Cytotoxicity and Genotoxicity of Polystyrene Micro- and Nanoplastics with Different Size and Surface Modification in A549 Cells
Summary
Researchers tested polystyrene micro- and nanoplastics of different sizes and surface modifications on human lung cells to evaluate their potential toxicity. They found that particle size, surface chemistry, and how particles interact with surrounding biological fluids all significantly influenced cellular damage and DNA harm. The study highlights that the toxicity of plastic particles in humans depends on multiple physical and chemical properties, not just their presence.
This study shows that the intrinsic size properties and surface modification of PS plastics, the interaction between PS plastics and the receiving medium, intracellular accumulation are critical factors for evaluating the toxicological influences of PS plastics on humans.

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.
Polystyrene microplastic particles: In vitro pulmonary toxicity assessment
Researchers tested the effects of polystyrene microplastics on human lung cells in the laboratory and found that the particles triggered inflammation and oxidative stress. The microplastics also weakened the protective barrier function of lung tissue by depleting key structural proteins. The study suggests that inhaling microplastics may increase the risk of respiratory problems by damaging the lung's natural defenses.
A549 as an In Vitro Model to Evaluate the Impact of Microplastics in the Air
This review examines studies using human lung cells grown in the lab to understand how airborne microplastics may affect the respiratory system. Researchers found that polystyrene micro- and nanoplastics can trigger inflammation, DNA damage, oxidative stress, and cell death in lung tissue. The evidence indicates that inhaled microplastics may pose meaningful risks to respiratory health, though more research is needed on real-world exposure levels.
Cytotoxic effects of polystyrene nanoplastics with different surface functionalization on human HepG2 cells
Researchers exposed human liver (HepG2) cells to 50 nm polystyrene nanoparticles with three different surface chemistries and found that amino-functionalized particles caused the greatest cytotoxicity and oxidative stress, demonstrating that surface charge and chemistry — not just particle size — determine nanoplastic harm to human cells.
Are all nanoplastics equally neurotoxic? Influence of size and surface functionalization on the toxicity of polystyrene nanoplastics in human neuronal cells
Researchers tested four types of polystyrene nanoplastics on human neuronal cells and found that toxicity varied dramatically depending on particle surface chemistry. Particles with amine surface groups were the most harmful, significantly reducing cell survival and causing visible damage to cell structures, while unmodified particles showed minimal toxicity, suggesting that surface properties matter as much as size when assessing nanoplastic risks.
