Prevalence of microplastics in the ocean in Latin America and the Caribbean
Summary
This review assessed microplastic prevalence in ocean waters across Latin America and the Caribbean, finding that mismanaged waste and wastewater are critical pollution sources, while highlighting the need for more research on effects on local biota and human health.
The release of microplastics to the ocean is an increasing global environmental concern. The specific characteristics of the Global South (e.g., widespread mismanaged waste and wastewater) make this an even greater challenge. The current study performed a critical review related to the prevalence of microplastics in the ocean in Latin America and the Caribbean, analyzing also the possible sources of microplastics release to the marine environment. A majority of the studies assessed point towards mismanaged waste, inland or offshore, as well as mismanaged wastewater as critical sources of plastic pollution into the ocean. However, there is a need to delve into the effects that these microplastics are generating on local biota and human health.

Microplastics in Latin America and the Caribbean: A review on current status and perspectives
This review assessed the current status of microplastic research across Latin America and the Caribbean, covering occurrence in water, sediments, and soil, as well as effects on aquatic and terrestrial organisms, and identifying key knowledge gaps in the region.
Microplastics in Latin America Ecosystems: A Critical Review of the Current Stage and Research Needs
This systematic review of 196 studies reveals that Latin America, which consumes 8% of the world's plastic but recycles only 4.5%, has significant gaps in microplastic contamination data. Understanding the distribution of microplastics in Latin American ecosystems is critical for assessing potential health risks to the region's populations.
The Occurrence of Microplastics in the Marine Food Web in Latin America: Insights on the Current State of Knowledge and Future Perspectives
This review examines microplastic contamination in marine organisms across Latin America, where wastewater, industry, and plastic breakdown are major sources. Microplastics were found in fish, shellfish, seabirds, and other marine life, entering the food chain through ingestion and passing between species. Since many of these organisms are eaten by people, the findings raise concerns about human exposure to microplastics through seafood in the region.
Where and how? A systematic review of microplastic pollution on beaches in Latin America and the caribbean (LAC)
Microplastic contamination on Latin American and Caribbean beaches ranged from 0 to 5,458 particles/m2, with the highest accumulations found on ocean island beaches. Brazilian beaches accounted for 43% of all studies, while large stretches of coastline in Cuba, Venezuela, and Argentina had no data, and inconsistent methodologies prevented meaningful cross-study comparison.
Review of current trends, advances and analytical challenges for microplastics contamination in Latin America
This review compiled 78 studies on microplastic contamination across Latin America and found that research in the region remains limited, with Brazil accounting for 34% of all studies. Fibers were the most prevalent microplastic type found, making up 62% of particles, with polyethylene, polypropylene, PET, and polystyrene accounting for 80% of identified polymers. The study highlights significant gaps in standardized methodologies that make it difficult to establish baseline microplastic pollution levels across the region.
