Pollution due to Plastics and Microplastics in Lake Geneva
AI summary Read the abstract
Lake Geneva was found to be contaminated with diverse microplastic particles including primary pellets and secondary fragments, with floating microplastics confirmed to adsorb polychlorinated biphenyls (PCBs). The study highlights both the widespread presence of microplastics in freshwater environments and the need for improved beach sampling methodologies.

Plastic pollution in Swiss surface waters: nature and concentrations, interaction with pollutants
AI summary Read the abstract
Researchers surveyed microplastic pollution in Swiss surface waters including multiple lakes and rivers. The study confirmed the presence of microplastics in Swiss freshwater environments and investigated interactions between microplastics and chemical pollutants, expanding the data on freshwater microplastic contamination beyond the initial findings from Lake Geneva.
Pollution due to plastics and microplastics in Lake Geneva and in the Mediterranean Sea
AI summary Read the abstract
Researchers synthesized available data on plastic and microplastic pollution in Lake Geneva and the Mediterranean Sea, finding that both systems are significantly contaminated and that lake environments have received far less scientific attention than marine systems. The study calls for standardized sampling protocols to enable meaningful comparisons between freshwater and marine microplastic contamination levels.
Plastics in Paradise: Quantifying Microplastics in Lake Champlain Beaches
AI summary Read the abstract
Researchers quantified and characterized microplastics on Lake Champlain beaches, finding contamination at all sampled sites with fragments and fibers as the dominant particle types. The study documents that even inland freshwater shorelines accumulate significant microplastic loads over time.
Recherche de fragments de plastique dans les sédiments profonds du Léman
AI summary Read the abstract
This exploratory study searched for microplastic fragments in deep sediment cores from Lake Geneva, finding plastic particles at multiple depths. The detection of plastics in deep lake sediments confirms that microplastic contamination has penetrated one of Europe's largest freshwater lakes throughout its entire water column.
Recherche de fragments de plastique dans les sédiments benthiques du Léman
AI summary Read the abstract
French researchers searched for plastic fragments in bottom sediments from twelve sites in Lake Geneva, finding plastic particles in every sample. Most particles were PET fragments from the breakdown of bags and coatings, demonstrating that even well-monitored inland lakes accumulate microplastic pollution in their sediments.
