Have microplastics been found in placentas and are they a risk during pregnancy?

Microplastic particles have been detected in human placental tissue in multiple studies. A 2020 Italian study first reported finding microplastics in placentas, and subsequent research has confirmed these findings across different populations. The particles found included fragments of polypropylene, polyester, and other synthetic polymers consistent with textile and packaging origins.

The placenta serves as the critical interface between mother and fetus, regulating nutrient transfer and providing a barrier against harmful substances. The presence of microplastics in this tissue raises concerns about potential effects on fetal development, though long-term research is still in early stages. Preliminary findings suggest microplastics may trigger inflammatory responses in placental tissue.

Pregnant women may wish to reduce microplastic exposure as a precautionary measure. This includes choosing natural-fiber clothing (especially undergarments and loungewear worn against the body for extended periods), using natural-fiber bedding, filtering drinking water, and reducing consumption of food stored in plastic containers. ONDU's mission of promoting natural-fiber clothing aligns with the precautionary approach recommended for vulnerable populations.
