Plastic pollution in freshwater ecosystems: macro-, meso-, and microplastic debris in a floodplain lake
Researchers surveyed macro-, meso-, and microplastic debris in a South American floodplain lake and found an average of 704 microplastic particles per square meter in sediments, with plastic contamination comparable to marine beaches — demonstrating that freshwater lakes can be major plastic pollution reservoirs.
Detection of plastics particles in equine blood by Scanning Electron Microscopy
Researchers used scanning electron microscopy to detect plastic particles in equine blood samples, providing the first evidence of circulating microplastics in horses and demonstrating a method for detecting plastic particles in veterinary blood specimens.
Microplastics contamination in commercial fish meal and feed: a major concern in the cultured organisms
Researchers analyzed commercial fish meal and animal feed samples and found microplastics in all of them, with fish meal containing up to 1,154 particles per kilogram. The contaminated feed is given to farmed fish, shrimp, and chicken, creating a pathway for microplastics to reach humans through the food supply. Feed made from dried fish had higher contamination levels than feed from fresh fish, and the microplastics also carried toxic heavy metals.
Preliminary Assessment of Plastic Litter and Microplastic Contamination in Freshwater Depositional Areas: The Case Study of Puerto Misahualli, Ecuadorian Amazonia
Researchers conducted a preliminary assessment of plastic litter and microplastics in sediments at a riverine depositional area in the Ecuadorian Amazon, finding low-density polyethylene bags as the dominant macroplastic and documenting microplastic presence in an upper Amazon basin location.
