Microplastics Found in Marine Mammals

Marine mammals such as dolphins and seals are found ingesting microplastics. Microplastics were found in the guts of all the marine animals (50 individuals and 10 species) studied according to the authors.

Note: a small proportion of fibres were larger than 5 mm but were not macroscopically visible and are included here. (d) the proportion of polymer types found.
