Research on plastic in water bottles
Peer-reviewed journals, government agencies, and standards bodies.
“The researchers found that, on average, a liter of bottled water included about 240,000 tiny pieces of plastic.”
“They found that on average, a liter contained some 240,000 detectable plastic fragments—10 to 100 times greater than previous estimates, which were based mainly on larger sizes.”
