"Somewhat concerningly, the seven plastics tested accounted for only about 10% of all the nanoplastics the researchers found in the bottled water. They had no idea what the others were and whether they are, in fact, nanoplastics."
Eh? I'm far too much of an ignoramus to make sense of the original paper, but this is a pretty weird claim.
I do know that 10^5 nanoparticles per liter is an incredibly tiny amount of mass. Assuming an average particle size of 200nm, by my reckoning that would make the water 0.00000000004% plastic, which doesn't seem all that worrying.
- throwaway290 3y agoIf it was like dust or sand it would be 1000x mass and size but 0 issue. Small size is the problem here. Micro means it crosses directly into tissue and nano means it gets into individual cells and screws up their business. Want to put a number on how much plastic are you OK to accumulate in your lungs/testes/placenta/blood/breast milk/brain?
- leereeves 3y agoDoes it accumulate or is it just a constant low concentration of plastic passing through the body?
