Scientists say that most microplastics found in drinking water are very fine and thus more likely to pass from the human intestine into the blood and organs.
ADVERTISEMENTMost microplastics found in bottled and tap water samples were smaller than 20 microns (μm), according to researchers who are urging the European Union to update its recommended detection limit to include these fine plastic particles.
Scientists tested 10 different bottled water brands and one tap water source in Toulouse, France with a new method to detect fine microplastics smaller than 20 μm, which to date have been omitted from many studies due to detection limitations, they say.
A recent March 2024 methodology decision from the European Union on measuring microplastics in drinking water limits it to larger particles “with a…
