Bottled water contains hundreds of thousands of nanoplastics: study

This stuff is just unavoidable:

"In what the researchers called an ironic finding, they also found plastic compounds in the water that matched the primary material in reverse-osmosis filters — suggesting that the plastics had leached into the water by the very process of filtration, co-author Naixin Qian of Columbia University told The Hill.

But the more dangerous particles like PVC and polystyrene seemed to have entered the plastic bottles with the “source water” that filled them, Qian said."
