Nanoplastics Shut Down Energy Production in Placentas

Polystyrene nanoparticles shut down the energy-producing machinery in placental cells. Without that energy, the placenta can't develop properly.

How Nanoplastics Starve the Placenta

A 2026 study in Toxics found that polystyrene nanoparticles disrupt oxidative phosphorylation in placental cells. That's the process mitochondria use to produce energy. When it fails, cells can't function. The result: impaired placental development in mice.

A healthy placenta requires massive amounts of energy to grow blood vessels, transfer nutrients, and support the fetus. Nanoplastics are hitting the power supply. Without adequate energy production, the placenta develops poorly, which can lead to growth restriction, preeclampsia, and other complications.

The Scale of Exposure

Pregnant women encounter nanoplastics every day through food packaging, water bottles, household dust, and synthetic clothing. These particles are small enough to enter the bloodstream and reach the placenta. Once there, they interfere with the most basic cellular function: making energy.

What You Can Do

Cut plastic from your food routine. Use glass containers and water bottles. Avoid heavily packaged processed food. Dust your home with damp cloths to capture particles. Check out non-toxic baby products for plastic-free options during pregnancy.
