Weathered Microplastics found to be more Toxic to Mice than Virgin Microplastics

According to the abstract of a September 15, 2023 Environmental Research article by researchers with Kyungpook National University, Republic of Korea (RoK) and other RoK research institutions “… The growing use of plastic materials has resulted in a constant increase in the risk associated with microplastics (MPs). Ultra-violet (UV) light and wind break down modify MPs in the environment into smaller particles known as weathered MPs (WMPs) and these processes increase the risk of MP toxicity. The neurotoxicity of weathered polystyrene-MPs remains unclear …  WMP and virgin MPs (VMPs) were orally administered … male mice … results show that WMP is a more profound inflammatory factor than VMP. In summary, our findings demonstrate the toxicity of WMPs and provide theoretical insights into their potential risks to biological systems and even humans in the ecosystem …” #PlasticWaste #SingleUsePlastic #FoodPackaging #MicroPlastics @knustory
