PFAS can be removed from contaminated water by Australian native rushes. |
They’re the non-stick on Teflon cookware, the stain resistance in Scotchgard, and the suppression factor in firefighting foam, but while the staying power of PFAS chemicals was once revered, it’s now infamous as PFAS substances continue to infiltrate the environment and affect human health.
Now, new research from the University of South Australia is helping to remediate the ‘indestructible’ PFASs as scientists show that Australian native plants can significantly remediate PFAS pollutants through floating wetlands to create healthier environments for all.
Conducted in partnership with CSIRO and the University of Western Australia, the research found that PFAS chemicals (per- and poly-fluoroalkyl substances) can be removed from contaminated water via Australian native rushes - Phragmites australis, Baumea articulata, and Juncus kraussii.
Phragmites australis, otherwise known as the common reed, removed legacy PFAS contaminants by 42-53 per cent from contaminated surface water (level: 10 µg/L).
