Bottled water contains up to 100 times more microplastics than previously estimated, with an average of 240,000 particles per liter detected through new analysis methods.

This advice is based on a study published in PNAS (2024) using stimulated Raman scattering microscopy, a technology capable of detecting much smaller particles (nanoplastics) than previous methods. Science confirms that these polymers are ubiquitous in bottled water, primarily originating from the plastic of the container and the cap. What holds up: the technical measurement is robust and represents a major advancement in detection precision. What is nuanced: although the presence of these particles is verified, the long-term biological consequences for human health remain an active area of research and have not yet been settled by clinical consensus. It is not an exaggeration to highlight this presence, but it is important to distinguish physical measurement from proven toxicity, which is still the subject of observational and in vitro studies.
