A team of researchers from the University of Manitoba has developed a quantitative tracer technique that can be used to measure the bioaccumulation of nanoplastics in freshwater environments. This method, which relies on fluorescence tagging, is a significant step forward in understanding the impacts of microplastics on aquatic ecosystems. With this technique, researchers can measure the buildup of nanoplastics in both water and living organisms, providing a more comprehensive view of the potential risk posed by microplastics. This information is critical in developing sustainable management strategies to protect freshwater ecosystems.
