Microplastics – Transport and Burial in Deep-Marine Sediments

According to a March 6, 2020 Environmental Science & Technology article by researchers with Durham University, Durham UK; Utrecht University, The Netherlands; University of Manchester, UK; and National Oceanography Centre, Southampton UK https://pubs.acs.org/doi/10.1021/acs.est.9b07527 “... The threat posed by plastic pollution to marine ecosystems and human health is under increasing scrutiny. Much of the macro- and microplastic in the ocean ends up on the seafloor, with some of the highest concentrations reported in submarine canyons … Gravity-driven avalanches, known as turbidity currents, are the primary process for delivering terrestrial sediment and organic carbon to the deep sea through submarine canyons … Our results suggest that turbidity currents potentially distribute and bury large quantities of microplastics in seafloor sediments …” #MicroPlastics #SingleUsePlastic #PlasticWaste
