Toxic forever chemicals found in Australian rainwater

Researchers from RMIT University and EPA Victoria have detected eight PFAS (per- and polyfluoroalkyl substances) compounds in Melbourne's rainwater samples collected between 2024 and 2025. However, the concentrations found were well below the drinking water guidelines set by the National Health and Medical Research Council. Professor Oliver Jones, an analytical chemist, emphasized that there's no need to worry about rainwater containing PFAS chemicals as they would not cause any harm if consumed.

The study also sheds light on how PFAS chemicals can reach waterways from seemingly unexpected sources, suggesting that atmospheric transport could be a significant pathway. PFAS are a vast group of human-made chemicals used in various products, and their persistence in the environment has raised concerns. The researchers hope their findings will help policymakers make informed decisions regarding PFAS regulations in the future.
