Detection and Identification of Microplastic Particles with Nanocellulose Structures
– According to an April, 2020 VTT Technical Research Centre of Finland news release  “… A method developed at VTT utilises nanocellulose structures for early particle identification. Nanocellulose would allow particles to be captured even before they enter waterways. The properties of nanocellulose films and hydrogels support the identification and capture of very small microplastic particles … The next step could be to develop new and inexpensive filtration solutions utilising the method … we could develop filtration methods for any industry where there is a risk of microplastics being generated and released into waterways …” #MicroPlastic NanoPlastic #PlasticWaste

Microplastic Particle Levels in Lake Erie Estimated
– On April 24, 2020, researchers with the Rochester Institute of Technology (RIT) reported “… the first three-dimensional mass estimate to show where microplastic pollution is collecting in Lake Erie. The study examines nine different types of polymers that are believed to account for 75 percent of the world’s plastic waste …”  “… Plastic behaves differently in lakes than in oceans … While massive floating ‘islands’ of accumulated plastic waste have been found in oceans, previous studies have indicated the levels of plastic pollution found on the surface of Lake Erie are lower than expected based on how much is entering the water. The new RIT estimate for the 3-D mass—381 metric tons—is more than 50 times greater than the previous estimates at the surface. The study also generated the first estimate of how much plastic is deposited on the bottom of the lake. It accounts for the unique properties of different types of plastics and shows that the three polymers with the lowest density—polyethylene, polypropylene and expanded polystyrene—accumulate on the surface of the lake while the other six polymers were concentrated in the sediment …” #Microplastic #PlasticWaste #FoodPackaging #SingleUsePlastic #LakeErie
