ClearMicroplastics on Santos Beach: Sources of Pollution, Waste Characteristics and Possible Collection Solutions
This Brazilian study mapped and characterized microplastic contamination on Santos beach near submarine sewage outfalls and storm drains, finding plastic pollution hotspots linked to coastal discharge infrastructure. The authors estimated that ~60 tons of solid waste enter the sea daily in the region and identified possible collection solutions.
Litter assessment on sandy beaches along the Brazilian coast: a large-scale analysis of macrolitter and microplastics
Researchers conducted a large-scale assessment of macrolitter and microplastic contamination on sandy beaches along the Brazilian coast, characterizing pollution patterns, dominant polymer types, and potential anthropogenic sources across multiple sites.
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.
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.
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.
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.
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.
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.
Evaluation of microplastic and marine debris on the beaches of Niterói Oceanic Region, Rio De Janeiro, Brazil
Researchers evaluated microplastic and marine debris on ocean beaches of Niterói, Brazil, across winter and summer seasons, finding seasonal variation in abundance with fragments and films predominating and highlighting recreational beaches as significant accumulation zones.
Microplastic Hotspots on a Tropical Estuarine-Bay System
Researchers mapped microplastic hotspots in the Santos Estuarine System in Brazil — the most populous estuary and largest seaport in the country — characterizing accumulation and export dynamics of microplastics in a high-traffic coastal environment.
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.
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.
Microplastics in surface waters of tropical estuaries around a densely populated Brazilian bay
Researchers found extremely high microplastic concentrations (up to 33,000 items per cubic meter) in ten estuaries around Todos os Santos Bay, Brazil, largely driven by deficient domestic wastewater treatment serving over 3 million residents.
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.
Microplastic levels on sandy beaches: Are tourism and coastal recreational activities effects really important?
Researchers assessed microplastic levels at six sites across three Argentine sandy beaches with varying tourism intensity, finding concentrations averaged 1,133 items/kg in sand and 12.7 items/m3 in seawater, dominated by PE films and PET/cotton fibers. Contrary to expectations, the highest microplastic concentrations and smallest particles were found at a low-activity 'pristine' site, suggesting river proximity and coastal drift rather than tourism are the dominant local pollution drivers.
Microplastic in the sediments of a highly eutrophic tropical estuary
Researchers quantified and characterized microplastics in sublittoral sediments of Guanabara Bay, a highly eutrophic tropical estuary in Brazil, finding widespread contamination with fibers and fragments at concentrations reflecting the bay's heavy urbanization and poor waste management.
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.
Spatio-temporal evaluation of macro, meso and microplastics in surface waters, bottom and beach sediments of two embayments in Niterói, RJ, Brazil
Researchers evaluated macro, meso, and microplastic distribution across surface waters and sediments in two Brazilian embayments, finding microplastics comprised 83% of collected waste with highest concentrations (138.41 items/kg) in beach sediments dominated by HDPE, polypropylene, and styrene. Beach sediments showed elevated microplastic concentrations during the rainy season and were identified as the most informative compartment for tracking plastic waste dynamics over time.
