Microplastics in beluga whale (Delphinapterus leucas) prey: An exploratory assessment of trophic transfer in the Beaufort Sea

We investigated microplastic ingestion and transfer within the Beaufort Sea Beluga whale food web. Using five fish species key to the Beluga whale diet we found microplastics ingestion in one in five of the animals. Microplastics were dominated by synthetic fibers, consistent with the Beluga whale contamination trends in our recent study.
