A new study from Pusan National University, South Korea, has revealed that PS nanoparticles, commonly used in packaging, can affect red blood cell (RBC) development in zebrafish embryos, suggesting potential ecological risks associated with nanoplastics. The findings, published in Zoological Research, highlight the previously unknown effects of PS nanoparticles on blood cell development. The researchers discovered that nanoparticle exposure alters RBC maturation, leading to an increase in immature cells and a reduction in mature RBCs.
