Never mind the plastic pipes in your home, there's nothing filtering the water from the treatment plant to your tap. Literally kilometres worth of pipes that haven't been cleaned in years or decades that your tap water is running through.
Not to mention that municipal water in Canada can be tainted with high levels of lead..
Bottled water may have "plastic particles", but some brands put their bottled water through reverse osmosis filtering, so it's way cleaner than your tap water.
And I am NOT advocating for drinking plastic bottled water, simply pointing out that tap water isn't really "clean" once it reaches your home. I filter all the water I consume.
I wouldnt be so quick to blame all of this on water bottles when a high percentage of all the food we consume is packaged in plastic and also the left overs sitting in the fridge.
"We and others have shown that these nanoplastics can be internalized into cells and we know that nanoplastics carry all kinds of chemical additives that could cause cell stress, DNA damage and change metabolism or cell function."
Somarelli said his own, yet-to-be-published work has found more than 100 "known cancer-causing chemicals in these plastics."
And also
What's disturbing, said University of Toronto evolutionary biologist Zoie Diana, is that "small particles can appear in different organs and may cross membranes that they aren't meant to cross, such as the blood-brain barrier."
My point being that it's unlikely that bottled water is the only source of these plastics.
Drink bottle water and consume plastic particles... drink tap water and get all the other contaminants (places I travel for work outside of Canada have highly contaminated and unsafe water... so water with bits of plastic are the lesser evil).
