Wellington plays a key role in providing reference standards and developing advanced analytical methods for the detection of fluorotelomer sulfonates (FTS) and their derivatives. methods for the detection of Fluorotelomer Sulfonates (FTS) and their derivatives, enabling accurate and reliable environmental monitoring.
Why use fluorotelomer sulfonates (FTS)?
In recent years, strict restrictions on perfluorooctane sulfonic acid(PFOS), a highly persistent and bioaccumulative fluorinated compound, have encouraged the adoption of fluorotelomer sulfonates (FTS) as substitutes in many industrial and commercial applications, including fire-fighting foams, surface treatment agents, and fog suppressants. This move to FTS is driven by a reduction in the use of the more problematic PFASs (perfluoroalkylated and polyfluoroalkylated substances), but raises concerns about the potentially similar environmental effects of FTSs.
Biotransformation and formation of secondary PFAS
Once FTS are released into the environment, they do not remain in their initial form. In landfill leachates , they often undergo chemical transformations , called biotransformations, under the action of micro-organisms or environmental processes. These reactions lead to the formation of secondary PFAS compounds, such as perfluoroalkylcarboxylic acids (PFCA), which can be even more toxic and persistent. This transformation phenomenon makes the detection of FTSs and their by-products complex, requiring specialised analytical tools.
The need for enhanced environmental monitoring
Due to their persistence and associated risks, FTS are now included in analytical reference protocols for monitoring PFAS in the environment. These protocols incorporate advanced detection and quantification methods, often coupled with labelled reference standards, which enable accurate analysis of these contaminants at very low concentrations. Labelled standards, in particular, play a crucial role in improving the reliability of measurements in various environmental matrices such as wastewater, soil and biological tissue.
