ClearMethods 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.
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 commercially important and invasive fish species along the Colombian Caribbean coast and San Andrés Island, examining the relationship between microplastic distribution and species ecology and geography.
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.
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.
Pervasive Microplastic Ingestion by Commercial Fish Species from a Natural Lagoon Environment
Researchers examined microplastic contamination in the gastrointestinal tracts and gills of commercial fish species from a natural lagoon environment. Microplastics were found across all species examined, with fiber morphotypes dominant and contamination levels reflecting the lagoon's proximity to human activity and plastic pollution sources.
Occurrence of microplastics in the gastrointestinal tract of Amazonian fish species with different feeding habits
Microplastics were found in the gastrointestinal tracts of multiple Amazonian fish species with different feeding habits from Lake Janauacá and the Anavilhanas Archipelago, with feeding strategy influencing ingestion rates—underscoring widespread microplastic contamination even in remote Amazon basin aquatic ecosystems.
Identification, Abundance, and Distribution of Microplastics in Surface Water Collected from Luruaco Lake, Low Basin Magdalena River, Colombia
Researchers documented microplastic contamination in Luruaco Lake, Colombia, for the first time, assessing the identification, abundance, and seasonal distribution of microplastic particles in surface waters of this important Magdalena River basin lake.
Impact of contamination due to ingestion of microplastics on commercial fish in relation to their trophic habits
Researchers evaluated the ingestion of microplastics by 28 Sciaenidae and 12 Ariidae fish species from estuaries in Tumaco and Buenaventura Bay, Colombia, examining stomach contents of 1,652 specimens across high and low precipitation seasons in 2020-2021 and analyzing how trophic level and other biological characteristics influence microplastic uptake.
Occurrence and characterization of microplastic content in the digestive system of riverine fishes
Researchers found microplastics in 93.8% of riverine fish examined, with polystyrene, polyethylene, and nylon being the most common polymer types concentrated near urban and industrial areas, and small particles (0.025-1 mm) predominating across 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.
Occurrence of microplastics in commercial fish from a natural estuarine environment
Researchers examined the gastrointestinal tracts of commercial fish caught from a natural estuarine environment and found microplastics in a significant proportion of individuals, documenting both occurrence rates and particle characteristics.
Identification of the composition and abundance of microplastics in the digestive tract of fish in the Banjaran River, Banyumas District
Researchers identified and quantified microplastic composition and abundance in digestive tract contents of wild-caught fish from a coastal fishery, documenting ingestion rates, polymer types, and particle morphologies across multiple commercially important species.
Microplastic contamination in bivalves: First assessment in three coastal lagoons of the colombian caribbean, south america
Researchers assessed microplastic contamination in bivalves from three coastal lagoons, finding that filter-feeding species readily accumulate particles from surrounding water and sediment. The study characterized particle types and polymer compositions across different lagoon environments.
Microplastics in fishes in amazon riverine beaches: Influence of feeding mode and distance to urban settlements
Researchers found microplastics in the digestive tracts of 29 fish species from Amazon riverine beaches, with contamination levels influenced by fish feeding mode and distance to urban settlements within a protected area.
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.
Effect of biological and environmental factors on microplastic ingestion of commercial fish species
Researchers analyzed microplastic ingestion in commercially important fish species, evaluating how biological and environmental factors influence ingestion rates across 2,222 individual fish. The study assessed gastrointestinal tract contents to determine the extent and patterns of microplastic contamination. The findings suggest that both species-specific biology and environmental conditions play important roles in determining microplastic ingestion levels in commercial fish.
Abundance and Characteristics of Microplastics Found in The Gastrointestinal Tract of Commercial Marine Fish from Bitung, North Sulawesi, Indonesia
Researchers analyzed microplastic abundance and characteristics in the gastrointestinal tracts of commercial marine fish from Bitung, North Sulawesi, Indonesia, providing the first data on seafood microplastic contamination from one of the country's major fisheries production centers.
Abundance, characteristics and variation of microplastics in different freshwater fish species from Bangladesh
Researchers examined 48 freshwater fish from 18 species in Bangladesh and found microplastics in the digestive tracts of over 73% of the fish studied. Fibers were the most common shape, and the plastics were primarily polyethylene and polypropylene-based polymers. Bottom-dwelling fish contained more microplastics than those living higher in the water column, suggesting that contaminated sediments are a significant source of exposure for freshwater species.
Abundance and Characteristics of Microplastics Found in The Gastrointestinal Tract of Commercial Marine Fish from Bitung, North Sulawesi – Indonesia
Researchers analyzed microplastic abundance and characteristics in the gastrointestinal tracts of commercial marine fish from Bitung, North Sulawesi, Indonesia, providing baseline contamination data for commercially important species from a major Indonesian fisheries region.
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.
