Summary

Researchers quantified and characterised plastic pollution in near-shore surface waters at three locations across Atlantic Canada, finding an average abundance of 9,669 items/km with microplastics (0.425-5 mm) comprising 68% of particles, polyethylene accounting for 30% of all particles, and plastic fragments as the most common morphological type.

Polymers

Plastics are a ubiquitous pollutant in the marine environment. Despite growing concerns, quantitative and qualitative data on microplastics in aquatic and marine environments of Atlantic Canada is just emerging. Surface water plastics were measured and categorized by morphology (thread, microfibre, fragment, foam, film, pellet, and microbead) in two locations in Nova Scotia and one in Newfoundland and Labrador, Canada. All sites within the three locations contained plastic with an average abundance of 9669 items/km. Most plastics (68 %) were sized as microplastics (0.425-5 mm), and plastic fragments were the most common morphological type. Polyethylene accounted for a third (30 %) of all particles found across all three locations, followed by polypropylene (23 %). Results can inform future research for community-based environmental groups, government, and academia.
