Four hundred three pieces of plastic removed from sable shearwater A. carneipes 90-day-old chick.
On the left are five plastic items (0.073 g) removed during lavage, and on the right are the 398 items (41.812 g) that remained inside the stomach after lavage. The 398 items could not be removed during lavage as the large volume of plastic created a blockage. Instead, these items were recorded during necropsy after the bird was deceased. Pumice (128 pieces, 6.819 g) and squid beaks (not counted) also ingested by the bird are displayed in the petri dishes
Most worryingly, we found evidence of neurodegeneration in <90-day-old seabird chicks with high levels of ingested plastic - protein expression signatures akin to what we see in human patients with dementia, Alzheimer's and Parkinson's (3/5)
