ClearMarine litter and microplastic pollution on mangrove soils of the Ciénaga Grande de Santa Marta, Colombian Caribbean
Researchers assessed marine litter and microplastic contamination in mangrove soils of Colombia's largest coastal lagoon system for the first time. They found significantly higher litter concentrations near populated areas, with plastics comprising up to 96% of all debris, and microplastic levels varying widely across sampling sites. The study highlights the link between inadequate waste management in coastal communities and microplastic accumulation in ecologically important mangrove habitats.
Impacts of marine debris contamination in the mangrove ecosystem of the Ciénaga Grande de Santa Marta, Colombian Caribbean
This study assessed the impacts of marine debris, including plastic, on the mangrove ecosystem of Colombia's Ciénaga Grande de Santa Marta, finding widespread contamination with negative effects on both ecology and local communities. Mangroves are important coastal filters but are being overwhelmed by plastic inputs.
Seasonal variation in plastic litter pollution in mangroves from two remote tropical estuaries of the Colombian Pacific
Researchers found that plastic litter in two remote Colombian Pacific mangrove estuaries was dominated by microplastics, with higher abundances during high-rainfall seasons in both surface waters and sediments, and foams and fragments being the most common types.

Researchers identified and assessed the negative impacts of marine debris pollution on the mangrove ecosystem of the Ciénaga Grande de Santa Marta in the Colombian Caribbean, documenting observed and potential impacts through field surveys conducted in February 2018.
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.
Litter Content of Colombian Beaches and Mangrove Forests: Results from the Caribbean and Pacific Coasts
This study surveyed litter abundance and types at beaches and mangrove forests on both Colombian Caribbean and Pacific coasts, finding that Caribbean sites had higher plastic litter loads than Pacific sites and that mangrove forests accumulated significant quantities of debris, highlighting the role of coastal vegetation as litter traps.
Marine debris in tourism area of Dodola Island Beach, Morotai Island District
This paper is not directly about microplastics; it characterizes the composition and density of marine debris on a tourism beach in Morotai Island, Indonesia, documenting the types and quantities of litter including plastics at a macro scale.
Preliminary Assessment of Plastic Litter and Microplastic Contamination in Freshwater Depositional Areas: The Case Study of Puerto Misahualli, Ecuadorian Amazonia
Researchers conducted a preliminary assessment of plastic litter and microplastics in sediments at a riverine depositional area in the Ecuadorian Amazon, finding low-density polyethylene bags as the dominant macroplastic and documenting microplastic presence in an upper Amazon basin location.
Differential Presence of Microplastics and Mesoplastics in Coral Reef and Mangrove Fishes in Isla Grande, Colombia
Researchers found that fish from mangrove ecosystems in the Colombian Caribbean contained higher levels of microplastics and mesoplastics than fish from coral reef environments, suggesting that habitat type significantly influences plastic ingestion rates in marine fish species.
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.
The impact of tourism on marine litter pollution on Santa Marta beaches, Colombian Caribbean
Tourism significantly increased litter pollution on beaches in Santa Marta, Colombia, with plastics making up 30-77% of macroplastic waste and microplastics ranging from 1 to 355 items per square meter during peak tourist season. Local residents identified tourism as the primary source, highlighting the need for better waste management and public education at coastal destinations.
Impact of mangrove forest structure and landscape on macroplastics capture
Researchers surveyed macroplastic accumulation across seven mangrove forests in the Philippines, finding 1.1 items per square meter on average with the highest abundance at landward zones and near river mouths. Mangrove biomass and root structure were positively correlated with plastic capture, confirming that mangrove structural complexity enhances their ability to trap land-derived plastic litter.
Coastal populations and river discharges as sources of microplastic pollution of the Ciénaga Grande de Santa Marta, Colombian Caribbean
Researchers investigated microplastic contamination in surface waters of the Ciénaga Grande de Santa Marta coastal lagoon in Colombia and assessed the contribution of coastal populations and river discharges as pollution sources. MPs were detected throughout this internationally protected Ramsar site, with proximity to populated areas and river inputs driving spatial variation in contamination.
Composition and Density of Macro Marine Debris in the Mangrove Area of Keramat Village Mananggu Sub-district Boalemo Regency
Researchers assessed the composition and density of macro marine debris in a mangrove area of Boalemo Regency, Indonesia. Plastic waste was the predominant debris type, posing a threat to the mangrove ecosystem and its biodiversity. The study provides baseline data for monitoring and managing marine debris in coastal Indonesian communities.
Size and Types Distribution of Marine Debris in the Mangrove Ecosystem of Bintan Island - Indonesia
Researchers surveyed marine debris — from large items to microplastics — in sediments and gastropods in mangrove ecosystems on Bintan Island, Indonesia. Both macro and microplastics were found throughout the mangrove environment, including in the tissues of marine snails, indicating that mangrove ecosystems serve as sinks for plastic pollution.
Spatial distribution of marine debris in mangrove ecosystem of Pantai Indah Kapuk, Jakarta
Researchers surveyed marine debris in the mangrove ecosystem of Pantai Indah Kapuk in Jakarta, finding that plastic items made up 77.7% of all macro debris followed by styrofoam at 18.1%. Microplastics were also assessed in sediments, establishing baseline contamination data for this urban mangrove system.

Fish from Colombia's Luruaco Lagoon contained microplastics with prevalence, abundance, and polymer characteristics analyzed across four sampling events, with principal component analysis linking MP types to feeding ecology and habitat use of the different species.
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 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.
