Microplastics, pregnancy and the placenta: what we know and what we don’t
AI summary Read the abstract
Researchers reviewed current evidence on microplastic accumulation in the placenta during pregnancy, examining what is known about how these particles cross or are blocked by placental tissue and what gaps remain regarding potential developmental consequences for the fetus.
During pregnancy, the placenta is the lifeline between mother and baby. It supplies the foetus with oxygen and nutrients, removes waste products and acts as a partial shield against harmful substances…

The Dangers of Exposure to Microplastics during Gestation
AI summary Read the abstract
Researchers reviewed the dangers of microplastic and micro-nano plastic particle (MNP) exposure during pregnancy, finding evidence that MNPs cross the placental barrier, accumulate in fetal tissues, and can cause oxidative stress, epigenetic alterations, and disruption of fetal organ development.
Health Risks of Prenatal and Early-Life Microplastics Exposure: A Comprehensive Review
AI summary Read the abstract
Researchers reviewed current evidence that microplastics cross the placental barrier and affect fetal development through oxidative stress, inflammation, endocrine disruption, and epigenetic alterations, summarizing experimental findings linking prenatal and early-life exposure to neurodevelopmental, reproductive, and immune abnormalities — often in a sex-dependent manner — while identifying major gaps in human dose-response data.
Embryonic Exposure Towards Microplastic: Its Causes and Effects
AI summary Read the abstract
Researchers reviewed how embryonic and early-life exposure to microplastics and nanoplastics disrupts reproductive development and aquatic organism physiology, highlighting particular concern for developmental toxicity given the vulnerability of embryos to oxidative stress and endocrine disruption caused by plastic particles.
Microplastics in Human Health
AI summary Read the abstract
Researchers reviewed the detection of microplastics across freshwater, marine, and terrestrial environments and synthesized emerging evidence on their health effects in humans. The paper examines how particle characteristics — origin, shape, and polymer type — influence toxicological outcomes and bioavailability.
Impact of Microplastics in Human Health
AI summary Read the abstract
Researchers examined how the global proliferation of plastic products has led to pervasive microplastic pollution through slow degradation of discarded materials, with direct consequences for human health. The paper traces the pathway from plastic convenience to microscale contamination and the biological impacts on the human body.
