Origins and Biological Accumulation of Small Plastic Particles in Fur Seals From Macquarie Island
From the abstract of the referenced paper: One hundred and sixty four plastic particles (mean length 4.1 mm) recovered from the scats of fur seals (Arctocephalus spp.) on Macquarie Island were examined. Electron micrographs of 41 of the plastic particles showed that none could be identified as plast...
