Summary

Researchers analyzed microplastics in stomach, colon, and muscle tissues from bowhead whales harvested by Alaska Natives for subsistence, aiming to characterize contamination in this ecologically and culturally important Arctic species. Microplastics were present across all sampled tissue types, raising concerns for both whale health and human dietary exposure through traditional harvesting.

Mentor: Dr. Lara Horstmann; Microplastics (particles < 5mm) are present in all oceans. They were isolated from marine mammals harvested by Alaska Natives, making this emerging contaminant concerning for animal and human health. We will analyze bowhead feces and tissues to understand microplastic uptake and accumulation in an endangered Arctic species of subsistence importance.
