Presence of microplastics in six bivalve species (Mollusca, Bivalvia) commercially exploited at the Pacific coast of Costa Rica, Central America
Researchers found microplastics in all six commercially exploited bivalve species sampled from the Pacific coast of Costa Rica, with prevalence ranging from 74% to 100% across species, raising concerns about human exposure through seafood consumption in Central American coastal communities.
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.
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.
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.
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.
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.

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.
