What plastic types have been found in the placenta?
A 2026 study found PVC, polypropylene, PBS, and PET microplastics in placental tissue.
What is actually in it
The placenta helps move oxygen and nutrients from parent to baby during pregnancy. Researchers are now finding microplastics in placental tissue.
Microplastics are tiny plastic pieces. The 2026 study looked for specific polymer types, including PVC, polypropylene, PBS, and PET.
What the research says
A 2026 study in Ecotoxicol Environ Saf studied 1,750 mother-infant pairs in China. Median placental levels were 7.0 particles per 10 grams for PVC, 5.0 for polypropylene, 4.0 for PBS, and 3.0 for PET.
Higher total placental microplastic levels were linked with lower birth weight, birth length, and head circumference. This was a cross-sectional study, so it shows an association, not proof of cause.
You cannot control every exposure. You can reduce obvious plastic contact in the home. For baby gear, choose wood, cotton, glass, or stainless steel when those swaps fit your routine.
