Trophic transfer of microplastics in Phalacrocorax auritus (Double-Crested Cormorants) and fish in Lake Champlain
The goal of this research was to determine whether microplastics (MP) result in trophic transfer within invertebrates, fish, and Phalacrocorax auritus (Double-crested Cormorants) resident to Lake Champlain. We did so by quantifying and characterizing (e.g., fragment, fiber, film, foam, pellet) plast...
