Polystyrene nanoplastics induce oxidative stress in Aurelia coerulea polyps, microglia, and mice
Summary
Researchers tested the effects of polystyrene nanoplastics across three very different biological systems: jellyfish polyps, brain immune cells, and mice. Despite the different organisms, all three showed consistent oxidative stress responses when exposed to the nanoplastics. The converging evidence across marine, cellular, and mammalian models highlights the widespread biological risks these tiny plastic particles may pose.
While these models represent distinct organisms and biological contexts, all demonstrated consistent oxidative stress responses upon PS-NPs exposure. Although we do not claim direct equivalency across species, the converging evidence from marine, cellular, and mammalian systems highlights the widespread biological risks posed by nanoplastics. These findings provide a foundation for evaluating environmental and public health threats associated with PS-NPs.
