Prevalence of microplastic contamination in the digestive tract of fishes from mangrove ecosystem in Cispata, Colombian Caribbean
Scientists examined the digestive tracts of fish from mangrove ecosystems in Cispata, Colombian Caribbean, finding microplastics in multiple species and suggesting that mangrove habitats concentrate microplastic pollution in ways that expose fish inhabiting these nursery areas.
Microplastics pollution on Colombian Central Caribbean beaches
Researchers conducted a baseline survey of microplastic contamination on Colombia's Central Caribbean Coast beaches, documenting MP types, sizes, and polymer compositions for the first time in that region and finding primarily secondary microplastics from fragmented larger debris.
Microplastics in water and fish of commercial interest: Distribution and relation to ecology in the colombians caribbean region, south america
Researchers evaluated microplastic contamination in surface waters and the gastrointestinal tracts of two commercially important fish species and one invasive species along the Caribbean coast of Colombia's Atlantico department and San Andres Island, relating distribution patterns to the ecology and geographic range of each species.
Occurrence of microplastics in bivalve molluscs Anomalocardia flexuosa captured in Pernambuco, Northeast Brazil
Researchers documented microplastic contamination in bivalve molluscs (Anomalocardia flexuosa) from estuaries in northeastern Brazil, finding widespread presence of microplastics in shellfish consumed by traditional communities, raising concerns about human dietary exposure.
A year-long monitorization of microplastic pollution in a bivalve aquaculture located at a coastal lagoon from Portugal
Researchers conducted a year-long quarterly monitoring study of microplastic contamination in Crassostrea gigas (diploid and triploid) and Ruditapes philippinarum bivalves from a Portuguese coastal lagoon aquaculture, alongside monthly water and sediment sampling. Microplastics were detected in every environmental matrix and in all tissue types examined, including muscle, digestive gland, gills, and visceral mass, demonstrating persistent contamination throughout the aquaculture system.
Methods to characterize Microplastics: Case study on freshwater fishes from a tropical lagoon in Colombia
Researchers examined microplastic prevalence, abundance, and physical and chemical characteristics in fish from Luruaco lagoon, Colombia, conducting four sampling events using trawl nets and analyzing gastrointestinal tracts of captured individuals to characterize microplastic ingestion across species.
Microplastic pollution in coastal areas of Colombia: Review
This review summarized the state of microplastic research in Colombia's coastal areas, finding that Caribbean coasts are most contaminated with secondary polypropylene and polyethylene microplastics in sediments, and that 7% of 302 fish species sampled contained microplastics, while noting a lack of standardized methods across studies.
Abundance, distribution, and characteristics of microplastics in coastal surface waters of the Colombian Caribbean and Pacific
This study documented microplastic abundance, distribution, and characteristics across Colombian Caribbean and Pacific coastal surface waters during the 2017 rainy season, finding concentrations up to 8.96 items per square meter and establishing the first national baseline for microplastic pollution in Colombian coastal waters.
Microplastic pollution in water, sediments and commercial fish species from Ciénaga Grande de Santa Marta lagoon complex, Colombian Caribbean
Microplastics were detected in water, sediment, and fish from the Ciénaga Grande de Santa Marta lagoon in the Colombian Caribbean, with concentrations varying by matrix and site. The study represents an early baseline for plastic pollution monitoring in this ecologically important tropical lagoon ecosystem.
Microplastic contamination in commercially important bivalves from the southwest coast of India
Microplastics were detected in water and three commercially important bivalve species along the southwest coast of India, with concentrations varying by species and collection site. The presence of plastic particles in filter-feeding shellfish intended for human consumption raises concerns about dietary exposure.
Bivalves with potential for monitoring microplastics in South America
Researchers tested three South American mussel species and found that all of them accumulated microplastics in their tissues, feces, and pseudofeces, suggesting these bivalves can serve as reliable bioindicators — living monitors — for microplastic contamination in coastal waterways.
Microplastic in clams: An extensive spatial assessment in south Brazil
Researchers assessed microplastic contamination in clams collected from extensive coastal regions of southern Brazil. They found microplastics in the soft tissues of clams across all sampling sites, with contamination levels influenced by proximity to urban areas, rivers, and local water flow patterns. The study highlights that even organisms in less urbanized coastal areas are accumulating microplastics, raising concerns about widespread contamination in shellfish habitats.
Assessing microplastic pollution along the Caribbean coast of La Guajira, Colombia
Researchers conducted the first assessment of microplastic pollution along 125 km of the Caribbean coast of La Guajira, Colombia. They found microplastics at four of seven beaches sampled, with filaments from fishing activities predominating and polymers primarily consisting of polypropylene, polyethylene, and polystyrene.
Microplastics of surface waters of Colombian Caribbean
Researchers collected and characterized microplastics from the surface waters of two Colombian Caribbean sectors influenced by major rivers, sampling across dry and rainy seasons and also analyzing the microbial communities living on the plastic surfaces. The study provides baseline pollution data for a region where microplastic research has been minimal, while the metagenomic analysis of plastisphere microbes adds ecological context. Understanding which microbes colonize plastic in tropical Caribbean waters is relevant to assessing whether those particles serve as vectors for harmful or antibiotic-resistant bacteria.
Presence of microplastics: Impacts in a marine-coastal environment of the Colombian Caribbean
Researchers surveyed microplastic presence in a marine-coastal environment in Colombia, characterizing particle abundance, polymer types, and size distribution in water and sediment samples. Fibres dominated the samples, with polyester and nylon the most common polymers, pointing to synthetic textile washing as a key local source.
Microplastics in global bivalve mollusks: A call for protocol standardization
Researchers reviewed 61 studies on microplastic contamination in bivalve mollusks worldwide, finding that these filter-feeding shellfish consistently contain microplastics regardless of location. The study found significant differences in contamination levels between bivalve families based on their habitats, suggesting that both water-dwelling and sediment-dwelling species can be used to monitor different types of microplastic pollution. The authors call for standardized sampling and analysis protocols to enable meaningful comparisons across future studies.

Researchers found that all four species of bivalves sold in Brazilian markets contained microplastics, averaging 1.64 particles per gram, confirming that commercially sold shellfish are a source of microplastic exposure for consumers.
Microplastic ingestion and feeding ecology in three intertidal mollusk species from Lima, Peru
Three intertidal mollusk species from the coast of Lima, Peru were assessed for microplastic ingestion in relation to their feeding ecology. The study found microplastics in all three species, with ingestion levels varying by feeding strategy and local contamination levels.
Widespread microplastic ingestion in Colombian Caribbean marine fish: Trophic influence, spatial-temporal trends, and polymer composition
Researchers examined three commercially important fish species from the Colombian Caribbean and found microplastics in over 82% of individuals across both continental and island waters. Fiber and fragment shapes were the most common types, with higher concentrations found in coastal areas and during the wet season. The findings suggest that microplastic ingestion is widespread among Caribbean fish, with potential implications for seafood consumers in the region.
