A new analysis of some of the world’s most popular bottled water brands says more than 90% contain tiny pieces of plastic.
Analysis of 259 bottles from 19 locations in nine countries across 11 different brands found an average of 325 plastic particles for every litre of water being sold.
Concentrations were as high as 10,000 plastic pieces for every litre of water.
Of the 259 bottles tested only 17 were free of plastics according to the study which was published as the World Health Organisation announced it would launch a review into the potential risks of plastic in drinking water.
Scientists based at the State University of New York in Fredonia were commissioned by journalism project Orb Media to analyse the bottled water.
The scientists wrote they had ‘found roughly twice as many plastic particles within bottled water’ compared with their previous study of tap water.
