Quantification and characterization of plastics in near-shore surface waters of Atlantic Canada
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.
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.

Abundance, size and polymer composition of marine microplastics ≥ 10 μm in the Atlantic Ocean and their modelled vertical distribution
Researchers measured the abundance, size distribution, and polymer composition of microplastics 10 micrometers and larger in the Atlantic Ocean, finding widespread contamination and providing data that helps fill gaps in understanding smaller particle fractions.
Abundance, distribution and characteristics of microplastics in the North and South Atlantic Ocean
Researchers surveyed microplastic abundance across six major ocean current regions in the Atlantic Ocean, from the Netherlands to Uruguay, using 50 surface trawls. They found an overall concentration of 0.011 particles per cubic meter, with abundance significantly correlated to distance from the coast, and high-density polyethylene and polypropylene fragments being the dominant types. The study provides valuable baseline data from consistently under-sampled regions, particularly the South Atlantic.
Morphometric characteristics and spatiotemporal heterogeneity of microplastics on the north-east coast of India
Survey of surface waters along the northeast coast of India found microplastics present in all sampled water masses, with higher concentrations during the monsoon season than the post-monsoon period, and fragments and fibers making up the vast majority of particles. The seasonal pattern suggests land-based runoff is a major delivery pathway, with implications for the many coastal communities in the region that depend on these waters for fishing and livelihoods.
An evaluation of surface micro- and mesoplastic pollution in pelagic ecosystems of the Western Mediterranean Sea
Researchers found that micro- and mesoplastic debris were widely and uniformly distributed across the Western Mediterranean Sea, with average surface concentrations of approximately 130,000 microplastic particles per km2 and 5,700 mesoplastic particles per km2. Fragment morphology and polymer composition analysis indicated a predominantly land-based origin for the debris.
