Additional file 1 of Unfolding the interaction of radioactive Cs and Sr with polyethylene-derived microplastics in marine environment
This supplementary file provides additional data from a study examining the interaction of radioactive caesium and strontium with polyethylene-derived microplastics in the marine environment.
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.
Unfolding the interaction of radioactive Cs and Sr with polyethylene-derived microplastics in marine environment
A mesocosm study examined how radioactive cesium and strontium interact with pristine, radiation-exposed, and marine-weathered polyethylene microplastics, finding that environmental aging—through biofilm formation and surface roughening—significantly increased the plastic particles' capacity to sorb radioactive contaminants.
Initial data on adsorption of Cs and Sr to the surfaces of microplastics with biofilm
Researchers measured adsorption of radiocesium and radiostrontium onto weathered microplastics deployed in freshwater, estuarine, and marine environments, finding that distribution coefficients were approximately two to three orders of magnitude lower than for sediment reference values. Despite the lower adsorption, the buoyancy and mobility of plastics suggest they may still function as a significant radionuclide reservoir in aquatic systems.
Biofilm-enhanced adsorption of strong and weak cations onto different microplastic sample types: Use of spectroscopy, microscopy and radiotracer methods
Researchers used radiotracer, spectroscopy, and microscopy methods to show that biofilm-coated environmental plastics adsorb radioactive cesium and strontium — radionuclides associated with nuclear releases — though at rates much lower than natural sediments, confirming that plastics act as a minor but measurable sink for environmental radioactivity.
