Evidence Status and Assessment Challenges of Microplastic Exposure on Neonatal Health Outcomes
AI summary Read the abstract
This review summarizes existing research on microplastics found in the placenta, amniotic fluid, umbilical cord blood, breast milk and meconium. Observational studies link microplastic pollution to lower birth weight and shorter pregnancies, while experimental studies report oxidative stress and inflammation in offspring, though data remain limited and inconsistent.
Microplastics have become ubiquitous pollutants in our environment. Recent evidence suggests that these particles can cross the placenta and hence they pose a potential threat to fetal development and neonatal health. In this paper the literature on the influence of microplastics on perinatal biological media and the health consequences of their presence is systematically analyzed. The studies reveal the presence of microplastics in the placenta, amniotic fluid, umbilical cord blood, breast milk, and in meconium. The polymer types mainly include polyethylene, polypropylene and polystyrene. The observational studies indicate that microplastic pollution may negatively affect birth outcomes, including low birth weight and shorter gestation periods. The experimental studies show that microplastics negatively impact the health of offspring, causing oxidative stress, inflammation, and various defects. However, the existing population epidemiological data on the topic is still limited and inconsistent due to small sample sizes, methodological inconsistencies, complexity of confounders, and imprecision in toxicological conclusions. In this paper, four problems constraining the assessment of perinatal health risks of microplastics have been identified and specific solutions for the scientific and healthcare practices have been proposed.

Micro- and Nanoplastics and Fetal Health: Challenges in Assessment and Evidence from Epidemiological Studies
AI summary Read the abstract
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.
Impact of Environmental Microplastics on Pregnancy and Neonatal Outcomes: A Scoping Review
AI summary Read the abstract
Tiny plastic particles called microplastics have been found in placentas, amniotic fluid, and other tissues involved in pregnancy, and this review of 53 studies found early evidence linking them to changes in fetal growth, birth weight, and gene activity in animal and lab studies. While these findings are concerning, most of the research so far is in animals or cells rather than humans, so scientists still need to confirm whether microplastic exposure actually causes problems for pregnant people and their babies.
Health Implications of Microplastic Exposure in Pregnancy and Early Childhood: A Systematic Review
AI summary Read the abstract
This systematic review summarizes existing research on how microplastic exposure during pregnancy and early childhood may affect health. The evidence shows that microplastics can reach the placenta and may cause oxidative stress and inflammation, raising concerns about potential effects on fetal development and infant health during these vulnerable life stages.

AI summary Read the abstract
This scoping review compiled existing literature on micro- and nanoplastic exposure in relation to women's health and reproductive outcomes. The study identified inverse associations between microplastic exposure and adverse neonatal outcomes such as low birth weight, and highlighted physiological routes of absorption and vulnerable organs, while noting significant gaps in current knowledge that need to be addressed.
Early life in the Plasticene: short- and long-term effects of perinatal exposure to microplastics and plastic-associated chemicals – PART I
AI summary Read the abstract
This review summarizes existing research on how babies may be exposed to microplastics and plastic chemicals before birth. Studies found microplastics in the placenta, amniotic fluid and cord blood, with possible links to altered fetal growth and hormone levels, though evidence remains preliminary and limited by inconsistent study methods.
