Polystyrene Nanoplastics Adversely Affect Chick Embryos

According to a March 2023 Environment International article https://doi.org/10.1016/j.envint.2023.107865 and at https://weather.com/en-IN/india/health/news/2023-03-20-nanoplastics-disrupt-heart-nervous-system-growth-in-chick-embryo by researchers with Netherlands Leiden University and others “… We have investigated how the size and dose of polystyrene nanoparticles affects malformations in chicken embryos … We find that nanoplastics can cross the embryonic gut wall. When injected into the vitelline vein, nanoplastics become distributed in the circulation to multiple organs. We find that the exposure of embryos to polystyrene nanoparticles produces malformations that are far more serious and extensive than has been previously reported … We show that the mechanism of toxicity is the selective binding of polystyrene nanoplastics nanoparticles to neural crest cells, leading to the death and impaired migration of those cells … These results are a matter of concern given the large and growing burden of nanoplastics in the environment. Our findings suggest that nanoplastics may pose a health risk to the developing embryo …” #PlasticWaste #SingleUsePlastic #NanoPlastics @UniLeidenNews
