Marine transport of plastic fragments from dolly ropes used in demersal fisheries in the North Sea

Florence Marie Renée Cuttat

Dolly ropes (DR) are used in beamtrawling and other types of fishing to protect the nets from being ripped by the sea bottom. They constitute an important source of plastic pollution in the regions where this type of fishing prevails. The aim of this proje ...

Recherche de fragments de plastique dans les sédiments profonds du Léman

Luiz Felippe De Alencastro, Florian Faure

A growing number of studies focusing on microplastics (plastic particles smaller than 5 mm) show this issue affects all environmental matrices and compartments, and suspicions grow as to their toxicity. In this context, the Commission Internationale pour l ...

PUTTING CIRCULAR ECONOMY PRINCIPLES INTO PRACTICE

Circular economies produce virtually no waste, as materials are re-used and recycled continuously. It’s a dramatic shift from the current linear economy in which we take, make, consume and dispose – drawing regularly on natural resources to create products ...

LABORATORY EXPERIMENTS OF PULSED SUBAQEOUS SEDIMENT DENSITY FLOWS: INTERNAL STRATIFICATION AND LAYERING

Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez, Mariangela Sfouni-Grigoriadou

This paper reports on an experimental study which focuses on reproducing small scale sediment density flows in a laboratory flume. The observations are aimed at improving the parametrization of the relations that govern the transition between different pha ...

Toxicity assessment of pollutants sorbed on microplastics using various bioassays on two fish cell lines

Luiz Felippe De Alencastro, Florian Faure, Frédéric Sciacca

Microplastics are tiny plastic fragments resulted from runoff and weathering breakdown of larger plastics debris. They represent an emerging concern for marine ecosystems. Microplastics impacts on aquatic life are little studied. These small particles coul ...
