Microplastics in humans: first look at how they travel inside us
NCT ID NCT07075991
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study gave 6 healthy adults a single tiny dose of labeled microplastics to track how much gets absorbed into the blood and how it leaves the body through urine and stool. Participants provided samples over 5 days. The goal is to understand basic movement of microplastics in humans, not to test a treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- 1 μm [14C]-labelled polystyrene microplastic particles
- What this could lead to
- If successful, this could reveal how much microplastic enters the bloodstream and how the body clears it, informing future health risk assessments.
- What could go wrong
- This is a very small, early-stage study with only 6 participants and no comparison group. Results may not apply to larger populations or different microplastic types.
