Management and research on plastic debris in Uruguayan Aquatic Systems: update and perspectives
AI summary Read the abstract
This review summarizes research on plastic debris in Uruguay's rivers, estuaries, and coastal waters, identifying knowledge gaps and calling for improved waste management and public awareness. It documents that plastic pollution affects both freshwater and marine ecosystems in the region and highlights the need for coordinated South American research and policy responses.
Synthetic plastics have become an indispensable component of modern life, and the amount of plastics disposal has increased dramatically as a result. With human population increasing, it is expected that the prevalence of plastic debris in the environment will also increase, unless sustainable daily habits are incorporated, waste management improved, and new alternative materials are discovered and popularized. To date, several reports show negative effects of plastic debris on marine and freshwater fauna (e.g. invertebrates, birds, turtles, marine mammals).

Microplastic consumption by fish and bivalve in río negro, uruguay
AI summary Read the abstract
Fish and bivalves collected from the Río Negro in Uruguay were found to contain microplastics in their digestive systems, indicating that freshwater organisms in South American rivers are ingesting plastic particles. The contamination was present across multiple species, suggesting widespread environmental exposure in this river system. These findings are relevant to food safety since both fish and bivalves are consumed by local human populations.

Plastic Interactions with Brazilian Aquatic Organisms: A Systematic Review of Research Trends and Knowledge Gaps
AI summary Read the abstract
This systematic review summarizes research on how plastic pollution interacts with aquatic organisms across Brazil's rivers, coasts, and oceans. It identifies major knowledge gaps, including limited studies on microplastic effects in freshwater species and a lack of standardized methods. Understanding these interactions matters because contaminated fish and shellfish can carry microplastics into the human food chain.
