Unfolding the interaction of radioactive Cs and Sr with polyethylene-derived microplastics in marine environment
Researchers investigated how polyethylene microplastics in the marine environment interact with radioactive cesium and strontium. They found that as microplastics age in seawater and develop biofilms, their ability to absorb these radioactive elements increases significantly. The study provides evidence that microplastics could act as previously unrecognized carriers of radioactive contamination in ocean environments.

Insights into Tissue-Specific Bioaccumulation of Nanoplastics in Marine Medaka as Revealed by a Stable Carbon Isotopic Approach
Using fluorescently labeled nanoplastics, researchers tracked tissue-specific accumulation of these tiny particles in marine medaka fish, finding that nanoplastics concentrated in particular organs and persisted over time. Because nanoplastics are so small they can cross biological barriers, understanding exactly where they accumulate in fish bodies helps assess the risk they pose to both marine life and to humans who consume seafood.
