Occurrence and characteristics of microplastics on insular beaches in the Western Tropical Atlantic Ocean
AI summary Read the abstract
Researchers found microplastics on beaches of three remote Atlantic islands — Fernando de Noronha, Abrolhos, and Trindade — with plastic fragments predominating over fibers, demonstrating that even isolated island beaches far from population centers accumulate ocean plastic debris.
Microplastics are widespread throughout oceans and seas and beaches are no exceptions. On beach sediments, microplastics (<5mm) are commonly prevalent over macroplastics (>5mm), where fragments of larger items are sampled in greater amounts. The occurrence and characteristics of microplastics were investigated on beaches of Fernando de Noronha, Abrolhos and Trindade islands located in the western tropical Atlantic Ocean. Despite no microplastic was identified in Abrolhos at this time, small spatial variations were detected in Fernando de Noronha and Trindade islands, highlighting the importance of oceanographic variables on plastics distribution and accumulation over time.

Occurrence and characteristics of microplastics on insular beaches in the Western Tropical Atlantic Ocean
AI summary Read the abstract
Researchers sampled microplastics on beaches of three remote Brazilian oceanic islands in the western tropical Atlantic and found particles on two of the three islands, with fragments being the most common type. The presence of microplastics even on these isolated islands confirms that ocean currents carry plastic contamination far from coastal population centers.
Small microplastics on beaches of Fernando de Noronha Island, Tropical Atlantic Ocean
AI summary Read the abstract
Researchers characterized small microplastics (under 1mm) on 15 beaches of Fernando de Noronha Island in the tropical Atlantic, a protected Brazilian oceanic island. Synthetic fibers were the most common type found, with both windward and leeward beaches contaminated, demonstrating that even remote, protected islands are not free from microplastic pollution.
Contaminação ambiental por microplásticos em Fernando de Noronha, Abrolhos e Trindade
AI summary Read the abstract
This study characterized microplastic contamination at three remote Brazilian islands - Fernando de Noronha, Abrolhos, and Trindade - finding plastic particles in ocean surface waters, beach sediments, and deep sediments. The findings highlight that even isolated, protected marine areas are not immune to microplastic pollution.
Distribution, characteristics and short-term variability of microplastics in beach sediment of Fernando de Noronha Archipelago, Brazil
AI summary Read the abstract
Researchers conducted daily beach sediment sampling on Fernando de Noronha Archipelago in Brazil, documenting large spatial and temporal variability in microplastic concentrations (0.6-1,059 particles/m) and finding that remote island beaches are not protected from microplastic contamination.
Plastic pollution in islands of the Atlantic Ocean
AI summary Read the abstract
A survey of plastic pollution on beaches of Atlantic Ocean islands from the Azores to Tristan da Cunha found microplastics and macroplastics at all locations, with composition suggesting origin from both local and long-distance ocean transport. The findings confirm that even remote Atlantic islands serve as sinks for globally circulating plastic debris.
