ClearEffects of polystyrene nanoplastic gestational exposure on mice
Researchers exposed pregnant mice to airborne polystyrene nanoplastics and studied the effects on both mothers and offspring. High-dose exposure caused fatty liver disease in the mothers and in adult female offspring, but not in male offspring, with each group showing different underlying molecular mechanisms. The study suggests that prenatal exposure to airborne nanoplastics may have sex-specific effects on metabolic health that persist into adulthood.
Maternal nanoplastic ingestion induces an increase in offspring body weight through altered lipid species and microbiota
Researchers found that when mother mice ingested nanoplastics derived from polystyrene and polypropylene during pregnancy and nursing, their offspring showed increased body weight gain. The weight changes were associated with alterations in fat metabolism and shifts in gut microbiome composition in the pups. The study suggests that maternal exposure to nanoplastic pollution may act as an environmental factor contributing to weight gain in offspring.
Polystyrene nanoplastics-induced altered glycolipid metabolism in the liver: A comparative study between pregnant and non-pregnant mice
Researchers compared glycolipid metabolism effects of polystyrene nanoplastics in pregnant versus non-pregnant mice, finding that pregnancy amplified hepatic lipid disruption, with both low and high doses impairing fat metabolism and altering glucose regulation more severely during gestation.
Maternal exposure to polystyrene nanoparticles retarded fetal growth and triggered metabolic disorders of placenta and fetus in mice
Researchers exposed pregnant mice to polystyrene nanoplastics through drinking water and found that higher concentrations led to significantly reduced fetal weight. The nanoplastics caused abnormal cell structures in the placenta and disrupted metabolic processes in both placental tissue and fetal livers. The study suggests that maternal nanoplastic exposure during pregnancy can cross the placental barrier and interfere with normal fetal growth and metabolism.
Maternal Polystyrene Microplastic Exposure during Gestation and Lactation Altered Metabolic Homeostasis in the Dams and Their F1 and F2 Offspring
Researchers exposed pregnant mice to polystyrene microplastics during pregnancy and nursing and found significant metabolic disruptions in both the mothers and their offspring across two generations. The microplastics altered lipid metabolism, gut microbiota composition, and key metabolic signaling pathways. The study suggests that microplastic exposure during critical developmental windows may have lasting health consequences that pass to future generations.
Maternal exposure to different sizes of polystyrene microplastics during gestation causes metabolic disorders in their offspring
Researchers exposed pregnant mice to polystyrene microplastics of two different sizes during gestation and examined metabolic effects in their offspring. They found that maternal microplastic exposure altered cholesterol, triglyceride levels, and amino acid metabolism in the offspring, with larger 5-micrometer particles causing more pronounced effects. The study suggests that prenatal microplastic exposure may increase the risk of metabolic disorders in the next generation.
Maternal exposure to polystyrene nanoplastics impacts developmental milestones and brain structure in mouse offspring
Researchers exposed pregnant mice to polystyrene nanoplastics and studied the effects on their offspring's brain development. The study found that maternal nanoplastic exposure affected developmental milestones and brain structure in the young mice. The findings suggest that nanoplastic exposure during pregnancy may pose risks to fetal brain development, though more research is needed to understand the implications for humans.
Nanopolystyrene translocation and fetal deposition after acute lung exposure during late-stage pregnancy
Researchers exposed pregnant mice to nanoscale polystyrene particles through inhalation and tracked where the particles traveled. They found that the nanoplastics crossed from the lungs into the bloodstream and accumulated in both placental and fetal tissues, confirming that inhaled plastic nanoparticles can reach developing offspring during pregnancy.
Maternal exposure to polystyrene nanoplastics causes brain abnormalities in progeny
Researchers found that maternal exposure to polystyrene nanoplastics caused brain abnormalities in offspring, demonstrating that nanoplastics can cross maternal barriers and affect neurological development in progeny with implications for developmental toxicology.
Nanopolystyrene Translocation and Fetal Deposition After Acute Lung Exposure During Late-Stage Pregnancy
Nanopolystyrene particles inhaled by pregnant mice during late pregnancy crossed into the bloodstream and deposited in fetal tissues. This finding raises concern that airborne nanoplastics could pose a risk to fetal development, especially given growing human exposure to plastic particles in indoor and outdoor air.
