Scientists have discovered toxic ‘Forever Chemicals’ present in samples of drinking water from around the world, a new study reveals. Researchers found 10 ‘target’ PFAS (perfluoroalkyl substances) – chemicals which do not break down in nature – in tap and bottled water available for consumption in major cities in the UK and China. Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) were detected in over 99% of samples of bottled water sourced from 15 countries around the world.
They observed significant differences in PFAS concentrations between tap water samples from Birmingham, UK, and Shenzhen, China, with Chinese tap water found to have higher concentrations of PFAS compared to UK tap water. “While current PFAS levels in most water samples are not a major health concern, ongoing monitoring and regulation are crucial to protect public health. We provide valuable data on the presence of PFAS in drinking water alongside practical solutions to mitigate consumer exposure via drinking water. This is a significant step towards ensuring safer drinking water for communities worldwide.”
Bottled water from various countries showed varying levels of PFAS, with natural mineral water containing higher concentrations than purified water, but the concentrations were generally below health advisory levels set by regulatory agencies.
