[Exposure Pathways of Polystyrene Nanoplastics Mediate Their Cellular Distribution and Toxicity].
Summary
This study found that the route by which polystyrene nanoplastics enter the body determines which liver cell types accumulate the particles and what toxic effects occur, demonstrating that exposure pathway—not just dose—shapes nanoplastic toxicity in hepatic tissue.
Exposure pathways mediate the hepatic cell-type-specific distribution of PSNPs, thereby altering the downstream toxicological consequences induced by exposure to PSNPs.

Integrative lipidomic and transcriptomic analysis unraveled polystyrene nanoplastics-induced liver injury via oral and inhalation exposure: All roads lead to Rome?
Researchers exposed mice to polystyrene nanoplastics through both oral ingestion and inhalation, and found that both routes caused liver damage but through different molecular pathways. Oral exposure mainly caused visible tissue damage, while inhaled nanoplastics triggered more severe inflammation and impaired the liver's ability to produce essential proteins. The study reveals that breathing in nanoplastics may be just as harmful to the liver as swallowing them, with different but equally concerning effects.
Effects of polystyrene micro/nanoplastics on liver cells based on particle size, surface functionalization, concentration and exposure period
Researchers systematically studied the effects of polystyrene micro- and nanoplastics on human liver cells, varying particle size, surface chemistry, concentration, and exposure duration. They found that smaller particles were internalized more readily and that surface functionalization significantly influenced toxicity, with aminated particles causing the most cell damage. The study suggests that particle characteristics beyond just size play an important role in determining how micro- and nanoplastics affect human cells.
Biological interactions of polystyrene nanoplastics: Their cytotoxic and immunotoxic effects on the hepatic and enteric systems
Researchers exposed mouse and human liver cells and live mice to polystyrene nanoplastics of five different sizes and found that the smallest particles were most toxic in lab dishes, while medium and large particles caused the most liver damage in living animals. The larger particles triggered immune responses by recruiting inflammatory cells to the liver and intestines, causing tissue damage. This study reveals that nanoplastic size matters in unexpected ways, and that lab tests alone may not predict which particles are most dangerous in the body.
Analysis of Biodistribution and in vivo Toxicity of Varying Sized Polystyrene Micro and Nanoplastics in Mice
This study found that smaller plastic particles spread more widely through the bodies of mice and caused more organ damage than larger ones, particularly in the liver, kidneys, and heart. Nanoplastics (under 1 micrometer) were especially concerning because they crossed biological barriers more easily than microplastics. The results suggest that the tiniest plastic particles in our environment may pose the greatest health risks.
Tissue distribution of polystyrene nanoplastics in mice and their entry, transport, and cytotoxicity to GES-1 cells
Scientists tracked polystyrene nanoplastics in mice after oral exposure and found the particles accumulated in the stomach, intestines, and liver tissues. In human gastric cells, the nanoplastics entered through multiple pathways and were transported through the cell's internal trafficking system, ultimately reducing cell growth and increasing cell death. The study provides detailed evidence of how nanoplastics can cross biological barriers and cause cellular damage in mammalian systems.
