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.
Impacts of marine debris contamination in the mangrove ecosystem of the Ciénaga Grande de Santa Marta, Colombian Caribbean

Mangroves are important coastal filters but are being overwhelmed by plastic inputs.
Rural village as a source of microplastic pollution in a riverine and marine ecosystem of the southern Venezuelan Caribbean
Researchers quantified microplastic pollution in a rural Venezuelan Caribbean coastal community (Chichiriviche de la Costa) and its adjacent riverine and marine environment across dry and rainy seasons. MPs were detected in river water and sediment, marine water, sediment, fish, and sponges, demonstrating that even low-population rural settlements contribute meaningful MP loading to downstream ecosystems.
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.
Invisible Footprints: Exploring Microplastic Pollution in the Colombian Caribbean Sea
Researchers documented microplastic contamination throughout the surface and mid-waters of the Colombian Caribbean, detecting plastic particles in every single water sample collected across 16 stations in two departments. Concentrations were higher near the coast and in areas with strong river influence, with fibers and fragments of PET and polypropylene most common, and several rare high-risk polymers also detected. As one of the first systematic studies of its kind in this region, the work establishes baseline data for a relatively understudied stretch of the Caribbean and identifies urban river inputs as a key contamination driver.
Quantifying fluxes of microplastics from the magdalena river into the caribbean sea
This study quantified how many microplastics the Magdalena River — Colombia's largest river — carries into the Caribbean Sea, establishing a baseline for understanding South America's contribution to marine plastic pollution. River-to-ocean flux measurements like this are essential for building accurate global models of how plastic pollution accumulates in marine ecosystems.
Microplastics in water and fish of commercial interest: Distribution and relation to ecology in the colombians caribbean region, south america
