ClearPalliative potential of robinetin to avert polystyrene microplastics instigated pulmonary toxicity in rats
Researchers investigated whether the flavonoid compound robinetin could protect against lung damage caused by polystyrene microplastic exposure in rats. They found that robinetin supplementation reduced oxidative stress markers and inflammatory responses in lung tissue that had been damaged by microplastic ingestion. The study suggests that certain natural compounds may help mitigate some of the harmful effects of microplastic exposure on respiratory tissues.
Mechanism of S-Palmitoylation in Polystyrene Nanoplastics-Induced Macrophage Cuproptosis Contributing to Emphysema through Alveolar Epithelial Cell Pyroptosis
Researchers found that breathing in polystyrene nanoplastics caused emphysema (a type of lung disease) in rats by triggering a chain reaction: the nanoplastics entered immune cells in the lungs, caused copper-related cell death in those immune cells, which then released inflammatory signals that destroyed the air sacs. This newly discovered mechanism shows how inhaled nanoplastics could contribute to serious, irreversible lung damage.
Microplastics and Nanoplastics Impair the Biophysical Function of Pulmonary Surfactant by Forming Heteroaggregates at the Alveolar–Capillary Interface
Scientists found that micro and nanoplastics from common products like foam packaging, lunch boxes, and water bottles can impair the function of pulmonary surfactant, the crucial substance that keeps our lungs from collapsing. Polystyrene foam particles caused the most damage, both in lab tests and in mice, where they triggered lung inflammation. The nanoplastic fraction, though a small part of the total mass, appeared to drive most of the harm by forming clumps with the surfactant at the air-liquid surface in the lungs.
Polystyrene microplastic induced airway hyper-responsiveness, and pulmonary inflammation are mitigated by bronchom treatment in murine model of lung disease
Researchers exposed mice to polystyrene microplastics and found that the particles triggered airway hyper-responsiveness, lung inflammation, and structural damage similar to asthma-like symptoms. An herbal medicine called Bronchom, given as a pre-treatment, significantly reduced these harmful effects by lowering inflammatory cell counts and cytokine levels in the lungs. The study suggests that microplastic inhalation can cause meaningful respiratory problems and identifies a potential natural approach for mitigating lung inflammation caused by microplastic exposure.
Deleterious effects of microplastics and nanoplastics on rodent lungs: a systematic review
This systematic review summarizes research on how inhaled micro- and nanoplastics affect the lungs in animal studies. The findings show these particles can cause lung inflammation, tissue damage, and immune responses, suggesting that breathing in airborne microplastics may pose real risks to respiratory health.
Investigation of pulmonary toxicity evaluation on mice exposed to polystyrene nanoplastics: The potential protective role of the antioxidant N-acetylcysteine
Researchers investigated lung damage in mice exposed to inhaled polystyrene nanoplastics and tested whether the antioxidant N-acetylcysteine could offer protection. They found that nanoplastics caused significant lung inflammation, tissue damage, and oxidative stress, but N-acetylcysteine treatment helped reduce these harmful effects. The study suggests that oxidative stress is a key mechanism behind nanoplastic-induced lung injury and points to potential protective strategies.
Unveiling the Pulmonary Toxicity of Polystyrene Nanoplastics: A Hierarchical Oxidative Stress Mechanism Driving Acute–Subacute Lung Injury
Researchers investigated the pulmonary toxicity of polystyrene nanoplastics smaller than 100 nm in lung epithelial cells and macrophages, finding that exposure triggered a hierarchical oxidative stress mechanism that drove acute to subacute lung injury through lipid peroxidation and inflammation.
Quercetin intervention mitigates small intestinal damage and immunologic derangement induced by polystyrene nanoplastics: Insights from multi-omics analysis in mice
Researchers found that quercetin, a natural compound found in fruits and vegetables, protected mice from gut damage and immune system disruption caused by polystyrene nanoplastics. The nanoplastics damaged the small intestine and disrupted immune balance, but quercetin reversed much of this harm by restoring healthy gut bacteria and gene activity. This suggests that dietary compounds like quercetin might help counteract some negative health effects of nanoplastic exposure.
Exposure to polystyrene microplastics triggers lung injury via targeting toll-like receptor 2 and activation of the NF-κB signal in mice
This mouse study found that inhaling polystyrene microplastics caused serious lung damage, including inflammation, cell death, and scar tissue buildup. Smaller microplastics (1-5 micrometers) caused more harm than larger ones, and the damage worsened with longer exposure. The study identified a specific immune pathway (TLR2/NF-kB) through which inhaled microplastics trigger lung injury, raising concerns about the respiratory effects of airborne microplastics on humans.
Protective effect of curcumin against microplastic and nanoplastics toxicity
Researchers reviewed studies examining whether curcumin, the active compound in turmeric, can protect against the toxic effects of micro- and nanoplastics in the body. Evidence indicates that curcumin helped reduce oxidative stress, inflammation, and organ damage caused by plastic particle exposure across multiple organ systems in animal studies. The review suggests that natural antioxidant compounds like curcumin may hold promise for mitigating some of the harmful effects of plastic pollution on health.
Repeated inhalation exposure to polystyrene nanoplastics induced sustained pulmonary injury and fibrosis in mice.
Scientists exposed mice to tiny plastic particles found in air pollution and discovered these particles caused serious lung damage and scarring that didn't heal even weeks after exposure stopped. The smallest plastic particles were the most harmful, spreading from the lungs to other organs like the heart and liver. This research suggests that breathing in nanoplastics from everyday sources like car tire wear and plastic waste could pose long-term risks to human lung health.
Potential health risks of the interaction of microplastics and lung surfactant
Researchers investigated how polystyrene microplastics interact with lung surfactant extracted from porcine lungs. The study found that microplastics altered the surface tension and membrane structure of lung surfactant, preferentially adsorbed phospholipid components, and accelerated the production of reactive oxygen species, suggesting potential risks to respiratory health from inhaled microplastics.
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.
Baicalein Inhibited Amino‐modified Polystyrene Nanoplastics Induced Human Umbilical Vein Endothelial Cells Pyroptosis by Reducing the Expression of NLRP3/Caspase‐1/Gasdermin D Pathway‐related Proteins
Researchers tested whether baicalein, a natural plant compound with anti-inflammatory properties, could protect blood vessel cells from damage caused by nanoplastics. They found that baicalein significantly reduced the inflammatory cell death triggered by amino-modified polystyrene nanoplastics by blocking a key inflammatory pathway. The study suggests that natural anti-inflammatory compounds may help mitigate some of the vascular damage associated with nanoplastic exposure.
Effects of polystyrene microplastics on mice cardiac tissue structure: Protective role of resveratrol
Researchers exposed mice to polystyrene microplastics for 90 days and found that the particles caused significant oxidative stress and structural damage to heart tissue. However, when mice also received resveratrol, a natural antioxidant compound found in grapes and berries, much of the cardiac damage was prevented. The study suggests that antioxidant compounds may offer some protective benefit against microplastic-induced heart tissue damage.

