Analysis of the occurrence of microplastics in beach sand on the Brazilian coast
Researchers evaluated microplastic occurrence in beach sand along the Brazilian coastline using a simplified methodology. The study found widespread microplastic contamination and identified potential pollution sources linked to coastal urbanization and ocean currents.
Anthropogenic Litter on Beaches With Different Levels of Development and Use: A Snapshot of a Coast in Pernambuco (Brazil)
Beach litter was surveyed at nine sites in northeastern Brazil, finding plastic dominated at all beach types but with differences in litter composition linked to local activities. Characterizing litter sources at specific beaches is essential for targeted waste reduction policies.
Widespread microplastics distribution at an Amazon macrotidal sandy beach
Researchers found widespread microplastic contamination at a macrotidal sandy beach on the Amazon coast of Brazil, detecting an average of 492.5 particles per square meter with fibers dominating across three depth strata down to 60 cm.
Microplastics in brazilian marine environments: a study on beaches in São Francisco do Sul - SC
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.
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.
Contaminação Por Microplásticos Em Praias Arenosas No Brasil: Uma Revisão Sistemática
This review systematically examines microplastic contamination studies on sandy beaches across Brazil, covering publications from the first Brazilian study in 2009 onward and identifying that sediment (76% of studies), water (12%), and biota (12%) are the primary compartments investigated. The review finds tourism, fishing, and river discharge as the main microplastic sources, and identifies significant methodological gaps that limit cross-study comparisons.
Characterization of environmental microplastics present in unconsolidated sediments in coastal waters of 9 beaches on shoreline of Rio de Janeiro, Brazil
Researchers characterized environmental microplastics in unconsolidated sediments from nine beaches along the southern coast of Brazil, identifying particle abundance, morphology, color, and polymer composition. The study documented widespread microplastic contamination at all sampled coastal sites, with fragments and fibers being the dominant morphological types found in the sediment samples.
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.
Microplastic pollution across the Brazilian coastline: Evidence from the MICROMar project, the largest coastal survey in the Global South
As part of Brazil's MICROMar project, researchers analysed 4,134 samples from 1,024 beaches along approximately 7,500 km of Brazilian coastline to produce the largest standardised coastal microplastic survey in the Global South. Microplastics were found ubiquitously, with concentration patterns linked to population density, coastal morphology, and river inputs.
Abundance and characterization of microplastics on sandy beaches along the coastal area of Belize
Researchers quantified and characterized microplastic abundance on sandy beaches along the coastal zone of Belize, establishing baseline contamination data for a region of Central America and the Caribbean where such pollution assessments are critically lacking.
Abundance and distribution of solid waste and microplastics in southeastern Brazilian islands: a comprehensive analysis
Solid waste and microplastic abundance and distribution were characterized on beaches of three islands in southeastern Brazil - Trindade, Grande, and Paqueta - varying in proximity to the continent and occupation patterns. The study identified factors driving debris origin and distribution, including island remoteness, tourism, and proximity to shipping routes.
Distribution, characteristics and short-term variability of microplastics in beach sediment of Fernando de Noronha Archipelago, Brazil
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.
Saúde ambiental de praias arenosas: distribuição e níveis de contaminação na biodiversidade bêntica
This Portuguese-language study assessed environmental health of sandy beaches in Brazil, measuring microplastic distribution, contamination indices, and bioindicator organisms to evaluate ecological status and identify pollution sources along the coastline.
Occurrence and Characterization of Microplastics in Coastal Beach Sand: Insights from a Case Study at Praia Vermelha, Brazil
Researchers developed and validated a standardised protocol for collecting, processing, and characterising microplastics in beach sands at Praia Vermelha in Rio de Janeiro, Brazil, using flotation extraction and systematic sampling to demonstrate the methodology's effectiveness for identifying microplastics from coastal plastic waste disposal.

Plastic debris was found on Uruguayan beaches along a gradient of tourist use, with polypropylene and polyethylene being the most common polymers and various toxic chemicals detected on the particles. The study shows that recreational beach use is linked to higher plastic contamination in coastal environments.

Rethinking the Environmental Quality of Brazilian Beaches: The Incidence of Microplastics as Indicator for Sea Water and Sand Quality
This paper proposes using microplastic levels in beach sand and seawater as indicators of beach environmental quality, arguing that current assessments in Brazil focus too narrowly on microbial contamination. The authors present evidence that microplastic contamination poses health risks to swimmers and coastal communities that should be incorporated into beach quality standards.
