Microplastics Santa Catarina Island
AI summary Read the abstract
This dataset contains oxidation index measurements for plastic pellets collected from sandy beaches on Santa Catarina Island, Brazil, providing data on the weathering and degradation state of beached plastic. Oxidation indices help researchers understand how long plastics have been in the environment and how degraded they are.

Plastic Pellets on Campeche Beach (Santa Catarina Island, Brazil): A Seasonality and Composition Study
AI summary Read the abstract
Researchers measured the abundance of plastic pellets on a beach in Santa Catarina Island, Brazil, across seasons, finding higher levels in summer and lower levels in winter. Seasonal variation in pellet abundance was linked to wind and wave patterns, which influence both pellet deposition and resuspension from beach sediments.
Microplastics in brazilian marine environments: a study on beaches in São Francisco do Sul - SC
AI summary Read the abstract
Beach surveys along São Francisco do Sul in southern Brazil confirmed widespread microplastic presence in coastal sediments, with polymer composition reflecting regional plastic waste streams. The study adds to the body of evidence that Brazilian coastlines are significantly contaminated and calls for national monitoring standards to track and manage the problem.
Inter-Compartment Comparison of Weathering Extent of Microplastics Using Carbonyl Index and Its Application in Source Identification
AI summary Read the abstract
Researchers used carbonyl index measurements to quantify the weathering extent of microplastics collected from different environmental compartments—beach sand, river water, atmospheric deposition—and evaluated whether weathering extent can be used to identify plastic sources. Results showed that carbonyl index successfully distinguished microplastics from different exposure environments and could serve as a weathering fingerprint for source attribution.
Quantification of microplastics on anthropized and little anthropized beaches in Rio Grande do Sul coast, Brazil
AI summary Read the abstract
Researchers analyzed microplastics in beach sediments at three sites on the northern coast of Rio Grande do Sul, Brazil, across all four seasons. Microplastic abundance was higher at more urbanized beaches and varied seasonally, reflecting differences in anthropogenic pressure and local conditions.
Quantification and characterization of microplastics on the coast of Rio Grande do Sul
AI summary Read the abstract
Microplastics were quantified and characterized along the coast of Rio Grande do Sul in southern Brazil, with fragments and films being the most common types found in beach sediments. Plastic pollution was present along the entire surveyed coastline, reflecting widespread inputs from land-based sources and ocean currents. The data provide a baseline for tracking changes in plastic contamination along this Atlantic coast over time.
