Dear colleagues,

My co-authors and I are excited to share with you the publication of our
research article “First report from North America of microplastics in the
gastrointestinal tract of stranded bottlenose dolphins (*Tursiops truncatus*)”
in the journal Marine Pollution Bulletin.

Microplastics' (MPs) abundance, small size, and global distribution render
them bioavailable to a variety of organisms directly or by trophic
transfer, yet examinations in marine apex predators are currently limited.
The present study investigated the occurrence of MPs sized 125 μm–5 mm in
the gastrointestinal tract (GIT) of bottlenose dolphins (*Tursiops
truncatus*) stranded in South Carolina, USA from 2017 to 2018. MPs, mostly
fibers, were detected in all GITs (*n* = 7) of stranded bottlenose
dolphins. Total suspected MPs ranged between 123 and 422
particles/individual, a high range among international studies. Comparison
to other studies likely reflects differences in both methods and location.
This is the first study from North America to quantify MPs in a small
coastal cetacean outside Arctic waters and the first specifically in
bottlenose dolphins (southeastern United States). Findings and methodology
from this investigation can aid future studies examining MP in marine apex
