ClearContaminação 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.
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.
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.
Investigação científica de microplásticos na praia Pedra do Sal em Parnaíba – Piauí
This Brazilian Portuguese study assessed microplastic pollution in beach sediments at Pedra do Sal beach in Parnaíba, documenting contamination in an area with limited prior research. The study contributes to baseline data on microplastic contamination along Brazil's northeastern coastline.
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.
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.
Dispersão de microplásticos em águas superficiais e sedimentos de fundo da plataforma continental de Fortaleza
Researchers examined the distribution and characteristics of microplastics in surface waters and bottom sediments of the continental shelf off Fortaleza, Brazil, characterizing MP abundance and morphology to assess contamination levels in this South American marine environment.
Presença de microplásticos em sedimento intertidal e tecidos de bivalves economicamente importantes: avaliação pós-engordamento de trechos de praias urbanas
Researchers compared microplastic abundance in intertidal sediments and tissues of four bivalve species collected from two urban beaches in Vitória, Brazil following a beach fattening process, aiming to characterize the distribution and types of microplastics present in both environmental and biological matrices in a post-nourishment context.
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.
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.
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.
Tracking Microplastics in Paradise: First Evidence of Pollution in Lençóis Maranhenses National Park (Maranhão, Brazil), a UNESCO World Heritage Site
Researchers conducted the first assessment of microplastic pollution in Lencois Maranhenses National Park, a UNESCO World Heritage Site in Brazil, documenting MP presence, characteristics, and potential sources in this previously unstudied protected coastal ecosystem.
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.
Plastics and microplastics on recreational beaches in Punta del Este (Uruguay): Unseen critical residents?
Researchers assessed plastic and microplastic pollution on recreational beaches in Punta del Este, Uruguay, finding contamination levels that reflected tourist activity and coastal currents, and raising concerns for beach users and coastal ecosystems.
