Imagine a chemical so persistent that it resists breaking down in the environment, earning it the nickname “forever chemical.” Per- and polyfluoroalkyl substances (PFAS) are just that—synthetic compounds found in everyday items like non-stick cookware, waterproof clothing, and firefighting foams. While their durability made them industrial favourites, this same resilience has led to widespread environmental contamination. In South Africa, the presence of PFAS in water sources is becoming an increasing concern, prompting questions about their impact on health and the environment.
Unpacking the PFAS puzzle
PFAS have been linked to various health issues, including hormonal disruptions, immune system effects, and certain cancers. Their ability to accumulate in the human body and the environment makes them particularly worrisome. In South Africa, studies have detected PFAS in water sources, raising alarms about potential exposure. However, detecting and analysing these compounds is no simple task. Their chemical stability and low concentrations in environmental samples pose significant challenges for laboratories, necessitating advanced analytical techniques and instruments.
Traditional analytical methods often fall short when it comes to detecting the vast array of PFAS compounds, especially at trace levels. Non-targeted analysis (NTA) and suspect screening have emerged as crucial approaches, allowing scientists to identify both known and unknown PFAS compounds in various matrices. However, these methods require high-resolution mass spectrometry and sophisticated data analysis capabilities. In South Africa, the adoption of such advanced techniques is still in its nascent stages, highlighting the need for enhanced laboratory infrastructure and expertise to effectively monitor and manage PFAS contamination.
