Algal cellulose, production and potential use in plastics: Challenges and opportunities

Christian Ludwig, Horst Pick, Enio Daniel Zanchetta, Tobias Borgmeyer, Adrian Pulgarin

The development of new biodegradable plastic materials from renewable sources is a major challenge for plastic industries to provide sustainable alternatives to petroleum plastic. Bio-based plastics are generally obtained from photosynthetic biomass such a ...

Quantification and characterization of microplastics input from runoff water in Kamo and Takano Rivers, Kyoto, Japan.

Microplastic particles can be found everywhere in the world and sources, transport processes and impact on the environment and human health is yet to be well understood. The goal of this work is to quantify and characterize the impact of non-point source m ...

Effects of Anthropogenic Discharge and Hydraulic Deposition on the Distribution and Accumulation of Microplastics in Surface Sediments of a Typical Seagoing River: The Haihe River

Florian Frédéric Vincent Breider, Yang Liu, Wenxin Liu

Microplastics pollution in river systems has generated great concern; however, few studies have focused on the contributions of multiple influencing factors to microplastics in river systems. In the current study, we utilized data on microplastics in surfa ...

Bioavailability of steroid hormones sorbed on microplastics for aquatic organisms through biological fluids

Florian Frédéric Vincent Breider, Thibault Béranger Masset, Cécilia Laetitia Carla Siri, Yang Liu

Many studies have reported that hydrophobic organic contaminants have the ability to sorb on microplastics in aquatic ecosystem via different mechanisms of sorption. However, a lack of studies investigating desorption of such contaminants in organism fluid ...

Microstructured biodegradable fibers for advanced controlled release

Shahrzad Shadman Yazdi

Biodegradable polymers are increasingly at the heart of therapeutic devices. Particularly in the form of thin and elongated fibers, they offer an effective strategy for controlled-release in a variety of biomedical configurations such as sutures, scaffolds ...

Recycling Plastic and Marine Debris: What Can Be Done about Bottle Caps?

When will the weight of all fish in the ocean equal the weight of plastic discards in the ocean? These plastic discards in the water impacts birds and sea life around the world. Just as the canary in the coal mine forewarns of danger, the Laysan or Pacific ...

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 ...

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 ...

Elevated Concentrations of 4-Bromobiphenyl and 1,3,5-Tribromobenzene Found in Deep Water of Lake Geneva Based on GCxGC-ENCI-TOFMS and GCxGC-mu ECD

Jeremy Samuel Arey, Saer Samanipour, Petros Dimitriou Christidis, Deedar Nabi

We quantified the concentrations of two little-studied brominated pollutants, 1,3,5-tribromobenzene (TBB) and 4-bromobiphenyl (4BBP), in the deep water column and sediments of Lake Geneva. We found aqueous concentrations of 625 +/- 68 pg L-1 for TBB and 66 ...
