PFAS Research at NERI

Per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals,” are harmful pollutants that remain in the environment and have the tendency to build up in living organisms. Present in water, soil, air, and even consumer goods, PFAS pose serious risks to both human health and ecosystems. However, their detection, monitoring, and treatment continue to be a major scientific and regulatory challenge.

At the NUS Environmental Research Institute (NERI), our researchers are addressing PFAS through various approaches. Teams are investigating airborne PFAS in warm and humid urban settings where detection techniques are still lacking, as well as monitoring their occurrence, transformation, and bioaccumulation in aquatic ecosystems. Additional studies focus on how flame retardants utilised in forest fire management introduce PFAS into vulnerable peatland ecosystems and local food chains, influencing both environmental and community health.

In terms of treatment, NERI researchers are developing novel and affordable solutions. These range from adsorption, membrane separation, and advanced oxidation processes to electrochemical methods capable of breaking down PFAS while reducing harmful byproducts. Backed by state-of-the-art facilities and cross-disciplinary expertise, our work focuses on enhancing the understanding PFAS-related risks and deliver practical technologies for improving water safety and fostering healthier ecosystems.

As we further expand our PFAS research, NERI invites partnerships with industry leaders and government agencies to co-develop sustainable solutions for a PFAS-safe environment.
