ClearMicroplastics in the Perinatal Period: Emerging Evidence on Maternal Exposure, Placental Transfer, and Fetal Health Outcomes
This review summarizes emerging evidence that microplastics can cross the placenta and reach developing babies, having been detected in maternal blood, placental tissue, amniotic fluid, cord blood, and breast milk. The tiny plastic particles may damage the placenta, disrupt hormones, alter immune responses, and potentially affect fetal growth and brain development. While more research is needed, the findings raise serious concerns about microplastic exposure during pregnancy and its implications for infant health.

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.
Impact of Microplastics on Pregnancy and Fetal Development: A Systematic Review
A systematic review of 12 studies confirmed the presence of microplastics ranging from 2.1 to 100 micrometers in human placentas and fetal tissue. Microplastic levels correlated with reduced birthweight, affected gestational age, diminished microbiome diversity, and impaired fetal growth and development, with lifestyle choices influencing placental microplastic burden.
Assessing microplastics as a novel threat to maternal-fetal health: Placental barrier penetration and fetal developmental consequences
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.
Breach of Security? Placental Uptake of Micro- and Nanoplastic Particles
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 Nanoplastics and Fetal Health: Challenges in Assessment and Evidence from Epidemiological Studies
This review examines the emerging evidence that micro- and nanoplastics can reach the developing fetus during pregnancy, with animal studies showing potential effects on neurological development and placental blood flow. The study also highlights major challenges in accurately detecting and measuring these tiny particles in biological tissues from mothers and babies. The authors call for standardized methods and more human studies to better understand the risks of prenatal microplastic exposure.
Microplastics: A threat to Fetoplacental unit and Reproductive systems
This review examines how micro- and nanoplastics may harm the placenta and reproductive system, particularly during pregnancy. The authors highlight that these tiny plastic particles have been found in placental tissue and may interfere with fetal development, though they note that much more research is needed to understand the full risks to mothers and babies.
Unveiling the presence of micro and nanoplastics in human biological matrices: A systematic review covering the latest five years from 2020 to 2025
This systematic review covering 2020-2025 confirmed the presence of micro- and nanoplastics in human blood, placenta, lungs, liver, kidneys, and other biological matrices. The findings demonstrate that plastic particles are accumulating in human tissues through ingestion, inhalation, and dermal contact, raising urgent questions about long-term health consequences.
Microplastic Exposure and Human Health: Advancing Risk Assessment and Future Research Directions
This review synthesizes recent evidence that microplastics are present in human blood, respiratory tissue, placenta, and gut, examines proposed toxicological mechanisms, and identifies priorities for improving risk assessment frameworks and exposure measurement methods.
Study of Microplastics in Human Blood
This study reviewed findings on microplastic contamination in human blood, noting that particles have been detected in the majority of samples tested, while the health consequences remain unclear and warrant urgent further investigation.
Microplastics exposure: implications for human fertility, pregnancy and child health
This review examines growing evidence that microplastics accumulate in the human placenta and may affect pregnancy outcomes and child development. Given that exposure during pregnancy can program lifelong health in offspring, the presence of these tiny plastic particles in reproductive tissues raises important concerns about fertility, pregnancy complications, and children's health.
The Invisible Intruder: a Review of Microplastics Accumulation in Human Tissues and Implications for Public Health, with Emphasis on Reproductive Health
This review synthesizes biomonitoring studies on microplastic and nanoplastic accumulation in human tissues, with particular emphasis on reproductive health effects. Researchers found these particles have been detected in blood, lungs, placentas, breast milk, testes, and brain tissue, raising questions about potential long-term implications for human health and reproduction.
Micro(Nano)Plastics as Carriers of Toxic Agents and Their Impact on Human Health
This review compiles evidence on how micro- and nanoplastics act as carriers of potentially toxic agents and enter the human body through inhalation, ingestion, and dermal absorption. Evidence indicates that continuous exposure to these particles can lead to bioaccumulation and negative health alterations, with recent research detecting microplastics even in human placental tissue.
Microplastics in Human Tissues: Sources, Distribution, Toxicological Effects, and Health Implications
Researchers reviewed the growing body of evidence that microplastics accumulate in human tissues — including lung, blood, placenta, breast milk, and heart tissue — where they can trigger inflammation, oxidative stress, and cell death. The review highlights urgent knowledge gaps around how plastic particles move through the body and what their long-term health effects may be.
Microplastics in maternal blood, fetal appendages, and umbilical vein blood
Researchers detected 16 different types of microplastics in maternal blood, umbilical cord blood, and fetal tissues (placenta, amniotic fluid, fetal membrane, and umbilical cord) from 12 pregnant women who delivered by cesarean section. The most common plastics found were polyamide and polyurethane, and microplastic levels in amniotic fluid increased with maternal age and pre-pregnancy body weight, confirming that these particles can pass from mother to fetus.
Impact of Microplastic Exposure on Human Health: A Systematic Review of Mechanisms, Biomarkers, and Clinical Outcomes
This systematic review found that microplastics have been detected in human blood, placental tissue, and gastrointestinal samples, with proposed health mechanisms including oxidative stress, chronic inflammation, endocrine disruption, and gut microbiome alterations. While direct clinical evidence remains limited, the accumulating laboratory and observational data point to microplastics as a plausible contributor to multiple disease pathways.
A Systematic Review of the Placental Translocation of Micro- and Nanoplastics
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.
Systemic Accumulation and Distribution of Micro- and Nanoplastics in Human Tissues and Their Impact on Health: A Systematic Review
This systematic review synthesizes human evidence on the presence of micro- and nanoplastics in body tissues and fluids, including blood, lungs, placenta, breast milk, and liver. The research confirms that plastic particles can cross biological barriers and accumulate in multiple organ systems. While the long-term health effects are still being studied, the widespread presence of plastics inside the human body raises significant health concerns.
