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.
The paper is here.
Looks rather like contamination from the packaging process – it’s higher than in tap water for example.
My own reaction was we’ve an average of 23 pieces per litre of water (median, I think) and pieces are divided into more than 100 nm and less than (so, perhaps 50 nm on average for the smaller group). nm is a millionth of a metre.
Me, I’m going to go with this being equal to nothing in the vernacular. But I’ll admit that I get lost in 10-6, volume and length measurements and so on. Anyone like to tell us all what this actually is as contamination in ppm, or ppb?
It would be fun if this plastics concentration was less than, say, the allowable levels of As in drinking water…..
