ClearMarine litter: trends and impacts in marine fauna
This review synthesizes evidence on marine litter sources, distribution, and ecological impacts, with particular focus on microplastics as a pervasive contaminant across all marine habitats. It finds that microplastics threaten marine life through ingestion, entanglement, and chemical transport, with impacts spanning trophic levels from plankton to large marine mammals.
Micro Plastics in The Marine Environment: A Review of Their Effects on Marine Organisms and Ecosystems
This review examines the effects of microplastics on marine organisms and ecosystems, summarizing evidence for MP ingestion across trophic levels, physical and chemical harm to marine life, and the pathways through which marine MP pollution threatens biodiversity and fisheries.
Efectos de la Contaminación Plástica en los Ecosistemas Marinos: Un Análisis Actualizado
This review analyzed current evidence on plastic contamination effects on marine ecosystems, examining physical entanglement, ingestion, chemical toxicity, and microplastic impacts on marine biodiversity and food web structure.
Interferência Dos Micro Resíduos De Plástico (microplásticos) No Ecossistema Marinho Do Rio Grande Do Sul - Brasil
This Brazilian Portuguese review discusses how marine debris and microplastics affect coastal ecosystems in Rio Grande do Sul, Brazil, highlighting that microplastics are more harmful than larger plastics because of their ability to adsorb toxic compounds and enter the food chain when ingested by fish.
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.
Assessment of Microplastic Impacts in the Marine Environment: A Review
This review summarizes the sources, environmental fate, and ecological impacts of microplastics in marine environments, covering impacts across food webs from phytoplankton to marine mammals. The authors identify key knowledge gaps and emphasize that biodiversity loss and food chain contamination are the most well-documented marine impacts. The review calls for integrated monitoring programs and international policy action to reduce plastic inputs to the ocean.
Plastic Interactions with Brazilian Aquatic Organisms: A Systematic Review of Research Trends and Knowledge Gaps
This systematic review summarizes research on how plastic pollution interacts with aquatic organisms across Brazil's rivers, coasts, and oceans. It identifies major knowledge gaps, including limited studies on microplastic effects in freshwater species and a lack of standardized methods. Understanding these interactions matters because contaminated fish and shellfish can carry microplastics into the human food chain.
A Review on the Impact of Plastic Debris on Marine Environment
This review summarizes the types, sources, and impacts of plastic debris in marine environments, covering both macro- and microplastics and their effects on marine biodiversity. The paper also discusses global initiatives and policy frameworks aimed at reducing marine plastic pollution.
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.
Fishing net waste management: quantification and valorization
Abandoned and discarded fishing nets are a major source of microplastics in the ocean because they are made of synthetic fibers that slowly fragment over time. This study quantified the volume of fishing net waste generated in a Portuguese fishing port and evaluated strategies for diverting it from landfill toward recycling and material recovery. Effective management of fishing gear waste is a practical lever for reducing one of the most persistent sources of marine microplastic pollution.
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.
Impacto de la Contaminación Plástica en los Ecosistemas Marinos y su Panorama Actual
This literature review synthesizes evidence on how microplastics cause digestive blockages, cellular damage, and reproductive alterations across marine trophic levels, and evaluates the limitations of current single-use plastic reduction policies in addressing the broader plastic pollution crisis.
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.
Current Progress on Marine Microplastics Pollution Research: A Review on Pollution Occurrence, Detection, and Environmental Effects
This review summarized current knowledge on marine microplastic pollution, covering detection methods, occurrence across ocean zones and organism types, and environmental effects, while identifying key research gaps around long-term ecological impacts and standardized monitoring protocols.
Effect of Plastic Ocean Pollution on Marine Life and Human Health in Brazil
This desk-study review examines how plastic ocean pollution affects marine life and human health in Brazil, synthesizing secondary data on contamination pathways and toxicological impacts.
Ecological impact of microplastic pollution on marine food webs
This review examines how microplastic pollution disrupts marine food webs, tracing the transfer of plastic particles and associated chemicals from plankton through fish to top predators and analyzing the ecological consequences for marine biodiversity and ecosystem functioning.
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.
The Current and Prospective State of Microplastic Contamination in the Marine Ecosystem
This review assesses the current state of microplastic contamination research in marine ecosystems, identifying strengths and gaps in published literature and recommending new focus areas including marine polymer degradation, advanced sampling methods, and the consequences of research-generated microplastic pollution.
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.
Microplastics in a mosaic of Marine Protected Areas from southeastern Brazil: An assessment based on filter-feeding bivalves
Researchers used filter-feeding bivalves as biological monitors to assess microplastic contamination across 28 marine protected areas along a heavily populated stretch of coastline in southeastern Brazil. They found microplastics in bivalves from all sites surveyed, demonstrating that protected status alone does not shield marine areas from plastic pollution. The study highlights how diffuse, transboundary plastic contamination reaches even designated conservation zones.
Literature Review : Kelimpahan Mikroplastik Pada Biota Laut
This Indonesian-language literature review investigates the abundance of microplastics in marine biota across 10 studies published in the past decade, examining how marine organisms inadvertently ingest microplastics while feeding and the potential impacts on marine life and human health through the food chain. The review systematically synthesizes findings on microplastic prevalence across diverse marine species and ecosystems.
