Aquatic ecosystems are suffering from various human-induced issues, with plastic pollution being a significant threat, particularly in Colombia's Luruaco Lagoon, where streams discharge microplastics (MPs) from urban areas.
Researchers conducted four sampling trips, capturing fish with trawl nets and examining their gastrointestinal tracts to assess the presence and characteristics of MPs.
Out of 271 fish from seven species studied, microplastics were found in all, totaling 1,157 particles, with a notable prevalence linked to dietary habits, especially in specific species like Mugil liza and Andinoacara latifrons.
