TL;DR: The present work proposes a definition of nanoplastics as particles unintentionally produced and presenting a colloidal behavior, within the size range from 1 to 1000 nm, based on the recently published and unpublished research definition.
Journal ArticleDOI
The toxicological interaction between ocean acidity and metals in coastal meiobenthic copepods.
TL;DR: It is indicated that copepods living in environments more prone to hypercapnia, such as mudflats where S. knabeni lives, may be less sensitive to future acidification, and ocean acidification is also expected to alter the toxicity of waterborne metals by influencing their speciation in seawater.
Journal ArticleDOI
Seasonal variation in consumption of benthic bacteria by meio- and macrofauna in an intertidal mudflat

TL;DR: Algal abundance was negatively correlated with bacterivory in both the nematode community and the foraminifer Ammonia tepida, suggesting that bacteria constitute an alternative resource that is consumed when algae are less abundant.
Journal ArticleDOI
Bacterivory in the common foraminifer Ammonia tepida: Isotope tracer experiment and the controlling factors
TL;DR: Grazing experiments were performed in order to measure effects of abiotic (temperature, salinity and irradiance) and biotic (bacterial and algal abundances) factors on uptake rates of bacteria and Ammonia seemed to be mainly dependant on algal resource.
Journal ArticleDOI
Nanoplastics on the coast exposed to the North Atlantic Gyre: Evidence and traceability

TL;DR: In this paper, the authors demonstrated the presence of nanoplastics in sand water extracts (SWEs) and investigated the potential of rare earth elements (REE) in tracing nanoplastic traces.
