Placental Exposure to Nanoplastics Threatening the Maternal and Fetal Health
AI summary Read the abstract
This review examines how nanoplastics reaching the placenta threaten maternal and fetal health, summarizing evidence from animal and in vitro studies showing that placental nanoplastic accumulation disrupts nutrient transport, immune function, and fetal development.

Biological interactions between nanomaterials and placental development and function following oral exposure
AI summary Read the abstract
Researchers reviewed animal studies on orally ingested nanomaterials (including nanoplastics) and found that while the placenta is generally an effective barrier preventing fetal transfer, nanomaterials accumulating in placental tissue can impair placental development and function, with potential downstream effects on fetal health.
Assessing microplastics as a novel threat to maternal-fetal health: Placental barrier penetration and fetal developmental consequences
AI summary Read the abstract
This review addressed how microplastics cross the placental barrier and affect fetal development, covering cellular responses in placental tissue, animal model findings, and limited human study data. The authors concluded that transplacental microplastic transfer is a plausible mechanism for intergenerational health effects.
A Systematic Review of the Placental Translocation of Micro- and Nanoplastics
AI summary Read the abstract
Nine out of eleven studies confirmed that micro- and nanoplastics can cross the placental barrier, with translocation depending on particle size, charge, chemical modification, and protein corona formation. Animal and in vitro studies showed emerging evidence of placental and fetal toxicity from plastic particle exposure.
Breach of Security? Placental Uptake of Micro- and Nanoplastic Particles
AI summary Read the abstract
This review examines emerging evidence for placental uptake of micro- and nanoplastic particles, exploring whether the placenta's barrier function can be breached by these contaminants during pregnancy. The review raises concerns about potential fetal exposure to plastic particles and the implications for developmental health.
Micro- and nanoplastic inhalation during pregnancy: Impacts on uteroplacental function and offspring health
AI summary Read the abstract
This review examined evidence that inhaled micro- and nanoplastics during pregnancy accumulate in placental and fetal tissues, impair uteroplacental blood flow and immune function, and are associated with adverse developmental outcomes in offspring, identifying inhalation as a critical but understudied exposure route.
