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.
Methods to characterize microplastics: case study on freshwater fishes from a tropical lagoon in Colombia
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.
Dinámica temporal de los hábitos tróficos e incidencia de microplásticos en bagres (Ariidae) en la bahía de Buenaventura, Pacífico colombiano
Four species of catfish in Colombia's Buenaventura Bay were found to have ingested microplastics, with rates of 9–13% across species and higher ingestion in adults during the rainy season. The finding that commercially harvested fish in a bay heavily used for artisanal fishing contain microplastics raises direct food safety concerns for the coastal communities that depend on these species as a primary protein source.
Microplastic abundance in three commercial fish from the coast of Lima, Peru
Researchers found microplastics in the stomachs and intestines of three commercially important fish species caught off the coast of Lima, Peru. The results confirm that microplastic ingestion is widespread among fish commonly consumed by humans in South American coastal communities.
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.
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.
