Microplastic consumption by fish and bivalve in río negro, uruguay

Summary

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.