Exposure to Nanoplastics During Pregnancy Induces Brown Adipose Tissue Whitening in Male Offspring
Researchers found that exposing pregnant mice to polystyrene nanoplastics caused changes in the brown fat tissue of their male offspring, shifting it toward white fat characteristics associated with obesity. This transformation was driven by disruptions in fat production and a cellular recycling process called lipophagy. The study suggests that nanoplastic exposure during pregnancy could increase obesity risk in offspring by altering how their bodies regulate fat storage and energy burning.
Nanopolystyrene translocation and fetal deposition after acute lung exposure during late-stage pregnancy
Researchers found that nanoscale polystyrene particles inhaled by pregnant mice were able to cross into the placenta and deposit in fetal tissues. The findings raise concerns about potential developmental risks from airborne nanoplastic exposure during pregnancy.
Maternal exposure to polystyrene nanoplastics leads to ovotoxicity in female mouse offspring
Researchers exposed pregnant mice to polystyrene nanoplastics throughout mating, pregnancy, and nursing, then examined the ovaries of their female offspring. They found that maternal nanoplastic exposure significantly reduced ovarian weight and follicle numbers in the offspring and lowered the expression of key antioxidant genes. The study suggests that nanoplastic exposure during pregnancy may pose risks to the reproductive development of female offspring.
Maternal exposure to polystyrene nanoplastics during gestation and lactation induces hepatic and testicular toxicity in male mouse offspring
Researchers exposed pregnant and nursing mice to polystyrene nanoplastics and studied the effects on their male offspring. The offspring showed reduced body weight, liver damage with inflammation and disrupted sugar metabolism, and testicular harm including decreased sperm counts. The findings suggest that nanoplastic exposure during pregnancy and breastfeeding can cause significant organ damage in the next generation.
Nanopolystyrene translocation and fetal deposition after acute lung exposure during late-stage pregnancy
This animal study found that nanopolystyrene particles inhaled by pregnant mice during late pregnancy were transferred across the placenta and deposited in fetal tissues. The findings provide experimental evidence that airborne nanoplastics can reach unborn fetuses, raising serious concerns about developmental exposure from breathing indoor or outdoor air containing plastic particles.
Dual impact of microplastic exposure in a mouse model: Impaired uterine receptivity and altered maternal-offspring metabolism
Researchers exposed female mice to polystyrene microplastics and found that the particles impaired uterine receptivity, which is critical for embryo implantation, and altered metabolic profiles in both the mothers and their offspring. The microplastics disrupted gene expression related to uterine function and caused metabolic changes across multiple organs. The findings suggest that microplastic exposure could have reproductive and metabolic consequences that extend to the next generation.
Teratological, neurochemical and histomorphic changes in the limbic areas of F1 mice progeny due to co-parental polystyrene nanoplastic exposure
Researchers exposed parent mice to polystyrene nanoplastics before and during pregnancy and found that offspring exhibited skeletal and visceral malformations, impaired neonatal reflexes, learning deficits, and structural brain changes — including reduced hippocampal neurons — demonstrating transgenerational neurodevelopmental harm from nanoplastic exposure.
Maternal Exposure to Polystyrene Micro- and Nanoplastics Causes Fetal Growth Restriction in Mice
Researchers exposed pregnant mice to polystyrene micro and nanoplastics and found that exposure caused fetal growth restriction and placental abnormalities. The study observed that plastic particles accumulated in placental tissue and disrupted normal placental function. These findings raise concern that maternal exposure to plastic particles during pregnancy may interfere with fetal development.
[The effect and mechanism of exposure to polystyrene nanoplastics on lipid metabolism in mice liver].
Researchers exposed mice to 20 nm polystyrene nanoplastics and investigated the effects on hepatic lipid metabolism using multi-omics approaches. Nanoplastic exposure disrupted lipid metabolic pathways in the liver, causing significant changes in lipid accumulation and related gene expression, suggesting a mechanism by which nanoplastic ingestion may contribute to metabolic disorders.

Researchers used gene expression and metabolic profiling to understand how polystyrene nanoplastics harm mice at the molecular level, finding disrupted energy metabolism, fat processing, and amino acid pathways in the liver. These molecular changes suggest that nanoplastic exposure could contribute to metabolic disorders, with effects becoming more severe at higher doses.
Maternal exposure to polystyrene nanoplastics causes brain abnormalities in progeny
When pregnant mice were exposed to polystyrene nanoplastics, their offspring showed abnormal brain development including changes in neural stem cell function, altered brain structure, and cognitive problems. The effects were gender-specific, with some deficits appearing more strongly in one sex. This study raises concerns that nanoplastic exposure during pregnancy could increase the risk of neurodevelopmental problems in children.
