Leeder Analytical is proud to have collaborated with Curtin University and other partners on a groundbreaking study investigating the potential of the aquatic plant Azolla filiculoides for the remediation of per- and polyfluoroalkyl substances (PFAS). The findings of this innovative research have been published in the prestigious Journal of Environmental Toxicology and Chemistry.
Addressing PFAS Contamination
PFAS, commonly referred to as “forever chemicals,” are highly persistent environmental pollutants with significant health risks, including cancer and immune system disruptions. These chemicals often contaminate aquatic systems, particularly in locations such as firefighting training grounds where aqueous film-forming foams are used.
This study explored the potential of phytoremediation, the use of plants to remove or reduce contaminants in water, to address this critical environmental issue.
Key Study Highlights
- Aquatic Plant as a Remediation Tool:
The water fern Azolla filiculoides was tested for its ability to uptake and remove seven common PFAS chemicals from water. - Environmentally Realistic Testing:
The study used PFAS concentrations typically found in contaminated environments, ensuring the findings are relevant to real-world conditions. - Results:
- Rapid PFAS uptake by the plant occurred within the first six days of exposure.
- While all seven PFAS were accumulated in the plant tissues, the bioconcentration factors (BCFs) were low, with a maximum of 1.30 for one compound.
- The study concluded that Azolla filiculoides alone would not be sufficient for large-scale PFAS remediation but could play a role in multi-stage clean-up strategies.
Leeder Analytical’s Contribution
With over 20 years of experience in advanced chemical analysis, Leeder Analytical provided state-of-the-art analytical capabilities to this study, including the use of ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS).
Dr. John Leeder, Managing Director of Leeder Analytical, noted, “This research is a step forward in understanding how phytoremediation can be part of the solution to PFAS contamination. We’re proud to collaborate with leading institutions to address this pressing environmental challenge.”
The Path Forward
This study highlights the need for further large-scale research to determine how aquatic plants like Azolla filiculoides could be integrated into multi-stage water treatment systems. The findings underscore the importance of collaborative research efforts in advancing innovative solutions for environmental remediation.
