ClearConsequências Dos Microplásticos Para Os Peixes Marinhos: Uma Revisão De Literatura
This literature review examines the consequences of microplastic ingestion and exposure for marine fish, synthesizing evidence on physiological and behavioral harms including impaired feeding, oxidative stress, and reproductive disruption across multiple species.
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.
Efeitos dos Microplásticos
This article reviews the effects of microplastics on organisms and ecosystems, summarizing ecotoxicological evidence from studies on marine and freshwater species as well as emerging data on human exposure. The review is written in Portuguese and covers impacts ranging from physical ingestion effects to chemical toxicity from plastic-associated compounds.
Efectos de los microplásticos en el medio ambiente: Un macroproblema emergente
This review (written in Portuguese) summarizes the environmental effects of microplastics, noting that 300 million tonnes of plastic are produced annually with millions entering rivers and oceans. It highlights the irreversible ecological damage microplastics can cause to organisms with limited adaptive capacity.
Ingestão e efeitos morfofisiológicos dos microplásticos em espécies de peixes da Amazônia Central
This Brazilian thesis investigates microplastic ingestion and its effects on fish from the Amazon basin, one of the world's most biodiverse freshwater systems. Given that aquatic organisms in even remote areas are exposed to microplastics, the research highlights risks to Amazon fish diversity and the potential for microplastics to disrupt aquatic food webs in previously pristine ecosystems.
Microplásticos, Seus Impactos No Ambiente E Maneiras Biodegradáveis De Substituição.
This Portuguese-language review examined microplastics as major aquatic and terrestrial pollutants, summarizing their sources, environmental distribution, and impacts on ecosystems, and reviewing biodegradable alternatives as a strategy to reduce future plastic fragment accumulation.
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.
Microplastics in marine and estuarine environments: bibliographic review, distribution (Ilha Grande Bay - RJ), biofilm composition (Guanabara Bay - RJ) and changes in sinking rate
This work reviewed microplastic distribution in Brazilian marine and estuarine environments, surveyed Ilha Grande Bay, analyzed plastisphere biofilm communities in Guanabara Bay, and examined how biofilm colonization affects microplastic sinking rates. Biological coating of plastic particles changes their transport and fate in the ocean.
Microplastics contamination and toxicity in a coastal marine protected area
This study examined microplastic contamination and toxicity in a Brazilian coastal marine protected area, finding plastic particles accumulating on beaches and posing risks to filter-feeding organisms and marine food webs. Even protected coastal areas are not shielded from microplastic pollution.
Microplastic contamination in demersal and pelagic fish from two differently anthropized bays on the south coast of Rio de Janeiro, Brazil
Researchers investigated microplastic contamination in demersal and pelagic fish from two bays with differing levels of human impact on the south coast of Rio de Janeiro, Brazil. The study compared microplastic occurrence across fish species and sampling sites to assess how anthropisation influences microplastic exposure in coastal fish populations.
Impactos clínicos, sociais, tóxicos e ambientais causados pela exposição contínua e sistêmica de microplásticos no ecossistema brasileiro
This Brazilian review examines the clinical, social, toxic, and environmental impacts of continuous systemic microplastic exposure in the Brazilian ecosystem, noting that 8.3 billion tons of virgin plastics have been produced globally. The authors discuss how plastic fragmentation into microparticles threatens Brazilian biodiversity, food safety, and human health through multiple exposure pathways.
Ingestion of plastic debris by commercially important marine fish in southeast-south Brazil
Scientists visually examined 965 specimens of eight commercially exploited fish species off the southeast-south coast of Brazil for plastic debris ingestion, finding plastic in multiple species across different marine habitats.
Influência Dos Microplásticos E Nanoplásticos No Meio Ambiente E Na Saúde Humana
This Portuguese-language review summarizes evidence that microplastics and nanoplastics are now ubiquitous in the environment and in the human body — found in breast milk, fish digestive tracts, and elsewhere — and can carry toxic compounds like hydrocarbons and heavy metals that amplify their harm. The authors highlight particular concern for infant exposure through breast milk and for human ingestion via commonly eaten fish like sardines. The paper reinforces the urgent need for regulatory action to reduce plastic pollution given its demonstrated reach into human biology.
Dampak Mikroplastik terhadap Ekosistem Pesisir: Sebuah Telaah Pustaka
This Indonesian-language review examines the impacts of microplastics on coastal ecosystems, covering effects on marine organisms, sediment quality, and food web dynamics. The paper highlights the vulnerability of tropical coastal environments to plastic pollution from both land-based and marine sources.
Evaluation of microplastic in the digestive tract of fish species in the vicinity of the Itaqui Port Complex, São Luís – MA
Researchers evaluated microplastic content in the digestive tracts of fish species collected in the vicinity of the Itaqui Port Complex in São Luís, Maranhão, Brazil. The study characterised microplastic presence and quantity in fish from a commercially and industrially active coastal area, contributing to the understanding of microplastic contamination in South American estuarine fish communities.
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.
Presença e efeitos da poluição plástica em peixes marinhos e de água doce
This thesis (in Portuguese) investigates plastic contamination in freshwater and marine fish, examining physiological, functional, and ecological effects across multiple levels of biological organization, including food safety implications for human consumption. The author finds that the scientific community has made progress on understanding individual-level effects but that broader ecological impacts and ecosystem-level consequences remain underexplored. The work contributes important evidence that plastic pollution in fish poses intertwined risks for wildlife and the people who eat them.
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.
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.
Contamination by plastics and microplastics: (re)knowing the lived reality.
This Brazilian literature review examines the environmental impact of plastics and microplastics across different pollution scenarios, discussing the history of plastic production and consumption, relevant environmental legislation, and the importance of recycling in addressing plastic contamination.
