Journal ArticleDOI
Oyster reproduction is affected by exposure to polystyrene microplastics
Rossana Sussarellu,Marc Suquet,Yoann Thomas,Christophe Lambert,Caroline Fabioux,Marie Eve Julie Pernet,Nelly Le Goïc,Virgile Quillien,Christian Mingant,Yanouk Epelboin,Charlotte Corporeau,J. Guyomarch,Johan Robbens,Ika Paul-Pont,Philippe Soudant,Arnaud Huvet +15 more
TL;DR: Evidence is provided that micro-PS cause feeding modifications and reproductive disruption in oysters, with significant impacts on offspring, providing ground-breaking data on microplastic impacts in an invertebrate model, helping to predict ecological impact in marine ecosystems.
Journal ArticleDOI
Exposure of marine mussels Mytilus spp. to polystyrene microplastics: Toxicity and influence on fluoranthene bioaccumulation.
Ika Paul-Pont,Camille Lacroix,Carmen González Fernández,Hélène Hégaret,Christophe Lambert,Nelly Le Goïc,Laura Frère,Anne-Laure Cassone,Rossana Sussarellu,Caroline Fabioux,J. Guyomarch,Marina Albentosa,Arnaud Huvet,Philippe Soudant +13 more
TL;DR: Results suggest that under the experimental conditions of this study micro-PS led to direct toxic effects at tissue, cellular and molecular levels, and modulated fluoranthene kinetics and toxicity in marine mussels.
Journal ArticleDOI
Development of an innovative and "green" stir bar sorptive extraction-thermal desorption-gas chromatography-tandem mass spectrometry method for quantification of polycyclic aromatic hydrocarbons in marine biota.
TL;DR: A "green" analytical method enabling the accurate and simultaneous routine analysis of 21 polycyclic aromatic hydrocarbons in reduced quantities of marine biota samples using alkaline digestion combined with stir bar sorptive extraction-thermal desorption-gas chromatography-tandem mass spectrometry (SBSE-GC-MS/MS).
Journal ArticleDOI
Active and passive biomonitoring suggest metabolic adaptation in blue mussels (Mytilus spp.) chronically exposed to a moderate contamination in Brest harbor (France)
TL;DR: Mussels chronically exposed to contamination have set up metabolic adaptation, which may contribute to their survival in the moderately contaminated harbor of Brest, suggesting metabolic changes could, at least partially, offset the negative effects of contamination.
Journal ArticleDOI
A selection of reference genes and early-warning mRNA biomarkers for environmental monitoring using Mytilus spp. as sentinel species.
TL;DR: Results support the use of qPCR technology and mRNA levels as early-warning biomarkers in marine monitoring programs and highlight the difficulty to find stable reference genes in wild, non-model species.
