Dramatic increase in microplastics in seagrass soil since the 1970s
Large-scale production of vegetables and fruit in Spain with intensive plastic consumption in its greenhouse industry is believed to have leaked microplastic contaminants since the 1970s into the surrounding Mediterranean seagrass beds. This is shown in a new study where researchers have succeeded in tracing plastic pollution since the 1930s and 1940s by analyzing seagrass sediments. (2021-01-25)

Marine pollution: How do plastic additives dilute in water and how risky are they?
New research by scientists from Korea shows that additives in plastic materials deployed or thrown in coastal environments diffuse into the environment at different rates. Their findings demonstrate how assessments of exposure risk based on the composition of the source plastic waste will be inaccurate, because this composition varies as plastics break down and additives dilute into the environment at different rates. A new evaluation method is needed, and these scientists have just the solution! (2020-12-14)

Natural environmental conditions facilitate the uptake of microplastics into living cells
The environment is polluted by microplastics worldwide. A research team at the University of Bayreuth has now discovered that microplastic particles find their way into living cells more easily if they were exposed to natural aquatic environments, i.e. fresh water and seawater. Biomolecules occurring in the water are deposited on the microplastic surfaces, which promote the internalization of the particles into cells. (2020-12-10)

Study first to tally biomass from oceanic plastic debris using visualization method
Scientists examined cell abundances, size, cellular carbon mass, and how photosynthetic cells differ on polymeric and glass substrates over time, exploring nanoparticle generation from plastic like polystyrene and how this might disrupt microalgae. Conservative estimates suggest that about 1 percent of microbial cells in the ocean surface microlayer inhabit plastic debris globally. This mass of cells would not exist without plastic debris in the ocean, and thus, represents a disruption of the proportions of native flora in that habitat. (2020-10-13)

There is at least 10 times more plastic in the Atlantic than previously thought
Scientists measured 12-21 million tonnes of three of the most common types of plastic in the top 200 metres of the Atlantic. By assuming the concentration of plastic in the whole Atlantic is the same as that measured at 200 metres deep, the scientists estimated there is around 200 million tonnes of three of the most common types of plastic alone. Compare this to the previously estimated figure of 17 million. (2020-08-18)

Now, a new material reported in ACS Applied Materials & Interfaces can be used to 3D print small objects that expand upon heating. The foam could find applications in architecture, aerospace and biomedicine. (2020-05-13)
