Are microplastics found in the placenta and umbilical cord blood?

Yes, researchers have detected microplastic particles in human placentas, umbilical cord blood, and even meconium, the first stool passed by newborns. This means that microplastic exposure begins before birth, with particles crossing the placental barrier to reach the developing fetus. Studies have identified a range of polymer types in placental tissue, including polyester, polyethylene, and polypropylene, many of which originate from textiles.

The presence of microplastics in the placenta is associated with metabolic disruption that can lead to intrauterine growth restriction (IUGR) and lower birth weights. The placenta acts as the interface between mother and baby, managing nutrient transfer, waste removal, and hormone production. When microplastics interfere with placental function, they can alter how nutrients reach the fetus and disrupt the hormonal signals that regulate healthy fetal development.

Expectant mothers can reduce their microplastic exposure by prioritizing natural-fiber clothing, particularly garments worn for extended periods like sleepwear, loungewear, and underwear. Bedding is equally important since pregnant women spend significant time in bed.
