A Columbia team counted about 240,000 plastic particles in a litre of bottled water and put their mass at roughly 10 nanograms: four and a half years into treaty talks there is no agreed text, and the only microplastics banned EU-wide are microbeads and glitter

In January 2024 a team at Columbia and Rutgers published a new way of counting plastic in water, and used it on three brands of bottled water bought from a single large retailer. They found roughly 240,000 particles per litre, about 90 per cent of them nanoplastics small enough to have been invisible to every previous method.
The same paper contains the number that almost never travels with it. All 240,000 particles together weigh about 10 nanograms.
Those two figures are both correct, and holdi