Sakuranetin counteracts polyethylene microplastics induced nephrotoxic effects via modulation of Nrf2/Keap1 pathway
Researchers found that polyethylene microplastics caused kidney damage in rats by increasing oxidative stress and disrupting a key protective cellular pathway. However, when the natural plant compound sakuranetin was administered alongside the microplastics, it significantly reduced the kidney damage by restoring antioxidant defenses. The study suggests that certain natural compounds may help counteract some of the harmful effects of microplastic exposure on organ health.

Researchers compared the lung toxicity of microplastics and nanoplastics made from polystyrene, polyethylene, and polypropylene in mice and human lung cells. They found that all particle types induced signs of pulmonary fibrosis, inflammation, and tissue remodeling, with polystyrene nanoplastics causing the most severe effects. The study suggests that smaller nanoplastic particles and certain polymer types may pose greater risks to lung health.

Researchers investigated the size-dependent toxicity of polystyrene microplastics in lung cells using both mouse and cell culture models. The study found that smaller 1-micrometer particles accumulated more in lung tissue than larger particles and identified epithelial-mesenchymal transition as a key toxic mechanism, driven by ECM-MMP signaling cascades that contribute to lung injury.
Integrative Analysis of Pharmacology and Transcriptomics Predicts Resveratrol Will Ameliorate Microplastics-Induced Lung Damage by Targeting Ccl2 and Esr1
Researchers used pharmacology network analysis and transcriptomics to predict that resveratrol may help mitigate lung damage caused by microplastic exposure. They identified two key molecular targets, Ccl2 and Esr1, through which resveratrol could exert protective effects. The study offers a new perspective on potential approaches to addressing microplastic-induced lung injury, though further experimental validation is needed.
Harmful effects of true-to-life nanoplastics derived from PET water bottles in human alveolar macrophages.
Researchers tested nanoplastics derived from actual PET water bottles on mouse lung immune cells, focusing specifically on cells that had internalized the particles. Even though the nanoplastics were taken up by 100% of cells at the highest dose, they did not cause outright cell death. However, they did trigger significant increases in reactive oxygen species and shifted the immune cells toward a pro-inflammatory state, suggesting that inhaled nanoplastics from everyday plastic products could promote chronic lung inflammation.
Microplastics and Nanoplastics as Environmental Contaminants of Emerging Concern: Potential Hazards for Human Health
This review covers how microplastics and nanoplastics enter humans through food, air, and skin contact, accumulating in the body over time. Inhaled particles can damage the lungs from the upper airways down to the deepest air sacs, and prolonged exposure has been linked to chronic inflammation, autoimmune disease, atherosclerosis, and cancer. The authors call for source reduction, material substitution, and better filtration to reduce exposure.
Pulmonary hazards of nanoplastic particles: a study using polystyrene in in vitro models of the alveolar and bronchial epithelium
Lab tests on human lung cell models found that polystyrene nanoplastics did not cause immediate cell death but did interfere with key lung functions like surfactant and mucus production and immune signaling. This means standard toxicity tests may underestimate the real danger of inhaling nanoplastics, and researchers need to look beyond simple cell survival to understand the true health effects on the lungs.
