Can houseplants protect lab workers from toxic fumes?
NCT ID NCT07264504
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether placing 15 houseplants in two hospital lab rooms can reduce formaldehyde levels in the air and in workers' urine. Formaldehyde is a toxic chemical used to preserve tissue samples. Thirty adult lab staff will have their exposure measured before and two months after plants are installed. The goal is to see if plants can help make the workplace safer.

- houseplants
- What this could lead to
- If it works, this could point toward a simple, low-cost way to reduce toxic chemical exposure in workplaces.
- What could go wrong
- This is a very small, early study with only 30 participants. Plants may not lower formaldehyde enough to make a real difference, and results may not apply to other settings.
