ClearThe nephrotoxic potential of polystyrene microplastics at realistic environmental concentrations
Researchers tested polystyrene microplastics on human kidney cells at concentrations reflecting real-world environmental levels. They found that the particles attached to and were engulfed by the cells, triggering oxidative stress and inflammatory responses that reduced cell survival. The findings suggest that even realistic low-level microplastic exposure may pose risks to kidney health.
Adverse effect of polystyrene microplastics (PS-MPs) on tube formation and viability of human umbilical vein endothelial cells
Researchers tested the effects of polystyrene microplastics on human blood vessel cells grown in the laboratory and found that the particles reduced cell survival and inhibited the formation of new blood vessel structures. Smaller microplastics accumulated inside the cells more readily and triggered cell death through autophagy and necrosis. The study suggests that microplastics entering the bloodstream could potentially interfere with normal vascular function.
Toxicity of polystyrene nanoplastics to human embryonic kidney cells and human normal liver cells: Effect of particle size and Pb2+ enrichment
Researchers tested polystyrene nanoplastics on human kidney and liver cells and found that particles smaller than 100 nanometers caused significant cell death, with kidney cells being more vulnerable. When nanoplastics carried lead contamination from water, their toxicity increased further. The study suggests that while nanoplastics alone in drinking water may pose limited risk, their ability to concentrate heavy metals is a serious concern.

The findings suggest that microplastics reaching internal organs could have measurable effects at the cellular level.

Researchers compared the effects of polystyrene nanoplastics on primary human umbilical vein endothelial cells (HUVEC) and immortalized endothelial cells (hy926) to understand how vascular endothelium responds after nanoplastics cross the epithelial barrier. The study assessed oxidative stress and ROS generation to characterize how cell line type influences nanoplastic toxicity responses.
Nanoplastic toxicity and uptake in kidney cells: differential effects of concentration, particle size, and polymer type
Researchers exposed human kidney proximal tubule cells to nanoplastics of different polymer types, sizes, and concentrations to assess short-term toxic effects. They found that polystyrene and PMMA nanoparticles were readily internalized by kidney cells and caused concentration-dependent reductions in cell viability and changes in cell cycle distribution. The study suggests that nanoplastics can directly affect kidney cell function, with toxicity varying by polymer type and particle size.
Polystyrene nanoplastics induce apoptosis of human kidney proximal tubular epithelial cells via oxidative stress and MAPK signaling pathways
Researchers found that polystyrene nanoplastics cause programmed cell death in human kidney tubular cells through oxidative stress and activation of the MAPK signaling pathway. The toxic effects were dependent on both the size and dose of the nanoplastics, with smaller particles causing more damage. The study identifies specific molecular mechanisms by which nanoplastics may contribute to kidney cell injury.
Polystyrene nanoparticles induce DNA damage and apoptosis in HeLa cells
Researchers exposed human HeLa cells to polystyrene nanoplastics — particles smaller than 100 nm — and found that even short exposures at low concentrations caused DNA damage, abnormal cell division, and signs of cell death including apoptosis and necrosis. The results suggest nanoplastics can directly damage human cell DNA, raising concerns about the health implications of everyday nanoplastic exposure.

Researchers exposed human breast cancer cells and normal skin cells to polystyrene nanoplastics and found that smaller particles at higher concentrations caused significant cell death through apoptosis (programmed cell death) and reduced the cells' ability to defend against oxidative damage. The dose- and size-dependent toxicity suggests that nanoplastics small enough to enter cells are more biologically harmful than larger particles.

This study found that polystyrene microplastics caused damage to human kidney cells in the lab and accumulated in the kidneys of mice.

Hazard assessment of different-sized polystyrene nanoplastics in hematopoietic human cell lines
Researchers tested how different sizes of polystyrene nanoplastics (50, 200, and 500 nm) affect human blood cell lines. While none of the sizes caused direct cell death, all three were taken up by cells and disrupted mitochondrial function in immune-related cell types. The study suggests that even without killing cells outright, nanoplastics may interfere with important cellular energy processes, with effects varying by particle size and cell type.
