Microplastics in the Estuarine Area of the Pineios River: Seasonal Trends and Variability

This study examines the concentration and distribution of microplastics in the estuary area of the Pineios River. The results show a clear seasonal pattern, with much higher microplastic levels during the summer. The difference in the shape distribution between sediment and water samples shows that human activities and the physical and chemical properties of microplastics affect where they end up in the environment.
