Caracterização de microplásticos em amostras marinhas e estuarinas

This study characterized microplastics collected from marine and estuarine samples in Brazil, classifying them by size, shape, and polymer type. The findings document the widespread presence of microplastic contamination in these coastal ecosystems and provide baseline data for future monitoring.

Microplástico em ambientes recifais da costa do Ceará, Nordeste brasileiro

Researchers documented the first record of microplastics in the skeleton of a reef-building coral species in the South Atlantic and tested whether proximity to polluted estuaries and regional population density influence microplastic concentration in reef sediments along the Ceara coast of northeastern Brazil. Sediment was collected from five reef environments including sites near Fortaleza, providing baseline data on microplastic accumulation in tropical reef ecosystems.

Meso- and microplastic composition, distribution patterns and drivers: A snapshot of plastic pollution on Brazilian beaches

A standardized survey of plastic pollution across 22 sandy beaches spanning over 4600 km of Brazilian coast found widespread contamination in coastal sediments, with polymer type, size, and distribution patterns reflecting diverse sources including fishing activity and urban runoff.

Microplastic pollution in Brazil's coastal marine surface waters: The first macroregional baseline from the global south

Researchers conducted the largest microplastic survey in the Global South, sampling 4,134 surface water sites across 7,500 km of Brazilian coastline, finding the highest concentrations in the Eastern Coastline (16.87 MPs/L) and lowest in the Amazonian Equatorial region (1.29 MPs/L), with spatial patterns driven by hydrodynamic conditions, salinity, proximity to sewage, and anthropogenic inputs.

Contaminación por microplásticos en las playas de Crucita, Ecuador: abundancia y composición de polímeros

Researchers quantified microplastic abundance and identified polymer types in sand samples from three beaches in Crucita, Ecuador, characterizing the contamination profile of this South American coastal environment and contributing to regional baseline data on MP pollution.

Variação espaço-temporal de microplásticos nas águas superficiais de um estuário urbano no nordeste do Brasil

Researchers evaluated the spatial and temporal variation of microplastics in surface waters of the Cocos River urban estuary in Fortaleza, northeastern Brazil, collecting samples at three points along the estuary over time to characterize longitudinal and seasonal patterns. The study linked microplastic concentrations to land use, urban effluent discharge, and solid waste inputs, identifying this estuary as a significant pathway for microplastic transport to the ocean.

Contaminação e toxicidade de microplásticos em uma área de proteção marinha costeira

This Brazilian study assessed microplastic contamination and toxicity in a coastal marine protected area, finding that sandy beaches accumulate plastic particles carried in by the ocean. The research highlights that even protected coastal zones are not immune to microplastic pollution, which can be ingested by marine wildlife and enter food webs.

Microplastics Identification in an Environmental Reserve Area of Ilha de Itamaracá - PE

Researchers identified and characterized microplastics in water, sediment, and biota from an environmental reserve area in Brazil, documenting contamination by particles originating from both fragmentation of larger plastic items and primary microplastics, showing that even protected coastal areas are not free of MP pollution.

Microplastic occurrence, distribution, and zonation at Paraná’s beaches—South of Brazil

Researchers conducted the first survey of microplastic distribution and zonation on beaches in Paraná state, southern Brazil, characterizing MP concentrations, polymer types, and morphologies across multiple beach zones to establish a baseline for this understudied South American coastline.

Microplastics on Santos Beach: Sources of Pollution, Waste Characteristics and Possible Collection Solutions

Researchers characterized microplastics collected from three zones of Santos beach in Brazil, finding contamination dominated by fragments and films near sewage outfalls. The study highlights inadequate waste management as the primary driver of beach microplastic accumulation and assessed feasibility of mechanical collection interventions.
